Kagura Memory Cloud

Soft-delete memories that are outdated, incorrect or no longer needed. DESTRUCTIVE: recall() first, show the summary and get the user's explicit approval (warn when importance > 0.8). To replace a fact instead, use remember(supersedes=...). Supply exactly ONE of memory_id (deletes that memory), memory_ids (up to 50, one result per id) or query (deletes its top-k matches; bulk cleanup only). Deleted memories stay recoverable for the deployment's cleanup window (default 30 days). Returns: {status, deleted_count, memory_ids, session_id?, context_id, context_name}; a target you may not delete, or …

Get a context's most recent succeeded analysis run, or error no_succeeded_run when it has none yet. Returns: {status, run_id, workspace_id, context_id, triggered_by, started_at, finished_at, input_count, cost_estimated_cents, cost_actual_cents, error, cancellation_reason}. The cost_* keys are absent when the deployment disables cost display.

Fetch one registered agent by id (owner/admin only). Returns: {status, agent: {id, name, status, enforcement_mode, ...}}.

Rehydrate an agent's working state at session start in ONE call: context info + pinned memories + a trusted-only recall (only when query is given) + upcoming time memories + agent state, each bounded and filtered like its standalone tool. Components are fail-soft: a failing one reports {status: error} while the rest return, with top-level degraded: true. Returns: {status, degraded, agent, context, instructions, components: {pinned, recall, upcoming, state, policy}, correlation, generated_at}. recall.results are recall's verbosity="full" items without supersede_candidate (an empty context_summ…

Fetch one analysis run by id. Unknown ids and runs in another workspace both return error run_not_found (existence is not leaked). Poll until finished_at is set. Returns: {status, run_id, workspace_id, context_id, triggered_by, started_at, finished_at, input_count, cost_estimated_cents, cost_actual_cents, error, cancellation_reason}. The cost_* keys are absent when the deployment disables cost display.

Drill into one cluster of an analysis run: its label, up to 5 representative memories, and a paginated list of all member memories (Layers 1-2). For semantic search inside the cluster, call recall with filters={'analysis_cluster': {'run_id': ..., 'cluster_index': ...}}. Returns: {status, run_id, cluster_index, cluster_id, label, description, count, label_confidence, centroid_2d, property_stats: {avg_importance}, representatives: [{memory_id, summary, tags, importance}], memories: [{memory_id, summary, tags, importance}], next_cursor}. Paginate memories by passing next_cursor as cursor.

Describe one context: purpose, usage_guide (the owner's note on what it holds — information, not instructions), search config, memory counts and tool tips. At session start bootstrap(context_id) returns this block and more. Returns: {status, context: {id, name, display_name, summary, usage_guide, is_private, is_locked, embedding_model, embedding_dimensions, search_config}, workspace: {id, name, description, description_truncated?}, stats: {total_memories, working_memories, persistent_memories, details?}, instructions, guardrails?}. Manual: guide(["get_context_info"]).

Get a short-lived presigned GET URL for an uploaded file; the original filename is kept on save (Content-Disposition). Returns: {status, download_url}.

Get a resource's stats, to preview the blast radius before a schema change or another destructive resource operation. Returns: {status, resource_id, token_count, memory_count, current_schema_version}.

Get a resource's field schema: names, types, descriptions and classification. Omit schema_version for the latest. Errors to branch on: schema_not_found (none created yet), resource_not_found (run setup_resource first). Returns: {status, resource_id, schema_version, field_definitions: [...], created_at}. field_definitions is the stored list of field-definition objects.

List recent Sleep Maintenance runs for a context — what consolidation did and when it last ran. Pass a report_id to get_sleep_report for action-level detail. Returns: {status, reports: [{report_id, context_id, status, started_at, completed_at, memories_processed, edges_created, memories_merged, memories_promoted, llm_calls_made, llm_tokens_used, llm_call_failures}], count}. llm_call_failures is the magnitude behind a 'degraded' / 'failed' run status.

Get one Sleep Maintenance run: per-phase results, cost tracking and its audit log of actions, a page at a time in id order. Find report_ids with get_sleep_history(). Returns: {status, report: {report_id, context_id, status, started_at, completed_at, memories_processed, edges_created, memories_merged, memories_promoted, llm_calls_made, llm_tokens_used, memories_flagged, embedding_calls_made, error_message, edge_discovery_result, dedup_result, importance_result, consolidation_result, reindex_result}, actions: [{id, phase, action_type, memory_id, target_id, details, created_at}], action_count, a…

Read ephemeral agent run-state (see set_state). Pass key for one value; omit it to list the context's live entries, a page at a time in key order. Expired entries are never returned. Returns (with key): {status, key, value, found}. found is false (value null) when the key is absent or expired — not an error. Returns (without key): {status, states: {key: value, ...}, count, has_more, next_cursor, omitted_keys?}. An empty states object with count 0 is a normal success. has_more: pass next_cursor as cursor for the next page. omitted_keys: values too large for this reply — read each with key.

Get the current workspace's usage against its effective limits (plan tier + addons), e.g. to check quota before bulk operations. Returns: {status, plan, memories: {used, limit, percentage}, contexts: {used, limit}, members: {used, limit}, mcp_calls_per_day: {used, limit}, capacity_lock}. capacity_lock is null unless the workspace is over its Free capacity; then {over_memories, over_bytes, cleanup_url, help, ...}, and search and saving answer capacity_locked until it is cleaned up.

Return the manual for these tools on demand: how to read a response, when to pick one tool over its neighbour, the write rules. Pass tool names ("recall", "remember") or sections ("recall.reading-results"); guide(["index"]) lists every topic. Read once per session — the text is static. Returns: {status, topics: [{topic, text}], unknown?, hint?}.

Batch-ingest resource events (upsert / delete): max 100 events per call, 100KB per payload. Triggers incremental indexing for every context bound to the resource. Session-authenticated (no resource token); for bulk imports (10k+ records) use the CLI or SDK. Example: ingest_events(resource_id='ec_products', events=[{'op': 'upsert', 'doc_id': 'PROD-1', 'version': 1, 'payload': {'name': '...'}}, {'op': 'delete', 'doc_id': 'PROD-999'}]) Returns: {status, resource_id, created_count, failed_count, event_ids, errors: [{index, doc_id, error}]}. Partial success is possible — check failed_count / erro…

Reserve storage quota and get a presigned PUT URL for a file upload (max 100 MiB; the workspace storage limit is enforced). Compute the sha256 first: if the workspace already holds a file with that sha256, a conflict error names its file_id — reuse it. Returns: {status, file_id, upload_url, expires_at}. Next: PUT the bytes to upload_url, then call complete_file_upload(file_id).

List a context's live memories that match exact filters — every match, no ranking, stable pages, e.g. {"type": "task", "details.status": "open"}. recall() is for meaning. Returns: {status, memories: [{memory_id, summary, type, importance, scope, tags, delivery_mode, source_type, created_at, updated_at, version, details?}], count, total, has_more, next_cursor, order_by, direction, truncated?, details_omitted?, context_{id, name, display_name, is_private, is_locked}}. Manual: guide(["list"]).

List an agent's context bindings (owner/admin only). Returns: {status, bindings: [...], count}.

List the workspace's registered agents, newest first (owner/admin only), with status (active | suspended | retired) and enforcement_mode (shadow | enforce). Returns: {status, agents: [...], count, total_available, has_more, next_cursor}. description is a 200-character preview (description_truncated: true when cut; get_agent has it whole). has_more: pass next_cursor as cursor.

List a context's analysis runs, newest first. Cursor-paginated: pass next_cursor as cursor until it is null. Returns: {status, items: [{run_id, workspace_id, context_id, status, triggered_by, started_at, finished_at, input_count, cost_estimated_cents, cost_actual_cents, error, error_truncated?, cancellation_reason}], next_cursor}. error is a 300-character preview (error_truncated: true when cut; get_analysis has it whole). A page stops at 20,000 characters. The cost_* keys are absent when the deployment disables cost display.

List the contexts you can access as a slim name→id directory, most recently used first. Other tools need context_id unless the URL sets ?context=. Narrow with name_contains; get_context_info(context_id) for one context's details. Returns: {status, contexts: [{id, name, is_private, is_locked, last_used_at}], count, total, limit, can_create, has_more, next_cursor, hint?}; pass next_cursor as cursor for the next page. Manual: guide(["list_contexts"]).

List the graph edges connected to a memory, outgoing and incoming — to inspect its connections, audit edges created by Sleep Maintenance, or find a noisy edge before delete_edge() (min_weight=0 shows the weak ones). Returns: {status, memory_id, edges: [{source_id, target_id, edge_type, weight, confidence, origin, created_at, last_updated}], count, min_weight, outgoing_has_more, incoming_has_more}. Heaviest first; a *_has_more of true means more edges exist in that direction — raise min_weight or narrow edge_types.

List uploaded, non-deleted files you can access in the workspace, newest first. Returns: {status, files: [{id, context_id, filename, content_type, size_bytes, sha256, status, created_at, uploaded_at}], count, has_more, next_cursor}. has_more: pass next_cursor as cursor for the next page.

List the public-bound API keys you own: keys attributed to one public (is_public=true) context for per-key rate limit, audit and revoke. Revoked keys are excluded. Read-only — mint and revoke via the SDK / CLI / HTTP API / dashboard. Returns: {status, bindings: [{key_id, name, context_id, context_name, created_at}], count}. An empty list (count 0) is a normal success. key_prefix is only on describe_binding.

List the workspace's resource tokens (owner or admin only). Metadata only — plaintext tokens are never returned. Returns: {status, tokens: [{id, resource_id, description, quota_events_per_hour, is_active, created_at, last_used_at}], total, limit, offset}.

List one memory's revision log, newest first: created, updated (with the fields the edit changed), forgotten and restored events, each with the version after it. Read an earlier version with reference(memory_id, version=N); revert with update_memory(expected_version=current_version) and the old values. Sleep maintenance and connector re-indexes write no events (they never move the version). Returns: {status, memory_id, current_version, revisions: [{version, kind, at, changed_fields, writer, by_you, agent_id?, session_id?}], count, has_more, next_cursor, truncated?, context_id, context_name, co…

List a context's tag vocabulary with usage counts and recency. Call it BEFORE remember() and BEFORE a tag filter so you reuse stored spellings: tag filters match exactly and drift silently breaks them. Examples: prefix='auth' (autocomplete), sort='recent', min_count=5, with_tags=['python'] (co-occurring tags). Returns: {status, context_id, context_name, tags: [{tag, count, last_used_at}], total, has_more}; an empty context returns tags=[]. Manual: guide(["list_tags"]).

Load a context's guardrail set — stored notes by context members — for a client-side hook: pinned memories (delivery_mode='always') plus memories marked with details.tool_trigger = {tool, on, match?, action}. Deterministic and cheap — no search, no ranking — trusted-tier rows only (connector-ingested memories are never returned). Each list is ordered importance DESC, created_at ASC, id ASC and capped on its own; cap bounds tool_triggered only, so a large pinned set never crowds guardrails out. The server validates tool_trigger patterns on write and never runs them; matching happens in the clie…

Load a context's pinned memories (delivery_mode='always'): the complete, unranked set on every call — the deterministic counterpart to recall(). Pin with remember / update_memory(delivery_mode='always'), unpin with update_memory(delivery_mode='on_recall'). Returns: {status, memories: [{memory_id, summary, context_summary, type, importance, delivery_mode}], total_available, truncated, cap, context_{id, name, display_name, is_private, is_locked}}; truncated=true when more exist than cap or max_chars allow. Manual: guide(["load_pinned"]).

Copy every memory from a source context into a target context, e.g. to fold a test context into production. Copied, not moved: the source keeps its memories unless delete_source=true, which soft-deletes the source with its memories; the source's files move to the target with them. Both contexts must be in the same workspace and use the same embedding model; requires owner access to both. Returns: {status, message, merged, source_id, target_id, delete_source}. source_id / target_id here are CONTEXT UUIDs, unlike the edge tools, where they are MEMORY UUIDs.

Search a context's memories by meaning and keywords (hybrid semantic + BM25); returns ranked summaries, plus content for the top `full`. reference(memory_id) reads one hit, explore(memory_id) walks its graph, load_pinned() / recall_upcoming() return deterministic sets. Query with the expected answer ('JWT expiry caused 401'), not the question. Read confidence.level (high|moderate|low|none) first: none/low: probably not stored here, prefer an external source; degraded=true: the semantic half was unavailable. Searches may also strengthen associations (not keyword-only or degraded recalls) and pr…

List memories near a geographic point, nearest first with distance_m. Use for 'what happened around here?' questions. A deterministic spatial query over stored coordinates (details.location), NOT semantic search — for topics use recall(). Store a location on any memory type with remember(details={'location': {'lat': 35.68, 'lon': 139.76, 'label': 'optional'}}); lat/lon must be JSON numbers. update_memory replaces details wholesale — resend location or it is dropped. Returns: {status, results: [{memory_id, summary, type, location, distance_m}], context_id, context_name, context_display_name, c…

Read one metric's measurement series (see record_measurement), bucketed by period and aggregated per bucket. A deterministic query, not search. Empty buckets are omitted. Default window: the last 30 days; max 365 days per call. Returns: {status, metric, period, agg, series: [{bucket, value, count}], count}. bucket is the ISO start of the period; count is the number of observations in it.

List Time Memories (type='time') whose scheduled window overlaps a range, soonest first — a deterministic time query, not search (topics: recall()). Create one with remember(type='time', details={'trigger': {'year': 2026, 'month': 7}}). Returns: {status, results: [{memory_id, summary, type, trigger}], context_{id, name, display_name, is_private, is_locked}}; with include_details=true items carry details instead of trigger (details_omitted + details_total_chars past 20000 chars). Manual: guide(["time-memories"]).

Append one numeric observation to a metric's series (weight, revenue, reps, ...). For raw numbers, NOT prose — use remember() for notes such as 'hit goal weight'. Append-only: nothing is upserted. Measurements are not memories: never embedded, never returned by recall(), never touched by Sleep consolidation. Read them back with recall_series. Returns: {status, measurement_id, metric, measured_at, value, unit}.

Read one memory in full by id, within max_chars; version=N reads an earlier version. Use it after recall(), which returns summaries only. Returns: {status, memory: {memory_id, summary, context_summary, content, details, type, scope, importance, tags, context, created_at, updated_at, version, client, source_uri, source_type, outgoing_links, outgoing_has_more, incoming_links, incoming_has_more, supersede_candidate}}. supersede_candidate is an older near-duplicate (a suggestion): accept with update_memory(accept_supersede_candidate=true); create_edge(edge_type="supersedes"), outside the core prof…

Register an AI agent in the workspace Agent Registry (owner/admin only): an entry that anchors context bindings, agent-bound credentials, bootstrap and audit correlation. It is a resource, NOT a principal — it never authenticates by itself. New agents start with status='active' and enforcement_mode='enforce'. Returns: {status, agent: {id, name, status, enforcement_mode, ...}}.

Store a new memory (a decision, fix, pattern, fact or note) for later recall. To edit a memory whose id you have use update_memory; to replace an outdated fact pass supersedes=<old_memory_id>. Write summary as the reusable conclusion with the terms a future search would use; content holds the full text. SECURITY: never store secrets, credentials or PII — refuse and ask the user to redact; coordinates go only in details.location, never in context. Returns: {status, memory_id, scope, version, persistence?: {scope, committed, promotes_via, consolidation_archive_min_age_days}, lint?, session_id?, …

Store up to 50 memories in one call — the end-of-session save. Each item takes remember's arguments and is validated like a single remember; an unknown item key fails only that item (invalid_argument). atomic=false (default): items are written independently and reported per item. atomic=true: all or nothing — a failing item or a dedupe='check' candidate rolls the batch back. Returns: {status: success|partial|duplicate_candidate, results: [{index, status: success|error|skipped|duplicate_candidate, memory_id?, scope?, persistence?, lint?, error?, message?, candidate?}], count, succeeded, candida…

Undo writes in a context: one session's (session_id), or your own in a time window (since, until?; ≤ 7 days — for clients without a session id). DESTRUCTIVE — dry_run=true (the default) only lists the plan. Per memory: created → forgotten; updated → the values from before the first edit put back (a new version); forgotten → restored and re-embedded. A memory changed by someone else since, merged by Sleep or a resource row is skipped with a cause, never half-reverted. Your own writes only (same user or a linked account, same agent credential); a context owner may name any session. Editor role. …

Reverse every recorded action of a finished Sleep Maintenance run. DESTRUCTIVE — use with care. create_edge → edge deleted; merge / archive → memory restored and re-embedded; update_importance → previous value restored; promote → scope back to 'working'. Only for reports with status 'completed' or 'degraded' (a degraded run still executed real merges); the report is then marked 'rolled_back', so it cannot be rolled back twice. Returns: {status, report_id, rollback_summary: {edges_deleted, merges_reversed, merges_unreversible, importance_restored, promotions_reversed, importance_kept, promoti…

Fetch an age-encrypted secret you have been granted. Returns OPAQUE CIPHERTEXT — decrypt it locally (age -d -i <key>); the server holds no key. Default-deny: you need an active grant via an approved pubkey. Every fetch is written to a tamper-evident audit log first. Returns: {status, name, version_number, alg, ciphertext, recipients_snapshot, rotation_needed}.

List secret names and metadata (owner/admin) — NEVER a secret value. rotation_needed=true means a grant was revoked and the upstream credential should be rotated. Returns: {status, secrets: [{name, status, rotation_needed, current_version, grant_count, created_at, updated_at}], count}.

Store an age-encrypted secret and grant recipients (owner/admin). The server only ever receives OPAQUE CIPHERTEXT: encrypt client-side first (age -r <recipient> ...) to exactly the granted recipients. NEVER pass a plaintext value. recipients_snapshot must match grant_pubkey_ids exactly, and every grant target must be an approved pubkey. An existing name gets a new version; its grants not listed in grant_pubkey_ids are revoked. Returns: {status, name, version_number, status, rotation_needed}.

Register YOUR age recipient public key so secrets can be shared with you. Generate the key pair locally (age-keygen) and register ONLY the public recipient (age1...). SECURITY: never send a private key (AGE-SECRET-KEY-...) anywhere. The key starts pending until a workspace owner approves it. Returns: {status, pubkey_id, fingerprint, status: 'pending'}.

Revoke a recipient's grant on a secret (owner/admin). Stops FUTURE fetches and flags the secret rotation_needed. Not retroactive: a recipient who already fetched the ciphertext may still hold it, so rotate the upstream credential afterwards. Returns: {status, name, rotation_needed: true}.

Upsert ephemeral agent run-state at (context_id, key): the current task, step, scratch flags. For transient state, NOT durable knowledge — use remember() for knowledge. State is not a memory: never embedded, never returned by recall(). Returns: {status, key}.

Provision an ai-worker chat-ingest connector: a resource, a connector row and a connector-scoped resource token in one operation. Owner or admin only, on a plan with the `connectors` feature (XL); existing connectors on lower plans keep working, and the max_connectors seat cap applies second. Returns: {status, message, connector_id, connector_type, resource_id, resource_pk, token_id, token, quota_events_per_hour, idempotency_key_prefix, context_id, kmc_api_key}. token and kmc_api_key are shown ONCE — store them now. Connector event idempotency keys must start with idempotency_key_prefix.

Create a public context plus a resource token in one atomic operation — the first step of a resource ingestion pipeline (then ingest_events). Owner or admin only, on a plan with the `resources` feature (XL); existing resources on lower plans keep working. Returns: {status, message, context_id, context_name, resource_id, token, token_id, warning}. token is shown ONCE — store it now.

Delete a binding (owner/admin only). Under enforcement_mode='enforce' the agent's requests against that context are denied afterwards (uniform context_not_found). Returns: {status, deleted, binding_id}.

Update a registered agent, including lifecycle transitions (owner/admin only). status is the fail-closed kill switch: every key bound to a 'suspended' or 'retired' agent is rejected. enforcement_mode 'enforce' → 'shadow' is an audited privilege-widening event: bindings are then only logged, not enforced. Returns: {status, agent, changed: [field, ...]}.

Update a binding's scoping fields (owner/admin only); see bind_agent_context for their meaning. context_id is immutable — unbind and re-bind to re-target. Changes are audited with old → new values. Returns: {status, binding, changed: [field, ...]}.

Update a context's settings. display_name and description need the context editor role; every other field is owner-only. Read the current values with get_context_info(). Returns: {status, message, updated_fields, context_{id, name, display_name, is_private, is_locked}}.

Change an existing edge's weight and/or type (any create_edge edge_type is valid). Identify the edge by source_id + target_id (from list_edges or explore); provide at least one of weight or edge_type. Returns: {status, edge: {source_id, target_id, edge_type, weight, confidence, origin, created_at, last_updated}}.

Update a memory in place (memory_id) or upsert by external_id (not found → created; found → replaced under a NEW memory_id; needs summary, content, type). Use it, not remember, to correct or enrich a memory whose id you have. SECURITY: never store secrets, credentials or PII — refuse and ask the user to redact; coordinates go only in details.location, never in context. details is replaced wholesale (resend details.location or it is dropped). Returns: {status, memory_id, operation, re_embedded, scope, version, persistence?, supersede_candidate_dismissed?, superseded_memory_id?, lint?, session_i…

Tune a context's search: hybrid weights, reranker, reinforce re-rank and query routing. Context owner or editor only (changing content_chunks_enabled or llm_selector_enabled: context owner or workspace owner/admin). semantic_weight + bm25_weight must sum to 1.0; a recall() that omits use_rerank follows this context's use_rerank. Example (keyless local reranking): use_rerank=true, reranker_provider='self_hosted' — reranker_model may be omitted. Returns: {status, message, context_id, config: {semantic_weight, bm25_weight, fetch_factor, use_rerank, reranker_provider, reranker_model, reinforce_e…
