Tools (31)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • add_observationsAdd Observations

    Add new observations to existing entities in the knowledge graph Backed by a Particles store: an item identical to one deleted earlier, or one that conflicts with a stored belief, is held for review rather than added. It is left out of the result, and an extra text block names it.

  • corpus_links_suggest
  • create_entitiesCreate Entities

    Create multiple new entities in the knowledge graph Backed by a Particles store: entity names match case-insensitively, so a name differing from an existing entity only by case is treated as that entity and skipped. Backed by a Particles store: an item identical to one deleted earlier, or one that conflicts with a stored belief, is held for review rather than added. It is left out of the result, and an extra text block names it.

  • create_relationsCreate Relations

    Create multiple new relations between entities in the knowledge graph. Relations should be in active voice Backed by a Particles store: an item identical to one deleted earlier, or one that conflicts with a stored belief, is held for review rather than added. It is left out of the result, and an extra text block names it.

  • delete_entitiesDelete Entitiescan change or delete data

    Delete multiple entities and their associated relations from the knowledge graph Backed by a Particles store: this retracts with an audit trail rather than hard-deleting, so the item stops appearing in reads while its history survives.

  • delete_observationsDelete Observationscan change or delete data

    Delete specific observations from entities in the knowledge graph Backed by a Particles store: this retracts with an audit trail rather than hard-deleting, so the item stops appearing in reads while its history survives.

  • delete_relationsDelete Relationscan change or delete data

    Delete multiple relations from the knowledge graph Backed by a Particles store: this retracts with an audit trail rather than hard-deleting, so the item stops appearing in reads while its history survives.

  • deposit_text

    Deposit a literal string as one corpus entry; no fetch, no extraction. ``project_key`` is the project a bound agent surface writes as. It is the server's to supply, never the caller's: on the agent path it replaces any ``project:`` tag in ``tags``. Two callers with deliberately different attribution: * **Agent (cheap deposit)** — both arguments omitted. The entry is attributed to the server-bound asserter identity and typed ``CONVERSATION``, so it lands under the §6.4 AUTHOR trust tier that ranks agent-asserted content below operator content. * **Operator (the CLI ``deposit --text`` h…

  • event_show
  • events_list
  • link_add

    Link two particles with a typed relation (CO_EVIDENTIAL today). A thin mirror of ``particles links add``; particles are addressed by full id. On a project-bound server the two beliefs must already have the same observer scope: a link between different scopes would change which projects see them, which is the operator's act (``particles links add``). Args: particle_a: Full id of the first particle. particle_b: Full id of the second particle. relation_type: Relation kind; only ``CO_EVIDENTIAL`` is emittable over MCP today. store: Target store handle; required only when several …

  • link_remove

    Remove a typed relation between two particles. Mirror of ``particles links remove``. Args: particle_a: Full id of the first particle. particle_b: Full id of the second particle. relation_type: Relation kind; only ``CO_EVIDENTIAL`` is emittable over MCP today. store: Target store handle; required only when several are write-enabled.

  • links_suggest
  • lint
  • list_corpus_entries
Show 16 more tools
  • list_taxonomies
  • open_nodesOpen Nodesread-only

    Open specific nodes in the knowledge graph by their names Backed by a Particles store: results are capped for context safety and any truncation is disclosed in an extra text block.

  • particle_assert
  • particle_retract
  • particle_search

    List particles sharing a context fingerprint. Args: fingerprint: Full 64-char SHA-256 hex or a prefix (≥ 8 chars). limit: Maximum particles to return (default 50, capped at 200 to keep responses within MCP per-tool-result token caps — fingerprint matches share full ``content`` strings). all_projects: On a server bound to one project, read the whole store instead of that project's view. The result says so. No effect on an unbound server. Returns: Dict with ``fingerprint`` (the queried value) and ``particles`` (list of ``{id, status, content}…

  • read_graphRead Graphread-only

    Read the entire knowledge graph Backed by a Particles store: results are capped for context safety and any truncation is disclosed in an extra text block. Entities are returned in name order, not creation order.

  • search_nodesSearch Nodesread-only

    Search for nodes in the knowledge graph based on a query Backed by a Particles store: results are capped for context safety and any truncation is disclosed in an extra text block.

  • subjects_list
  • subjects_search
  • subjects_show

    Show one subject with the particle IDs linked to it. Args: subject_id: A full UUID, an unambiguous prefix (≥ 8 chars), or a name or alias, matched case-insensitively and exactly. A reference that matches more than one subject (a prefix shared by several IDs, a name two subjects share, or a string that is both a prefix and a name) raises with the candidates named. A remote engine resolves IDs and prefixes only. particle_id_limit: Maximum particle IDs to include in ``particle_ids`` (default 100). For hot subjects the full list can …
