Tools (4)
Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].
check_packagePre-install supply-chain gate for a single npm or PyPI package. Call BEFORE running npm install, pip install, or adding a dependency to package.json. Returns OK | SUSPICIOUS | DANGER (DANGER ~= NO-GO) with typosquat/slopsquat/hallucination flags. Read-only: queries public registries only; does not install anything. Do NOT use for full lockfile audits (use verify_lockfile) or CVE-only scans (use npm audit/OSV). If verdict is SUSPICIOUS or DANGER, stop and ask the user before installing.
check_workflowValidate CI workflow YAML (GitHub Actions / GitLab CI) BEFORE merging a PR that touches .github/workflows or GitLab CI. Call when reviewing or authoring CI pipelines. Flags mutable action pins (@v1), known-compromised actions, untrusted owners, curl|bash fetch-exec, pull_request_target pwn-request patterns, and secret exposure. Returns risk 0-100 and PROCEED | REVIEW | BLOCK. Read-only. Do NOT use for dependency lockfiles (use verify_lockfile). Default platform: github-actions. CI-workflow coverage is unique to agent-guard.
score_manifestScore a third-party AI-agent extension manifest (skill/plugin manifest audit) BEFORE install. Call BEFORE installing a Cursor skill, Claude skill, MCP server package, or Smithery plugin. Detects poison/backdoor signatures, credential scope over-reach, and drift vs an approved baseline. Returns risk 0-100 and PROCEED | REVIEW | BLOCK. Supports manifest_type: cursor-skill | claude-skill | mcp-server | smithery-package. Read-only. Do NOT use for npm package names alone (use check_package). If BLOCK, refuse install until the user reviews findings. This skill/plugin coverage is unique to agent-guar…
verify_lockfileScan an entire lockfile (direct + transitive deps) BEFORE npm/pip/yarn/pnpm install. Call when the user pastes or generates a lockfile, or before trusting an LLM-written package-lock.json / yarn.lock / pnpm-lock.yaml / poetry.lock / requirements.txt. Returns per-package OK | SUSPICIOUS | DANGER counts and flagged names. Read-only; pass raw file text, not a filesystem path. Do NOT use for a single new package (use check_package) or CI YAML (use check_workflow).
