Trust breakdown (6 categories)

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score →

Supply Chain Security87
  • No malware found by supply-chain analysis.Pass
  • Only part of the dependency tree could be resolved (129 of 130), so this covers what we could see, not the whole tree.Partial
  • No install/post-install scripts declared.Pass
  • Only part of the dependency tree could be resolved (129 of 130), so this covers what we could see, not the whole tree. View diagnostics → Partial
Provenance & Transparency45
Schema Quality & AI Usability77
  • AI-judged instruction clarity (excellent).Pass
  • Tool/resource definitions use about 806 tokens (~100/item across 8 items; 8 tools + 0 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
  • Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

MCP tools — 8 exposed · ~806 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

Tool Tokens
memory_export ~147

Dump the memory store as JSON, JSONL, or Markdown. Optional since/until window on updated_at. Use for backup/inspection. Requires explicit_user_intent: true.

NameTypeReqDescription
explicit_user_intentbooleanyesMust be true. Set ONLY when the current user message explicitly asks the agent to modify memory (set/forget/export). Do not infer intent.
formatstringyesOutput format: json (single object), jsonl (one entry per line), markdown (human-friendly).
sinceintegerUnix ms timestamp — include only entries with updated_at >= since.
untilintegerUnix ms timestamp — include only entries with updated_at <= until.

No output schema declared.

No examples provided.

memory_forget ~98

Delete a single key from memory. Idempotent: returns existed=false if the key was not present. Requires explicit_user_intent: true.

NameTypeReqDescription
explicit_user_intentbooleanyesMust be true. Set ONLY when the current user message explicitly asks the agent to modify memory (set/forget/export). Do not infer intent.
keystringyesStable identifier for the memory entry. Free-form text. Treat as case-sensitive.

No output schema declared.

No examples provided.

memory_forget_by_tag ~80

Delete every entry carrying the given tag. Returns deleted_count. Requires explicit_user_intent: true.

NameTypeReqDescription
explicit_user_intentbooleanyesMust be true. Set ONLY when the current user message explicitly asks the agent to modify memory (set/forget/export). Do not infer intent.
tagstringyesTag to bulk-delete.

No output schema declared.

No examples provided.

memory_get ~54

Exact key lookup. Returns the stored value plus timestamps, ttl, tags, metadata. Returns null if missing or expired.

NameTypeReqDescription
keystringyesStable identifier for the memory entry. Free-form text. Treat as case-sensitive.

No output schema declared.

No examples provided.

memory_list ~82

List keys with optional prefix or tag filter. Returns keys + timestamps + tags only — call memory_get for values. Use this first on a new session to discover what is stored.

NameTypeReqDescription
limitintegerMax keys to return.
prefixstringOnly return keys starting with this string.
tagstringOnly return keys carrying this tag.

No output schema declared.

No examples provided.

memory_search ~118

Full-text search across keys, values AND tags. Uses an FTS5 index with bm25 relevance ranking (key-weighted), word-stemming, diacritic folding and prefix matching — so multi-word, partial and accent-insensitive queries all hit, ranked by relevance. Falls back to a LIKE substring scan if the SQLite build lacks FTS5. Returns top N matches with a snippet. Case-insensitive.

NameTypeReqDescription
limitintegerMax matches to return.
querystringyesKeyword query. Matched against keys and values.

No output schema declared.

No examples provided.

memory_set ~190

Create or update a key in memory. Rejects credential-shaped keys or values. Requires explicit_user_intent: true. Returns whether the row was created or updated.

NameTypeReqDescription
explicit_user_intentbooleanyesMust be true. Set ONLY when the current user message explicitly asks the agent to modify memory (set/forget/export). Do not infer intent.
keystringyesStable identifier for the memory entry. Free-form text. Treat as case-sensitive.
metadataobjectOptional small JSON object with provenance/notes. Subject to same secret-detection rules.
tagsarrayOptional list of tags for grouping/filter/bulk-delete.
ttl_secondsintegerOptional TTL in seconds. After this, the entry is lazy-deleted on next read.
valueyesThe value to store. Will be JSON-serialized. Rejected if it looks like a credential.

No output schema declared.

No examples provided.

memory_stats ~37

High-level stats about the local memory store. Safe to call first on every session to gauge whether the store is empty, small, or large.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.
