These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

memory_search

Search your personal AI memory using semantic + full-text hybrid search.

memory_recall

Recall recent memories by category, project, and optional date.

memory_context

Get project context — meta + the FULL CONTENT of curated docs (identity / memory / plan / learning / note), plus a list of recent conversations. Conversation bodies are not inlined (they can be MB each) — use `memory_conversation(doc_id)` to drill into one, or `memory_blueprint(project_name)` for th…

memory_blueprint

One-shot project blueprint — everything you need to bring a fresh AI session up to speed on a project in a single tool call.

memory_store

Store a new observation or fact in your personal memory.

daily_summary

Get daily activity summary for a specific date.

memory_open

Fetch the full content of a document by its ID.

memory_conversation

Read the actual message-by-message contents of a conversation document.

memory_graph

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

21/21 tools missing one or more hints — memory_search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); memory_recall (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); memory_context (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +18 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

No hardcoded API keys

1 live-looking API key in source: 1 OpenAI API key

Move secrets to environment variables (process.env.X) or your secret manager.

Tool test coverage

Only 2/21 tools referenced in tests (10%)

Write tests that reference each tool by name so every tool has at least one test.

Secrets not logged

1 secret value sent to print

Redact or omit secret values from log output.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 5 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
