You'll be asked for 3 credentials: GITHUB_TOKEN, VLLM_API_KEY, ANTHROPIC_API_KEY
These are read from process.env at runtime. Make sure you trust where they’ll be sent.

To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.

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

77/77 tools missing one or more hints — memory_add (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); memory_search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); memory_list_all (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +74 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.

Destructive tools are labelled

9 tools perform destructive updates without destructiveHint — memory_add deletes at line 355 (os.remove(os.path.join(MEMORY_DIR, f"{stale['name']}.md"))); memory_delete deletes at line 490 (os.remove(os.path.join(MEMORY_DIR, f"{name}.md"))); memory_clear deletes at line 512 (os.remove(os.path.join(MEMORY_DIR, f"{e['name']}.md")))

Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.

Shell command execution

1 call in production code run through a shell (mimir/vscode-extension/src/extension.ts:777)

Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.

Secrets stay with their owner

1 secret sent to a request target we could not resolve (VLLM_API_KEY → dynamic) — often a configured endpoint, not necessarily third-party

Audit where credentials are sent. A NOTION_TOKEN should only reach api.notion.com — never a third-party host.

// 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.
