// key findings
✅
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
// environment variables
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.
configAUTH_BASE_URL
configAUTH_DCRon off → registration_endpoint is not advertised and /register is disabled (forces the preconfigured-client path).
configAUTH_PORT3002 Port of the authorization server.
configCALLBACK_HOST
configCALLBACK_PATH
configCALLBACK_PORT
configCLIENT_NAME
configDCR_ALLOWED_REDIRECT_URIS(empty = allow any) Comma-separated whitelist. When set, DCR rejects any redirect_uri not on the list.
configMCP_BASE_URL(origin of MCP_URL) Override for the origin used to build well-known URLs.
configMCP_ENDPOINT(path of MCP_URL) Override for the MCP endpoint path.
configMCP_PORT(from MCP_URL) Override for the MCP server's listen port.
configMCP_URLMCP_PORT (from ) Override for the MCP server's listen port.
configPRECONFIGURED_CLIENT_IDpreconfigured-client Static client_id available without registration (public client, no secret).
configPRECONFIGURED_REDIRECT_URIS
configTOKEN_TTL_SECONDS3600 Access token lifetime.
configWWW_AUTH_RESOURCE_METADATAon off → 401 challenges omit resource_metadata, forcing the client to construct the well-known URI itself.

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

1/1 tools missing one or more hints — echo (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint). 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.

License file

No license file

Add a LICENSE file (MIT, Apache-2.0, etc.).

Tests exist

No test files found

Add tests that exercise each declared tool.

Claim the listing to review these findings one by one and send us a correction where you disagree, straight to the team. Claiming also means we tell you when the grade moves, and reach you first if we find anything urgent.

// 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 4 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
