An open-source MCP server, API, and CLI for records, files, permissions, and reminders. Single binary, self-hosted.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
Hono JWK Auth Middleware has JWT algorithm confusion when JWK lacks "alg" (untrusted header.alg fallback)
hono: CORS Middleware reflects any Origin with credentials when `origin` defaults to the wildcard

JOURNAL_STREAMLOG_LEVELDATABASE_URLTool annotations
26/52 tools have annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
52/52 tools missing one or more hints — permissions_list (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); permissions_grant (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); permissions_revoke (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +49 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.
Tool inputs are validated
45/50 tool handlers declare input schemas (90%)
Declare an inputSchema with zod/joi/yup on every tool definition.
README present
No README found
Add a README.md describing the server and its tools.
License file

Add a LICENSE file (MIT, Apache-2.0, etc.).
Production dependencies are patched
0 critical, 5 high severity in production deps — hono@4.9.8 (high), hono@4.9.8 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dependency freshness
1/18 production deps stale: rrule@2023-11-10 (2.8y)
Domain consistency
npm scope @lastsaas doesn't match GitHub owner mkly
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
