41/100

Muninn

Provides persistent memory for AI coding agents via MCP, allowing them to recall fragility, decisions, and bugs across sessions.

Warning. Serious findings were identified. Review the full report before connecting. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

// key findings
🚨
Code appears obfuscated
1 file are unreadable to a human reviewer. Cannot audit what they do.
⚠️
Known vulnerabilities in dependencies: 4 high
Affects packages this MCP installs at runtime. Upgrade or remove the affected dependency.
🔐
You'll be asked for 2 credentials: MUNINN_API_TOKEN, MUNINN_AUTH_TOKEN
These are read from process.env at runtime. Make sure you trust where they’ll be sent.
// tools this server exposes4 tools

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.

recall

Your memory. One tool for all context. Give it files (pre-edit warnings), a query (search memory), or a task (planning context). Returns fragility, co-changers, decisions, learnings, issues, blast radius — everything you need in one call.

remember

Record a decision or learning. Natural language — auto-categorizes as decision or learning based on content. Use for novel insights only; routine file knowledge is captured automatically.

track

Track issues. Actions: add (record bug/debt), resolve (mark fixed).

muninn

Run a muninn command. Available: status, reindex, db, fragile, outcome, list, show, search.

Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

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

4/4 tools missing one or more hints — recall (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); remember (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); track (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +1 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 eval / new Function

1 eval() or new Function() call — dynamic code execution

Replace eval / Function with explicit parsing or safer alternatives.

Shell command execution

7 calls in production code run through a shell (src/commands/git.ts:37, src/commands/git.ts:51, src/commands/git.ts:71)

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

Readable source code

1 file are minified or bundled, which is usually build output rather than concealment

Ship unminified, readable source.

Production dependencies are patched

0 critical, 4 high severity in production deps — @modelcontextprotocol/sdk@1.25.3 (high), drizzle-orm@0.45.1 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

// 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 6 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
