mailpouch

An MCP server that gives AI agents permission-gated, audit-logged access to private email providers (Proton Mail via Bridge and plain IMAP), running locally with OAuth-based authentication and human-controlled escalation for destructive operations.

Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

// key findings
🚨
Secret credentials may flow to a network call
2 flows detected: GITHUB_API_URL. We can’t prove the destination matches the brand the credential belongs to.
🔐
You'll be asked for 3 credentials: GH_TOKEN, GITHUB_TOKEN, MAILPOUCH_MACHINE_SECRET
These are read from process.env at runtime. Make sure you trust where they’ll be sent.
// 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.

All four hints declared on every tool

86/86 tools missing one or more hints — mark_email_read (missing: openWorldHint); star_email (missing: openWorldHint); mark_answered (missing: openWorldHint), +83 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 test coverage

50/86 tools referenced in tests (58%)

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

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

31 child_process calls — runs shell commands

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

No arbitrary install scripts

Has postinstall/preinstall script — runs arbitrary code on npm install

Remove postinstall/preinstall hooks unless they’re essential.

Domain consistency

npm scope @mailpouch doesn't match GitHub owner chandshy

Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.

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