How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

Unverified: 5 categories

Categories scored 0 because our sandbox has not given us the schema these checks need to read. That is a gap on our side rather than a finding about the package, and we only credit what we can confirm, so the score stands at 0 until the capture succeeds. We are working through the fleet, so this normally clears without any action from you. How we score packages →

MCP tools

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tools for package channels are captured by running the package in an isolated sandbox. The most recent sandbox run could not capture a tool list from this package.

Common questions

What is the Pidgeon MCP server?

Pidgeon is an MCP server listed in the public MCP registry as ai.pidgeon/mcp. Mailboxes for AI agents: create addresses, send, receive, thread and hand off email. This page covers its npm package (@pidgeon-ai/mcp).

Is the Pidgeon MCP server safe to use?

Pidgeon scores 49 out of 100 on VerifyMCP. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

Is the Pidgeon MCP server still maintained?

Pidgeon is still listed as active in the MCP registry. We last reached this channel on 16 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What licence is the Pidgeon MCP server under?

Pidgeon declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
