What is email-agent-mcp?

A local email connection for AI agents that works with Microsoft 365 and Outlook mail through MCP. It supports reading, drafting, sending, and organizing messages.

Use it to read mail, prepare or send messages, and organize Microsoft 365 or Outlook email.

It removes the need to handle email manually or build a separate mail connection for each of those tasks.

Security

Grade A, and why

email-agent-mcp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

The scan reads gemini-extension.json. This mod also ships 12 executable files (scripts/bump_version.mjs, scripts/check-gemini-extension-manifest.mjs, scripts/check-isolated-runtime.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
