What is email-mcp CLAUDE.md?

Project instructions for email-mcp, an email service that supports sending and receiving mail through services such as SMTP, IMAP, SendGrid, Mailgun, and Resend. They describe its entry points, response format, connection checks, and main files.

Understanding the email-mcp codebase, following its tool and response conventions, checking email connectivity, and working with inbox or mailing-list operations.

They give a coding agent the project's expected workflow and conventions before it changes the email service. They also specify checking connectivity and recent unread messages during a work session.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00268	$0.00268
Opus 5	$0.00134	$0.00134
Sonnet 5	$0.00054	$0.00054
Haiku 4.5	$0.00027	$0.00027

Security

Grade A, and why

email-mcp CLAUDE.md 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 6d ago.

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.

What it actually says

email-mcp -- Claude Code Guide

Overview

Multi-service email platform supporting SMTP/IMAP, SendGrid, Mailgun, Resend, local testing, and webhook integrations (FastMCP 3.2, Prefab UI)

Entry Points

uv run email-mcp → email_mcp.server:main

Standards

Responses: structured dicts with success, message, domain-specific fields
Dual transport: stdio (Claude Desktop) + HTTP (MCP_TRANSPORT=http)
See mcp-central-docs for fleet-wide coding standards

Session Context

Before starting work: call email_status() to check connectivity, then check_inbox(service="default", unread_only=True, limit=10) for recent activity
At end of work: send drafted emails, mark read, subscribe to mailing lists via mailing_list_latest()

Key Files

README.md -- full documentation
pyproject.toml -- build config and entry points
AGENTS.md -- Agent context

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.
