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 | $0.00273 | $0.00273 |
| Opus 5.5 | $0.00109 | $0.00109 |
| Sonnet 5.5 | $0.00055 | $0.00055 |
| Haiku 4.5 | $0.00027 | $0.00027 |
Grade A, and why
imap-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 2mo 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.
This is a copy
100% identical to imap-mcp CLAUDE.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
This project is an IMAP Model Context Protocol (MCP) server to expose IMAP operations as tools for AI assistants. It uses:
- MCP SDK: Model Context Protocol for creating tools that can be used by AI assistants
- IMAP client libraries for interacting with email servers
Environment Setup
The project requires the following environment variables:
IMAP_HOST=<IMAP host>
IMAP_PORT=<IMAP port>
IMAP_USERNAME=<IMAP username>
IMAP_PASSWORD=<IMAP password>
IMAP_USE_SSL=<IMAP ssl option>
Common Commands
# Install dependencies
npm install
# Compile TypeScript to JavaScript
npx tsc
# Run the MCP server
node index.js
Project Architecture
The codebase is an MCP server implementation that:
- Connects to an IMAP server using credentials from environment variables
- Exposes IMAP operations as MCP tools for AI assistants
- Available tools: TBD (to be determined)
The MCP server uses the StdioServerTransport to communicate through stdin/stdout, making it suitable for integration with Claude or other AI assistants that support the Model Context Protocol.
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.
