What is the Reprompt MCP server?

X-ray your AI coding sessions across Claude Code, Cursor, ChatGPT, and 6 more tools. Discover your patterns, find wasted tokens, catch leaked secrets — all locally, nothing leaves your machine. Exposed over MCP by the reprompt mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

  • 100% local — — your prompts never leave your machine
  • No LLM required — — pure rule-based analysis, <50ms per prompt
  • 9 AI tools — — the only tool that works across Claude Code, Cursor, ChatGPT, and more
  • Research-backed — — calibrated against 10 peer-reviewed papers, not vibes

Its toolset

Everything the assistant can do here goes through one of these:

  • Cursor — .vscdb
  • Aider — Markdown
  • ChatGPT — JSON
  • Claude.ai — JSON/ZIP
  • Manage — The Manage tool exposed by this server

Adding it to your client

Installation goes through your MCP client rather than a global install: point it at ctxray on PyPI and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

When to reach for it

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Reprompt's toolset — Cursor, Aider, ChatGPT and 2 more — is a fair guide to whether it matches your workflow. It is maintained by reprompt-dev; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Reprompt's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Caveats

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the reprompt mcp server does with a few real requests.
