Install

npx mcp-pachca --setup

The wizard asks for the client, config scope, email and the emailed code.

This is third-party code. Review the repository files before installing.

What it does

The server gives the agent access to Pachca as your user account. The agent sees chats by folder, reads messages with pagination, searches all message text, lists unread chats, finds users by name or email, checks their presence and personal chat. It can also send a message to a chat. Setup runs through a wizard: you pick the client, enter your email and the emailed code, the session is saved locally and the MCP config is written automatically.

Who it is for. For employees at companies that use Pachca for work chat and want an agent to help go through unread messages.

Good fit when

  • You need a quick summary of unread chats
  • You need to find an old discussion by keywords
  • The agent needs team chat context while working on a task

Not a fit when

  • You need a bot with its own token rather than access as yourself
  • Chats contain data that must not be sent to a model

Example request

Which chats are unread and what is important there today?

Limitations

The server acts as the user via a session obtained with an emailed code and stores it in ~/.config/mcp-pachca/session.json. The setup wizard supports Claude Code and Cursor. The README is short and does not describe API limits or session lifetime. Community project, not a Pachca product.

How to disable. Delete the pachca block from .mcp.json or the global config and remove ~/.config/mcp-pachca/session.json.

The README describes a one-command install with a setup wizard for Claude Code and Cursor and a manual .mcp.json config. A table lists tools for users, chats, messages, search and presence. The development section shows building from source and a debug mode. MIT license.

FAQ

Do I need a bot token?

No, login uses your email and a six-digit code, and the server acts as your account.

How do I connect without the wizard?

After the first login you can add a block with npx -y mcp-pachca@latest to .mcp.json manually.
