Rebar MCP Server

An event-sourced, git-backed ticket store + Jira reconciler built for agent swarms - one store, exposed as a Python library, a CLI, and an MCP server. It runs locally over stdio via the published package.

People connecting developer tools tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Rebar

before you install - you'll need

REBAR_ROOT

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add navapbc-rebar -- uvx nava-rebar

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "navapbc-rebar": {
      "command": "uvx",
      "args": [
        "nava-rebar"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
