What it does

A community MCP server for OpenSpec, a spec-driven development framework from Fission AI that has the user and an AI agree on a written spec before code is written. It runs locally through npx and exposes the OpenSpec command-line tool's functions as 34 tools: listing, showing and validating changes and specs, archiving changes, tracking tasks parsed from tasks.md, requesting and approving changes, adding and resolving review comments, creating changes from templates, generating proposals, setting up git hooks and reading design documents from other services. An optional web dashboard adds a Kanban board, approvals and reviews with live updates. It needs Node.js 20 and the OpenSpec CLI installed globally.

Capabilities

  • List, show and validate OpenSpec changes and specs
  • Track and update tasks from tasks.md
