StackBlitz MCP Server

About

An MCP server for reading files and project structure from StackBlitz projects, built by sxzz. Note this is a community project, not an official StackBlitz release — the previously-listed `stackblitz/mcp-server` repo does not exist. It exposes four tools: `resolve_project` looks up a StackBlitz project by ID or full stackblitz.com/edit/ URL and returns metadata (title, description, preset, visibility, file count); `list_files` renders the project's files as an ASCII tree, optionally filtered by a path prefix; `read_file` pulls the raw contents of a single file by path; and `search_files` runs a text or regex search across the project with case-sensitivity and result-limit options. It also exposes two MCP resource URI patterns — `stackblitz://{projectId}/tree` for the file tree and `stackblitz://{projectId}/files/{path}` for individual file contents — so an agent can browse a StackBlitz reproduction repo the same way it would a local directory. The server is read-only (no file writing or sandbox execution) and requires no API key, since it works against StackBlitz's public project data. It's aimed at the common "someone shared a StackBlitz repro link, now debug it" workflow: paste the project ID into Claude/Cursor and let the agent inspect the code directly instead of you copy-pasting files by hand. Install via npm as a global CLI (`stackblitz-mcp`) and wire it into any MCP-compatible client's config.
