Devtools MCP Server

The MCP ecosystem is full of single-purpose tutorials and vendor-locked adapters. There is no well-maintained, multi-tool, framework-agnostic, production-quality MCP package for everyday developer tooling. It runs locally over stdio via the published package.

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

01 · Install Devtools

Claude Code

claude mcp add marin1321-mcp-devtools -- npx -y @oscarmarin/mcp-devtools

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "marin1321-mcp-devtools": {
      "command": "npx",
      "args": [
        "-y",
        "@oscarmarin/mcp-devtools"
      ]
    }
  }
}

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

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

npm package @oscarmarin/mcp-devtools - the @oscarmarin scope differs from the repo owner (marin1321); confirm it's the project's official package

registry namespace io.github.marin1321 is GitHub-verified and matches the repo owner
