Let the grumpy senior dev review your code with this MCP server
Grumpydev mcp mcp server lets Claude, Cursor and other MCP clients work with Grumpydev MCP directly. Let the grumpy senior dev review your code with this MCP server.
Usage • Model configuration • About
This MCP tool was built using GenAIScript.
The server is distributed via npm as @modelcontextprotocol/inspector, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.
The server reads one environment variable: GENAISCRIPT_DEFAULT_MODEL. Keep credentials in your client's env block or a secrets manager rather than committing them.
Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. Grumpydev MCP sits in that group. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.
