How do I install the mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `AIDER_MODEL`, `OPENAI_API_BASE`, `OPENAI_API_KEY` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the MCP Server?

Model Context Protocol (MCP) server to execute aider-specific code editing operations

What you get

An .aider.mcp.details.json file is created in the same directory with the process ID and starting datetime. The MCP server provides tools for LLM agents to check if the process is still running, and to check the .aider.chat.history.md for updates.

More MCP options

Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
