MCP server settings

Connection entries for MCP servers, written for Claude Code, Codex, Cursor and OpenCode. Each names the package it starts and the environment variables it reads, so nothing is guessed at setup.

12 shown here, from 7,252 MCP server settings in the library release of October 9, 2026.

What to watch for

  • A server that reads a key needs it in the environment, never in the settings file.
  • Pin the package version so the server your agent tested is the one it starts.
  • Each harness reads its own settings file in its own place.
