Windsurf reads its MCP servers from mcp_config.json under the mcpServers key. The MCPs icon in the top right of the Cascade panel, or Devin Settings, Cascade, MCP Servers. The documentation for this file now lives under the Devin Desktop product name; the Windsurf docs URL redirects there. Save and reopen the MCP Servers list; Cascade picks it up without restarting the editor.
| Scope | Path |
|---|---|
| macOS, Windows and Linux | ~/.codeium/windsurf/mcp_config.json |
Read this first: mcp_config.json applies to the legacy Cascade agent only. The Devin Local agent, the default for new tabs, takes its servers from the Devin CLI config files, so a correct entry here can still be invisible in a fresh tab. The other hard number is a cap: Cascade reaches at most 100 tools at once, and every enabled server spends from it.
