Add Selvedge to Windsurf

Windsurf’s Cascade agent loads MCP servers from a single JSON config. Add Selvedge there and Cascade gains the log_change / prior_attempts tools.

Before you start

Section titled “Before you start”

pip install selvedge gives you the selvedge CLI (selvedge setup, selvedge blame, and the selvedge prompt helper below):

Terminal window
pip install selvedge

The MCP config below launches the server with uvx instead of a bare selvedge-server, so it starts reliably even when your editor doesn’t share your shell’s PATH — it just needs uv installed. Prefer the global binary? Swap uvx --from selvedge selvedge-server for selvedge-server.

Add the MCP server

Section titled “Add the MCP server”

Add this to ~/.codeium/windsurf/mcp_config.json — or open it from the MCPs icon in the Cascade panel → Configure:

{
  "mcpServers": {
    "selvedge": {
      "command": "uvx",
      "args": ["--from", "selvedge", "selvedge-server"]
    }
  }
}

Tell your agent when to call it

Section titled “Tell your agent when to call it”

Selvedge only captures the why if your agent knows to call it. Install the one-block instruction set into your project’s CLAUDE.md / .cursorrules:

Terminal window
selvedge prompt --install CLAUDE.md

It’s also a copy-paste block on the site: the Selvedge agent prompt block.

Verify

Section titled “Verify”

Back in the Cascade MCPs panel, refresh the server list — selvedge should connect and expose its 8 tools.

If it doesn’t connect

Section titled “If it doesn’t connect”

After editing mcp_config.json, fully quit and reopen Windsurf — closing the window alone doesn’t reload MCP servers. The config calls uvx, so make sure uv is installed (or pip install selvedge and use command: selvedge-server).
