Add the Weaviate MCP server to Windsurf

Config last verified Jun 1, 2026

The exact config to run Weaviate in Windsurf — paste it in, restart, and the tools load.

Prerequisites

  • Windsurf installed.
  • MCP_SERVER_ENABLED — Set to true on the Weaviate instance to enable the built-in MCP server at /v1/mcp. Required (server-side).

Setup

1. Open ~/.codeium/windsurf/mcp_config.json

On Windows the file lives at %USERPROFILE%\.codeium\windsurf\mcp_config.json.

2. Add this configuration

Add to ~/.codeium/windsurf/mcp_config.json

~/.codeium/windsurf/mcp_config.json
json
{
  "mcpServers": {
    "weaviate": {
      "serverUrl": "http://localhost:8080/v1/mcp"
    }
  }
}

Heads up

  • Windsurf uses `serverUrl` for remote servers.

3. Restart Windsurf and confirm the Weaviate tools load.

Gotchas

  • Windsurf uses `serverUrl` for remote servers.

Windsurf's Cascade reads MCP servers from an "mcpServers" object in ~/.codeium/windsurf/mcp_config.json. Unlike most clients, remote servers are configured with the "serverUrl" field rather than "url", so a config that uses "url" silently fails to connect. Native remote transport is supported without an OAuth flow.
