Drop the heidi server block, your instance's /mcp URL plus Authorization header, into ~/.cursor/mcp.json. Cursor reloads MCP servers on save, no restart needed.
Cursor's agent then has your company's memory next to your code: why the service is split, which customers a change affects, what was promised when.
The config block is at falkster.ai/developers/mcp, alongside Windsurf and Codex.
