cursor-mcp
MCP servers expose tools to the agent. Configure them on AgentOptions.mcpServers (or SendOptions.mcpServers for per-run override) as Record<string, McpServerConfig> — the key is the server name.
Transports
- [[references/stdio]] —
command, args, env, cwd
- [[references/http]] —
url, headers, auth
- [[references/sse]] —
url with SSE transport
Configuration patterns
- [[references/inline-config]] —
mcpServers on Agent.create
- [[references/per-run-override]] —
mcpServers on agent.send (replaces, doesn't merge)
- [[references/file-config]] —
.cursor/mcp.json and settingSources
- [[references/persistence]] — inline servers are not persisted across
Agent.resume
Auth
- [[references/oauth]] —
auth.CLIENT_ID / CLIENT_SECRET / scopes for HTTP/SSE
