MCPX Cursor Integration

MCPX Cursor Integration

Cursor extension that syncs MCPX-managed MCP servers into Cursor's MCP configuration.

Features

• Discover MCP servers installed under the MCPX root (~/.mcp/servers by default).
• Write Cursor MCP configuration JSON to the default data directory, with overrides.
• Support MCPX orchestrator endpoint for single-entry configuration.

Development

pnpm install
pnpm --filter mcpx-cursor-extension dev

Commands

• MCPX: Sync Cursor MCP Servers (mcpxCursor.syncServers) — refresh Cursor MCP configuration from MCPX.
• MCPX: Install Server from Registry (mcpxCursor.installFromRegistry) — install a server listed in the MCPX registry and update Cursor config.
• MCPX (Agent): Search Registry (mcpxCursor.searchRegistry) — returns registry metadata for agent workflows (no UI).
• MCPX (Agent): Install Server by ID (mcpxCursor.installServer) — programmatically install/update a registry server with optional environment overrides.

Configuration Options

• mcpxCursor.mcpRoot – override MCP root directory.
• mcpxCursor.configPath – explicit Cursor MCP config file path.
• mcpxCursor.orchestratorUrl – use orchestrator proxy instead of per-server commands.

Publishing

pnpm --filter mcpx-cursor-extension build
