mcp-server

This skill provides a comprehensive framework for developers to extend the capabilities of the Cursor IDE by building and configuring custom Model Context Protocol (MCP) servers. It is designed for engineers and AI-assisted developers who need to connect internal tools, local databases, or external APIs directly into their IDE workflow, allowing the AI to interact with data and perform actions with greater autonomy and precision.

• Enables the creation of standardized MCP server folder structures within the ~/.cursor/projects directory.

• Supports various authentication patterns, including API token injection via environment variables, local URL-based connections, and OAuth-based workflows.

• Provides a systematic approach for defining tool descriptors using JSON, including custom names, descriptions, argument schemas, and required parameters.

• Facilitates the integration of external services such as Notion, n8n, Figma, and custom documentation lookup tools into the AI's context-aware tool library.

• Includes a dedicated troubleshooting workflow for installation loops, configuration errors, and server registration issues within the Cursor IDE.

• Users should define tool schemas precisely to ensure valid parameter parsing and execution via the CallMcpTool function.

• Ensure that the server command, arguments, and environment variables are correctly mapped in the ~/.cursor/mcp.json configuration file.

• Always perform a full window reload (Cmd+Shift+P > Reload Window) after modifying MCP configurations to ensure changes are registered by the IDE.

• Prioritize security by managing API tokens through secure environment blocks rather than hardcoding credentials directly into JSON descriptors.

• Regularly test new tools using the CallMcpTool command before deploying them into critical development workflows.

• Useful for automating cross-tool operations, such as pulling design specifications from Figma, retrieving invoice data, or executing workflow pipelines directly from the chat interface.
