FORGE MCP Builder Skill

Use this skill when you need to build or extend MCP servers to provide new capabilities to the AgentFlow system.

High-Level Workflow

Phase 1: Research and Planning

• Understand the external system or data source you are integrating.
• Define the necessary tools and resources.
• Choose the appropriate language/SDK (Rust, Python, Node.js).

Phase 2: Implementation

• Implement the core protocol (Tools, Resources, Prompts).
• Follow the official MCP Specification.
• Ensure robust error handling and type safety.

Phase 3: Review and Test

• Verify transport layers (Stdio, HTTP/SSE).
• Test tool execution and resource retrieval.
• Check for protocol compliance.

Phase 4: Integration

• Create evaluations and documentation.
• Add components to the .claude-plugin/plugin.json or .mcp.json.

Documentation Reference

Consult the official SDK documentation for the language you choose. Prioritize security and minimal permission sets when exposing system capabilities via tools.
