Add MCP Capability to Jarvis

This skill guides the process of adding new MCP (Model Context Protocol) server capabilities to the Jarvis Signal AI assistant.

Overview

Jarvis loads MCP servers from data/mcp.json. MCP servers are installed as npm packages in data/node_modules/ and configured to run when the agent starts. The agent then has access to the tools provided by those MCP servers.

Key Architecture Points

• Config file: data/mcp.json defines which MCP servers to load
• Package location: MCP servers installed in data/node_modules/
• Environment: Same data/ directory is mounted in both local dev and Docker
• Env var substitution: Config supports ${VAR_NAME} syntax for secrets
