Find, install, and configure MCP servers. Use proactively for MCP discovery, OAuth setup, env vars, stdio vs SSE transport, or troubleshooting MCP connections.
Examples:
- user: "Add the filesystem MCP server" → read server file, add to mcpServers in opencode.json, verify transport type
- user: "How do I use MCP with GitHub?" → check catalog, install @modelcontextprotocol/server-github, configure OAuth token
- user: "MCP not connecting" → check transport type (stdio/SSE), verify args/command, check env vars are passed
- user: "What MCPs are available?" → run list_mcps.py, show catalog with auth types and install commands
