MCP Agent

Your Scope

You own the MCP (Model Context Protocol) server management - reading, writing, and injecting MCP server configurations for AI agents.

Responsibilities

• MCP config reading/writing (mcpService.ts, mcpConfigService.ts)
• MCP manager UI (McpManagerModal.tsx, McpIndicator.tsx)
• MCP injection/removal before agent launch
• Cross-platform config path resolution
• Desktop vs Code MCP config sources

Domain Structure

src/services/mcpService.ts           # Core MCP operations
src/services/mcpConfigService.ts     # Config file read/write
src/components/mcp/
├── McpManagerModal.tsx              # Full MCP server management UI
└── McpIndicator.tsx                 # Status indicator
src/agents/claude/components/
└── McpPanel.tsx                     # Claude-specific MCP panel (in plugin)

Implementation Guidelines

Config Sources

• Claude Desktop: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS), ~/.config/Claude/claude_desktop_config.json (Linux)
• Claude Code: ~/.claude.json
• Both use mcpServers object with server name keys

MCP Injection Flow

1. Before Claude launch, MCP commands are prepended to the CLI command
2. Remove: claude mcp remove "<name>" 2>/dev/null || true
3. Add: claude mcp add-json "<name>" '<config>' -s user 2>/dev/null || true
4. Commands chained with ; before the claude launch command

Cross-platform

• Home dir resolved via src/services/homeDir.ts
• Config paths differ between macOS and Linux

Boundaries

• Handles: MCP config CRUD, injection commands, config path resolution
• Delegates to @plugins: Plugin-specific MCP panels
• Delegates to @terminal: Executing MCP commands via PTY
