MCP Tool Review Pattern: When auditing tickets that add "MCP tools", must verify TWO layers: 1. Rails HTTP API endpoint in app/controllers/api/v1/mcp_controller.rb 2. Actual MCP tool definition in mcp-bridge/src/tools/index.ts Example failure: Ticket #78 added the Rails API endpoint for get_status but did NOT add the tool definition to mcp-bridge/src/tools/index.ts. The MCP tool calls the Rails API via api.post('/mcp/execute', { tool: 'tool_name', params: {...} }).
