Question:

Session 60.2: How to enable external access to Cloud MCP for Claude Cowork?

Task: Not specified

🎯 Decision Made

Chosen:

Add JwtOrApiKeyGuard to tool-calling endpoints

Options Considered:

• No alternatives documented

💭 Reasoning

API Key authentication was already implemented (ProjectApiKeyGuard, JwtOrApiKeyGuard) in Session 59.1 but not wired to endpoints. Changed mcp-gateway.controller.ts: (1) Removed class-level @UseGuards(JwtAuthGuard), (2) Added @UseGuards(JwtOrApiKeyGuard) to tools, tools/call, preflight, usage endpoints, (3) Kept @UseGuards(JwtAuthGuard) on project management endpoints (create/list/update require login). This allows external projects to authenticate with X-MCP-API-Key + X-MCP-Project-Id headers.
