Auto-Discovery Implementation

Replicate's MCP server can now be discovered automatically through the official MCP Registry, an official metadata repository backed by Anthropic, GitHub, and Microsoft. The implementation follows standard specifications by exposing a /.well-known/mcp/server.json endpoint that publishes comprehensive metadata about the MCP server.

How It Works

The MCP Registry doesn't host code directly—it serves as a centralized metadata repository that describes where to find servers and how to install them. When you publish a server.json file at the well-known endpoint, the Registry can discover your server automatically, and MCP clients use the Registry to find and install servers without manual configuration.

Client Integration

Several MCP clients now have built-in discovery capabilities:

• VS Code: Best Registry integration available. Enable chat.mcp.gallery.enabled in settings, then search @mcp in the Extensions view to browse and install servers.
• Claude Desktop: Features a curated extensions directory accessible via Settings > Extensions > Browse extensions.
• Other clients (ChatGPT, Cursor, LM Studio): Currently require manual configuration with server URLs or config file edits.

Configuration Options

The published metadata exposes a --tools flag that allows developers to choose between standard tools (all) or code mode (code) when installing the Replicate MCP server, providing flexibility in how the integration is configured.
