Summary

Enables Discord server admins to configure MCP (Model Context Protocol) servers for their communities. When users chat about a Discord server on Answer Overflow, the AI will have access to tools from that server's configured MCP servers.

Changes

• Add MCPServerConfig schema to server preferences (mcpServers field)
• Create MCP client wrapper utilities (packages/ai/src/tools/mcp-tools.ts):
  • createMCPToolsFromServers() - Connects to multiple HTTP MCP servers and aggregates their tools
  • Tools are prefixed with server name to avoid collisions (e.g., my_server__tool_name)
  • 10 second timeout, graceful error handling
• Integrate MCP tools into streamChat() - fetches MCP servers from server preferences when a server context is provided
• Add analytics events for server MCP config management

How It Works

1. Server admin configures MCP servers in their server preferences (name + URL pairs)
2. When a user starts a chat with that server's context, streamChat() fetches the server's MCP config
3. MCP tools from all configured servers are loaded and made available to the AI agent
4. Tool names are prefixed to avoid collisions between servers

Next Steps

• Create server admin UI for managing MCP servers (in dashboard/server settings)
• Add server preference mutations for MCP management (admin-only)

Testing

To test manually:

1. Add MCP servers to a server's preferences via Convex dashboard
2. Start a chat with that server's context
3. Verify MCP tools appear and work in the chat
