⚡ Bolt: [Batch FeathersJS MCP OAuth Token Fetches]

[Donach]

💡 What: Implemented a batched token retrieval method getTokensForServers in the UserMCPOAuthTokenRepository and refactored the injectPerUserOAuthTokens hook to pre-fetch all needed tokens using Drizzle's inArray prior to mapping.

🎯 Why: Previously, when fetching a list of MCP servers (like in a paginated find endpoint), the injectToken map function would execute an individual database lookup for each MCP server to inject its corresponding OAuth token. This caused an O(N) database query explosion (N+1 query issue).

📊 Impact: Severely reduces database round-trips from O(N) to O(1) for lists of MCP servers, lowering query latency, decreasing API response times, and reducing load on the database connection pool.

🔬 Measurement: Review database query logs or use performance monitoring when hitting the mcp-servers find endpoint. The number of SELECT queries for user_mcp_oauth_tokens will remain at exactly one query, regardless of how many MCP servers are returned in the response.
