Fixes the Weaviate MCP server failing to connect because it uses the wrong connection helper: local client code against Weaviate Cloud, or the cloud helper against local Docker. The fix is matching the connection mode to the deployment. Use when the URL scheme and deployment disagree; not for auth errors.
Fixes the SQLite MCP server failing to start with uvx: command not found or spawn uvx ENOENT. The official server is distributed via uvx, which requires the uv package manager. The fix is installing uv first. Use when the client cannot spawn the server at all; not for database errors.

Fixes the Redis MCP server failing to connect to managed Redis (Upstash, Redis Cloud) over plain redis://. Managed endpoints mandate TLS. The fix is using the rediss:// scheme (or REDIS_SSL=true). Use when connecting to any managed Redis; not for local dev instances.
Fixes the Redis MCP server failing with NOAUTH Authentication required when the Redis instance has a password. The server connects without credentials because REDIS_PWD was never set. The fix is setting REDIS_PWD (and REDIS_USERNAME if ACLs are used) in the server env. Use when Redis requires auth and the MCP server d…

Guide Prisma + Neon: pooled URL for the app, direct URL for the CLI: # Prisma + Neon: two connection strings, each with its job ## The trap Agents set a single DATABASE_URL and use it everywhere. Use this when you hit exactly this in Prisma + Neon. Not for different errors or different tools.
Vectle found the following relevant skills: - Qdrant MCP: QDRANT_URL on gRPC port 6334 (use REST port 6333) - Remote Qdrant fails to connect when the URL includes port 6333
Problem outcome: unknown
Public search query: Qdrant MCP: QDRANT_URL on gRPC port 6334 (use REST port 6333)
Problem outcome: unknown
Fixes the Qdrant MCP server failing to connect when QDRANT_URL points at the gRPC port 6334 instead of the REST port 6333. The MCP server talks REST, so the gRPC port never answers correctly. The fix is using port 6333 in QDRANT_URL. Use when the ports are confused; not for auth errors.
Vectle found the following relevant skills: - Remote Qdrant fails to connect when the URL includes port 6333 - Qdrant MCP: connection refused (Qdrant not running or wrong QDRANT_URL)
