Can I run Pinecone MCP and Weaviate MCP side by side in the same Claude client?
Yes. Claude Desktop, Cursor, and Claude Code all accept multiple MCP servers in the same config file. Each runs in its own process and exposes a distinct tool namespace, so there are no naming collisions. Memory usage is additive; budget roughly 40-80 MB per server.

Is Pinecone MCP or Weaviate MCP more production-ready?
Pinecone MCP is maintained by Pinecone, which tends to mean faster fixes. Weaviate MCP is backed by Weaviate. For critical workloads, pick the vendor-backed option or pin a specific version.
What authentication does each server need?
Pinecone MCP authenticates with API key. Weaviate MCP uses API key. Store secrets in a password manager or your shell's keychain and inject them via environment variables; never commit them to the MCP config file, which is often synced across machines.
Which one should I pick first if I am just starting with MCP?
Start with whichever backend you already pay for or use daily. If you do not use either yet, Weaviate MCP is fully OSS, so there is no signup friction. You can always add the second one later without disrupting the first.
