Pinecone MCP: Documentation
Updated:
Connection
npx @pinecone-database/mcp (stdio) with a PINECONE_API_KEY env var — get a key from the Pinecone console after signing up. There's no remote endpoint; the server always runs locally alongside the MCP client.
Tools
9 tools: list-indexes, describe-index, describe-index-stats — an overview of existing indexes; create-index-for-model — create an index for a specific embedding model; upsert-records — load records; search-records, cascading-search — similarity search across one or multiple indexes; rerank-documents — re-sort results by relevance; search-docs — search Pinecone's own documentation.
Agent flow
"Create an index for the knowledge base and upsert these articles", "find similar articles and pick the most relevant one", "show me stats for the products index", "how do I set up metadata filtering in Pinecone?" — search-docs answers that one.
Pricing
The MCP server is free, open source. Pinecone itself is freemium: a free Starter plan with a vector limit exists, with paid plans billed by data volume and query traffic.
