About sirmews/mcp-pinecone
mcp-pinecone is a Model Context Protocol (MCP) server that enables reading from and writing to a Pinecone vector index. It provides a set of tools for semantic search, document retrieval, index statistics, and document processing with automatic chunking and embedding generation via Pinecone's inference API. Designed primarily for integration with Claude Desktop, it supports rudimentary Retrieval-Augmented Generation (RAG) workflows. The server is open source, installable via Smithery or uv, and offers tools like semantic-search, read-document, list-documents, pinecone-stats, and process-document. Note: this repository has been archived and is no longer actively maintained.

FAQ
How do I install mcp-pinecone?
You can install it automatically via Smithery using: npx -y @smithery/cli install mcp-pinecone --client claude. Alternatively, use uv: uvx install mcp-pinecone or uv pip install mcp-pinecone, then configure the Claude Desktop config file.
What tools does mcp-pinecone provide?
It provides five tools: semantic-search, read-document, list-documents, pinecone-stats, and process-document. These allow searching, reading, listing, retrieving stats, and processing documents into the Pinecone index.
Is this server still actively maintained?
No. The repository was archived by the owner on November 10, 2025, and is now read-only. It is no longer actively maintained or updated.
