Model Context Protocol server that lets Claude Desktop (or any MCP client) read from and write to a Pinecone index (basic RAG workflow).
https://github.com/sirmews/mcp-pineconeStop copying and pasting context into Claude Desktop. If you're already using Pinecone for your vector searches, this MCP server connects your existing vector database directly to Claude Desktop, turning your AI assistant into a knowledge-powered research tool.
You know the routine: find relevant documents in your vector database, copy the results, paste them into Claude, ask your question, repeat. The mcp-pinecone server eliminates that workflow entirely by giving Claude Desktop native access to your Pinecone index.
Ask Claude to search your documentation, analyze customer feedback patterns, or find similar code examples - and it'll query your vector database directly, retrieve the relevant context, and provide informed answers without you ever leaving the conversation.
Semantic Search: Claude can search your Pinecone index using natural language queries, automatically handling the embedding generation and similarity matching.
Document Processing: Drop documents into your workflow and Claude will chunk them, generate embeddings via Pinecone's inference API, and upsert them into your index - all in one step.
Knowledge Base Integration: Whether it's your company's documentation, research papers, or code repositories, Claude can now access and reason over your existing vector-stored knowledge.
RAG Without the Overhead: Get retrieval-augmented generation working immediately without building custom pipelines or managing embedding models.
Developer Documentation: Connect your API docs, internal wikis, and code examples. Ask Claude "How do we handle authentication in our payment service?" and get answers based on your actual codebase.
Customer Support: Index your support tickets and knowledge base. Claude can find similar issues, suggest solutions, and even draft responses based on historical patterns.
Research and Analysis: Store research papers, market reports, or technical specifications. Claude becomes your research assistant, pulling relevant information and synthesizing insights across documents.
Code Discovery: Index your repositories and let Claude help you find similar implementations, identify patterns, or locate specific functionality across your codebase.
Setup takes minutes, not hours. Install via uvx, add your Pinecone credentials to Claude Desktop's config, and you're running. The server handles all the MCP protocol details - you just get five new tools in Claude Desktop:
semantic-search for finding relevant documentsprocess-document for adding new contentread-document and list-documents for content managementpinecone-stats for index monitoringYour existing Pinecone indexes work as-is. No migrations, no data transformations, no architectural changes to your current setup.
Vector databases are only as useful as your ability to access them when you need answers. By connecting Pinecone directly to Claude Desktop, you're not just adding another tool - you're creating a knowledge-aware AI assistant that can reason over your actual data.
The server uses Pinecone's inference API for embeddings and includes smart chunking logic (borrowed and refined from LangChain). It's production-ready code that handles the complexity of RAG workflows while keeping the interface simple.
