The Model Context Protocol (MCP) is a standard that allows coding assistants and other AI tools to interact with platforms like Pinecone. The Pinecone Developer MCP Server allows you to connect these tools with Pinecone projects and documentation.
Once connected, AI tools can:
- Search Pinecone documentation to answer questions accurately.
- Help you configure indexes based on your application's needs.
- Generate code informed by your index configuration and data, as well as Pinecone documentation and examples.
- Upsert and search for data in indexes, allowing you to test queries and evaluate results within your dev environment.
See the docs for more detailed information.
This MCP server is focused on improving the experience of developers working with Pinecone as part of their technology stack. It is intended for use with coding assistants. Pinecone also offers the Assistant MCP, which is designed to provide AI assistants with relevant context sourced from your knowledge base.
To configure the MCP server to access your Pinecone project, you will need to generate an API key using the console. Without an API key, your AI tool will still be able to search documentation. However, it will not be able to manage or query your indexes.
The MCP server requires Node.js. Ensure that node and npx are available in your PATH.
Next, you will need to configure your AI assistant to use the MCP server.
To add the Pinecone MCP server to a project, create a .cursor/mcp.json file in the project root (if it doesn't already exist) and add the following configuration:
{
"mcpServers": {
"pinecone": {
"command": "npx",
"args": [
"-y", "@pinecone-database/mcp"
],
"env": {
"PINECONE_API_KEY": "<your pinecone api key>"
}
}
}
}
You can check the status of the server in Cursor Settings > MCP.
To enable the server globally, add the configuration to the .cursor/mcp.json in your home directory instead.
It is recommended to use rules to instruct Cursor on proper usage of the MCP server. Check out the docs for some suggestions.
Use Claude desktop to locate the claude_desktop_config.json file by navigating to Settings > Developer > Edit Config. Add the following configuration:
{
"mcpServers": {
"pinecone": {
"command": "npx",
"args": [
"-y", "@pinecone-database/mcp"
],
"env": {
"PINECONE_API_KEY": "<your pinecone api key>"
}
}
}
}
Restart Claude desktop. On the new chat screen, you should see a hammer (MCP) icon appear with the new MCP tools available.
Once configured, your AI tool will automatically make use of the MCP to interact with Pinecone. You may be prompted for permission before a tool can be used. Try asking your AI assistant to set up an example index, upload sample data, or search for you!
Pinecone Developer MCP Server provides the following tools for AI assistants to use:
search-docs: Search the official Pinecone documentation.list-indexes: Lists all Pinecone indexes.describe-index: Describes the configuration of an index.describe-index-stats: Provides statistics about the data in the index, including the number of records and available namespaces.create-index-for-model: Creates a new index that uses an integrated inference model to embed text as vectors.upsert-records: Inserts or updates records in an index with integrated inference.search-records: Searches for records in an index based on a text query, using integrated inference for embedding. Has options for metadata filtering and reranking.cascading-search: Searches for records across multiple indexes, deduplicating and reranking the results.rerank-documents: Reranks a collection of records or text documents using a specialized reranking model.
Only indexes with integrated inference are supported. Assistants, indexes without integrated inference, standalone embeddings, and vector search are not supported.
