This performs the overall steps of chunking, embedding, and upserting. Note: embeddings are generated via Pinecone's inference API and chunking is done with a token-based chunker. Written by copying a lot from langchain and debugging with Claude. ## Quickstart ### Installing via Smithery To install Pinecone MCP Server for Claude Desktop automatically via [Smithery](https://smithery.ai/server/mcp-pinecone): ```bash npx -y @smithery/cli install mcp-pinecone --client claude ``` ### Install the server Recommend using [uv](https://docs.astral.sh/uv/getting-started/installation/) to install the server locally for Claude. ``` uvx install mcp-pinecone ``` OR ``` uv pip install mcp-pinecone ``` Add your config as described below. #### Claude Desktop On MacOS: `~/Library/Application\ Support/Claude/claude_desktop_config.json` On Windows: `%APPDATA%/Claude/claude_desktop_config.json` Note: You might need to use the direct path to `uv`. Use `which uv` to find the path. __Development/Unpublished Servers Configuration__ ```json "mcpServers": { "mcp-pinecone": { "command": "uv", "args": [ "--directory", "{project_dir}", "run", "mcp-pinecone" ] } } ``` __Published Servers Configuration__ ```json "mcpServers": { "mcp-pinecone": { "command": "uvx", "args": [ "--index-name", "{your-index-name}", "--api-key", "{your-secret-api-key}", "mcp-pinecone" ] } } ``` #### Sign up to Pinecone You can sign up for a Pinecone account [here](https://www.pinecone.io/). #### Get an API key Create a new index in Pinecone, replacing `{your-index-name}` and get an API key from the Pinecone dashboard, replacing `{your-secret-api-key}` in the config. ## Development ### Building and Publishing To prepare the package for distribution: 1. Sync dependencies and update lockfile: ```bash uv sync ``` 2. Build package distributions: ```bash uv build ``` This will create source and wheel distributions in the `dist/` directory. 3. Publish to PyPI: ```bash uv publish ``` Note: You'll need to set PyPI credentials via environment variables or command flags: - Token: `--token` or `UV_PUBLISH_TOKEN` - Or username/password: `--username`/`UV_PUBLISH_USERNAME` and `--password`/`UV_PUBLISH_PASSWORD` ### Debugging Since MCP servers run over stdio, debugging can be challenging. For the best debugging experience, we strongly recommend using the [MCP Inspector](https://github.com/modelcontextprotocol/inspector). You can launch the MCP Inspector via [`npm`](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm) with this command: ```bash npx @modelcontextprotocol/inspector uv --directory {project_dir} run mcp-pinecone ``` Upon launching, the Inspector will display a URL that you can access in your browser to begin debugging. ## License This project is licensed under the MIT License.
