A Model Context Protocol (MCP) server that provides semantic search over Pinecone vector databases using hybrid search (dense + sparse) with reranking.

## Features

- **Hybrid Search**: Combines dense and sparse embeddings for superior recall
- **Semantic Reranking**: Uses BGE reranker model for improved precision
- **Dynamic Namespace Discovery**: Automatically discovers available namespaces in your Pinecone index
- **Metadata Filtering**: Supports optional metadata filters for refined searches
- **Fast & Optimized**: Lazy initialization, connection pooling, and efficient result merging
- **Production Ready**: Input validation, error handling, and configurable logging

## Installation

In a `uv` managed python project, add to dependencies by:

```bash
uv add pinecone-read-only-mcp
```

Alternatively, for projects using `pip` for dependencies:

```bash
pip install pinecone-read-only-mcp
```

To run the server inside your project:

```bash
uv run pinecone-read-only-mcp --api-key YOUR_PINECONE_API_KEY
```

Or to run it globally in isolated environment:

```bash
uvx pinecone-read-only-mcp --api-key YOUR_PINECONE_API_KEY
```

To install directly from the source:

```bash
git clone https://github.com/iTinkerBell/pinecone-read-only-mcp.git
cd pinecone-read-only-mcp
pip install -e .
```

## Configuration

The server requires a Pinecone API key and supports the following configuration options:
