### Description (declared)

# IGVF Catalog MCP Server

An MCP (Model Context Protocol) server providing LLM-friendly access to the IGVF Catalog genomics knowledge graph.

## Features

- **Smart Entity Lookup**: Auto-detects entity type from ID patterns (genes, variants, proteins, etc.)
- **Genomic Region Search**: Flexible region format parsing with multi-entity queries
- **Relationship Discovery**: Find eQTLs, GWAS associations, protein interactions, and more
- **ID Translation**: Convert between variant ID formats (rsID, SPDI, HGVS, etc.)
- **Data Source Discovery**: Dynamically discover available datasets and filters

## Installation

The server is published on PyPI as [`igvf-catalog-mcp`](https://pypi.org/project/igvf-catalog-mcp/). Run it without installing anything using [uv](https://docs.astral.sh/uv/):

```bash
uvx igvf-catalog-mcp
```

or install it with pip and run the `igvf-catalog-mcp` command:

```bash
pip install igvf-catalog-mcp
igvf-catalog-mcp
```

To use it from an MCP client such as Claude Desktop or Claude Code, register it as a stdio server:

```json
{
  "mcpServers": {
    "igvf-catalog": {
      "command": "uvx",
      "args": ["igvf-catalog-mcp"]
    }
  }
}
```

## Usage

Configure the API URL (optional):

```bash
export IGVF_CATALOG_API_URL=https://api.catalogkg.igvf.org  # default
# or for development:
export IGVF_CATALOG_API_URL=https://catalog-api-dev.demo.igvf.org
export IGVF_CATALOG_API_URL=http://localhost:2023
```

`/api` is appended to the URL if it is not already there.

## Tools

### 1. `igvf_catalog_get_entity`
Look up any entity by ID with automatic type detection.

```json
{"id": "BRCA1"}
{"id": "rs12345"}
{"id": "ENSG00000141510"}
{"id": "lupus", "hint": "disease", "limit": 50, "page": 1}
```

### 2. `igvf_catalog_search_region`
Find all entities within a genomic region.

```json
{"region": "chr17:41000000-42000000"}
```

### 3. `igvf_catalog_find_associations`
Discover relationships between entities.

```json
{"entity_id": "TP53", "relationship": "regu…
