ITIS MCP Server

A Model Context Protocol (MCP) server for interacting with the ITIS (Integrated Taxonomic Information System) database via their SOLR API.

Overview

This MCP server provides access to the ITIS database, which contains taxonomic information for hundreds of thousands of species. It uses the ITIS SOLR API to perform searches and retrieve taxonomic data.

Features

• Search by Scientific Name: Find organisms by their scientific names
• Search by TSN: Look up organisms by their Taxonomic Serial Number
• Search by Kingdom: Find organisms within specific kingdoms
• Search by Taxonomic Rank: Search for organisms of specific ranks
• Autocomplete Search: Get suggestions for partial scientific names
• Hierarchical Data: Retrieve complete taxonomic hierarchies
• General SOLR Search: Perform flexible searches with custom SOLR queries
• Statistics: Get database statistics

Installation

1. Clone or download this repository
2. Install dependencies:

   npm install
   

3. Build the project:

   npm run build
   

Usage

As an MCP Server

The server communicates via stdin/stdout and can be used with MCP-compatible clients.

To run the server:

npm start

For development:

npm run dev

MCP Client Configuration

After building the project, add this configuration to your MCP client:

    "itis": {
      "command": "npx",
      "args": ["-y", "path/to/itis-mcp"]
    }
  }
}

Cursor/Other MCP Clients:

Example Queries

Here are some example queries you can use:

Search for Humans

{
  "tool": "search_by_scientific_name",
  "arguments": {
    "name": "Homo sapiens"
  }
}

Search for Plants

{
  "tool": "search_by_kingdom",
  "arguments": {
    "kingdom": "Plantae",
    "rows": 5
  }
}

Autocomplete for Oak Trees

{
  "tool": "autocomplete_search",
  "arguments": {
    "partialName": "Quercus"
  }
}

Custom SOLR Query

{
  "tool": "search_itis",
  "arguments": {
    "query": "nameWInd:*tiger* AND kingdom:Animalia",
    "rows": 10,
    "sort": "nameWInd asc"
  }
}

ITIS Database Fields

The ITIS database contains many fields. Here are the most commonly used ones:

• tsn: Taxonomic Serial Number (unique identifier)
• nameWInd: Scientific name with indicators
• kingdom: Kingdom name
• phylum: Phylum name
• class: Class name
• order: Order name
• family: Family name
• genus: Genus name
• species: Species name
• author: Author citation
• rank: Taxonomic rank
• usage: Usage status (valid, invalid, etc.)
• credibilityRating: Data quality rating
• phyloSort: Phylogenetic sort order

SOLR Query Examples

The ITIS SOLR API supports various query types:

• Exact match: nameWInd:"Homo sapiens"
• Wildcard: nameWInd:Homo*
• Range: tsn:[1 TO 1000]
• Boolean: kingdom:Animalia AND rank:Species
• Phrase: nameWInd:"oak tree"

Configuration

The server uses the official ITIS SOLR endpoint: https://services.itis.gov/

No API key is required as the ITIS database is publicly accessible.

Error Handling

The server includes comprehensive error handling:

• Network errors are caught and reported
• Invalid queries return helpful error messages
• Malformed responses are handled gracefully
