Material Project MCP Server

A Model Context Protocol server that provides materials validation capabilities. This server enables LLMs to verify invented materials are novel and valid or not. We currently support cathode battery materials.

CAUTION

This server can access local/internal IP addresses and may represent a security risk. Exercise caution when using this MCP server to ensure this does not expose any sensitive data.

Available Tools

search_material

Searches and returns relevant battery materials from the database.

Parameters:

  • formula (string, required): Formula query for battery materials (e.g., "LiCoO2")

  • n (integer, optional): Number of results to return (default: 5, min: 1, max: 100)

verify_input_material

Validates whether a material exists in the database.

Parameters:

  • original_material (string, required): Material formula to validate (e.g., "LiFePO4")

battery_material_validation

Parses and validates battery materials from a query, comparing them against a reference material.

Parameters:

  • original_material (string, required): Reference battery material (e.g., "LiCoO2")

  • query (string, required): Comma-separated list of proposed materials (e.g., "Li2B4O7, Li1.06Ti2O4")

Installation

This MCP server requires API key from materials project, you can get api key and use it with env variable MP_API_KEY

export MP_API_KEY=

Using uv (recommended)

When using uv no specific installation is needed. We will use uvx to directly run battery-mcp.

Using PIP

Alternatively you can install battery-mcp via pip:

pip install battery-mcp

After installation, you can run it as a script using:

python -m battery_mcp

Running with streamable-http

You can also deploy mcp as http server with streamable-http transport protocol

python -m battery_mcp --transport http --http-host 0.0.0.0 --http-port 8080

or using uvx

uvx battery-mcp --transport http --http-host 0.0.0.0 --http-port 8080

Configuration

Configure for Claude.app

Add to your Claude settings:

{
  "mcpServers": {
    "fetch": {
      "command": "uvx",
      "args": ["battery-mcp"]
    }
  }
}
{
  "mcpServers": {
    "fetch": {
      "command": "python",
      "args": ["-m", "battery-mcp"]
    }
  }
}
