PolyOmics MCP Server

MCP server for the PolyOmics dataset. Query physical property data for 100,000+ polymer materials from Claude and other MCP clients.

Available Tools

Tool	Description
get_database_info	Get overview statistics of the database
search_polymers_by_smiles	Search polymers by SMILES fragment
get_polymer_by_id	Get all properties for a polymer by monomer ID
query_polymers_by_property	Filter polymers by property value range
filter_by_polymer_class	Filter by polymer class (PEST, PAMD, etc.)
get_chi_parameter	Get Flory-Huggins χ parameter for a specific solvent
get_chi_parameters_for_polymer	Get χ parameters for all solvents at once

Connecting from Claude Desktop

Add the following to claude_desktop_config.json:

{
  "mcpServers": {
    "polyomics": {
      "type": "sse",
      "url": "https://<your-username>-polyomics-mcp-server.hf.space/mcp/sse",
      "headers": {
        "Authorization": "Bearer <your-hf-token>"
      }
    }
  }
}

Note: Replace <your-username> and <your-hf-token> with your actual values. Generate an HF token at Settings > Access Tokens (read permission is sufficient).
