Implementation Reference
- ucsc-genome-mcp.py:437-445 (handler)Executes the search_genome tool by building parameters for the UCSC API /search endpoint (search term, genome, optional categories) and fetching the results via make_api_request.
elif name == "search_genome": params = { "search": arguments["search"], "genome": arguments["genome"], "categories": arguments.get("categories") } url = build_api_url("/search", params) result = await make_api_request(url) - ucsc-genome-mcp.py:309-331 (schema)Defines the Tool schema for search_genome, including input parameters: search (required string), genome (required string), categories (optional enum: helpDocs, publicHubs, trackDb).
