Tool List
search_clinical_evidence: A MCP tool for querying clinical evidence data that returns formatted reports.
Input Schema
The tool accepts the following optional parameters:
disease_name (str): Filter by disease (e.g., "Lung Non-small Cell Carcinoma").therapy_name (str): Filter by therapy or drug (e.g., "Cetuximab").molecular_profile_name (str): Filter by gene or variant (e.g., "EGFR L858R").phenotype_name (str): Filter by phenotype (e.g., "Chest Pain").evidence_type (str): Filter by evidence type (e.g., "PREDICTIVE", "DIAGNOSTIC").evidence_direction (str): Filter by evidence direction (e.g., "SUPPORTS").filter_strong_evidence (bool): If True, only includes evidence with a rating > 3 (max 5).
Output
The tool returns a formatted string with four sections:
- Summary Statistics:
- Total evidence items
- Average evidence rating
- Top 3 diseases, genes, variants, therapies, and phenotypes (with counts)
- Top 10 Evidence Entries:
- Lists the highest-rated evidence items with details like disease, phenotype, gene/variant, therapy, description, type, direction, and rating.
- Sources & Citations:
- Citations and URLs for the sources of the top 10 evidence entries.
- Disclaimer:
- A note stating the tool is for research purposes only, not medical advice.
Sample Usage
- "Find predictive evidence for colorectal cancer therapies involving KRAS mutations."
- "Are there studies on Imatinib for leukemia?"
- "What therapies are linked to pancreatic cancer evidence?"
