It is an MCP server that provides intelligence on negative results in drug discovery across multiple modalities. It serves researchers seeking failed compounds, terminated trials, inactive screens, and other non-positive outcomes.
Interact by asking natural language questions about negative results in drug discovery, such as "What's failed against EGFR?" or "Which kinase inhibitors were inactive in ChEMBL?" The README does not specify installation or configuration steps.
You can query failed compounds, terminated clinical trials, inactive screens, and failed CRISPR knockouts, among other non-positive outcomes.
Every response includes a citation to its source, providing transparency for the negative results returned.
Supported modalities include small molecule, CRISPR, antibody, peptide, PROTAC, clinical trial, and more.
