Link compounds to protein targets, rank bioactivity (IC50/Ki/EC50), and look up drug mechanisms and indications over ChEMBL via MCP. STDIO or Streamable HTTP.
cyanheads/chembl-mcp-server is an MCP server distributed on github, maintained by cyanheads, tracked here since June 2026. It has shipped 6 releases and exposes 8 tools. Tools include chembl_dataframe_describe, chembl_dataframe_drop, chembl_dataframe_query, chembl_get_assay, chembl_get_bioactivities, chembl_get_drug_info, and 2 more. Its composite risk grade is A — an inferred review prompt computed from observed signals, not a verdict.
Since the previous scan on 2026-09-09: 8 tools added and 10 tools removed.
