Feature & Specification Comparison
Tools & Capabilities Breakdown
Mychem Tools (3)
query
Search MyChem.info for drugs / chemical compounds. Accepts a plain drug name ("aspirin"), an InChIKey, or a fielded query (e.g. "chembl.pref_name:aspirin", "drugbank.name:Acetylsalicylic acid"). Returns aggregated hits with cross-references to ChEMBL, DrugBank, PubChem, ChEBI, DrugCentral, etc. Use…
chem
Fetch the full aggregated annotation for a single chemical / drug by id. The id is typically an InChIKey (e.g. "BSYNRYMUTXBXSQ-UHFFFAOYSA-N"), but a DrugBank id, ChEMBL id, or other source id also works. Returns merged annotations from ChEMBL, DrugBank, PubChem, ChEBI, DrugCentral, etc., including…
metadata
Returns MyChem.info build metadata: total indexed compound count, available annotation sources (ChEMBL, DrugBank, PubChem, ChEBI, DrugCentral, FDA NDC), and their current release versions.
Data Norfolk Tools (3)
datasets
Search the Norfolk Open Data catalog of open datasets by keyword. Returns each dataset's resource_id, name, description, category and update date — pass the resource_id to query/metadata.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
