Which MCP Server Should You Choose?
M
Choose Mychem when:
You need dedicated capabilities in the Developer Tools domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
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 Providence Tools (3)
datasets
Search the Providence 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).
Mychem is categorized under Developer Tools and uses a remote streaming HTTP/SSE transport. In contrast, Data Providence belongs to Developer Tools using remote streaming HTTP/SSE transport. Select Mychem when you need capabilities focused on developer tools and Data Providence when you require tools for developer tools.

metadata
Get a Providence Open Data dataset's schema + metadata (columns, types, row count, category, last-updated) by resource_id, e.g. "vank-fyx9".
