ChemCP vs Mychem
A side-by-side look at the ChemCP and Mychem MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose ChemCP for biology & bioinformatics work as a local process; choose Mychem for biology & bioinformatics as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose ChemCP when
- You need dedicated capabilities in the Biology & Bioinformatics domain.
- You prefer a local stdio subprocess transport.
Choose Mychem when
- You need dedicated capabilities in the Biology & Bioinformatics domain.
- You prefer a local stdio subprocess transport.
- You want tools like
query, chem, metadata.

Mychem tools 3
querySearch 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…chemFetch 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…metadataReturns MyChem.info build metadata: total indexed compound count, available annotation sources (ChEMBL, DrugBank, PubChem, ChEBI, DrugCentral, FDA NDC), and their current release versions.
Ready-to-paste client configs
Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.

Frequently asked questions
ChemCP is categorized under Biology & Bioinformatics and uses a local stdio subprocess. Mychem belongs to Biology & Bioinformatics and uses a local stdio subprocess. Pick ChemCP for biology & bioinformatics work and Mychem for biology & bioinformatics.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
ChemCP has no declared pricing — check the project's own site. Mychem has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add chemcp and mychem as separate keys in the same mcpServers object, and your assistant will call tools from either one.
On AllMCPs, ChemCP has a quality signal of 40/100 (Fair) with 1 views, 0 installs and 2 GitHub stars. Mychem has 45/100 (Fair) with 2 views, 0 installs and 0 GitHub stars.
