ChemCP vs Pdbe

A side-by-side look at the ChemCP and Pdbe 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 Pdbe for biology & bioinformatics as a local process. You can also run both side by side in one mcpServers block.

Tools & capabilities

ChemCP tools

No tool names declared yet. Check the project README from the listing page.

Pdbe tools 3

  • get_summaryPDBe (Protein Data Bank in Europe, EBI): get a PDB entry summary — title, experimental method, release date, source organism, and entity counts (polypeptide/ligand/water/...). Keyless. The EBI counterpart to RCSB PDB. Pass a 4-char PDB id like "1cbs".
  • get_moleculesPDBe (EBI): list the molecules/entities in a PDB structure — proteins, nucleic acids, and ligands, each with entity_id, molecule_type, name, and chain length. Keyless. Pass a 4-char PDB id like "1cbs".
  • uniprot_mappingsPDBe (EBI): SIFTS cross-database mapping of a PDB structure to UniProt — for each UniProt accession, the matching chains and residue range. Curated cross-database mappings unique to EBI. Keyless. Pass a 4-char PDB id like "1cbs".

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. Pdbe belongs to Biology & Bioinformatics and uses a local stdio subprocess. Pick ChemCP for biology & bioinformatics work and Pdbe 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. Pdbe 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 pdbe 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. Pdbe has 51/100 (Good) with 2 views, 0 installs and 0 GitHub stars.
