Candor vs Uniprot MCP Server
A side-by-side look at the Candor and Uniprot MCP Server MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Candor for biology & bioinformatics work as a local process; choose Uniprot MCP Server for biology & bioinformatics. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Candor when
- You need dedicated capabilities in the Biology & Bioinformatics domain.
- You prefer a local stdio subprocess transport.
Choose Uniprot MCP Server when
- You need dedicated capabilities in the Biology & Bioinformatics domain.
- Its auth model fits you: No auth required.
- You want tools like
uniprot_search_proteins, uniprot_get_entry, uniprot_map_ids.

Uniprot MCP Server tools 6
uniprot_search_proteinsSearch UniProtKB by plain text or a Lucene field query, with the reviewed (Swiss-Prot) filter foregrounded and optional server-side facet counts. Cursor-paginated. The discovery entry point.uniprot_get_entryFetch full curated entries by accession in one batch (up to 20) — function, catalytic activity, disease, variants, isoforms, GO terms, cross-references. Partial-success output; an oversized record returns a section outline.uniprot_map_idsTranslate identifiers across databases via UniProt's async ID-mapping service — gene names, Ensembl, RefSeq, ChEMBL, PDB, GeneID ↔ UniProtKB accessions. Polls within a budget; running jobs return a ticket and completed pages return a continuation.uniprot_get_proteomeFetch a reference proteome by UPID or NCBI taxon ID — protein count, BUSCO completeness, genome assembly inline, plus an opt-in capped page of the proteins.uniprot_get_taxonomyResolve a taxonomy record by NCBI taxon ID or scientific name — name, rank, parent, full lineage, and optionally the immediate children, cursor-paginated.uniprot_get_sequenceFetch the canonical amino-acid sequence (FASTA) for an accession, with length and parsed header — and optionally the isoform sequences. The cheap sequence-only path.

Frequently asked questions
Candor is categorized under Biology & Bioinformatics and uses a local stdio subprocess. Uniprot MCP Server belongs to Biology & Bioinformatics and uses an install path we have not confirmed yet. Pick Candor for biology & bioinformatics work and Uniprot MCP Server 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. Uniprot MCP Server has no confirmed install command yet — follow its own setup instructions.
Candor has no declared pricing — check the project's own site. Uniprot MCP Server is listed as free. Auth: no auth required. 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 candor and uniprot-mcp-server as separate keys in the same mcpServers object, and your assistant will call tools from either one.
