| Anthropic Connectors (hosted) | Community MCP Servers (self-hosted) | |
|---|---|---|
| What | Remote servers hosted by Anthropic | Open source servers you run locally |
| Setup | Toggle on in Settings > Connectors | Add config JSON or use claude mcp add CLI |
| Install | Nothing to install | Requires Node.js, Python, or similar |
| Auth | Handled by Anthropic | You manage API keys and tokens |
| Examples below | ClinicalTrials.gov, bioRxiv, PubMed, Seqera | cBioPortal (TCGA), Hugging Face |
Remote MCP servers hosted by Anthropic. Enable with a toggle — no install, no config files. Anthropic manages the infrastructure.
Setup (same for all connectors): Claude Desktop > Settings > Connectors > find the connector > click Connect
Auth note: ClinicalTrials.gov, bioRxiv, and PubMed require no account or API key. Seqera requires you to authenticate with a free Seqera Platform account (cloud.seqera.io — free Cloud Basic tier, no credit card) during the connector setup flow. No env vars or API tokens to manage — the connector handles auth after you sign in.

Open source servers you install and run locally. Configure via claude_desktop_config.json or claude mcp add CLI. The server process runs on your machine (or connects to a remote endpoint).
Query cancer genomics data from cBioPortal — the open-access platform hosting all 33 TCGA cancer types plus 200+ additional studies. Search mutations, gene expression, copy number, clinical data, and molecular profiles. No authentication required for the public portal.
Why cBioPortal for TCGA? Research hospitals access TCGA data two ways: ~50% query the public databases, ~50% use on-premise snapshots loaded into local cBioPortal instances. This server supports both — point it at the public portal or your hospital's instance via
CBIOPORTAL_BASE_URL.
Cost: Free. The public cBioPortal API has no authentication, no rate limits, and no usage fees. Local instances require your own infrastructure.
Claude Code CLI:
git clone https://github.com/pickleton89/cbioportal-mcp.git
cd cbioportal-mcp
uv syncThen add to Claude Code:
claude mcp add cbioportal-mcp -s local \
