Opentargets vs Hindsight
A side-by-side look at the Opentargets and Hindsight MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Opentargets for biology & bioinformatics work as a local process; choose Hindsight for knowledge & memory as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Opentargets when
- You need dedicated capabilities in the Biology & Bioinformatics domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: No auth required.
- You have the keys it needs:
MCP_TRANSPORT, FASTMCP_SERVER_HOST, FASTMCP_SERVER_PORT, OPEN_TARGETS_API_URL, OPEN_TARGETS_RATE_LIMIT_RPS, OPEN_TARGETS_RATE_LIMIT_BURST, OPEN_TARGETS_RATE_LIMIT_ENABLED. - You want tools like
get_target_alternative_genes, get_target_associated_diseases, get_target_chemical_probes.
Choose Hindsight when
- You need dedicated capabilities in the Knowledge & Memory domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: API key required.
- You have the keys it needs:
HINDSIGHT_API_LLM_API_KEY, HINDSIGHT_API_LLM_PROVIDER, HINDSIGHT_DB_PASSWORD.

Frequently asked questions
Opentargets is categorized under Biology & Bioinformatics and uses a local stdio subprocess. Hindsight belongs to Knowledge & Memory and uses a local stdio subprocess. Pick Opentargets for biology & bioinformatics work and Hindsight for knowledge & memory.
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.
Opentargets is listed as free. Auth: no auth required. Hindsight is listed as free. Auth: api key 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 opentargets and vectorize-io-hindsight as separate keys in the same mcpServers object, and your assistant will call tools from either one.
On AllMCPs, Opentargets has a quality signal of 63/100 (Good) with 4 views, 0 installs and 19 GitHub stars. Hindsight has 57/100 (Good) with 14 views, 0 installs and 53,003 GitHub stars.
