# Open Targets — AI Connector Open Targets publishes 4 MCP tools to Claude. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/data-analytics/open-targets/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Data & Analytics](https://node8.ai/ai-connectors/data-analytics/) # Open Targets Target-disease association data for drug discovery research Listed in Claude · 4 published tools · Verified partner [Claude connector docs](https://github.com/opentargets/open-targets-platform-mcp) [opentargets.org](https://www.opentargets.org) Overview ## What Open Targets does The Open Targets Platform integrates public datasets to build and score associations between candidate drug targets and diseases, with annotation covering targets, diseases and phenotypes, drugs, variants, GWAS and molecular QTL studies, and the relationships between them. This connector wraps the platform's GraphQL API together with instructions on how to read what comes back. The data is public, and the endpoint answered a tool listing request without credentials, so no account is involved in reaching it. It carries the partner tier. ### Who it is for Computational biologists and target discovery researchers. ### Tool surface Five tools answered against four claimed, and the shape is a GraphQL harness rather than one tool per entity: two schema calls, get\_open\_targets\_graphql\_schema and get\_type\_dependencies, then search\_entities to resolve names to identifiers, then query\_open\_targets\_graphql and its batch variant. The caller composes the GraphQL, which raises the floor on what is needed to use it. Availability ## Where Open Targets is listed Open Targets is listed in the Claude connectors directory only. OpenTargets has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them. The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one. Claude listing ## In the Claude connectors directory Open Targets publishes 4 tools to Claude, a deliberately narrow surface; only 17.2% of the 1,253 Claude-listed connectors expose fewer. The median Claude-listed connector filed under Data & Analytics publishes 12, so this one sits 8 tools below its bucket's median, 163rd of 198. It falls in the 4-6 tools band, which holds 16.2% of the Claude directory. ### Measured against the live endpoint A direct call to the endpoint returned 5 tools, 1 more than the 4 the listing publishes. Probed 2026-08-07. #### Tools the server actually returns - `get_open_targets_graphql_schema` - `get_type_dependencies` - `search_entities` - `query_open_targets_graphql` - `batch_query_open_targets_graphql` Open Targets publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally. Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there. Publisher OpenTargets Verification Verified partner (37.8% of the Claude directory) Filed under Data & Analytics Endpoint `https://mcp.platform.opentargets.org/mcp` Documentation [Publisher setup docs](https://github.com/opentargets/open-targets-platform-mcp) Published tools 4 · 4-6 tools band Depth rank in Data & Analytics 163 of 198 Snapshot August 2026 Open Targets carries partner verification in the Claude directory, which 474 of 1,253 listings do (37.8%). That is a review step past self-publishing, not an Anthropic-built server. In the publisher's words ## How OpenTargets describes it > This MCP provides a purpose-built interface and instructions to access and interpret the data and analyses in the Open Targets Platform. The Open Targets Platform is a comprehensive tool that supports systematic identification and prioritisation of potential therapeutic drug targets, integrating publicly available datasets to build and score target-disease associations. It also integrates relevant annotation information about targets, diseases/phenotypes, drugs, variants, GWAS and molecular QTL studies, and credible sets, as well as their most relevant relationships.
