Target & Disease

The Target & Disease MCP is a target and disease profiling tool covering target characterization, disease profiling, and epidemiology evidence retrieval. It helps the AI assistant fetch target and disease details by IDs or names and retrieve epidemiology evidence using natural-language semantic search. Tools included: • target_fetch: Fetch target details in batch by target IDs or target names. • disease_fetch: Fetch disease details in batch by disease IDs or disease names. • epidemiology_search: Retrieve epidemiology evidence snippets using semantic vector search.

• When you have target names or target IDs and need target profile information. • When you have disease names or disease IDs and need disease profiles, standardized names, external identifiers, or references. • When the question involves prevalence, incidence, disease burden, epidemiology studies, or population characteristics. • When you need to resolve target or disease entities before using drug, clinical trial, or translational medicine MCPs. • Not suitable for direct drug asset or clinical trial search; use the Drug & Asset or Clinical Trials MCP instead.

• For target_fetch, provide either target_ids or target; at least one must be present. • For disease_fetch, provide either disease_ids or disease; at least one must be present. • For epidemiology_search, provide a natural-language query and lang, where lang is CN or EN; optionally use top_k to control the number of returned snippets. • Queries should focus on diseases, populations, epidemiology indicators, or study subjects, and avoid overly generic meta-terms.

• target_fetch returns target detail records, including target IDs, display names, related identifiers, and references. • disease_fetch returns disease detail records, including disease IDs, Chinese and English names, MeSH, UMLS, and reference fields. • epidemiology_search returns semantically matched epidemiology evidence snippets, usually including text, source, URL, document type, and reference.

• target_fetch and disease_fetch are detail retrieval tools, not broad search tools; provide clear IDs or names. • epidemiology_search is semantic retrieval and returns evidence snippets, not a fully structured statistics database. • lang must be CN or EN; do not use values such as Chinese, English, or zh-CN. • If a name may be ambiguous, provide species, disease area, or a standard English name when possible.
