MCP server metadata

Name: OpenNash Health Public Evidence
Version: 3.4.4

Capabilities

experimentalloggingprompts.listChangedresources.listChangedtools.listChangedextensions.io.modelcontextprotocol/ui

Server instructions

Specialist read-only tools for exact clinical-trial records, sites, eligibility text, registry-linked publications, record changes, biomedical identifiers, and provenance. Prefer build_trial_evidence_packet for trial questions and validate_identifier when an exact public identifier must be confirmed. Do not call OpenNash for generic health education or as a replacement for ordinary current-web research. Never use it to diagnose, choose or change treatment, determine personal trial eligibility, process PHI, or interpret medical images. Cite canonical URLs, state what each source establishes and does not establish, and report source failures as unknowns. The MCP does not use or expose the OpenNash operator's Codex authentication.
