not analyzable — source repository is gone (deleted or private)
**The adaptive health-messaging engine for apps and agents — federally-sourced, audience-safe facts, lists & tips, keyless to try.** Call `lookup_health_fact` from any MCP client (Claude Desktop, Cursor, the OpenAI Agents SDK) with no API key and no signup, and get a CDC/NIH/USPSTF/SAMHSA-sourced fact, list, or tip with its source link. The full Signal API — sequenced cued-message streams over a 16,500+ library of federally-sourced facts, lists & tips that advance on each patient's response, each with a receptivity score + audience-safety verdict — is a free sandbox key away. Display-mode, no PHI. Not medical advice. Try it → https://uphealth.us/signal/try
Insufficient evidence to grade. This server's source has not been statically analyzed, so a low grade would only mean "nothing found", not "nothing there". We don't show a reassuring grade we can't stand behind. Attested signals (CVEs, provenance) below still apply.
Once the source is analyzed (see the analysis flag in the header), a graded score appears here. How analysis works: methodology.

[](https://mcpobservatory.com/servers/smithery:uphealth/signal/security) Heuristic, inferred signals — false positives (legitimately powerful tools, forks, language ports) are expected. Treat each as "review this", not a verdict. See the ecosystem-wide picture on the security hub, or the fleet security of uphealth.
