Publicly Hosted MCP Servers for Health, Academic, and Government Data
A developer has created a collection of publicly hosted MCP (Model Context Protocol) servers that are immediately available for use with any MCP client like Claude or ChatGPT. These servers require no setup, installation, API keys, authentication, or local running processes.
Available MCP Servers
The following servers are currently live and accessible:
Health and Science
https://cdc.caseyjhand.com/mcp- 1,487+ CDC public health datasets covering disease surveillance, mortality, vaccinationshttps://clinicaltrials.caseyjhand.com/mcp- ClinicalTrials.gov searchhttps://openfda.caseyjhand.com/mcp- FDA drugs, food, devices, and recalls via openFDAhttps://pubchem.caseyjhand.com/mcp- PubChem chemical databasehttps://openalex.caseyjhand.com/mcp- 270M+ academic publications via OpenAlexhttps://pubmed.caseyjhand.com/mcp- PubMed biomedical literature
Academic

Utility

How to Use
To use any of these servers, add the /mcp URL as a remote MCP server in your client. In Claude Desktop, this involves adding a remote MCP server through the interface.
Technical Details
The servers are built on @cyanheads/mcp-ts-core, an agent-native TypeScript framework maintained by the developer for building MCP servers. To build your own server, you can run:
npx @cyanheads/mcp-ts-core init my-mcp-serverThis scaffolds a project. After changing into the new directory, you can start your coding agent and describe what you want to build.
The developer notes having additional MCP servers for local tools, git operations, Obsidian, and others that aren't hosted but work as stdio servers. A full list is available on their GitHub profile.
