Remote (streamable-http)

https://pubmed.caseyjhand.com/mcp Reachable (checked 2026-09-24)

Claude Code:

claude mcp add --transport http pubmed-mcp-server https://pubmed.caseyjhand.com/mcp

Or add to your MCP client config:

{
  "mcpServers": {
    "pubmed-mcp-server": {
      "url": "https://pubmed.caseyjhand.com/mcp"
    }
  }
}

Package (npm 2.10.18)

npx -y @cyanheads/[email protected]

Or add to your MCP client config:

{
  "mcpServers": {
    "pubmed-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "@cyanheads/[email protected]"
      ],
      "env": {
        "MCP_LOG_LEVEL": "<YOUR_VALUE>",
        "NCBI_API_KEY": "<YOUR_VALUE>",
        "NCBI_ADMIN_EMAIL": "<YOUR_VALUE>",
        "UNPAYWALL_EMAIL": "<YOUR_VALUE>"
      }
    }
  }
}

MCP_LOG_LEVEL — Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').
NCBI_API_KEY — NCBI API key for higher rate limits (10 req/s vs 3 req/s).
NCBI_ADMIN_EMAIL — Contact email sent with NCBI requests (recommended by NCBI).
UNPAYWALL_EMAIL — Contact email for Unpaywall. When set, pubmed_fetch_fulltext falls back to Unpaywall open-access copies for DOIs not in PMC.
