Search PubMed, read abstracts and summaries, and find similar articles in NCBI PubMed.
The publisher's own server: Ably MCP by usefulapi
Hosted MCP server that lets an assistant search PubMed, read article summaries and abstracts, and find similar articles.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.usefulapi%2Fpubmed-ncbi-e-utilities/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}Use your NCBI PubMed account from Claude, Cursor, or any MCP client. Search PubMed, read article summaries and abstracts, find similar articles, and read the database's search fields, all read-only. Hosted, no local install: connect with your own credentials.

Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your NCBI PubMed credentials.

On first connect you provide your NCBI API key, created in your NCBI account under Settings → API Key Management. The server validates it and stores it per user. No keys go in config files.
read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.

Cancel any time with pubmed_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running pubmed_upgrade before then undoes the cancel.

100% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
