LangChain uniprot mcp server Prompt/uniprot_protein_dossier

How to: LangChain uniprot mcp server uniprot_protein_dossier

client:LangChain transport:streamable-http prompt:uniprot_protein_dossier

Add uniprot mcp server to LangChain

  1. 01

    Open pip install langchain-mcp-adapters and merge this in. Keep any servers already there.

from langchain_mcp_adapters.client import MultiServerMCPClient

client = MultiServerMCPClient({
        "uniprot-mcp-server": {
            "transport": "streamable_http",
            "url": "https://uniprot.caseyjhand.com/mcp",
        }
})

tools = await client.get_tools()
  1. 02

    Save the file and restart LangChain.

  2. 03

    uniprot_protein_dossier is surfaced through the client's prompt API, fetched by name. Unlike a tool, you invoke it deliberately — LangChain will not call it for you.

  3. 04

    If it does not appear, check that uniprot mcp server is connected and that you are looking at its prompts rather than its tools.

get_tools() returns the server's tools as LangChain tools, ready for an agent. LangChain docs

Set these first

uniprot mcp server will not start until these are set, so it never reaches LangChain.

  • MCP_LOG_LEVEL

Same prompt, other clients

Read from the server itself, by connecting to it and calling prompts/list on 24 September 2026. A listing does not declare its prompts, so asking is the only way to know them, and this is what the server actually offers rather than what its listing claims. Names only are stored; connect the server for each prompt's arguments.
