Grok ensembl mcp server ensembl_get_sequence
How to: Grok ensembl mcp server ensembl_get_sequence
Add ensembl mcp server to Grok
-
01
Open .mcp.json (in your project root) and merge this in. Keep any servers already there.
{
"mcpServers": {
"ensembl-mcp-server": {
"type": "http",
"url": "https://ensembl.caseyjhand.com/mcp"
}
}
}-
02
Save the file and restart Grok.
-
03
Ask for something ensembl_get_sequence does. Grok lists the server's tools on connect and calls ensembl_get_sequence itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that ensembl mcp server's identifier in your config matches the one above exactly.
Grok Build reads Claude Code's .mcp.json and Claude Desktop's config unchanged, so a server you have already set up there needs nothing new. The Grok web app and X integration do not take custom servers. Grok docs
Set these first
ensembl mcp server will not start until these are set, so ensembl_get_sequence never becomes available.

This list was read from the server itself, by connecting to it and calling tools/list on 14 November 2026. It is what
the server actually exposes, not what its listing claims.
Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
