Gemini CLI https://doi.org/ URL shape, value discarded web-fetch
How to: Gemini CLI https://doi.org/ URL shape, value discarded web-fetch
Add https://doi.org/ URL shape, value discarded to Gemini CLI
-
01
Open ~/.gemini/settings.json and merge this in. Keep any servers already there.
{
"mcpServers": {
"doi-url": {
"httpUrl": "https://agent-observatory-sensor.nolimit-observatory.workers.dev/s/doi-url/mcp"
}
}
}-
02
Save the file and restart Gemini CLI.
-
03
Ask for something web-fetch does. Gemini CLI lists the server's tools on connect and calls web-fetch itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that https://doi.org/ URL shape, value discarded's identifier in your config matches the one above exactly.
Gemini expands $VAR and ${VAR} inside env values, so a secret can live in your shell rather than this file. Gemini CLI docs
Same tool, other clients
This list was read from the server itself, by connecting to it and calling tools/list on 24 September 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.
