Use Citewren MCP with Gemini CLI

AI search readiness MCP: score a site for ChatGPT/Claude/Perplexity crawlers. 3 free/day.

Remote MCP server (Streamable HTTP), nothing to install. Free: 3 free checks a day · Paid: $19 30-day pass or $9/mo: every fix, 15-page crawl, ready llms.txt

Set it up

1. Run the command, or add the server to settings.json under "mcpServers".
2. Start Gemini CLI and run /mcp to list the server and its tools.
3. Ask a question the tools can answer.

Run:

gemini mcp add --transport http citewren 'https://citewren.cybermaxtools.com/mcp?via=use-with-gemini-cli'

Or add it to settings.json yourself::

{
  "mcpServers": {
    "citewren": {
      "httpUrl": "https://citewren.cybermaxtools.com/mcp?via=use-with-gemini-cli"
    }
  }
}

With a paid key:

gemini mcp add --transport http --header "x-licence: YOUR_KEY" citewren 'https://citewren.cybermaxtools.com/mcp?via=use-with-gemini-cli'

Use the project file only if it is not committed with the key in it.

Where it goes:

• ~/.gemini/settings.json (user)
• .gemini/settings.json (project, the default for the add command)

Config format checked 2026-10-09 against Gemini CLI's MCP documentation.

Tools you get

Endpoint checked 2026-10-09: https://citewren.cybermaxtools.com/mcp answered an MCP initialize (protocol 2025-06-18) and tools/list with 1 tool, all marked read-only. No key was used and no tool was called.

Test the endpoint from a terminal

This lists the tools without a key and without calling any of them:

curl -s https://citewren.cybermaxtools.com/mcp \
  -H 'content-type: application/json' \
  -H 'accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

If it does not work

• Use "httpUrl" for Streamable HTTP; "url" is for the older SSE transport.
• The docs note that for unpaid-tier and Google One users, Gemini CLI was replaced by Antigravity CLI on 18 June 2026.
• The free tier has a daily limit (see the pricing line above); a paid key raises it.
