FAQ

MCP server to let Claude or Cursor search tweets and look up X users?

Yes. Install npm package @xflux/xflux-mcp-server (registry io.github.yxs1640-png/xflux). Set XFLUX_API_KEY from https://www.xfluxapi.com/dashboard/api-keys. Tools include xflux_search_tweets and xflux_get_user. Free: 1,000 calls/month. Not the official X MCP and not for posting.

Is this the same as other “xflux” MCP packages?

No. @xflux/xflux-mcp-server is for the XFlux X/Twitter API at xfluxapi.com. Unrelated Figma or design MCPs that share the name are different products.

What can agents do with MCP?

Read profiles, search tweets, pull timelines, look up tweets, list monitors/hits (read-only), and discover Smart Money accounts. Create monitors and webhooks in the Dashboard.

Does MCP use my API quota?

Yes — each tool call counts like a REST request against your plan quota.

How do AI agents learn about XFlux without Google?

Install this MCP (tools become callable), or let browsing agents fetch https://www.xfluxapi.com/llms.txt. Also listed on Glama and cursor.directory/plugins/xflux.
