Do I need an X developer account for this Twitter MCP server?

No. You use a Reddinbox API key. Reddinbox handles the X search, so you do not apply for X API access or manage its credentials.

Can this MCP post tweets?

No. It is read-only and built for research: searching posts and reading what people say. It does not post, like or follow.

Is X search included in the free trial?

No. The free trial covers Reddit and Hacker News. X, Bluesky and Facebook need Starter or Pro.

Does the Twitter MCP work in Claude Code and Cursor?

Yes. The same endpoint works in Claude Code, Claude Desktop and Cursor. See the setup pages for each client.
