MCP server
X MCP server
X (formerly Twitter) has no official MCP server, and direct X API access starts at a paid tier with strict rate caps. Modiva hosts an X MCP server with 14 typed tools, so an agent can post, publish threads, search and monitor mentions on your connected account without you standing up your own X developer project.
Since the API pricing change, most teams' X automations broke or got expensive. Modiva runs the X developer app, handles OAuth for your account and exposes posting, threading, search and mention monitoring as typed MCP tools. The agent works your account; you skip the developer-portal setup entirely.
14 typed X tools
Grouped by resource, not by platform — so the same tool names work across every connected account.

Can the agent post threads, not just single posts?
Yes. The posts_ tools support multi-part threads: the agent supplies the segments and Modiva chains the replies in order under the first post.
Do I need my own paid X API subscription?
No. You connect your X account through Modiva's OAuth flow and requests run through Modiva's X developer app. Your Modiva plan covers usage, subject to X's per-account platform rules.
Can an agent monitor mentions and replies?
Yes. messages_ and comments_ style tools surface mentions and replies to your posts, so an agent can triage and respond, and the search tools let it track keywords.
