X API — MCP (reads) + REST (writes), BYOK
Connects the user's own X developer app so this agent can:
- Read via the official hosted X MCP (
https://api.x.com/mcp) — 24 tools - Write via the X v2 REST API (
https://api.x.com/2/...) — post / delete / like / retweet / reply / DM
Why BYOK (not a shared Starchild app): X write access is per-app rate-limited
(~app-wide caps), pay-per-use billed to the app owner, and TOS liability sits with
the app owner. A shared app = single point of failure + neighbors starving each
other + concentrated billing + content-moderation liability. So every user brings
their own app + OAuth token. The token lives only on this machine (~/.xurl),
never proxied.
