# FetchTwitterPostReplies

> Fetch the replies to an X/Twitter post; spends capture credits. Write access, posts toolset, MCP tool fetch_twitter_post_replies.

> **Warning:**
> This operation removes or replaces something. MCP clients see it with `destructiveHint` set, and an agent should tell you what it will change and wait for your yes.

> **Warning:**
> This operation spends capture credits, and the balance gate is the real limit on it. Prefer the `start_capture` tool, which quotes the cost first (`quote_capture`) and only runs at a price the merchant approved.
