Is Xcatcher Remote MCP live?

Yes — it answered the hub's last check (checked 1h ago). It answered 99% of checks over the last 30 days.

Is Xcatcher Remote MCP free to use?

Yes — the hub reached it with no key and no payment.

What tools does Xcatcher Remote MCP have?

17 tools: get_result_download_url, get_result_preview, get_direct_result_preview, preflight_crawl, get_x402_quote, submit_direct_crawl_payment, get_direct_task_status, create_crawl_task, ….

Is Xcatcher Remote MCP safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• get_account_balance reads open 20h ago

  Return the account attached to the current Bearer API key and its points balance. Use before creating a task to estimate whether an x402 top-up will be needed. Read-only.

• create_crawl_task changes data unknown never probed

  Create a crawl task for one or more X (Twitter) usernames. Side effects: creates a new task AND consumes points. If points are insufficient, upstream returns HTTP 402 with PAYMENT-REQUIRED (quote). This tool surfaces it as error.code=PAYMENT_REQUIRED with payment_required payload so agents can request spending approval, top up, then retry safely. Modes: - normal: Fast latest-post snapshot at scale (fresh-feed monitoring). Optimized for high-throughput batch retrieval. - deep: Deeper per-user collection/enrichment (typically slower; higher resource usage). Use when you need more than a quick latest-post snapshot. Performance note: Normal mode is optimized for a small latest-post snapshot per handle. Actual completeness and latency depend on X availability, upstream limits, and network conditions. Batching: For very large sets, split users into batches. Suggested upper bound per task: 500 users (configurable via MAX_USERS_PER_TASK). Reliability: - Use idempotency_key to make retries safe (avoid duplicate charges). - After creation, poll get_task_status every 5–10s until has_result=true. - Then call get_result_download_url (download still requires the same Bearer token).
