Fetch recent public X/Twitter posts by named handle for monitoring, comparison, OSINT, and research.
The publisher's own server: posts.design
Remote MCP server that fetches recent public X (Twitter) posts for named handles, with free preflight checks and optional USDC pay-per-crawl.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.lvpiggyqq%2Fxcatcher/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}Xcatcher gives AI agents recent public X (formerly Twitter) posts for one or many named account handles. It combines a public Remote MCP server, an installable Agent Skill, structured JSON results, a REST API, and accountless x402 v2 USDC pay-per-crawl on Base.
For an AI agent, provide the canonical Skill URL:
The standalone SKILL.md contains the complete Remote MCP workflow. For a persistent installation in Codex, Claude Code, Cursor, Cline, and other Agent Skills compatible hosts, use the dedicated minimal Skill repository:
GitHub CLI users can inspect and install the same package with:
See the installation guide or the dedicated xcatcher-skill repository. A versioned ZIP remains available for hosts that install bundles directly:
For an MCP client, connect the Streamable HTTP endpoint:
Tool discovery and the accountless x402 tools do not require an Xcatcher API key. An optional Authorization: Bearer xc_live_... header unlocks account, points, and private task tools.
The input is 1–500 named handles or profile URLs per task. Xcatcher is not keyword search, a complete historical archive, or the full X firehose.
get_service_info to inspect live capabilities and prices.preflight_crawl to normalize handles and preview modeled cost with no side effects. Use get_sample_result when the user wants to inspect the synthetic output contract.get_direct_crawl_payment with the normalized input.PAYMENT-SIGNATURE with the same handles and mode. Use submit_direct_crawl_payment only when the MCP host can inject the signature through a host-managed secret channel.get_direct_task_status, then read structured rows with get_direct_result_preview.Existing API-key users can instead call create_crawl_task, wait_for_task, and get_result_preview. The Agent Skill contains the complete decision tree, retry rules, and security boundaries.
The dependency-free smoke test calls only anonymous, read-only operations: tools/list, preflight_crawl, and get_sample_result. It never requests a payment requirement, creates a task, submits a signature, or moves funds.
The same test runs in GitHub Actions on changes and once per day. Public Skill security evidence is available on the AgentSkill.sh audit page, and current MCP tool definitions are visible on the verified Glama connector.

Always treat the live 402 response—not cached documentation—as authoritative for payment terms.

Get Xcatcher service info
Read Xcatcher's live capabilities, prices, limits, endpoints, and recommended agent workflow. Call this first when planning a crawl or when cached documentation may be stale. No points are consumed.
Takes no parameters.
Preflight an Xcatcher crawl for free
Normalize and deduplicate X handles, validate the mode, and preview the current modeled points/USDC cost. This free read-only check requires no account, creates no quote or task, and moves no funds. Use it before requesting a live x402 payment challenge.
modeusersrequiredInspect a free Xcatcher sample result
Return a stable synthetic example of Xcatcher's paginated result and coverage metadata. No live X data is fetched, no account is needed, no task or quote is created, and no funds move.
Takes no parameters.
Get Xcatcher balance
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.
Takes no parameters.
List Xcatcher crawl tasks
List recent tasks owned by the current Bearer API key, newest first. Use next_before_id for cursor pagination. Read-only and does not consume points.
limitbefore_idGet an x402 top-up quote
Create a short-lived USDC quote for a requested number of Xcatcher points. Returns the exact live amount and supported Base/Solana payment requirements; it does not move funds. Ask the user before signing or sending any payment.
pointsrequiredGet accountless crawl payment requirements
Create a request-bound x402 v2 payment requirement for an accountless crawl. Use this only for the accountless x402 path after preflight_crawl; API-key accounts use create_crawl_task instead. Normal requests use progressive batch pricing, so quote the complete deduplicated handle list together. This does not move funds. Return payment_required_b64 unchanged to an x402-compatible wallet/client; the live amount, asset, network, destination, and quoteId are authoritative.
modeusersrequiredPay for and create an accountless crawl
Submit an x402 v2 PAYMENT-SIGNATURE for the exact users/mode used by get_direct_crawl_payment. This may settle USDC and create a crawl task. Call only after explicit spending approval. On success, securely save task_token: it grants task-scoped result access for seven days.
modeusersrequiredpayment_signature_b64requiredGet accountless paid task status
Read an accountless paid crawl using its task_id and task-scoped token. Use this instead of get_task_status for an accountless x402 task. Poll every 5-10 seconds until task.has_result is true or it reaches failed/cancelled.
task_idrequiredtask_tokenrequiredPreview accountless paid crawl results
Return structured JSON rows for a completed accountless paid crawl. Use this instead of get_result_preview for an accountless x402 task; API-key accounts use get_result_preview. Use offset for pagination; the task token is required and should be treated as a secret.
limitoffsettask_idrequiredtask_tokenrequiredCreate an X crawl task
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).
modeusersrequiredidempotency_keyCredit points from an x402 payment
Top up points for the CURRENT Bearer key using x402 proof. Inputs: - quote_id: returned by PAYMENT-REQUIRED (or /api/v1/x402/quote) - payment_signature_b64: base64(JSON) that will be passed as HTTP header PAYMENT-SIGNATURE Side effects: credits points to the same Bearer key (no key rotation). On success returns credited_points and balance_after (shape depends on upstream).
quote_idrequiredpayment_signature_b64requiredGet crawl task status
Get API-key account task status by task_id (read-only); accountless x402 tasks use get_direct_task_status instead. Recommended polling interval: every 5–10 seconds until has_result=true. Returns safe structured state, result metadata, and authenticated result URLs; server filesystem paths are never exposed.
task_idrequiredWait for a crawl task
Poll a crawl task server-side until it has a result, reaches a terminal failure/cancelled state, or the bounded timeout expires. Read-only and cheaper for agent context than repeated manual polling.
task_idrequiredtimeout_secondspoll_interval_secondsPreview crawl results
Return up to 100 result rows from an API-key account task as native structured JSON for direct agent analysis; accountless x402 tasks use get_direct_result_preview instead. Use offset/next_offset for pagination; this does not download or parse XLSX. Use after has_result=true; use get_result_download_url when the complete XLSX is required. Read-only.
limitoffsettask_idrequiredGet result download URL
Get an absolute download URL for a task result (read-only). If the task is not finished, returns ok=false with code=RESULT_NOT_READY (HTTP 409). Downloading the URL requires the same Authorization: Bearer token.
task_idrequiredCancel a queued crawl task
Cancel a queued task by task_id. Side effects: changes task state. Xcatcher refunds cost_points when a queued task is successfully cancelled.
task_idrequired100% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
