Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

url
url_scanner_async_scan
Submit a URL for asynchronous security analysis. Returns immediately with a task_id. Poll with url_scanner_async_task_status to check progress, then url_scanner_async_task_result to get the scan result. Async counterpart of url_scanner_scan for clients without native MCP Tasks support.
url_scanner_async_scan_with_intent
Submit a URL with optional user intent for asynchronous security analysis. Returns immediately with a task_id. Poll with url_scanner_async_task_status to check progress, then url_scanner_async_task_result to get the scan result. Async counterpart of url_scanner_scan_with_intent for clients without native MCP Tasks support.
url_scanner_async_task_result
Retrieve the result of an asynchronous scan task. If completed, returns the full scan result (risk_score, confidence, agent_access_directive, etc.). If still running, returns status with retry_after_ms — call again after that interval. Non-blocking.
url_scanner_async_task_status
Check the status of an asynchronous scan task. Returns the current task status using native MCP task semantics (working, completed, failed, cancelled) without blocking. Use url_scanner_async_task_result to retrieve the result once completed.
url_scanner_scan
Analyze a URL for security threats (synchronous, blocks until complete or timeout). Returns risk score, confidence, agent access guidance, and intent_alignment (always not_provided for this tool; use url_scanner_scan_with_intent for intent context). For long-running scans, prefer url_scanner_async_scan which returns immediately with a task_id for polling via url_scanner_async_task_result.
url_scanner_scan_with_intent
Analyze a URL for security threats with optional user intent context (synchronous, blocks until complete or timeout). Returns risk score, confidence, agent access guidance, and intent_alignment. For long-running scans, prefer url_scanner_async_scan_with_intent which returns immediately with a task_id for polling via url_scanner_async_task_result.

Answers built from our own checks of this server.

What can PreClick — An MCP-native URL preflight scanning service for autonomous agents (formerly URLCheck). do?
It exposes 6 tools, read directly from the server on our last check. Among them: url_scanner_async_scan, url_scanner_async_scan_with_intent, url_scanner_async_task_result, url_scanner_async_task_status, url_scanner_scan, url_scanner_scan_with_intent. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is PreClick — An MCP-native URL preflight scanning service for autonomous agents (formerly URLCheck). working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 132 ms. The bar chart above shows every period we have measured.
How do I connect PreClick — An MCP-native URL preflight scanning service for autonomous agents (formerly URLCheck).?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does PreClick — An MCP-native URL preflight scanning service for autonomous agents (formerly URLCheck). need an API key?
No. PreClick — An MCP-native URL preflight scanning service for autonomous agents (formerly URLCheck). completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is PreClick — An MCP-native URL preflight scanning service for autonomous agents (formerly URLCheck).?
It answers our handshake in 132 ms on average, which is faster than 77% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is PreClick — An MCP-native URL preflight scanning service for autonomous agents (formerly URLCheck). open source?
Yes — it is published under the Apache-2.0 licence, 6 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
