PreClick — An MCP-native URL preflight scanning service for autonomous agents. tools (6, 2 write)

write = sends, deletes, buys or posts
  • url_scanner_async_scanwrite actionFree

    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_intentwrite actionFree

    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_resultFree

    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_statusFree

    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_scanFree

    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_intentFree

    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.

PreClick MCP Server

PreClick — An MCP-native URL preflight scanning service for autonomous agents. It scans links for threats and confirms they match the intended task before execution. Built for agentic workflows, it provides high-accuracy, context-aware browsing governance with adaptive learning.

Publisher: CybrLab.ai | Service: PreClick

Hosted Trial Tier: No API key required for up to 100 requests/day. For higher limits and stable quotas, use an API key (contact contact@cybrlab.ai).

Overview

PreClick is a URL security scanner and MCP server that enables AI agents and any client to analyze URLs for phishing, malware, and other security threats before navigation. Use it as a standalone URL scanner via the client libraries below, or connect directly via the MCP protocol.

Integrations

Client Libraries (Recommended)

The fastest way to add URL security scanning to any AI agent, automation pipeline, or application. These standalone URL scanner clients handle connection, polling, and error recovery out of the box — no MCP protocol knowledge or conformance required:

Both libraries provide a simple scan-oriented URL security scanning API (scan(url) / scanWithIntent(url, intent)) that returns results directly — phishing detection, threat analysis, and intent alignment in a single call. No protocol vocabulary, no connect() boilerplate, no manual polling for the common case.

Framework Adapters

Manual MCP Configuration

For MCP-native clients that speak the protocol directly, see Quick Start below.
