AI agents call scan_skill_realtime to retrieve information from Arc Security without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though scan_skill_realtime only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Fetch a skill from ClawHub and perform a full security scan in real-time. Downloads the skill's SKILL.md from ClawHub registry and runs both static pattern analysis (25 regex patterns) and AI-powered intent analysis. Returns a comprehensive security report. Use this when you want a detailed scan of any skill — even ones not in Arc Security's curated database. Args: skill_name: The ClawHub skill slug (e.g., 'budget-tracker', 'source-cult-follower'). It is categorised as a Read tool in the Arc Security MCP Server, which means it retrieves data without modifying state.
Register the Arc Security MCP server in PolicyLayer and add a rule for scan_skill_realtime: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Arc Security. Nothing to install.
scan_skill_realtime is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the scan_skill_realtime rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for scan_skill_realtime. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
scan_skill_realtime is provided by the Arc Security MCP server (arc-security-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
