AI agents invoke parse_governance_block_html to trigger processes or run actions in Agent Passport System — Cryptographic Identity for AI Agents. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
parse_governance_block_html can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

These attack patterns abuse exactly the kind of access parse_governance_block_html gives an agent. Each links to the full case and the policy that stops it:
Other execute tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Extract a governance block from an HTML page. Looks for APS governance script tags or meta tags.. It is categorised as a Execute tool in the Agent Passport System — Cryptographic Identity for AI Agents MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Agent Passport System — Cryptographic Identity for AI Agents MCP server in PolicyLayer and add a rule for parse_governance_block_html: 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 Agent Passport System — Cryptographic Identity for AI Agents. Nothing to install.
parse_governance_block_html is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the parse_governance_block_html 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 parse_governance_block_html. 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.
parse_governance_block_html is provided by the Agent Passport System — Cryptographic Identity for AI Agents MCP server (agent-passport-system-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
