Assess an MCP server deployment against the OWASP MCP Top 10 security risks.
AI agents call assess_mcp_security to retrieve information from Security Framework without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and analyzes security risk information by cross-referencing an MCP deployment against known security frameworks. This is a read-only, analytical operation with no side effects—no data is created, modified, deleted, or executed. No financial transactions occur. The blast radius of misuse is minimal; incorrect assessment results inform decisions but do not directly harm systems.
From the tool's definition Tool name 'assess_mcp_security' and description indicate it performs assessment/evaluation against OWASP MCP Top 10 risks.
Documented attack patterns abuse exactly the kind of access assess_mcp_security gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Security Framework, and nothing reaches the server without passing your rules. This is the rule we recommend for assess_mcp_security:
{
"version": "1",
"default": "deny",
"tools": {
"assess_mcp_security": {}
}
}assess_mcp_security is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Assess an MCP server deployment against the OWASP MCP Top 10 security risks. It is categorised as a Read tool in the Security Framework MCP Server, which means it retrieves data without modifying state.
Register the Security Framework MCP server in PolicyLayer and add a rule for assess_mcp_security: 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 Security Framework. Nothing to install.
assess_mcp_security 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 assess_mcp_security 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 assess_mcp_security. 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.
assess_mcp_security is provided by the Security Framework MCP server (zer0-kr/security-framework-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Security Framework, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
