Validate runtime configuration and report missing optional components.
AI agents call validate_config to retrieve information from PDDL MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs configuration inspection and validation, returning diagnostic information about the system state. This is a read-only operation that retrieves and reports system configuration details without modifying any data or triggering external actions. The severity is low because even if an adversary misuses it, the blast radius is limited to information disclosure about optional components.
From the tool's definition Tool validates and reports on configuration state without modifying, deleting, or executing operations. Description indicates 'report' and 'validate' — diagnostic and informational actions with no side effects.
Attacks that exploit this kind of access
Validate runtime configuration and report missing optional components. It is categorised as a Read tool in the PDDL MCP Server MCP Server, which means it retrieves data without modifying state.
Register the PDDL MCP Server MCP server in PolicyLayer and add a rule for validate_config: 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 PDDL MCP Server. Nothing to install.
validate_config 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 validate_config 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 validate_config. 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.
validate_config is provided by the PDDL MCP Server MCP server (nbnbtm/pddl-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
