Test connectivity to craft.io API
AI agents call craft_ping to retrieve information from Craft MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a connectivity test that checks the availability and responsiveness of an external service. It has no side effects, does not retrieve substantive data, and does not modify any state. It is purely diagnostic in nature, making it a Read category operation with low severity since misuse would only result in multiple ping requests.
From the tool's definition Tool name 'craft_ping' and description 'Test connectivity to craft.io API' indicate a diagnostic operation that queries API status without retrieving or modifying data.
Attacks that exploit this kind of access
Test connectivity to craft.io API. It is categorised as a Read tool in the Craft MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Craft MCP Server MCP server in PolicyLayer and add a rule for craft_ping: 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 Craft MCP Server. Nothing to install.
craft_ping 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 craft_ping 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 craft_ping. 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.
craft_ping is provided by the Craft MCP Server MCP server (upstackjade/craft_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
