AI agents call get_pipeline_metrics to retrieve information from MCP Ashby Connector without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves analytical data about job pipelines without creating, modifying, or deleting any records. It is a pure data retrieval operation with no side effects on the Applicant Tracking System state. The blast radius of misuse is minimal—an agent could only access metrics data that may already be visible through the ATS interface.
From the tool's definition Tool name 'get_pipeline_metrics' and description 'Get pipeline metrics for jobs' indicate a retrieval operation with no modification capability. The verb 'Get' and the metrics query pattern are characteristic of read-only operations.
Documented attack patterns abuse exactly the kind of access get_pipeline_metrics gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Ashby Connector, and nothing reaches the server without passing your rules. This is the rule we recommend for get_pipeline_metrics:
{
"version": "1",
"default": "deny",
"tools": {
"get_pipeline_metrics": {}
}
} get_pipeline_metrics is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get pipeline metrics for jobs. It is categorised as a Read tool in the MCP Ashby Connector MCP Server, which means it retrieves data without modifying state.
Register the MCP Ashby Connector MCP server in PolicyLayer and add a rule for get_pipeline_metrics: 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 MCP Ashby Connector. Nothing to install.
get_pipeline_metrics 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 get_pipeline_metrics 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 get_pipeline_metrics. 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.
get_pipeline_metrics is provided by the MCP Ashby Connector MCP server (thnico/mcp-ashby). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Ashby Connector, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
