Evaluate end-to-end task success against measurable criteria
AI agents call agent.measure_task_completion to retrieve information from ContextForge MCP Gateway without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a Read operation because it performs evaluation and measurement of existing task completion status. It retrieves metrics or assessment data to determine success criteria fulfillment, similar to a query or assessment function. No creation, modification, deletion, or external execution is indicated.
From the tool's definition The tool name 'measure_task_completion' and description 'Evaluate end-to-end task success against measurable criteria' indicate a measurement and evaluation function that retrieves or assesses information about task status.

Register the ContextForge MCP Gateway MCP server in PolicyLayer and add a rule for agent.measure_task_completion: 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 ContextForge MCP Gateway. Nothing to install.
agent.measure_task_completion 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 agent.measure_task_completion 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 agent.measure_task_completion. 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.
agent.measure_task_completion is provided by the ContextForge MCP Gateway MCP server (jrmatherly/mcp-context-forge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
