Analyze logical flow and consistency of text using rule-based and LLM metrics
AI agents call quality.measure_coherence 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 tool reads text input and returns metrics about its logical coherence and consistency. There are no side effects, no data modification, no code execution on external systems, and no destructive operations. It is a pure analytical/query operation that evaluates properties of provided content.
From the tool's definition Tool 'quality.measure_coherence' performs analysis using 'rule-based and LLM metrics' on text. The verb 'analyze' and the phrase 'measure' indicate data retrieval and inspection without modification, creation, or deletion of data.
Attacks that exploit this kind of access
Analyze logical flow and consistency of text using rule-based and LLM metrics. It is categorised as a Read tool in the ContextForge MCP Gateway MCP Server, which means it retrieves data without modifying state.
Register the ContextForge MCP Gateway MCP server in PolicyLayer and add a rule for quality.measure_coherence: 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.
quality.measure_coherence 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 quality.measure_coherence 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 quality.measure_coherence. 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.
quality.measure_coherence 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.
