Check coherence of vectors using Sheaf Laplacian energy (0=coherent, 1=contradictory)
AI agents call pr_coherence_check to retrieve information from Claude Flow without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a mathematical analysis (coherence checking via Sheaf Laplacian energy) on vector data to return a metric. It neither creates, modifies, executes external code, deletes data, nor involves financial transactions. It is a pure analytical/query operation, classifying as Read with low severity since misuse would only return misleading metrics without operational impact.
From the tool's definition Tool description indicates it 'Check[s] coherence of vectors' and returns a numerical metric (0=coherent, 1=contradictory).
Attacks that exploit this kind of access
Check coherence of vectors using Sheaf Laplacian energy (0=coherent, 1=contradictory). It is categorised as a Read tool in the Claude Flow MCP Server, which means it retrieves data without modifying state.
Register the Claude Flow MCP server in PolicyLayer and add a rule for pr_coherence_check: 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 Claude Flow. Nothing to install.
pr_coherence_check 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 pr_coherence_check 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 pr_coherence_check. 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.
pr_coherence_check is provided by the Claude Flow MCP server (claude-flow). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
