AI agents call pr_coherence_check to retrieve information from Ruflo 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 - it retrieves or computes an analysis metric on provided data without modifying any state, executing external commands, or creating irreversible changes. The tool appears to be an internal quality/validation metric for multi-agent swarm coordination, making it a low-risk analytical function.
From the tool's definition Tool performs a mathematical coherence check on vectors using Sheaf Laplacian energy, returning a numerical score (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 Ruflo MCP Server, which means it retrieves data without modifying state.
Register the Ruflo 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 Ruflo. 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 Ruflo MCP server (ruvnet/ruflo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
pr_coherence_check is one line of Ruflo's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
