Group similar notes into clusters using machine learning
AI agents call analysis-cluster-notes to retrieve information from MCP Index Notes without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool analyzes and retrieves insights from notes by performing unsupervised clustering. It does not create, modify, or delete notes; it does not execute arbitrary code or external operations; and it has no financial impact. It is a read-category tool that processes existing data to produce analytical results.
From the tool's definition Tool performs clustering analysis on notes using machine learning - a computational read operation that groups and analyzes existing data without modifying, deleting, or executing external operations.
Attacks that exploit this kind of access
Group similar notes into clusters using machine learning. It is categorised as a Read tool in the MCP Index Notes MCP Server, which means it retrieves data without modifying state.
Register the MCP Index Notes MCP server in PolicyLayer and add a rule for analysis-cluster-notes: 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 Index Notes. Nothing to install.
analysis-cluster-notes 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 analysis-cluster-notes 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 analysis-cluster-notes. 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.
analysis-cluster-notes is provided by the MCP Index Notes MCP server (vjsr007/mcp-index-notes). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
