Why find_similar_clusters needs a policy

This tool queries existing memory clusters to locate similar ones, which is a read-only operation that retrieves information without creating, modifying, deleting, or executing external operations. The action has no side effects on the memory system beyond returning results.

From the tool's definition Tool name 'find_similar_clusters' and description 'Find clusters similar to a given cluster' indicate a search/query operation. The verb 'find' is a retrieval operation with no modification of data.

POLICY

How to control find_similar_clusters

PolicyLayer is an MCP gateway — it sits between your AI agents and AGI MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for find_similar_clusters:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "find_similar_clusters": {}
  }
}

find_similar_clusters is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register AGI MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about find_similar_clusters

What does the find_similar_clusters tool do? +

Find clusters similar to a given cluster. It is categorised as a Read tool in the AGI MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on find_similar_clusters? +

Register the AGI MCP Server MCP server in PolicyLayer and add a rule for find_similar_clusters: 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 AGI MCP Server. Nothing to install.

What risk level is find_similar_clusters? +

find_similar_clusters is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit find_similar_clusters? +

Yes. Add a rate_limit block to the find_similar_clusters 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.

How do I block find_similar_clusters completely? +

Set action: deny in the PolicyLayer policy for find_similar_clusters. 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.

What MCP server provides find_similar_clusters? +

find_similar_clusters is provided by the AGI MCP Server MCP server (quixiai/agi-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every AGI MCP Server tool call.

Start from AGI MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
