WHAT IT DOES

What suggest_tool does on Enhanced Knowledge Graph Memory Server

AI agents call suggest_tool to retrieve information from Enhanced Knowledge Graph Memory Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why suggest_tool is rated Low

Even though suggest_tool only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs suggest_tool safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Enhanced Knowledge Graph Memory Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For suggest_tool, this is the rule to start with:

suggest_tool Allowed

suggest_tool is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Enhanced Knowledge Graph Memory Server, apply this rule, and every suggest_tool call is checked against it from then on.

FAQ

Questions about suggest_tool

What does the suggest_tool tool do? +

v2.1.0 \u2014 Suggest tools matching a task hint, ranked by successRate \xD7 recency factor (1.0 at \u22641d, linearly decays to 0.1 at \u226530d). It is categorised as a Read tool in the Enhanced Knowledge Graph Memory Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on suggest_tool? +

Register the Enhanced Knowledge Graph Memory Server MCP server in PolicyLayer and add a rule for suggest_tool: 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 Enhanced Knowledge Graph Memory Server. Nothing to install.

What risk level is suggest_tool? +

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

Can I rate-limit suggest_tool? +

Yes. Add a rate_limit block to the suggest_tool 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 suggest_tool completely? +
