WHAT IT DOES

What list_projects does on Enhanced Knowledge Graph Memory Server

AI agents call list_projects 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 list_projects is rated Low

This is a straightforward query operation that retrieves and lists existing data from the knowledge graph without creating, modifying, deleting, or executing any operations. The read-only nature and limited scope (project IDs only) result in low severity.

From the tool's definition Tool description states it 'List all distinct project IDs' and 'Returns sorted array of projectId values' — a retrieval operation with no data modification, side effects, or external triggers.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_projects 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 list_projects, this is the rule to start with:

list_projects Allowed

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

View as policy code

policy.json

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

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 list_projects call is checked against it from then on.

FAQ

Questions about list_projects

What does the list_projects tool do? +

List all distinct project IDs in the knowledge graph. Returns sorted array of projectId values, excluding global/unscoped entities. 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 list_projects? +

Register the Enhanced Knowledge Graph Memory Server MCP server in PolicyLayer and add a rule for list_projects: 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 list_projects? +

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

Can I rate-limit list_projects? +

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

Set action: deny in the PolicyLayer policy for list_projects. 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 list_projects? +

list_projects is provided by the Enhanced Knowledge Graph Memory Server MCP server (danielsimonjr/memory-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
