WHAT IT DOES

What kg_get_neighbors does on CoWork OS

AI agents call kg_get_neighbors to retrieve information from CoWork OS without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why kg_get_neighbors is rated Low

This tool queries and retrieves relationship data from a knowledge graph without creating, modifying, or deleting any information. It is a traversal operation over existing connections, analogous to a graph search or relationship lookup. No state changes, destructive operations, or external effects occur from using this tool.

From the tool's definition Tool description states 'Get entities connected to a given entity via relationships' with 'multi-hop traversal' capability.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs kg_get_neighbors safely

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

kg_get_neighbors Allowed

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

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

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

The button opens the PolicyLayer dashboard: create your workspace, connect CoWork OS, apply this rule, and every kg_get_neighbors call is checked against it from then on.

FAQ

Questions about kg_get_neighbors

What does the kg_get_neighbors tool do? +

Get entities connected to a given entity via relationships. Supports multi-hop traversal up to 3 hops deep. It is categorised as a Read tool in the CoWork OS MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on kg_get_neighbors? +

Register the CoWork OS MCP server in PolicyLayer and add a rule for kg_get_neighbors: 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 CoWork OS. Nothing to install.

What risk level is kg_get_neighbors? +

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

Can I rate-limit kg_get_neighbors? +

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

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

kg_get_neighbors is provided by the CoWork OS MCP server (CoWork-OS/CoWork-OS). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
