WHAT IT DOES

What harvest_resolve_entities does on Harvest MCP Server

AI agents call harvest_resolve_entities to retrieve information from Harvest MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why harvest_resolve_entities needs a policy

This tool only searches and retrieves entity information (IDs) by matching names. It performs no writes, executions, deletions, or financial operations. The blast radius is minimal as it only reads data.

From the tool's definition 'Searches clients, projects, users, and tasks by name' and 'Resolve entity names to IDs using fuzzy matching' — purely a lookup/search operation with no side effects

Documented attack patterns abuse exactly the kind of access harvest_resolve_entities gives an agent:

POLICY

How to control harvest_resolve_entities

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

policy.json

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

harvest_resolve_entities 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 Harvest 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.
