Retrieve details for a specific estimate.
AI agents call get_estimate_details 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.
This tool only fetches/reads data about an existing estimate. It has no side effects, does not modify any data, and cannot cause harm if misused beyond exposing estimate information.

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 get_estimate_details:
{
"version": "1",
"default": "deny",
"tools": {
"get_estimate_details": {}
}
}get_estimate_details is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
