coql_query · Zoho CRM MCP Server MCP: Risk & Policy

WHAT IT DOES

What coql_query does on Zoho CRM MCP Server

AI agents invoke coql_query to trigger actions in Zoho CRM MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why coql_query needs a policy

While the description mentions only SELECT queries, the tool executes arbitrary COQL (CRM Object Query Language) statements against Zoho CRM. Even read-only queries can expose sensitive CRM data at scale, and the ability to run arbitrary query strings means an agent could potentially extract bulk sensitive data. The Execute category applies because it runs dynamic queries whose effects depend on arguments.

From the tool's definition 'Run a COQL SELECT query against Zoho CRM' — executes arbitrary query language statements against the CRM database

coql_query Rate-limited

coql_query stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
