WHAT IT DOES

What execute_cypher_query does on ComplianceCow MCP Server

AI agents invoke execute_cypher_query to trigger actions in ComplianceCow 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.

RISK

Why execute_cypher_query is rated High

This tool executes arbitrary Cypher queries against a compliance database containing sensitive policy, control, and audit information. While not inherently destructive (Cypher queries can be read-only), the tool permits execution of code-like queries whose effects depend entirely on the arguments provided—matching the Execute category.

From the tool's definition Tool name 'execute_cypher_query' indicates execution of Cypher queries (Neo4j graph database language). The server description mentions 'Compliance Graph' which is typically queried with Cypher.

RECOMMENDED RULE

The rule that runs execute_cypher_query safely

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

execute_cypher_query Rate-limited

execute_cypher_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.
