What mysql_dependency_graph does on Mysql Mcp
AI agents call mysql_dependency_graph to retrieve information from Mysql Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why mysql_dependency_graph is rated Low
This is a Read operation—it queries and retrieves database metadata (foreign key relationships, row counts, dependency information) with no modifications. However, the severity is elevated from low to medium because the intelligence it provides about cascade paths and dependencies could enable an agent to perform destructive actions if misused.
From the tool's definition Tool retrieves and analyzes foreign key dependencies, cascade paths, row counts, and circular dependency detection. Keywords: 'Get' (retrieval), 'dependency graph' (data analysis), 'structured output' (read operation).
Attacks that exploit this kind of access
The rule that runs mysql_dependency_graph safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mysql Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For mysql_dependency_graph, this is the rule to start with:
mysql_dependency_graph is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Mysql Mcp, apply this rule, and every mysql_dependency_graph call is checked against it from then on.
Questions about mysql_dependency_graph
Get the full foreign key dependency graph with cascade paths, row counts, circular dependency detection, and severity assessment. Agent-optimized structured output. It is categorised as a Read tool in the Mysql Mcp MCP Server, which means it retrieves data without modifying state.
Register the Mysql MCP server in PolicyLayer and add a rule for mysql_dependency_graph: 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 Mysql Mcp. Nothing to install.
mysql_dependency_graph is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the mysql_dependency_graph 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.
Set action: deny in the PolicyLayer policy for mysql_dependency_graph. 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.
mysql_dependency_graph is provided by the Mysql MCP server (oci:docker.io/writenotenow/mysql-mcp:v1.0.0). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
