What generate_fk_cascade_graph does on Mcpg
AI agents call generate_fk_cascade_graph to retrieve information from Mcpg without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why generate_fk_cascade_graph is rated Low
The tool name suggests it reads database schema information about foreign key cascades and generates a graph representation. This is likely a read/analytical operation with no side effects. However, the description is empty, so confidence is reduced. It could theoretically execute queries or write output, but 'generate' in this context most likely means producing a report or visualization from existing data.
From the tool's definition Tool name: 'generate_fk_cascade_graph' — implies generating/reading a graph of foreign key cascade relationships in the database schema.
Attacks that exploit this kind of access
The rule that runs generate_fk_cascade_graph safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mcpg, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For generate_fk_cascade_graph, this is the rule to start with:
generate_fk_cascade_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 Mcpg, apply this rule, and every generate_fk_cascade_graph call is checked against it from then on.
Questions about generate_fk_cascade_graph
generate_fk_cascade_graph is a read tool on the Mcpg MCP server. It is categorised as a Read tool in the Mcpg MCP Server, which means it retrieves data without modifying state.
Register the Mcpg MCP server in PolicyLayer and add a rule for generate_fk_cascade_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 Mcpg. Nothing to install.
generate_fk_cascade_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 generate_fk_cascade_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 generate_fk_cascade_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.
generate_fk_cascade_graph is provided by the Mcpg MCP server (pypi:mcpg). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
