Find types that are related to a specific type
AI agents call related to retrieve information from GraphQL Schema Explorer without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries relationship information from a GraphQL schema's type system. It has no side effects, cannot modify data, execute operations, or affect external systems. It is purely informational schema exploration, identical in safety profile to other introspection tools on the server (schema, types, field, etc.).
From the tool's definition Tool performs schema introspection to 'find types that are related to a specific type' - a read-only discovery operation that queries GraphQL schema metadata without modifying anything.
Attacks that exploit this kind of access
Find types that are related to a specific type. It is categorised as a Read tool in the GraphQL Schema Explorer MCP Server, which means it retrieves data without modifying state.
Register the GraphQL Schema Explorer MCP server in PolicyLayer and add a rule for related: 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 GraphQL Schema Explorer. Nothing to install.
related 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 related 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 related. 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.
related is provided by the GraphQL Schema Explorer MCP server (martinshumberto/mcp-server-graphql). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
