Get the GID graph schema with dynamic relations. If a graph exists, includes custom/discovered relations from that graph.
AI agents call gid_get_schema to retrieve information from GID MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves schema metadata about a graph-based software architecture representation. It performs a read-only query operation that returns structural information without creating, modifying, deleting, or executing any actions. The retrieval of schema and relation definitions constitutes information gathering with no side effects.
From the tool's definition Tool name 'gid_get_schema' and description 'Get the GID graph schema' — uses 'Get' verb indicating retrieval with no modification. Description specifies retrieving schema information and relations from an existing graph without altering state.
Attacks that exploit this kind of access
Get the GID graph schema with dynamic relations. If a graph exists, includes custom/discovered relations from that graph. It is categorised as a Read tool in the GID MCP Server MCP Server, which means it retrieves data without modifying state.
Register the GID MCP Server MCP server in PolicyLayer and add a rule for gid_get_schema: 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 GID MCP Server. Nothing to install.
gid_get_schema 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 gid_get_schema 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 gid_get_schema. 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.
gid_get_schema is provided by the GID MCP Server MCP server (potatouniverse/graph-indexed-development-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
