Read and return the current graph structure or summary
AI agents call gid_read 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 and returns existing graph data and summaries with no capability to modify, delete, or execute operations. It is a pure read operation analogous to query or fetch operations. The low severity reflects minimal blast radius if misused by an AI agent—it can only expose information already in the system.
From the tool's definition Tool name 'gid_read' and description 'Read and return the current graph structure or summary' explicitly indicate data retrieval without side effects.
Attacks that exploit this kind of access
Read and return the current graph structure or summary. 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_read: 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_read 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_read 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_read. 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_read 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.
