Analyze what components and features are affected by changing a node
AI agents call gid_query_impact 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 analyzes data about dependencies and affected components within a software architecture graph. It performs read-only analysis without modifying data, executing external commands, deleting information, or moving money. The 'impact' operation is analytical—it shows consequences of hypothetical changes without actually making them.
From the tool's definition Tool description: 'Analyze what components and features are affected by changing a node' — performs impact analysis via querying a graph representation. Tool name contains 'query' and 'impact' (analysis).
Attacks that exploit this kind of access
Analyze what components and features are affected by changing a node. 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_query_impact: 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_query_impact 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_query_impact 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_query_impact. 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_query_impact 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.
