Get statistics about the code relationship graph.
AI agents call get_graph_statistics to retrieve information from Codebase Contextifier 9000 without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns aggregated metrics about an existing code graph without creating, modifying, deleting, or executing any operations. It has no side effects and poses minimal security risk—an agent could only retrieve statistical summaries of code relationships that are already indexed. No data is altered, no code is executed, and no irreversible actions are possible.
From the tool's definition Tool name 'get_graph_statistics' and description 'Get statistics about the code relationship graph' indicate data retrieval with no modification. The verb 'Get' combined with 'statistics' (computed aggregates) is read-only.
Attacks that exploit this kind of access
Get statistics about the code relationship graph. It is categorised as a Read tool in the Codebase Contextifier 9000 MCP Server, which means it retrieves data without modifying state.
Register the Codebase Contextifier 9000 MCP server in PolicyLayer and add a rule for get_graph_statistics: 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 Codebase Contextifier 9000. Nothing to install.
get_graph_statistics 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 get_graph_statistics 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 get_graph_statistics. 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.
get_graph_statistics is provided by the Codebase Contextifier 9000 MCP server (jarmentor/codebase-contextifier-9000). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
