Get statistical overview of the knowledge graph including node count, edge count, density, connected components, and degree distribution. Provides insight into the overall structure and complexity of the knowledge network.
AI agents call get_graph_statistics to retrieve information from TDZ C64 Knowledge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only statistical analysis tool. It retrieves and aggregates metrics about an existing knowledge graph (node count, edge count, density, connected components, degree distribution) without creating, modifying, deleting, or executing code. The blast radius if misused is negligible—an AI agent could only over-query or spam requests, not corrupt data or trigger external actions.
From the tool's definition Tool description states it 'Get[s] statistical overview' and 'Provides insight into the overall structure' — purely retrieval operations with no modification, deletion, or execution of external code. No side effects beyond querying graph metadata.
Attacks that exploit this kind of access
Get statistical overview of the knowledge graph including node count, edge count, density, connected components, and degree distribution. Provides insight into the overall structure and complexity of the knowledge network. It is categorised as a Read tool in the TDZ C64 Knowledge MCP Server, which means it retrieves data without modifying state.
Register the TDZ C64 Knowledge 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 TDZ C64 Knowledge. 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 TDZ C64 Knowledge MCP server (michaeltroelsen/tdz-c64-knowledge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
