get_rule_graph
AI agents call get_rule_graph to retrieve information from Umbrella Terminal MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name follows the 'get_' convention and is part of a legislative intelligence querying system. The graph retrieval appears to be a read-only operation that queries relationships or structure without modifying data. No description provided, which slightly reduces confidence, but the pattern of sibling tools and server purpose strongly suggest this is a data retrieval operation.
From the tool's definition Tool name 'get_rule_graph' and server context indicate data retrieval; sibling tools (get_bill, get_bill_amendments, get_bill_funding, get_bill_graph, get_bill_hearings, get_bill_history, batch_get_entities, batch_get_neighbors, find_path) are all…
Attacks that exploit this kind of access
get_rule_graph. It is categorised as a Read tool in the Umbrella Terminal MCP MCP Server, which means it retrieves data without modifying state.
Register the Umbrella Terminal MCP server in PolicyLayer and add a rule for get_rule_graph: 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 Umbrella Terminal MCP. Nothing to install.
get_rule_graph 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_rule_graph 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_rule_graph. 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_rule_graph is provided by the Umbrella Terminal MCP server (theblackcompany/umbrella_terminal_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
