get_corpus_stats
AI agents call get_corpus_stats 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.
This tool appears to fetch or calculate statistics about a corpus (likely legislative bills or statutes). The name and server context suggest data retrieval only. The empty description lowers confidence slightly, but the pattern of sibling Read tools on the same server strongly indicates this is a query/retrieval operation with no side effects. No financial, destructive, or code execution capability is evident.
From the tool's definition Tool name 'get_corpus_stats' indicates retrieval of statistical data. Description is empty, but the server context (legislative intelligence queries) and sibling tools (batch_get_*, get_bill*, find_path) are all Read operations that retrieve or analyze data…

get_corpus_stats. 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_corpus_stats: 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_corpus_stats 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_corpus_stats 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_corpus_stats. 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_corpus_stats 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.
