Histogram of started process instances over a date range, bucketed by day/week/month. Returns per-period counts + summary (total, average, max, min bucket). Cheap — loops count_process_instances internally. See \
AI agents call process_instance_stats to retrieve information from CIB Seven MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and aggregates historical data about process instances to produce statistical summaries. It retrieves information without side effects, altering state, or triggering actions. The internal looping of count_process_instances further confirms it performs passive querying. No financial, destructive, or code execution risk.
From the tool's definition Tool returns 'Histogram of started process instances over a date range' with 'per-period counts + summary (total, average, max, min bucket)'. No modification, deletion, or execution of external operations.

Histogram of started process instances over a date range, bucketed by day/week/month. Returns per-period counts + summary (total, average, max, min bucket). Cheap — loops count_process_instances internally. See \. It is categorised as a Read tool in the CIB Seven MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CIB Seven MCP Server MCP server in PolicyLayer and add a rule for process_instance_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 CIB Seven MCP Server. Nothing to install.
process_instance_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 process_instance_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 process_instance_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.
process_instance_stats is provided by the CIB Seven MCP Server MCP server (krixerx/cib7-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
