AI agents call swarm_db_stats to retrieve information from Mcp Swarm without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only operations to gather metrics and statistics from the database layer. It retrieves information about connections and storage without creating, modifying, or deleting data. Confidence is high because the description clearly indicates a statistics/monitoring function with no side effects.
From the tool's definition Tool name 'swarm_db_stats' and description '获取数据库连接和存储统计信息' (which translates to 'Get database connection and storage statistics') indicate the tool retrieves/queries statistics about database connections and storage.

Register the Mcp Swarm MCP server in PolicyLayer and add a rule for swarm_db_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 Mcp Swarm. Nothing to install.
swarm_db_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 swarm_db_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 swarm_db_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.
