AI agents call swarm_code_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 retrieves aggregate statistics about stored code in MongoDB. It performs a read-only query operation to gather metrics or summaries, with no capacity to modify data, execute code, or cause side effects. The blast radius of misuse is minimal—an agent could only obtain metadata about code storage patterns, which poses low risk.
From the tool's definition Tool name 'swarm_code_stats' and description indicating it 'retrieves statistical information' (获取...统计信息) from MongoDB code storage. The verb '获取' (get/retrieve) indicates a query/retrieval operation with no modification or execution.
Attacks that exploit this kind of access
获取 MongoDB 代码存储的统计信息。. It is categorised as a Read tool in the Mcp Swarm MCP Server, which means it retrieves data without modifying state.
Register the Mcp Swarm MCP server in PolicyLayer and add a rule for swarm_code_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_code_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_code_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_code_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.
swarm_code_stats is provided by the Mcp Swarm MCP server (moselu/mcp-swarm). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
