swarm_validate_with_gates · Mcp Swarm MCP: Risk & Policy

WHAT IT DOES

What swarm_validate_with_gates does on Mcp Swarm

AI agents invoke swarm_validate_with_gates to trigger actions in Mcp Swarm. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why swarm_validate_with_gates needs a policy

Quality gate validation typically involves running checks, tests, or analysis pipelines against code or documents. This constitutes executing external operations rather than a simple read or write. The description is minimal and in Chinese, limiting confidence. Severity is medium as misuse could trigger unintended automated checks or expose content to external validation services, but blast radius is limited.

From the tool's definition '验证内容（代码、文档等）' — validates content using quality gates, implying execution of validation/linting logic against provided artifacts

Verdict

swarm_validate_with_gates Rate-limited

swarm_validate_with_gates stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about swarm_validate_with_gates

What does the swarm_validate_with_gates tool do? +

使用质量门控验证内容（代码、文档等）。. It is categorised as a Execute tool in the Mcp Swarm MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on swarm_validate_with_gates? +

Register the Mcp Swarm MCP server in PolicyLayer and add a rule for swarm_validate_with_gates: 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.

What risk level is swarm_validate_with_gates? +

swarm_validate_with_gates is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit swarm_validate_with_gates? +

Yes. Add a rate_limit block to the swarm_validate_with_gates 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.

How do I block swarm_validate_with_gates completely? +

Set action: deny in the PolicyLayer policy for swarm_validate_with_gates. 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.

What MCP server provides swarm_validate_with_gates? +

swarm_validate_with_gates 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.
