List all configured downstream MCP servers and their live connection state. Use this when you need to know which servers are connected, how many tools they expose, or whether an upstream integration is unavailable. Returns a JSON array of server health summaries.
AI agents call sint__servers to retrieve information from SINT Protocol without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a pure information-retrieval operation—listing server configurations and their connection states. It has no side effects and does not modify any data, execute code, delete resources, or commit financial obligations. The misuse risk is minimal; an agent cannot cause harm by checking server availability and counts.
From the tool's definition Tool name 'sint__servers' and description explicitly states it 'List[s] all configured downstream MCP servers' and 'Returns a JSON array of server health summaries.' The verb 'list' and the focus on querying state ('know which servers are connected, how many…
Documented attack patterns abuse exactly the kind of access sint__servers gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SINT Protocol, and nothing reaches the server without passing your rules. This is the rule we recommend for sint__servers:
{
"version": "1",
"default": "deny",
"tools": {
"sint__servers": {}
}
} sint__servers is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all configured downstream MCP servers and their live connection state. Use this when you need to know which servers are connected, how many tools they expose, or whether an upstream integration is unavailable. Returns a JSON array of server health summaries. It is categorised as a Read tool in the SINT Protocol MCP Server, which means it retrieves data without modifying state.
Register the SINT Protocol MCP server in PolicyLayer and add a rule for sint__servers: 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 SINT Protocol. Nothing to install.
sint__servers 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 sint__servers 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 sint__servers. 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.
sint__servers is provided by the SINT Protocol MCP server (sint-ai/sint-protocol). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from SINT Protocol, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
