AI agents call get-peers to retrieve information from Consul MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves peer information from Consul without creating, modifying, deleting, or executing any operations. It is a straightforward read-only query with minimal blast radius if misused by an AI agent—at worst, it exposes peer information that may already be intended for query access.
From the tool's definition Tool name 'get-peers' and description 'Get the current peers' indicate a retrieval operation with no modification or side effects. The action is a query that returns current peer information from Consul.
Documented attack patterns abuse exactly the kind of access get-peers gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Consul MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get-peers:
{
"version": "1",
"default": "deny",
"tools": {
"get-peers": {}
}
}get-peers is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get the current peers. It is categorised as a Read tool in the Consul MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Consul MCP Server MCP server in PolicyLayer and add a rule for get-peers: 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 Consul MCP Server. Nothing to install.
get-peers 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 get-peers 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 get-peers. 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.
get-peers is provided by the Consul MCP Server MCP server (kocierik/consul-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Consul MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
