Get a comprehensive overview of all available MCP servers and their tools. Returns a structured list showing each server and all its available tools with descriptions.
AI agents call list_servers_with_tools to retrieve information from Code Mode 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 and lists information about available servers and their capabilities. It performs no modifications, deletions, or executions—it only reads and returns existing metadata. This is a standard Read operation with minimal risk unless the list itself contains sensitive server endpoints, but listing tools is typically informational only.
From the tool's definition Tool name 'list_servers_with_tools' and description 'Get a comprehensive overview of all available MCP servers and their tools. Returns a structured list' indicate a query/retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_servers_with_tools gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Code Mode MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_servers_with_tools:
{
"version": "1",
"default": "deny",
"tools": {
"list_servers_with_tools": {}
}
}list_servers_with_tools is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get a comprehensive overview of all available MCP servers and their tools. Returns a structured list showing each server and all its available tools with descriptions. It is categorised as a Read tool in the Code Mode MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Code Mode MCP Server MCP server in PolicyLayer and add a rule for list_servers_with_tools: 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 Code Mode MCP Server. Nothing to install.
list_servers_with_tools 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 list_servers_with_tools 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 list_servers_with_tools. 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.
list_servers_with_tools is provided by the Code Mode MCP Server MCP server (jx-codes/codemode-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Code Mode MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
