AI agents call debug_mcp_config to retrieve information from Memory Bank MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Debugging configuration typically involves reading and displaying current settings without modifying them. The word 'debug' implies introspection/diagnostic read operation. Severity is low as it only exposes configuration details. Confidence is moderate because the description is minimal and doesn't explicitly confirm read-only behavior.
From the tool's definition 'Debug the current MCP configuration' — reads and reports configuration state
Documented attack patterns abuse exactly the kind of access debug_mcp_config gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Memory Bank MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for debug_mcp_config:
{
"version": "1",
"default": "deny",
"tools": {
"debug_mcp_config": {}
}
}debug_mcp_config is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Debug the current MCP configuration. It is categorised as a Read tool in the Memory Bank MCP MCP Server, which means it retrieves data without modifying state.
Register the Memory Bank MCP server in PolicyLayer and add a rule for debug_mcp_config: 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 Memory Bank MCP. Nothing to install.
debug_mcp_config 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 debug_mcp_config 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 debug_mcp_config. 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.
debug_mcp_config is provided by the Memory Bank MCP server (movibe/memory-bank-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Memory Bank MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
