What public-note does on Frontmcp
AI agents call public-note to retrieve information from Frontmcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why public-note is rated Low
This tool performs a simple echo/reflection operation. While it accepts authenticated input, it does not create, modify, delete, or execute operations with external effects. The description explicitly states it echoes a message, which is a read-like operation that retrieves and returns the caller's input. The lack of persistence, state modification, or code execution places it in the Read category.
From the tool's definition The tool 'echoes a message' with 'no authorities' and 'accepts any authenticated caller', indicating it returns input without persistent side effects or data manipulation.
Attacks that exploit this kind of access
The rule that runs public-note safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Frontmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For public-note, this is the rule to start with:
public-note is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Frontmcp, apply this rule, and every public-note call is checked against it from then on.
Questions about public-note
Echoes a message. No authorities — accepts any authenticated caller. It is categorised as a Read tool in the Frontmcp MCP Server, which means it retrieves data without modifying state.
Register the Front MCP server in PolicyLayer and add a rule for public-note: 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 Frontmcp. Nothing to install.
public-note 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 public-note 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 public-note. 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.
public-note is provided by the Front MCP server (agentfront/frontmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
