List all available FM8 mappings (route, label, cc).
AI agents call list_mappings to retrieve information from FM8 MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation—listing existing mappings—with no side effects, no data modification, and no execution of external operations. It has minimal blast radius as misuse would only expose existing configuration information.
From the tool's definition Tool name 'list_mappings' and description 'List all available FM8 mappings' indicate a query operation that retrieves and displays configuration data without modifying state.
Attacks that exploit this kind of access
List all available FM8 mappings (route, label, cc). It is categorised as a Read tool in the FM8 MCP Server MCP Server, which means it retrieves data without modifying state.
Register the FM8 MCP Server MCP server in PolicyLayer and add a rule for list_mappings: 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 FM8 MCP Server. Nothing to install.
list_mappings 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_mappings 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_mappings. 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_mappings is provided by the FM8 MCP Server MCP server (thesigma1receptor/fm8mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
