List all service tokens in your account
AI agents call list_service_tokens to retrieve information from Equinix Fabric MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates service tokens without creating, modifying, or deleting them. It is fundamentally a Read operation. Severity is medium rather than low because service tokens are security-sensitive credentials; unauthorized listing could expose token identifiers and metadata that might aid in further attacks, though the tokens themselves are not directly exposed in a typical list operation.
From the tool's definition Tool name 'list_service_tokens' and description 'List all service tokens in your account' indicate a query/retrieval operation with no modification or deletion of data.
Attacks that exploit this kind of access
List all service tokens in your account. It is categorised as a Read tool in the Equinix Fabric MCP MCP Server, which means it retrieves data without modifying state.
Register the Equinix Fabric MCP server in PolicyLayer and add a rule for list_service_tokens: 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 Equinix Fabric MCP. Nothing to install.
list_service_tokens 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_service_tokens 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_service_tokens. 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_service_tokens is provided by the Equinix Fabric MCP server (sliuuu/equinix-fabric-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
