Deprecated: Fabric v4 does not support connection stats endpoint
AI agents call get_connection_stats 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.
Despite the deprecation status, the tool's purpose is to retrieve connection statistics, which is a read-only operation with no side effects. Even though it is non-functional in Fabric v4, the intended behavior classifies it as Read. Severity is low because the tool is deprecated and appears to be non-operational, limiting its practical risk.
From the tool's definition Tool name 'get_connection_stats' indicates a retrieval operation. Description states it is 'Deprecated: Fabric v4 does not support connection stats endpoint', meaning it queries statistics without modifying or executing external operations.
Attacks that exploit this kind of access
Deprecated: Fabric v4 does not support connection stats endpoint. 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 get_connection_stats: 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.
get_connection_stats 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 get_connection_stats 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 get_connection_stats. 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.
get_connection_stats 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.
