List all available metrics from the sol_metrics InfluxDB database
AI agents call list_metrics to retrieve information from Solana Metrics MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that queries and lists metrics from InfluxDB. It has no side effects—it does not create, modify, delete, or execute operations. The tool simply enumerates available data sources for monitoring purposes. Blast radius is minimal since it only reveals what metrics exist, not sensitive data values themselves.
From the tool's definition Tool name 'list_metrics' and description 'List all available metrics from the sol_metrics InfluxDB database' indicate a query operation that retrieves metadata about available metrics without modifying data.
Attacks that exploit this kind of access
List all available metrics from the sol_metrics InfluxDB database. It is categorised as a Read tool in the Solana Metrics MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Solana Metrics MCP Server MCP server in PolicyLayer and add a rule for list_metrics: 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 Solana Metrics MCP Server. Nothing to install.
list_metrics 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_metrics 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_metrics. 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_metrics is provided by the Solana Metrics MCP Server MCP server (wcampbellgalaxy/solana-metrics-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
