Part of the MERX - TRON Resource Exchange MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

merx-mcp Read

AI agents call list_providers to retrieve information from MERX - TRON Resource Exchange without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

Even though list_providers only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

What does the list_providers tool do? +

List all Merx providers with types, durations, and availability. No authentication required.. It is categorised as a Read tool in the MERX - TRON Resource Exchange MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on list_providers? +

Add a rule in your Intercept YAML policy under the tools section for list_providers. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the MERX - TRON Resource Exchange MCP server.

What risk level is list_providers? +

list_providers is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit list_providers? +

Yes. Add a rate_limit block to the list_providers rule in your Intercept 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.

How do I block list_providers completely? +

Set action: deny in the Intercept policy for list_providers. 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.

What MCP server provides list_providers? +

list_providers is provided by the MERX - TRON Resource Exchange MCP server (merx-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
