Part of the AgentClear — API Marketplace for AI Agents MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call discover_services to retrieve information from AgentClear — API Marketplace for AI Agents 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 discover_services 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.

discover_services 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 discover_services 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.
Set action: deny in the Intercept policy for discover_services. 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.
discover_services is provided by the AgentClear — API Marketplace for AI Agents MCP server (agentclear-ai/mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
