AI agents call vonage_api_reference to retrieve information from Vonage Documentation Mcp 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 vonage_api_reference 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.

Provides a direct link or detailed information from the Vonage API reference documentation for a specific API endpoint. Use this when the user's query is highly technical and related to a specific endpoint, like API parameters, request bodies, or response schemas.. It is categorised as a Read tool in the Vonage Documentation Mcp MCP Server, which means it retrieves data without modifying state.
Register the Vonage Documentation MCP server in PolicyLayer and add a rule for vonage_api_reference: 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 Vonage Documentation Mcp. Nothing to install.
vonage_api_reference 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 vonage_api_reference 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 vonage_api_reference. 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.
vonage_api_reference is provided by the Vonage Documentation MCP server (https://documentation-mcp.vonage.dev/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
