Returns the exact input JSON for testing serialization
AI agents call echo-json to retrieve information from MCP Express Server for Netlify without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool simply echoes back whatever JSON input it receives, performing no side effects, no data modification, no execution, and no deletion. It is a pure read/reflect operation used for testing purposes only.

Returns the exact input JSON for testing serialization. It is categorised as a Read tool in the MCP Express Server for Netlify MCP Server, which means it retrieves data without modifying state.
Register the MCP Express Server for Netlify MCP server in PolicyLayer and add a rule for echo-json: 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 MCP Express Server for Netlify. Nothing to install.
echo-json 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 echo-json 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 echo-json. 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.
echo-json is provided by the MCP Express Server for Netlify MCP server (lutfi-haslab/mcp-server-netlify). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
