Get full details of a captured HTTP exchange including headers and body previews.
AI agents call proxy_get_exchange to retrieve information from Proxy without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays information about captured network traffic. While it returns sensitive data (HTTP headers, body content) that could include credentials, cookies, or other confidential information, the operation itself is read-only with no side effects.
From the tool's definition Tool name contains 'get' and description states it 'Get[s] full details of a captured HTTP exchange including headers and body previews' — purely retrieval of previously captured network traffic data with no modification, deletion, or execution capability.
Documented attack patterns abuse exactly the kind of access proxy_get_exchange gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Proxy, and nothing reaches the server without passing your rules. This is the rule we recommend for proxy_get_exchange:
{
"version": "1",
"default": "deny",
"tools": {
"proxy_get_exchange": {}
}
}proxy_get_exchange is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get full details of a captured HTTP exchange including headers and body previews. It is categorised as a Read tool in the Proxy MCP Server, which means it retrieves data without modifying state.
Register the Proxy MCP server in PolicyLayer and add a rule for proxy_get_exchange: 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 Proxy. Nothing to install.
proxy_get_exchange 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 proxy_get_exchange 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 proxy_get_exchange. 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.
proxy_get_exchange is provided by the Proxy MCP server (yfe404/proxy-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Proxy, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
