- The MCP HTTP client sends JSON-RPC requests, including tool arguments, to arbitrary user-supplied URLs with no allowlist, trust boundary warning, or destination validation. This can expose sensitive prompts, secrets, or workspace-derived data to attacker-controlled endpoints and also enables SSRF-style access to internal services if the host environment has network reachability.
