#[unsafe(no_mangle)]pub unsafe extern "C" fn nemo_relay_register_tool_request_intercept(
    name: *const c_char,
    priority: i32,
    break_chain: bool,
    cb: NemoRelayToolSanitizeCb,
    user_data: *mut c_void,
    free_fn: NemoRelayFreeFn,
) -> NemoRelayStatus

Register a tool request intercept. The callback can transform tool arguments before execution. Runs after request guardrails in the middleware pipeline.

Parameters

  • name: Unique intercept name.
  • priority: Execution priority (lower runs first).
  • break_chain: If true, stop processing further intercepts after this one.
  • cb: Transform callback that receives tool name and args JSON, returns modified args JSON.
  • user_data: Opaque pointer passed to cb.
  • free_fn: Optional destructor for user_data.

The callback is fallible. To signal failure, call crate::error::nemo_relay_set_last_error_message from C and return null.

Safety

name must be a valid C string. cb must be a valid function pointer.
