Protect MCP tool calls

Protect tool results at the client boundary without coupling detection to an MCP SDK implementation.

Protect a result

The supported boundary covers tools/call and resources/read results and can include tool arguments. Binary or encoded values block by default rather than being decoded speculatively.

import { createMcpBoundary, toCallToolResult } from "@redact-secret/adapter-mcp";

const boundary = await createMcpBoundary();
const outcome = await boundary.sanitizeToolCall(({ signal }) =>
  client.callTool(params, undefined, { signal }),
);
const safeResult = toCallToolResult(outcome);
