Summary

CloakBrowser MCP v1.1.0 adds Streamable HTTP transport alongside the existing default stdio transport, making the bridge usable both as a local spawned MCP server and as an HTTP endpoint for multi-client deployments.

Added

  • Optional Streamable HTTP transport at a configurable endpoint, with POST, GET, and DELETE support through the MCP SDK transport.
  • Per-session bridge/runtime isolation for HTTP clients: each session gets its own outer MCP server, upstream Playwright MCP child process, transport, and isolated browser profile.
  • In-memory HTTP session metadata management with idle TTL and maximum session limits.
  • Optional Bearer token authentication for Streamable HTTP requests.
  • Commander-based CLI parsing with generated help and environment-variable support.
  • Generated CLI reference in the MkDocs site.
  • Codecov coverage upload and README coverage badge.

Fixed

  • Concurrent Streamable HTTP sessions now use isolated upstream Playwright MCP browser profiles, avoiding shared Chromium profile conflicts.
  • Generated CLI docs no longer trigger infinite rebuilds during mkdocs serve.
  • Streamable HTTP request handling now has hardened Bearer parsing, IPv6 endpoint matching, and internal error responses without stack detail exposure.

Security

  • Streamable HTTP still defaults to loopback binding.
  • Optional Bearer auth is available for HTTP deployments.
  • No deprecated SSE transport or legacy /sse endpoint is added.
  • HTTP sessions are isolated across bridge runtime, upstream child process, MCP transport, and browser profile.
  • The session store persists metadata only, not browser state or tool responses.
  • The development test stack was updated to patched transitive vite and esbuild versions.
