ReleasePort's take

Light signal
editorial:auto 12d

The public search surface now includes only 12 verified providers, and extraction is limited to 8. The native Perplexity and Kilo Perplexity answer endpoints have been removed from provider schemas.

Why it matters: Affects applications using the search and extraction APIs; integration must be updated before next deployment as only 12 search providers and 8 extraction providers remain supported.

Full changelog

web-search-plus-mcp v1.0.0

The standalone MCP server now tracks the portable, source-only Web Search Plus 3.0.2 engine contract while keeping the stable web_search and web_extract tool surface.

Highlights

  • Canonical v3 request/response contracts with additive evidence, provider-attempt, routing, cache-origin, and policy receipts.
  • Truthful bounded multi-provider Research Mode with aggregate provider: research compatibility output.
  • Deterministic bounded extraction, immutable page-on-demand full-text references, and cache miss-to-hit body/provenance preservation.
  • Marker-owned v3 cache/state and guarded migration primitives.
  • MCP initialize handshake now advertises package version 1.0.0.
  • Research subprocesses receive a fixed grace window beyond their inner budget; outer timeouts become sanitized, retryable wsp.subprocess.timeout responses.

Breaking changes

  • The public search surface is now 12 verified source-result providers; extraction remains 8 providers.
  • Native Perplexity and Kilo Perplexity answer endpoints are removed from public provider schemas because they do not expose a verified source-only mode. Direct low-level calls fail closed before provider dispatch.
  • Closed response-schema consumers must allow the additive v3 evidence and provenance fields.

See MIGRATION_1_0.md for upgrade and rollback guidance.

Verification

  • 183 tests passed on Python 3.10, 3.11, and 3.12.
  • Ruff, compileall, schema/Glama drift checks, wheel, sdist, and twine check passed.
  • Fresh installed-wheel MCP stdio handshake and canonical subprocess smoke passed.
  • Wheel SHA-256: 1d78bde3c87be81f7a359d22faaf2f1ff0c1bce46d28d5c097458c83f2f3c905.
