Implements authoritative_location redirect following per the AdCP specification. When a publisher's adagents.json contains an authoritative_location field instead of authorized_agents, the function now fetches the referenced URL to get the actual authorization data. - Follows redirects with loop detection and max depth limit (5) - Validates HTTPS requirement for authoritative_location URLs - Handles edge case where both fields are present (authorized_agents takes precedence) - Adds comprehensive tests for redirect scenarios Closes #114 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Schema version 2.6.0 is not yet published on adcontextprotocol.org. Downgrade to 2.5.3 (latest available) to unblock CI. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

#117) * feat: add V3 protocol support (Governance, Content Standards, SI, CLI) Add comprehensive V3 ADCP protocol support including: Server Framework: - Add GovernanceHandler for property list management - Add ContentStandardsHandler for content calibration - Add SponsoredIntelligenceHandler for conversational AI sponsorship - Add governance method stubs to all protocol handlers - Add MCP tool definitions for all V3 operations Client: - Add typed client methods for all V3 operations - Export all V3 types from adcp.types Protocol Adapters: - Add governance methods to protocol base class - Add governance implementations to MCP and A2A adapters CLI: - Add all V3 operations to command-line client: - Protocol Discovery: get_adcp_capabilities - Content Standards: 7 operations - Sponsored Intelligence: 4 operations - Governance: 5 operations Types: - Sync schemas with ADCP 2.6+ spec - Generate types for V3 domains Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix: resolve ruff linting errors - Fix import block sorting (I001) across multiple files - Remove unused import ContentStandards from content_standards.py - Update Callable import to collections.abc in mcp_tools.py - Fix line length (E501) in server/base.py Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * feat: sync with ADCP 2.6 schema changes - Sync schemas from upstream adcontextprotocol.org - Consolidate pricing options (CpmAuction/CpmFixed -> CpmPricingOption, VcpmAuction/VcpmFixed -> VcpmPricingOption) - Consolidate PreviewRender (UrlPreviewRender/HtmlPreviewRender/BothPreviewRender -> unified PreviewRender) - Update type exports and aliases for backwards compatibility - Fix preview_cache.py to work with unified PreviewRender (no longer RootModel) - Update tests to reflect schema changes BREAKING CHANGE: CpmAuctionPricingOption, CpmFixedRatePricingOption, VcpmAuctionPricingOption, VcpmFixedRatePricingOption have been consolidated into CpmPricingOption and VcpmPricingOption respectively.

Renamed to model_summary() to follow Pydantic's naming convention (model_dump, model_dump_json, etc.) and avoid the collision. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * docs: add tests documenting version negotiation design Version negotiation is intentionally delegated to consumers. The SDK provides primitives (get_adcp_capabilities, TaskResult wrapping), not policy. Added TestVersionNegotiationDesign class with tests that serve as executable documentation for: - TaskResult error wrapping pattern - Capabilities response structure - Recommended version detection pattern - Recommended feature detection pattern Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * docs: update pricing option examples to current schema format Updated test fixtures and documentation examples from deprecated format: {"model": "cpm_fixed_rate", "is_fixed": true, "cpm": 5.50} To current unified CpmPricingOption schema format: { "pricing_model": "cpm", "pricing_option_id": "po-1", "currency": "USD", "fixed_price": 5.50 } The old format used separate types with is_fixed discriminator. The new schema uses optional fixed_price/floor_price fields to distinguish fixed vs auction pricing. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * feat: upgrade to ADCP 3.0.0-beta.1 schemas - Update ADCP_VERSION from 'latest' to '3.0.0-beta.1' - Sync schemas from https://adcontextprotocol.org/schemas/3.0.0-beta.1/ - Update generate_types.py to handle versioned schema paths (previously only handled /schemas/latest/, now handles /schemas/<version>/) - Regenerate Pydantic models from new schemas - All 518 tests pass - mypy passes with no issues Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * style: fix import sorting in _ergonomic.py Reorder imports to satisfy ruff I001 (isort) rules. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * ci: skip schema sync for pre-release versions Pre-release schema versions (alpha, beta, rc) may not be publicly accessible from CI environments. Skip the download/sync steps for these versions and rely on committed schemas instead. Validation steps (syntax check, import test, code generation tests) still run to ensure the committed schemas work correctly.
