JS: migrated browser registration to navigator.modelContext.provideContext() per current WebMCP spec; legacy ai.tools.register() kept as fallback
JS: corrected tool field from parameters to inputSchema (WebMCP/Anthropic spec)
Discovery: added service-desc and service-doc Link relations alongside api-catalog and webmcp-manifest
Discovery: OAuth authorization-server and oauth-protected-resource now served on all sites (not WooCommerce-only) — explains WordPress nonce auth to agents
Discovery: HTML tags updated to include service-desc and service-doc
1.5.0
Added WooCommerce commerce agent discovery (active only when WooCommerce is installed):
OAuth Authorization Server metadata at /.well-known/oauth-authorization-server (RFC 8414)
OAuth Protected Resource metadata at /.well-known/oauth-protected-resource (RFC 9728)
Universal Commerce Protocol profile at /.well-known/ucp (ucp.dev)
Agentic Commerce Protocol discovery at /.well-known/acp.json (agenticcommerce.dev)
Added /wp-json/webmcp-bridge/v1/nonce endpoint — agents can fetch a fresh WP REST nonce for authenticated tool calls
Discovery endpoint now includes commerce URLs when WooCommerce is active
1.4.4
Added Content-Signal directives to robots.txt (contentsignals.org): ai-train=yes, search=yes, ai-input=yes — filterable via webmcp_bridge_content_signals hook
Added Vary: Accept header so nginx/CDN caches correctly serve Markdown for Agents requests separately from HTML responses
1.4.3
Fixed RFC 8288 Link discovery for cached sites: added tags in HTML via wp_head
Link tags are part of the cached HTML so agents find them even when nginx serves cached pages without running PHP
HTTP Link headers still added via wp_headers as secondary channel on cache misses
1.4.2
Fixed RFC 8288 Link headers: switched from send_headers action to wp_headers filter for reliable delivery through nginx/cache layers
Link headers now added to all pages (not just homepage) so agents can discover the API from any entry point
1.4.1
Fixed Agent Skills index: added sha256 digest field to each skill entry (required by v0.2.0 spec)
1.4.0
Added RFC 8288 Link response headers on homepage: advertises manifest, API catalog and MCP Server Card to agents
Added /.well-known/mcp/server-card.json (SEP-1649): MCP Server Card for agent discovery
Added /.well-known/api-catalog (RFC 9727): machine-readable API catalog including WebMCP and Mescio endpoints
Added /.well-known/agent-skills/index.json: Agent Skills discovery index listing all site capabilities
Added /wp-json/webmcp-bridge/v1/discovery: convenience endpoint listing all discovery URLs
All well-known endpoints include Mescio for Agents data automatically when plugin is active
