The AI Catalog Standard is the publishing half of Agentic Resource Discovery (ARD): a JSON manifest listing the agentic resources a domain offers — MCP servers, agent cards, skills, APIs — each typed by media type and identified by a domain-anchored urn:air: URN. Two verdicts are recorded: a structural grade against the data model, and the result of the ARD project''s own conformance CLI run against this exact body. Provider-published by construction — served from the provider''s own host; nothing here is derived or generated.' discovery: path: /.well-known/ai-catalog.json canonical: false predecessor_only: true attempts: - path: /.well-known/ard.json http_status: 404 - path: /.well-known/ai-catalog.json http_status: 200 host: zapier.com conformance: spec: AI Catalog 1.0 / ARD v0.91 grade: near-conformant spec_version_declared: '1.0' hard_failures: [] soft_gaps: - content-type-not-ai-catalog-json - host-identifier-not-did-web official_tool: tool: ARD conformance-test v0.9.1 (ards-project/ard-spec) status: FAIL critical_errors: 4 errors: - 'ArdManifest validation failed: [''https://zapier.com/.well-known/agent-skills/zapier-mcp/SKILL.md'', ''https://zapier.com/.well-known/agent-skills/zapier-sdk/SKILL.md'', ''https://zapier.com/.well-known/agent-skills/zapier-embed-mcp/SKILL.md'', ''https://zapier.com/.well-known/agent-skills/zapier-platform-cli/SKILL.md''] is not of type ''string'', ''number'', ''boolean'', ''null'' at path ''entries.7.metadata.skills''' - '[Zapier SDK (TypeScript)] ArdEntry validation failed: [''@zapier/zapier-sdk'', ''@zapier/zapier-sdk-cli'', ''@zapier/zapier-sdk-core'', ''@zapier/zapier-sdk-mcp''] is not of type ''string'', ''number'', ''boolean'', ''null'' at path ''metadata.npmPackages''' - '[Zapier Platform CLI] ArdEntry validation failed: [''zapier-platform-cli'', ''zapier-platform-core''] is not of type ''string'', ''number'', ''boolean'', ''null'' at path ''metadata.npmPackages''' - '[Zapier Agent Skills] ArdEntry validation failed: [''https://zapier.com/.well-known/agent-skills/zapier-mcp/SKILL.md'', ''https://zapier.com/.well-known/agent-skills/zapier-sdk/SKILL.md'', ''https://zapier.com/.well-known/agent-skills/zapier-embed-mcp/SKILL.md'', ''https://zapier.com/.well-known/agent-skills/zapier-platform-cli/SKILL.md''] is not of type ''string'', ''number'', ''boolean'', ''null'' at path ''metadata.skills''' warnings: - '[Zapier Public API Reference] Media type ''text/html'' is not one of standard discovery types: [''application/ai-catalog+json'', ''application/agent-card+json'', ''application/a2a-agent-card+json'', ''application/mcp-server-card+json'', ''application/agent-skills+zip'', ''application/agent-skills+gzip'', ''text/markdown; profile="urn:air:agent-skills"'', ''application/ai-registry'', ''application/ai-registry+json''].' - '[Zapier SDK (TypeScript)] Media type ''text/markdown'' is based on standard discovery type ''text/markdown'' but has missing required parameters: profile="urn:air:agent-skills".' - '[Zapier Platform CLI] Media type ''text/markdown'' is based on standard discovery type ''text/markdown'' but has missing required parameters: profile="urn:air:agent-skills".' - '[Powered by Zapier (embedded MCP + Workflow API)] Media type ''text/markdown'' is based on standard discovery type ''text/markdown'' but has missing required parameters: profile="urn:air:agent-skills".' - '[Install Zapier (router)] Media type ''text/markdown'' is based on standard discovery type ''text/markdown'' but has missing required parameters: profile="urn:air:agent-skills".' - '[AGENTS.md (agent guide)] Media type ''text/markdown'' is based on standard discovery type ''text/markdown'' but has missing required parameters: profile="urn:air:agent-skills".' - '[Agent auth guide (auth.md)] Media type ''text/markdown'' is based on standard discovery type ''text/markdown'' but has missing required parameters: profile="urn:air:agent-skills".' - '[Zapier root map (llms.txt)] Media type ''text/plain'' is not one of standard discovery types: [''application/ai-catalog+json'', ''application/agent-card+json'', ''application/a2a-agent-card+json'', ''application/mcp-server-card+json'', ''application/agent-skills+zip'', ''application/agent-skills+gzip'', ''text/markdown; profile="urn:air:agent-skills"'', ''application/ai-registry'', ''application/ai-registry+json''].' - '[Zapier app catalog] Media type ''text/html'' is not one of standard discovery types: [''application/ai-catalog+json'', ''application/agent-card+json'', ''application/a2a-agent-card+json'', ''application/mcp-server-card+json'', ''application/agent-skills+zip'', ''application/agent-skills+gzip'', ''text/markdown; profile="urn:air:agent-skills"'', ''application/ai-registry'', ''application/ai-registry+json''].' informational: - '[Zapier Web Tools (WebMCP)] Media type ''application/json'' is a valid application extension media type.
