Coverage by step

Manifests

What an agent can call

• A2A agent Pinecone at https://www.pinecone.io/mcp/, skills: Browse Pinecone marketing content
• API description https://pinecone.io/openapi.json (service-desc)
• llms.txt: Pinecone, 215 links
• robots.txt AI policy: no AI crawler tokens named; unlisted crawlers allowed on public paths (subpaths disallowed under User-agent: *)

Standards observed

• Agent2Agent Protocol https://pinecone.io/.well-known/agent-card.json
• llms.txt https://pinecone.io/llms.txt
• api-catalog: A Well-Known URI and Link Relation to Help Discovery of APIs https://pinecone.io/.well-known/api-catalog
• Markdown for Agents https://pinecone.io/

Cheapest next steps

1. Agentic Resource Discovery: a catalog at /.well-known/ard.json lets agents discover your APIs, MCP servers and data in one fetch (emerging spec — publish only if you run the underlying endpoints; generate via MCP template({"id": "ard", "domain": "pinecone.io"}))
2. AGENTS.md: instructions for coding agents working on or with the site
   Generate starter /AGENTS.md for pinecone.io

Agent pre-flight & practical readiness

Preferred mode: openapi (fallback a2a). Read the published API description and call those operations. Scraping HTML skips the interface the site already gave you.

Fetch: GET https://pinecone.io/openapi.json GET the API description and call the documented operations.

Practical readability: exa_parsable yes, markdown negotiation yes, render markdown_native, HTML quality high, first content at byte 0.

AI crawler posture: open_to_all · Assistant access: OpenAI allowed, Anthropic allowed, Google allowed, Perplexity allowed, Exa allowed.

Readiness subscores: reach 19/20, readability 30/30, capabilities 20/35, conformance 15/15, total 84/100, grade A+.

How the grade is made

+10 per lifecycle step with a standard observed, counting manifests that validate or that the probe rule for the standard recognises (a valid MCP server card counts for MCP; max 90); +3 per observed standard beyond the first two (max 15); conformance +15 (+10 with one manifest) minus 5 per agent-facing manifest with errors, never below 0 (security.txt is reported, not scored). Lifecycle grade: A+ >= 60, A >= 45, B >= 30, C >= 20, D >= 10. Strict 100-point composite (subscores.total_100 / subscores.grade_100): reach_and_policy (20) + readability (30) + capabilities (35) + conformance (15), where A+ >= 80, A >= 65, B >= 45, C >= 28, D >= 15. Errors are specification violations; warnings are best-practice gaps. Only public paths are fetched, without credentials, so standards that need a login (skipped in the probe) are not counted either way. The same report is the validate_manifest tool on the MCP server.
