  • tools/resources/prompts listed in the card; SEP-2127 excludes primitives (list them live, or under a namespaced _meta key)
  • legacy /.well-known/mcp.json is still live and may shadow /.well-known/mcp/server-card.json in older scanners

What an agent can call

Standards observed

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": "prisma.io"}))
  2. AGENTS.md: instructions for coding agents working on or with the site
    Generate starter /AGENTS.md for prisma.io
    # Prisma for agents
    
    Prisma and what it offers to agents
    
    ## Read the data, not the HTML
    - Index: https://prisma.io/llms.txt
    - API description: https://prisma.io/openapi.json
    - Discovery catalog: https://prisma.io/.well-known/ard.json
    
    ## Calling
    - MCP server (Streamable HTTP): https://prisma.io/mcp
    - Rate limits and authentication: describe them here
    
    ## Conventions
    - How to cite or attribute content
    - What not to do (no scraping of /account/, no automated sign-ups, etc.)
    
    Contact: security@prisma.io
    
  3. api-catalog: A Well-Known URI and Link Relation to Help Discovery of APIs: an RFC 9727 linkset pointing at your OpenAPI description (conditional spec — publish only if you run the underlying endpoints; generate via MCP template({"id": "api-catalog-rfc9727", "domain": "prisma.io"}))

Agent pre-flight & practical readiness

Preferred mode: mcp (fallback agent_skills). Call the MCP endpoint at https://mcp.prisma.io/mcp first. Do not scrape the HTML when a tool can answer.

Fetch: POST https://mcp.prisma.io/mcp POST a JSON-RPC tools/list, or server/discover on the 2026-07-28 revision, before reading HTML.

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 20/20, readability 30/30, capabilities 23/35, conformance 10/15, total 83/100, 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.
