Q: Which AI agent discovery manifests and crawler policies does mcp.hubspot.com publish?

mcp.hubspot.com publishes 2 observed agentic-web standards (OAuth Protected Resource and Authorization Server Metadata (as used for agent authorization), Model Context Protocol). Preferred agent routing mode: mcp.

C Manifest validity: 0 manifests published (0 errors, 4 warnings) · Surface score 20 (coverage 20 + breadth 0 + conformance 0). 2 standards observed across 2 of 9 steps; 0 manifests present, 0 errors, 4 warnings. Checked 2026-10-25 23:47:04 UTC. This grades the agent-facing files published at mcp.hubspot.com, not the organisation's products.

What an agent can call

MCP endpoint https://mcp.hubspot.com (streamable-http) — from /.well-known/oauth-protected-resource
robots.txt AI policy: no AI crawler tokens named; unlisted crawlers allowed on public paths (subpaths disallowed under User-agent: *)
OAuth protected resource https://mcp.hubspot.com, authorization servers: https://mcp.hubspot.com

Short notes an agent should know before using the site: what it is for, who runs it, how to cite it.

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": "mcp.hubspot.com"}))

Agent pre-flight & practical readiness

Preferred mode: mcp. Call the MCP endpoint at https://mcp.hubspot.com first. Do not scrape the HTML when a tool can answer.

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

Practical readability: exa_parsable no, markdown negotiation no, render none, HTML quality none.

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

Readiness subscores: reach 20/20, readability 0/30, capabilities 14/35, conformance 0/15, total 34/100, grade C.

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.
