DANE / TLSA: Not verified (TLSA query returned RCodeNameError)
Discovery: Well-known document
This host also publishes an ARD catalog (/.well-known/ai-catalog.json) declaring 6 resources. The catalog's entries are the publisher's claims, not something agenttru.st verified.
AI use policy: Search: yesAI input: yesAI training: yes

What this site's robots.txt says about how AI may use its content. Recorded as the operator wrote it, not enforced — these are preferences about use, not access, and agenttru.st only reads the agent's own discovery documents.
AI-facing documents: Publishes /llms.txt — “Agentrail · See how AI agents use your product” a curated map of the site's content for language models

Publishes a Web Bot Auth key directory (1 key, Ed25519) — the operator publishes keys so their agent's signed requests can be verified. agenttru.st recorded that the directory exists; it has not verified a signature.

Fetched from this host during verification. Neither document is how this agent was discovered.

What its catalog declares

From the ARD catalog this host publishes at /.well-known/ai-catalog.json. The operator controls every entry; agenttru.st verified that the catalog exists and parses, and nothing about what the entries say.

Agentrail MCP server

mcp-server-cardtrust manifest

Agentrail itself, at https://mcp.agentrail.co/mcp (Streamable HTTP): workspaces, the leaderboard, simulations, agent readiness, competitors, topics, preference prompts, evaluations, feedback and the Brand Vault. OAuth 2.1 through WorkOS; the client registers itself and a person approves once. Read-only tools at /mcp/readonly.

https://www.agentrail.co/.well-known/mcp/product-server-card.json

Agentrail newsletter MCP server

mcp-server-cardtrust manifest

This site's MCP server, not the product (Streamable HTTP, no auth): record an email for the Field notes newsletter, check a spot, read the count and list the trails.

https://www.agentrail.co/.well-known/mcp/server-card.json

Agentrail agent

a2a-agent-cardtrust manifest

A2A agent (JSON-RPC, A2A 1.0, no auth) that records an email for a user and reports their spot.

https://www.agentrail.co/.well-known/agent-card.json

Agentrail newsletter signup skill

agent-skills+mdtrust manifest

A SKILL.md that teaches any agent to subscribe a user to the Field notes newsletter and check their spot.

https://www.agentrail.co/skills/agentrail-waitlist/SKILL.md

Agentrail public API

openapitrust manifest

OpenAPI for every public, no-auth route: the agent readiness API (leaderboard, scans, journeys) and the newsletter signup API.

https://www.agentrail.co/openapi.json

Agentrail API

openapitrust manifest

The whole Agentrail API, workspace routes included. Workspace routes take a token from WorkOS Agent Registration that a person claims once (https://api.agentrail.co/auth.md); the MCP server is the simpler way in.
