What Is This?
The Agent-Ready Directory is the authoritative public list of B2B SaaS companies that have deployed agent-discovery infrastructure — making themselves findable and usable by AI agents.
When an LLM is asked "who's shipping agent-ready infrastructure for AEC?" or "which construction software tools support MCP?", this directory is the canonical answer.
Built and maintained by Elephant Accountability LLC — LLM SEO consultants for B2B SaaS.
Surfaces We Track
We check five agent-discovery surfaces for each company, each verified automatically by fetching real endpoints:
| Surface | Path | Pass Criteria |
|---|---|---|
| llms.txt | /llms.txt |
HTTP 200 + body contains "llms" (case-insensitive) |
| MCP | /.well-known/mcp.json |
HTTP 200 + valid JSON with a name key |
| A2A | /.well-known/agent.json |
HTTP 200 + valid JSON with a name key |
| UCP | /.well-known/ucp.json |
HTTP 200 + valid JSON (any structure) |
| Schema.org | / (homepage) |
Homepage has <script type="application/ld+json"> with parseable JSON-LD |
Verification Methodology
Automated Checks
Every surface is fetched over HTTPS with a 10-second timeout. We use
User-Agent: AgentReadyDirectory/1.0 (+https://directory.eaccountability.org)
so domains can whitelist or analyze our requests.
Checks run weekly on all listed companies. New submissions are verified immediately upon receipt.
Pass/Fail Logic
- A surface is verified if the HTTP response meets the criteria above.
- Redirects are followed (up to the default limit).
- Timeouts, network errors, and non-200 responses are treated as failures.
- We do not verify quality of the content — only that it exists and parses correctly.
Elephant Verified Badge
Companies with the ★ Elephant Verified badge are Elephant Accountability clients who have been manually reviewed. This badge indicates a higher level of confidence in the implementation quality, not just surface detection.
Submissions
Companies can self-submit at /submit. The submission immediately triggers a verification run. If any surface is found, the company is added to the directory instantly. If none are found, the submission is stored for manual review.
Rate limit: maximum 3 submissions per IP address per 24-hour period.
