Agent MCP Directory

Twilio: the 360 agent-readiness check

Twilio scores 85 of 100 on Ora's agent-readiness scan, a B, read 9 November 2026. Of the five surfaces an agent acts on, Ora found 4: an MCP server, a public API, OAuth, a command line. Live MCP, OpenAPI and OAuth in place; the registry entry is missing.

On 9 November 2026 the public site at twilio.com scored 85 of 100 on Ora's agent-readiness scan, a B, in Ora's Communication & Support category. Ora probes a site the way an agent would: it requests pages with the agents' own user agents, reads robots.txt, looks for the files agents read, and tries the API, MCP and payment surfaces. This check reads the act layer first, because that is what the directory records, then the door, what an agent can read, and whether the company is found and recommended. Ora's one-line summary: Twilio offers a strong OpenAPI spec and broad developer discoverability, but lacks declared OAuth scopes and scoped-permission documentation for agents.

What an agent can do

The surfaces an agent acts on: an API it can find and call, an MCP server, an agent card, OAuth metadata, a command line. This is the layer the directory records, so it comes first. 2 checks in this group do not apply to this site and are left out.

In the directory, Twilio has an open MCP server with tools listed at https://www.twilio.com/.well-known/mcp, 5 tools listed, no authentication; the connector run of 4 November 2026 is on the entry page. Ora's MCP server check for the same domain reads pass; the two look for different things, the directory for a server that answers a handshake and lists tools, Ora for a server it can find from the site.

The fixes worth most points

Ora attaches an estimate to each failing or partial check: how many points the site would gain by passing it. These are the 5 with the largest estimates for Twilio, with what Ora observed. The wording of each fix is Ora's; the 28 checks it runs on an MCP server are listed with their layer and tier.

  • Scoped permissions: fail, 0 of 5, about 2.9 points to gain. Ora saw: No declared OAuth scopes, security schemes, or scoped-permission documentation found
  • WebMCP support: fail, 0 of 5, about 2.9 points to gain. Ora saw: No WebMCP support detected - no document.modelContext / navigator.modelContext usage found (scanned 7 of 7 same-origin script bundle(s) for modelContext registrations)
  • ARD discovery: fail, 0 of 1, about 1.4 points to gain. Ora saw: No /.well-known/ard.json, no same-site rel="ard" link, and no legacy /.well-known/ai-catalog.json
  • Listed in MCP registries: fail, 0 of 1, about 1.4 points to gain. Ora saw: No verified entry in the official MCP Registry or on Smithery, and no npm or PyPI package of yours that runs as an MCP server. To pass,
  • Agent discovery file: fail, 0 of 2, about 1.1 points to gain. Ora saw: No agent discovery file found

Our read

Twilio has the most complete act layer of the first dozen companies read here. The MCP server completed a live handshake, twilio-com-public-web-mcp version 0.1.0 on protocol 2025-11-25, and is discoverable at the standard /.well-known/mcp path; an OpenAPI specification in YAML is published; OAuth authorization server metadata sits at support.twilio.com/mcp/oauth; the CLI is on npm and SDKs are in four registries. The 85 is held back by the newer checks: no declared OAuth scopes, no WebMCP registration in any of the seven script bundles Ora read, no agent discovery file and no entry in the official MCP Registry or on Smithery. The reading side is sound, with an llms.txt on the main domain and a complete Organization block, though robots.txt refuses the training crawlers and the heading hierarchy skips from H2 to H4. A registry entry is the cheapest point on this page.

Test your own surfaces

The scan above is free and needs no account: enter a domain at ora.ai and read the same four layers for your own site. For an MCP server, Ora scans the server URL itself and runs 28 of its 132 public checks on it, which is why it is the check this directory recommends; the reasons, the limits and the alternatives are on their own page. The command below runs the same audit from a terminal and exits with 1 under the score you set, so it can gate a deploy.
