Calendly: the 360 agent-readiness check
Calendly scores 72 of 100 on Ora's agent-readiness scan, a B, read 9 November 2026. Of the five surfaces an agent acts on, Ora found 2: a public API, OAuth. A live MCP server, with neither a specification nor an SDK around it.
On 9 November 2026 the public site at calendly.com scored 72 of 100 on Ora's agent-readiness scan, a B, in Ora's Productivity 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: Calendly offers a published MCP server and passing access controls, but lacks a published OpenAPI specification for agents to discover its endpoints.

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, Calendly sign-in required, tools not seen, not counted; the connector run of 4 November 2026 is on the entry page. Ora's MCP server check for the same domain reads partial; 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 Calendly, 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.
- OpenAPI spec published: fail, 0 of 7, about 3.8 points to gain. Ora saw: No OpenAPI/Swagger specification found
- WebMCP support: fail, 0 of 5, about 2.7 points to gain. Ora saw: No WebMCP support detected - no document.modelContext / navigator.modelContext usage found (scanned 1 of 1 same-origin script bundle(s) for modelContext registrations)
- Developer resource discoverability: partial, 1 of 3, about 2.5 points to gain. Ora saw: In a search for your API docs, none of the 10 results is your official docs.

Our read
Calendly's act layer is live at the centre and empty at the edges. The MCP server at mcp.calendly.com answers and requires authentication, llms.txt on the developer host references it, OAuth authorization server metadata is on calendly.com and the REST documentation at developer.calendly.com scores 7 of 7. Around that Ora found no OpenAPI specification, no SDK package in any language registry and a CLI that is mentioned rather than published, about 6 points, and the one script bundle registers no WebMCP tool. Discovery is the weakest layer at 11 of 18: calendly.com ranks seventh for its own name, and in a search for its API documentation none of the ten results is the official site. The home page gives 9,717 characters at a 1.2 percent text ratio, and the Organization block lacks its description. A scheduling tool is the thing agents will be asked to use most; a specification and an SDK would make the server easier to reach than the 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.
