Pantheon: MCP server, CLI and agent surfaces
Sign-in required, tools not seen, not counted. No source names an endpoint for Pantheon; the connector's guess at mcp.pantheon.io answered 401 with OAuth metadata on 4 November 2026. Its tools can be listed only after a person authorizes a client, and this directory never signs in.
Fact sheet
| Company | Pantheon |
|---|---|
| Domain | pantheon.io |
| Category | Infrastructure (Ora leaderboard category) |
| MCP server | Sign-in required (OAuth without client registration) |
| Ora score | 61, grade C; Ora scanned the domain on 25 September 2026 and the cached score was read on 5 November 2026 from Ora's leaderboard (Ora's score page for pantheon.io, a vendor-published score) |
| Company found through | Ora's public leaderboard |
| Last verified | 4 November 2026 |
MCP server
| Endpoint | https://mcp.pantheon.io/mcp |
|---|---|
| How it was found | endpoint found by subdomain guess; it answered with a sign-in challenge and was not verified |
| Transport | streamable-http |
| HTTP status | 401 |
| Connected | 4 November 2026, 20:03 UTC |
| Handshake time | 1,116 ms over 1 attempt |
The endpoint answered the handshake with a sign-in challenge, so the tool list is not visible to this directory. It is not counted as an MCP server: a sign-in challenge is its own state, and the connector listed no tools.

Authentication
| Auth type | OAuth without client registration |
|---|---|
| What the challenge said | Bearer error="invalid_request", error_description="missing bearer token", resource_metadata="https://mcp.pantheon.io/.well-known/oauth-protected-resource" |
| Protected resource metadata | mcp.pantheon.io |
| Authorization server metadata | mcp.pantheon.io |
The sign-in route, step by step
- Request
https://mcp.pantheon.io/mcpwithout a token. It answers 401 and aWWW-Authenticateheader. - Read the OAuth metadata at
https://mcp.pantheon.io/.well-known/oauth-authorization-server. It lists no registration endpoint. - Register the client by hand in the company's developer settings, or present a client ID metadata document if the authorization server supports one.
- Authorize as a person, then retry the endpoint with the bearer token. The connector stops after step 2.
See OAuth for MCP: client ID metadata documents and dynamic registration for how each route works.
CLI
No CLI is on record for Pantheon. The directory checks a package only where a source names one, so this is a floor: a company can ship a command line that no source read for this edition mentions. See shipping a CLI agents can use.
