Generated by API Evangelist on 2026-09-14 from this repository's own artifacts and live probes.
Method: generated. Glacier Bancorp does not publish an llms.txt of its own — https://www.glacierbank.com/llms.txt
and https://glacierbancorp.com/llms.txt both return HTTP 404.

## What an agent can actually reach

- [OpenID Connect discovery document](https://connect.glacierbank.com/.well-known/openid-configuration): HTTP 200, application/json. Issuer `https://connect.glacierbank.com/a/consumer/api/v0/oidc`. 116 OAuth scopes, PKCE (S256), PAR, DPoP, token exchange, private_key_jwt, introspection and revocation endpoints.
- [JWKS](https://connect.glacierbank.com/a/consumer/api/v0/oidc/jwks): HTTP 200, application/jwk-set+json.
- Nothing else. There is no public REST, GraphQL, gRPC, SOAP, MCP or A2A surface on any Glacier host.

## What this is, and whose it is

The tenant runs on Jack Henry's Banno Digital Toolkit. Every endpoint (issuer, authorization, token,
userinfo, jwks, introspection, revocation, PAR, logout) is on connect.glacierbank.com, a host Glacier
controls, so the deployment is Glacier's. The scope and claim vocabulary is Jack Henry's
(`https://api.banno.com/consumer/auth/*`, `https://jackhenry.com/*`), so the contract is vendor-authored.
No Jack Henry specification has been copied into this repository.

Client credentials are provisioned out of band: the discovery document advertises no
`registration_endpoint`, so onboarding is not self-service.
