Conversation
Tutorial covering end-to-end setup of ToolHive as an authentication proxy for the AWS MCP Server on Kubernetes. Users register their OIDC provider with AWS IAM, create IAM roles with the aws-mcp permission model, configure MCPExternalAuthConfig with type: awsSts, and deploy an MCPRemoteProxy pointing to the AWS MCP Server endpoint. Also adds cross-references from existing token exchange and remote proxy docs so readers discover the AWS-specific auth path: - concepts/backend-auth: mention AWS STS in the federation section, add "Built-in AWS STS support" subsection - guides-k8s/token-exchange-k8s: link in Related information - guides-k8s/remote-mcp-proxy: tip admonition after token exchange section Fixes: #510
- Fix OIDC issuer placeholder: rename <YOUR_OIDC_ISSUER_HOST> to
<YOUR_OIDC_ISSUER>, clarify it excludes the https:// scheme and
must include path components (avoids doubled-scheme copy-paste
error and works for Okta/Keycloak issuers with paths)
- Clarify roleClaim vs claim: explain that roleClaim defaults to
"groups" when omitted, that the claim field under roleMappings
is a value to match (not a claim name), and show how to override
the claim name for other IdPs
- Remove misleading region suggestion: the AWS MCP Server endpoint
only exists in us-east-1
- Add Gateway API note and connect-clients cross-reference in Step 5
- Move role selection admonition from Step 2 to Step 3 where the
priority field first appears
- Add AWS CLI to prerequisites
- Replace stale "7 of 9 tools" with "most tools"
- Mention jq dependency alongside oauth2c at point of use
- Simplify line highlighting to {4,7}
- Remove "Optionally" from IAM cleanup
