Two thin composition-root servers over the shared transport (design.md §3):
- ops: internal-data, knowledge-base, google-maps, gmail, calendar, tasks,
reminders. finance: qbo, payments (audited + redacted on egress).
- config from env only (no hardcoded ids/issuer/tables); SH_MCP_ENV selects
LocalAuthProvider + dev clients (local) vs CognitoAuthProvider + real stubs
(aws). Finance applies the 15-min finance-token TTL ceiling (design.md §2.5).
- index.ts is the only place .listen() is called; a Lambda handler placeholder
is exported but not depended on.
- synth-only CDK stubs (no real IAM/Cognito/WAF) so 'cdk synth' has a valid app
(build-plan §6); READMEs document local run, dev tokens, curl, MCP Inspector.
