aws_whoamiCurrent identity (account, ARN) + SSO token expiry countdown. Call this first.aws_login_startStart `aws sso login --no-browser --use-device-code`, returns a verification URL + short code and a `sessionId`. (`--use-device-code` is omitted on AWS CLI older than 2.22.0, where the device grant is already the default.)aws_login_completeBlock until the SSO subprocess finishes (you auth in your browser), returns the new identity.aws_refresh_if_expiring_soonCheck the cached SSO token and auto-start a refresh when < `thresholdMinutes` remain (default 10). One round-trip for "am I about to expire? if so, re-login."aws_session_setSet the default profile and/or region for the rest of this MCP session. "Switch to prod," "use us-west-2."aws_session_getShow the current session defaults and where each value came from (`session`/`env`/`default`).aws_session_clearRemove session profile/region overrides so env vars / defaults take over again. No args clears both.aws_list_profilesList profiles configured in `~/.aws/config` -- names, regions, and SSO metadata. Use before switching profiles or when an SSO error names one you haven't seen.aws_assume_roleCall STS AssumeRole with your current identity and stash the temp creds as a new profile (`mcp-<sessionName>`) in `~/.aws/credentials`. Use for cross-account access. The secret/session token stay on disk -- not returned to the model. Optional `timeoutMs` (default 120s) for slow SAML / `credential_p…aws_callRun any AWS API operation. `service: 's3api', operation: 'list-buckets'`, optional `params` (PascalCase JSON), optional `query` (JMESPath). Returns parsed JSON. Hand-written CLI commands (`s3 cp/ls/sync`, `logs tail`) and operations that stream their response to a file (`s3api get-object`, `bedrock…aws_paginateFetch one page of a paginated list/describe operation. Supports `query` too. Returns `nextToken`/`hasMore`; call again with the token to continue.aws_logs_tailFetch the newest CloudWatch Logs events for one log group (FilterLogEvents via `aws logs filter-log-events`), with `since`, `filterPattern` and stream-name filters; returns `{timestamp, logStreamName, message}` objects, oldest first. Bounded by `maxEvents` (default 500, max 10000): a busier window…- +16 more on the listing page
