Reference: references/aws-mcp-profiles.md
List profiles with aws configure list-profiles. Read only these non-secret settings with aws configure get <key> --profile <profile>: sso_session, sso_start_url, sso_region, sso_account_id, sso_role_name, role_arn, source_profile, region, granted_sso_account_id, granted_sso_role_name. A missing setting is normal. Never retrieve access keys, session tokens, raw config files or credential caches, or execute credential_process to inspect its output. Let the AWS CLI handle authentication for the selected profile.
The AWS CLI continues to use its native credential chain, including credential_process. Keep the SSO, Granted and role-chain authentication setup guidance in references/aws-mcp-profiles.md.
For TTL, use only a profile-specific expiration timestamp the user has shared without credentials. Otherwise display unknown; successful authentication does not establish an expiry time. Parse MCP config files locally and return only server names, paths, AWS_PROFILE and AWS_REGION, since other fields can contain secrets. Do not print entire config files or diffs of unrelated fields.
When invoked with no arguments, ask before proceeding:
Q1 — Mode?
What do you need?
1. discover — list AWS profiles with type, account ID, env tag, and expiry when shared
2. status — show configured MCP profiles and check current authentication
3. switch — update MCP config files to use a different profile
4. login — authenticate and refresh credentials for a specific profile
5. org-scan — list all AWS Organization accounts and cross-reference with configured profiles
Enter 1–5 or mode name:Q2 — Mode-specific follow-up (one question, after mode is selected):
Any filters? (e.g. --expired to show only expired, --type sso, --env prod) — or press enter to list all:aws configure list-profiles, then ask: Which profile should MCP servers switch to?aws configure list-profiles, then ask: Which profile needs authentication?Which management account profile has organizations:ListAccounts permission? (default: current profile):Then proceed into the relevant mode below.
List profiles and output a classified profile table with TTL where shared expiration metadata is available.
aws-profile discover [--type sso|assume-role|granted|static] [--env prod|staging|dev] [--account <id>] [--chain] [--expired]Output:
Profile Type Account ID Env Tag Permission Set Expires TTL
prod-platform-eu sso 123456789 prod PowerUser 14:32 UTC 47m ✓
staging-assume assume-role 456789123 staging - 13:58 UTC 13m ⚠
dev-sandbox granted 987654321 dev Developer 09:00 UTC EXPIRED ✗
security unknown 890123456 - - unknown unknownThe timestamp examples above assume the user supplied profile-specific expiry metadata. Without it, show unknown in both expiry columns.
Steps:
Run aws configure list-profiles, then query only the metadata keys in Credential boundary. Classify each profile by the settings present:
sso_session or sso_start_url presentrole_arn + source_profilegranted_sso_account_id or granted_sso_role_name present; an assume binary alone does not classify every profileunknown; do not retrieve a key to classify itCalculate TTL only from shared expiration metadata for that profile. Do not read credential caches. Apply traffic-light TTL only when a timestamp is known:
Read ~/.aws-profile-tags.yaml for env tags. If the file does not exist, generate a starter file:
# ~/.aws-profile-tags.yaml — edit to correct heuristic guesses
prod-platform-eu: prod # detected: name contains 'prod'
staging-assume: staging # detected: name contains 'stag'
dev-sandbox: dev # detected: name contains 'dev'
security: shared-services # detected: name contains 'security'Print: Generated ~/.aws-profile-tags.yaml — review and correct environment tags.
Apply filters if flags provided. For --expired, list confirmed expired entries and report profiles with unknown TTL separately; unknown does not mean expired or healthy.
With --chain — show full role assumption chain for assumed-role profiles:
staging-assume role chain:
dev-sso (identity: 111111111)
└── assume → security-role (222222222)
└── assume → staging-platform (456789123) ← this profileFollow source_profile → role_arn links recursively with the metadata lookups above.
Reference: references/aws-mcp-profiles.md → Profile Type Detection, Credential Lifecycle
Show which profile each configured MCP server uses, authentication status and known credential TTL. Report refresh behaviour only when the configured method is known.
Note: MCP config identifies the intended profile; it does not prove which credentials an already-running server holds. Do not inspect credential caches or assume the agent's shell environment matches the server's.
aws-profile status [--watch] [--all-hosts]Output:
Profile in MCP configs: prod-platform-eu
Type: SSO | Account: 123456789 | Permission: PowerUser
Authentication: valid (AWS STS check)
Token expires: unknown (no shared expiration metadata)
MCP Servers:
eks-prod-eu ~/.vscode/mcp.json AWS_PROFILE TTL unknown
cloudwatch ~/.claude/settings.json AWS_PROFILE TTL unknown
eks-prod-us .vscode/mcp.json AWS_PROFILE TTL unknownSteps:
~/.vscode/mcp.json, ~/.claude/settings.json, and .vscode/mcp.json (if present in cwd), using local parsing.aws sts get-caller-identity --profile <profile> to check authentication; report errors without treating every failure as an expired token. Report TTL from shared metadata or unknown.AWS_PROFILE alone does not establish whether a particular server's SDK refreshes credentials; report that as unverified unless checked.--watch: re-run every 60 seconds. Apply TTL warnings only to known timestamps. Report authentication failures separately.Patch AWS_PROFILE (and AWS_REGION if --region provided) in MCP server config files. Requires --confirm for any profile tagged prod or whose name contains prod or production.
aws-profile switch <profile> [--scope global|workspace] [--server <name>] [--env <tag>] [--region <region>] [--confirm]Examples:
aws-profile switch prod-platform-eu --scope workspace --confirm
aws-profile switch dev-sandbox --scope global
aws-profile switch staging-assume --server eks-staging
aws-profile switch --env prod --confirmPre-condition: If ~/.aws-profile-tags.yaml does not exist, run aws-profile discover first to generate it.
Steps:
Resolve target profile:
--env <tag>: look up the profile in ~/.aws-profile-tags.yaml that matches the tag — this selects which profile to switch to, not which servers to patch. Error if multiple profiles share the tag — require explicit profile name.Safety check — if profile name contains prod or production or is tagged prod in ~/.aws-profile-tags.yaml:
⚠ WARNING: Switching to prod-platform-eu (tagged: prod, Account: 123456789).
MCP operations will run against production.
Pass --confirm to proceed.Halt without --confirm.
Determine target files by --scope:
global (default): ~/.vscode/mcp.json + ~/.claude/settings.jsonworkspace: .vscode/mcp.json in current directory only--server <name>: patch only that named entry, searching all scope files regardless of --scope (overrides scope)For each matched server entry, update env.AWS_PROFILE to the new profile. If --region provided, also update env.AWS_REGION and any --region arg in the args array.

Detect the profile type and emit the correct authentication command. After successful login, run status automatically.
aws-profile login <profile>Steps:
Query the allowed metadata keys for the selected profile. If the method is unknown, ask which authentication method the user configured instead of inspecting credentials.
Emit and explain the auth command:
SSO:
aws sso login --profile prod-platform-eu
This opens a browser for SSO authentication. After approval, your token
is cached in ~/.aws/sso/cache/ (TTL: 8–12h, org-configured).Granted:
assume prod-platform-eu
Granted will authenticate via SSO and cache credentials.
If prompted for duration, 4h is a reasonable default for a workday session.Assumed role:
The source profile 'dev-sso' must be authenticated first:
aws sso login --profile dev-sso
Then validate the role assumption:
aws sts get-caller-identity --profile staging-assumeStatic:
⚠ Static credentials do not have a login flow — they are long-lived and do not expire cleanly.
Recommendation: Rotate this profile to AWS SSO (IAM Identity Center).
See: references/aws-mcp-profiles.md → Auth FlowsAfter the user completes login, check the selected profile with aws sts get-caller-identity --profile <profile>. Report TTL as unknown unless the user shared an expiration timestamp; a successful STS check does not prove a green (>30 min) TTL.

List all accounts in the AWS Organization and cross-reference with configured profiles. Requires organizations:ListAccounts permission — available only from the management account or a delegated admin account.
aws-profile org-scan [--profile <mgmt-profile>] [--generate-profiles]Output:
AWS Organization accounts (via profile: org-management):
Account ID Account Name Env Tag Profiles configured
123456789 prod-platform prod ✓ prod-platform-eu, prod-platform-us
456789123 staging staging ✓ staging-assume
789012345 dev-sandbox-1 dev ✓ dev-sandbox
890123456 security-tooling - ✗ NO PROFILE — add to ~/.aws/config
901234567 shared-services - ✗ NO PROFILE — add to ~/.aws/config
2 accounts have no profile configured.
Run with --generate-profiles to emit ~/.aws/config stanzas for them.With --generate-profiles — select an existing SSO template profile and read its allowed metadata. Reuse its sso_session reference when present; the start URL and SSO region live in that existing session section and do not need to be copied into each new profile.
Session-based template (sso_session = platform):
# Add to ~/.aws/config; reuse the existing [sso-session platform] section.
# Replace ROLE_NAME with an authorized permission set for each account.
[profile security-tooling]
sso_session = platform
sso_account_id = 890123456
sso_role_name = ROLE_NAME
region = eu-west-1
[profile shared-services]
sso_session = platform
sso_account_id = 901234567
sso_role_name = ROLE_NAME
region = eu-west-1Legacy template (no sso_session): copy the template's profile-scoped sso_start_url and sso_region using the allowed lookups. For example:
[profile security-tooling]
sso_start_url = https://myorg.awsapps.com/start
sso_region = eu-west-1
sso_account_id = 890123456
sso_role_name = ROLE_NAME
region = eu-west-1Emit the corresponding form for each missing account. Keep an existing session definition unchanged. If a legacy template lacks either required SSO setting, ask for it instead of inventing a URL or region. Confirm the permission set per account. For a Granted template, retain its supported credential_process setup from references/aws-mcp-profiles.md; do not add a Granted dependency to a native AWS CLI template.
Steps:
aws organizations list-accounts --profile <mgmt-profile> --output json
If --profile is omitted, let the AWS CLI use its configured credential chain.sso_account_id metadata for listed profiles or call aws sts get-caller-identity --profile <p> to resolve.~/.aws-profile-tags.yaml for env tags.--generate-profiles: select an SSO template and read sso_session first. When it is present, generate new profiles referencing that same session. Otherwise, read the legacy template's sso_start_url and sso_region individually and require both before generating profiles. Use the supplied target account IDs and confirmed permission sets; never inspect a credential cache.Note: organizations:ListAccounts requires management account access. Most platform engineers work from member accounts and will not have this permission. This mode is intended for platform leads and account vending workflows.
