AWS MCP Server tools 28

• aws_whoamiShow the current AWS identity (account, role ARN, user ID) plus SSO token status and time remaining. Use this first to verify auth before running other AWS operations. Returns a structured fix-it message if SSO is expired.
• aws_login_startStart an AWS SSO login via the device-code flow (no browser spawned from this process). Returns a verification URL and short code -- surface these to the user so they can open the URL in their own browser and paste the code. After they auth, call aws_login_complete with the returned sessionId to confirm completion.
• aws_login_completeBlock until the SSO login started by aws_login_start finishes (user completed auth in browser, or subprocess exited with error). Returns the new identity on success, or a structured error.
• aws_refresh_if_expiring_soonProactive SSO token check. If the cached token has fewer than `thresholdMinutes` left (default 10), this kicks off aws_login_start and returns the verification URL + code in one round-trip. If plenty of time remains, returns `status: 'ok'` with the minutes left. Use at the start of a multi-step AWS workflow to avoid mid-session expiry. `status: 'ok'` is a point-in-time reading of the cache, not a lease: nothing re-checks afterwards, so a token that lapses mid-workflow still surfaces as an sso_expired error from the next aws_call / aws_whoami. Raise `thresholdMinutes` to cover the expected length of the workflow rather than treating 'ok' as a guarantee.
• aws_session_setSet the default AWS profile and/or region for the rest of this MCP session. Subsequent calls to aws_whoami, aws_login_*, and other AWS tools will use these values unless they override explicitly. Use when the user says 'switch to prod', 'use us-west-2', 'look at the staging account', etc. Both params are optional; pass whichever changed. Returns the resulting session state.
• aws_session_getShow the current session's default AWS profile and region, and where each value came from ('session' = set by aws_session_set, 'env' = AWS_PROFILE/AWS_REGION env var, 'default' = built-in fallback). Useful for confirming state before running operations or debugging why a call hit the wrong account.
• aws_session_clearRemove session-set profile and/or region overrides so subsequent calls fall back to env vars / defaults. No args clears both. Pass `profile: true` or `region: true` to clear just one. Use when the user says 'go back to the default profile,' 'unset the region,' or 'reset session.'
• aws_callRun an arbitrary AWS API operation via the aws CLI. Use kebab-case service and operation names as in `aws help` (service='s3api', operation='list-buckets'). Pass params as a JSON object using the AWS API's PascalCase keys (e.g. {Bucket: 'foo'}); they go through --cli-input-json. Session profile/region (from aws_session_set) are used by default; override per-call when needed. Hand-written CLI commands (aws s3 cp/ls/sync, aws logs tail) and operations that stream their response to an output file (s3api get-object, bedrock-runtime invoke-model, bedrock-agentcore invoke-agent-runtime, lambda invoke) do not accept --cli-input-json and cannot run here -- use aws_lambda_invoke or aws_logs_tail where they exist, bedrock-runtime converse for text inference, otherwise your shell. Waiters work: operation 'wait instance-running'. Blob-typed members of params (KMS Plaintext, Kinesis Data, DynamoDB B) take base64 -- the server runs the CLI with --cli-binary-format base64 whatever your AWS config says. Returns parsed JSON output by default, plus the literal command that was run.
• aws_list_profilesList AWS profiles configured in ~/.aws/config. Returns profile name, region, and SSO metadata (start URL, region, session name) where set, plus an `isSso` flag. Use when the user hasn't named a profile, when they ask to switch profiles, or when an SSO-expired error mentions a profile you haven't seen.
• aws_paginateFetch one page of a paginated AWS list/describe operation. Identical to aws_call plus `maxItems` (page size) and `startingToken` (resume cursor). When `query` is supplied it is wrapped server-side as {NextToken, items: <query>} so pagination survives a projection that would otherwise drop NextToken; the handler unwraps `items` before returning. Returns the parsed response, a `nextToken` (null when the list is exhausted), and `hasMore`. Call again with the returned nextToken as startingToken until hasMore is false. Use this instead of aws_call for operations that might exceed the 5 MB stdout cap: list-objects-v2, describe-instances, describe-log-streams, list-roles, etc.
• aws_assume_roleCall STS AssumeRole and stash the returned temporary credentials as a named profile in the shared credentials file ($AWS_SHARED_CREDENTIALS_FILE when set, otherwise ~/.aws/credentials; the resolved path is returned as credentialsPath). Subsequent calls to aws_call / aws_whoami / aws_paginate can use profile='mcp-<sessionName>' (or your overridden targetProfile name). The raw secret key / session token are NOT returned to the caller — only the profile name, expiration, and assumed identity. Use for cross-account access: a source profile (your SSO identity) assumes a role in another account. Default timeout is 120s (raise via timeoutMs for slow SAML / credential_process setups on cold start).
• aws_logs_tailFetch the newest CloudWatch Logs events for one log group over the last `since` (default 10m), via FilterLogEvents ('aws logs filter-log-events'). Returns events oldest first as {timestamp (ISO 8601 UTC), logStreamName, message (verbatim)}; any of the three is null on an event that arrived without it, which is kept rather than dropped. At most `maxEvents` come back (default 500, max 10000); when the window held more, the OLDEST are dropped and `truncated` is true. On AWS CLI 2.35.8+ the read goes newest-first and stops once it has enough, so a busy group costs a page or two -- and a truncated result reports `totalEvents: null` because the rest was never read. Older CLIs read the whole window (exact `totalEvents`); narrow `since` or add `filterPattern` if a wide window times out. `logGroupName` takes a bare name or a log-group ARN in the call's region; an ARN is sent as logGroupIdentifier, so a source-account ARN works from a cross-account monitoring account (AWS CLI 2.9.15+). Does not stream: call again for newer events. eventId and ingestionTime are omitted -- use aws_call for them.
