….md (awslabs#4581) AWS removed aws___call_aws from the managed AWS MCP Server on 2026-08-31, but the migration guide still listed it as a live tool and told readers every action is reachable through it. Clients built from the guide broke with a hard-to-diagnose 'The call_aws tool has been removed' error. Remove it from the live tool table (replaced by a removal note), point API coverage at aws___run_script only, and add a call_aws->run_script porting example noting call_boto3 takes the PascalCase operation name and that a single-call run_script takes ~13-15s (so 10s client timeouts fail).

Issue
Fixes #4581.
Problem
src/aws-api-mcp-server/MIGRATION.mdstill listsaws___call_awsas a live tool on the AWS MCP Server and says every action is "reachable throughaws___call_awsandaws___run_script". AWS removedaws___call_awsfrom the managed server on 2026-08-31 (tools/callnow returnsThe call_aws tool has been removed, use another one.). Clients built from this guide break with a hard-to-diagnose error while the guide tells readers the tool is fine.Changes
aws___call_awsfrom the live tool table and added a dated removal note (deprecated 2026-07-15, removed 2026-08-31) pointing toaws___run_script.aws___run_scriptonly.call_aws→run_scriptporting example, with the two notes that trip up most ports:call_boto3takes the PascalCase operation name (GetSecretValue), not the CLI'sget-secret-value;run_scripttakes ~13–15s, so clients ported with a 10s timeout fail on every call.Docs-only change; no code paths touched.
