nable MCP server

Read from the package source without running it. The installed server may list more.

• acknowledge_anomaly

  Mark an anomaly as acknowledged (dismissed). It will no longer appear in active anomalies.

• audit_aws_waste

  Deep AWS waste audit: scans EC2, EBS, RDS, Lambda, NAT Gateways, CloudWatch Logs, S3, and CloudTrail for waste. Returns findings sorted by monthly savings.

• audit_azure_reservation_scope

  Find Azure reservations locked to one subscription while a sibling subscription pays full price for the same capacity.

• audit_cloudwatch_logs_ia_opportunities

  Finds CloudWatch Log groups to migrate to Infrequent Access class. IA cuts ingestion cost 50% ($0.075 to $0.0375/GB). Candidates: groups older than 30 days with >1 GB/month still on STANDARD. Note: IA does not support metric filters or subscription filters.

• audit_cloudwatch_metric_cardinality

  Audits CloudWatch custom metric cardinality. Custom metrics above the 10,000 free-tier threshold cost $0.30/metric/month. High-cardinality dimensions like pod_id or request_id can cause thousands of metrics per microservice.

• audit_cloudwatch_orphaned_alarms

  Finds CloudWatch alarms on deleted resources. Standard alarms cost $0.10/month, composite $0.30/month. Terminated instances and deleted queues leave alarms stuck in INSUFFICIENT_DATA indefinitely.

• audit_duplicate_spend

  Find places where you're paying for the same capability through two different services or providers at once, the kind of waste a plain cost breakdown never surfaces because every line item looks legitimate on its own. Covers three patterns: multiple LLM inference paths active at the same time (e.g. AWS Bedrock Claude AND a direct Anthropic API key), multiple managed search/retrieval services (Kend

• audit_ebs_snapshot_replication

  Audits cross-region EBS snapshot replication for waste. Replicated snapshots cost $0.05/GB-month in each region. Finds orphaned copies (source volume deleted), excessive copies (more than 3 regions), and old copies where a newer copy exists.

• audit_efs_cross_az_mounts

  Finds EC2 instances mounting EFS from a different AZ. Cross-AZ mounts cost $0.02/GB in hidden transfer charges. Fix by adding a mount target per AZ.

• audit_nlb_cross_zone_costs

  Finds NLBs with cross-zone load balancing enabled. Cross-zone LB charges $0.01/GB for cross-AZ traffic. Safe to disable when AZs have equal capacity.

• audit_public_ipv4_addresses

  Audits public IPv4 addresses across AWS. Since Feb 2024, AWS charges $3.60/month per IP including stopped instances. Finds unattached Elastic IPs and IPs on stopped instances with release recommendations.

  Audits RDS manual snapshots for waste. Manual snapshots never auto-expire and cost $0.095/GB-month. Finds orphaned snapshots (source DB deleted) and old snapshots past the retention threshold.

• audit_s3_intelligent_tiering

  Finds S3 buckets using Intelligent-Tiering where the monitoring fee exceeds savings. IT costs $0.0025/1,000 objects, making it more expensive than S3 Standard for objects smaller than 128KB.

• audit_s3_transfer_accelerationwrite action

  Finds S3 buckets with Transfer Acceleration enabled that won't benefit. TA adds $0.04-0.08/GB and is often forgotten. Flags buckets as waste if volume is under 1 GB/month, bucket is in us-east-1, or it is behind CloudFront. Returns a CLI disable command for each flagged bucket.

• audit_spot_diversification

  Audits ASGs using spot for instance type diversification. ASGs with fewer than 3 types are HIGH_RISK. Best practice: 5+ types with capacity-optimized allocation to avoid correlated interruptions.

  Scan Terraform state for resources missing required tags. Runs `terraform show -json` in tf_dir (or reads state_path directly). Required tags configured via FINOPS_REQUIRED_TAGS env var (comma-separated, default: team,environment,service).

• audit_textract_environment_waste

  Analyzes Textract spend by environment to find non-production API calls. Textract charges per page, QA and staging environments often call it unnecessarily. Identifies which Lambda functions or services are calling Textract in non-prod and estimates the monthly waste.

• benchmark_costs

  Compare this account's spend profile against anonymised peer group medians.

• check_budget_status

  Check current spend against budgets. Shows how much has been spent, what's remaining, and whether any budgets are in warning or exceeded status.
