MCP Comparison
AWS CLI vs Google Cloud
Updated: April 16, 2026
Verdict
AWS MCP has the widest service coverage and AWS Labs maintenance. GCP MCP is community-maintained and focuses on core GCP services (Compute, BigQuery, GCS, Cloud Functions). If GCP is your primary cloud, GCP MCP does the job; AWS MCP is the more mature product because AWS is the older and bigger cloud.
Pick AWS CLI if...
- +Your stack runs on AWS, not GCP
- +You need the broadest service coverage available today
- +IAM role chaining and SSO already work in your org
- +You want vendor-backed maintenance from AWS Labs
- +You use AWS-native model services for inference
Pick Google Cloud if...
- +Your workloads run on GCP
- +You want BigQuery, Vertex AI, and GCS in one tool
- +Your auth is application default credentials
- +You prefer GCP IAM semantics
- +Your data lives in BigQuery for analytics

Frequently asked questions
Which MCP server is faster to set up, AWS MCP or GCP MCP?
AWS MCP typically installs via a single npm or pip command and asks for IAM credentials or SSO. GCP MCP needs application default credentials. Expect 2-5 minutes for either once credentials are ready. If you already have IAM configured, AWS MCP wins by a minute or two.
Can I run AWS MCP and GCP MCP side by side in the same Claude client?
Yes. Claude Desktop, Cursor, and Claude Code all accept multiple MCP servers in the same config file. Each runs in its own process and exposes a distinct tool namespace, so there are no naming collisions. Memory usage is additive; budget roughly 40-80 MB per server.
How do AWS MCP and GCP MCP compare on cost?
AWS MCP is free server, AWS usage billed separately. GCP MCP is free server, GCP usage billed separately. Most of the real spend is on the underlying service, not the MCP server itself; the server is almost always free. Budget based on query volume at the backend, not the MCP layer.
Is AWS MCP or GCP MCP more production-ready?
AWS MCP is maintained by AWS Labs, which tends to mean faster fixes. GCP MCP is community-maintained too; same diligence applies. For critical workloads, pick the vendor-backed option or pin a specific version.
What authentication does each server need?
AWS MCP authenticates with IAM credentials or SSO. GCP MCP uses application default credentials. Store secrets in a password manager or your shell's keychain and inject them via environment variables; never commit them to the MCP config file, which is often synced across machines.
Which one should I pick first if I am just starting with MCP?
Start with whichever backend you already pay for or use daily. If you do not use either yet, both require a paid account; pick based on the service you plan to use most. You can always add the second one later without disrupting the first.
