cloudprice-mcp

An MCP server that lets Claude, GitHub Copilot, Cursor, Windsurf, Cline, Continue, Zed — or any MCP-compatible AI — compare cloud pricing across AWS, Azure, GCP, and OCI in real time. 10 tools covering compute, block storage, object storage, managed Postgres, egress (internet + inter-region), Multi-AZ workloads, snapshots with realistic incremental modeling, and Reserved Instance / Savings Plan discounts. OCI Always Free tier (4 OCPU compute, 20 GB object storage, 10 TB egress) surfaced explicitly.

One-line install configures every AI client you have: pip install cloudprice-mcp && cloudprice-mcp setup — auto-detects Claude Desktop, GitHub Copilot Agent Mode, Cursor, Windsurf, Cline, Continue.dev, and Zed, then asks Y/N before writing each config.

Ask things like:

"How much does a 4 vCPU / 16 GB Linux VM cost across AWS, Azure, and GCP in us-east?"

"I have a 3-tier deployment: 8 web (4/16), 12 app (8/32), 4 DB (16/64), each with a 200 GB SSD OS disk, plus 5 TB SSD shared and 50 TB HDD bulk. Compare AWS vs Azure vs GCP monthly cost."

"What does an EC2 t3.xlarge cost per month?"

Claude calls the right tool, you get a clean answer with per-row + per-cloud + combined totals. No console-clicking. No tab-switching between three pricing calculators.

Install

Recommended (auto-config):

pip install cloudprice-mcp
cloudprice-mcp setup     # auto-configures every detected MCP client, asks Y/N before writing

Then fully restart whichever clients were configured. 10 tools appear in each. Done.

Trust spectrum:

Command	When to use
cloudprice-mcp setup	Default — detects every installed client, shows the plan, asks Y/N once
cloudprice-mcp setup --yes	Skip prompt (CI / scripts)
cloudprice-mcp setup --client copilot	Configure a specific client (repeatable: --client copilot --client cursor)
cloudprice-mcp setup --all	Configure every known client even if not detected
cloudprice-mcp setup --force	Refresh existing entries — useful after upgrade or moving Python
cloudprice-mcp setup --dry-run	Show per-client diffs without writing
cloudprice-mcp setup --print-config	Emit per-client JSON to stdout for manual paste
cloudprice-mcp setup --list-clients	Detection table — which clients are known + installed on this system
Manual edit	Don't trust running new tools — see INSTALL.md per-client sections

If something doesn't work, run:

cloudprice-mcp doctor

Tools exposed

Single-spec lookups (v0.1)

Tool	What it does
get_aws_price	Look up an EC2 instance type → vCPUs, memory, hourly + monthly USD (us-east-1)
get_azure_price	Look up an Azure VM size → vCPUs, memory, hourly + monthly USD (eastus)
get_gcp_price	Look up a GCP Compute Engine machine type → vCPUs, memory, hourly + monthly USD (us-east1)
compare_clouds	Given a target spec (vCPUs + GB), return the cheapest matching SKU across AWS / Azure / GCP / OCI, sorted by monthly cost, with savings summary

Bulk + workload compare (v0.2)

Tool	What it does
compare_compute_inventory	Bulk-compare a list of compute workloads (each with vCPUs / memory / quantity / hours / optional OS disk) across all 4 clouds. Returns per-row matches, per-cloud totals, cheapest cloud.
compare_storage_inventory	Bulk-compare a list of block-storage volumes (each with capacity / disk type / quantity) across all 4 clouds.
compare_workload	Combined compute + block storage in one call. Mirrors a two-sheet sizing workbook (compute BoM + storage BoM). Optional commitment overlay applies 1-year (30%) or 3-year (50%) compute discount.

Object storage + managed Postgres (v0.3)

Tool	What it does
compare_object_storage	Bulk-compare object-storage buckets across AWS S3 / Azure Blob / GCP Cloud Storage / OCI Object Storage. Each row specifies capacity_gb + tier (hot / cool / archive). OCI Always Free 20 GB tier surfaced explicitly — capacity ≤ 20 GB on OCI hot tier returns $0/mo.
compare_postgres_database	Bulk-compare managed PostgreSQL pricing across AWS RDS / Azure Database for PostgreSQL / GCP Cloud SQL / OCI Database with PostgreSQL. Each row specifies vCPUs / memory / storage_gb. Storage cost is calculated separately from compute.

Egress + Multi-AZ + better snapshots (v0.5, NEW)

Tool / Feature	What it does
compare_egress	Compare data-transfer costs across all 4 clouds. Two directions: out_to_internet (tiered pricing with free-tier credits — AWS/Azure 100 GB, OCI 10 TB) and inter_region (cross-region within the same cloud). At 50 TB/month internet egress, OCI is ~12× cheaper than the hyperscalers — a real moat for content/CDN workloads.
compare_workload multi_az: true	New flag doubles compute totals on every cloud to model Multi-AZ / HA deployments (sync replicas across two zones). Storage stays at 1× because object/block storage is usually cross-AZ at base price.
snapshot_incremental_factor	New per-row field on storage and OS-disk snapshots. Default 1.0 keeps the v0.2 upper-bound estimate. Set to 0.3 for typical real-world incremental dedup, or 0.0 to exclude snapshots from the total.

Example: compare_workload input shape

{
  "compute": [
    { "name": "web", "tier": "Web", "vcpus": 4, "memory_gb": 16, "quantity": 8,  "os_disk_gb": 100, "os_disk_type": "ssd" },
    { "name": "app", "tier": "App", "vcpus": 8, "memory_gb": 32, "quantity": 12, "os_disk_gb": 200, "os_disk_type": "ssd" },
    { "name": "db",  "tier": "DB",  "vcpus": 16, "memory_gb": 64, "quantity": 4, "os_disk_gb": 500, "os_disk_type": "ssd" }
  ],
  "storage": [
    { "name": "shared-fast", "tier": "DB",  "capacity_gb": 5000,  "disk_type": "ssd" },
    { "name": "shared-bulk", "tier": "App", "capacity_gb": 50000, "disk_type": "hdd" }
  ]
}

Snapshots (v0.2.1)

snapshot_count on storage rows and os_disk_snapshot_count on compute rows are now priced. Snapshot rates per cloud per disk type are bundled (~$0.05/GB-mo for AWS/Azure, ~$0.026/GB-mo for GCP).

Caveat — upper-bound estimate: snapshots are priced as snapshot_per_gb_month × full_capacity × quantity × snapshot_count. Real-world snapshots are incremental (only changed blocks), so actual cost is typically 20-50% of this model's number. If snapshots dominate your total, ask the cloud's calculator for a tighter estimate.

iops and throughput_mbs on storage rows are still accepted as metadata only — not used for SKU matching in this release.

Reserved Instance / Savings Plan estimator (v0.2.1)

compare_workload accepts an optional commitment parameter:

Value	Compute discount	Use case
none (default)	0%	On-demand only
1yr_no_upfront	30%	1-year AWS Savings Plan / Azure RI / GCP CUD (no upfront)
3yr_partial_upfront	50%	3-year, partial upfront — typical "we know our baseline" deals

Storage and snapshots are not discounted (most clouds don't offer meaningful storage commitments). Discount tiers are conservative averages — your actual rate depends on instance family, payment option, and region.

Pricing data

Prices are bundled as a curated dataset of common SKUs across 4 clouds:

• Compute (~50 VM SKUs across AWS / Azure / GCP / OCI, including OCI A1 Always Free + A2 Arm Ampere + E5 Flex)
• Block storage (SSD + HDD per cloud)
• Object storage (Hot / Cool / Archive tiers per cloud, including OCI Always Free 20 GB)
• Managed PostgreSQL (RDS / Azure DB / Cloud SQL / OCI Database with PostgreSQL)

OCI pricing is verified against Oracle's public pricing API. Each response includes an as_of date so you know how fresh the data is.

What's NOT modeled (real-world TCO killers)

• ✅ Egress / data transfer — modeled in v0.5 (compare_egress)
• ✅ Multi-AZ / HA replicas — modeled in v0.5 (multi_az: true on compare_workload)
• ✅ Snapshots upper-bound only — fixed in v0.5 (snapshot_incremental_factor)
• Reserved/Savings Plan SKU detail (we apply a flat tier discount, not per-region/per-family detail) — roadmap
• Multi-region pricing (currently us-east only; us-west / eu-west planned for v0.5.1) — roadmap
• IOPS-based storage matching (capacity-only) — roadmap
• Backup storage charges (some clouds free, others billed) — roadmap
• Request costs (PUT/GET pricing for object storage) — roadmap
• Retrieval costs for archive tiers (Glacier-style retrieval can be 10× the storage cost) — roadmap
• VPC peering / interconnect costs — roadmap

These are tracked roadmap items. Use cloudprice-mcp for the on-demand list-price baseline; do final TCO analysis with each cloud's own calculator before relying on numbers for big decisions.

Live API mode is on the roadmap (issue #1) — would fetch prices directly from each cloud's public pricing API:

• AWS: Price List Bulk API
• Azure: Retail Prices API
• GCP: Cloud Billing Catalog API

Track issue #1 for live mode and issue #2 for cross-cloud service mapping (RDS↔SQL DB↔Cloud SQL, etc.).
