gcp-cost-mcp-server
Provides an MCP server with tools to estimate Google Cloud (GCP) running costs by querying Google Cloud Billing Catalog API for SKUs/pricing and (separately) fetching free-tier information from GCP documentation, then calculating estimated monthly costs with automatic free-tier deduction.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Security posture is inferred from documentation: uses Google Cloud credentials (ADC/service account) and avoids hardcoded keys. TLS is assumed for Google APIs. The README does not discuss least-privilege scopes, secure logging practices, token handling, or dependency/SBOM/CVE status; free-tier/doc scraping introduces external network interaction that should be monitored.
⚡ Reliability
Best When
You want AI-assisted, interactive cost estimation for common GCP services using public catalog/pricing data and free-tier guidance, and you can provide required usage inputs (region, SKU identifiers/parameters, hours/quantity).
Avoid When
You need exact, invoice-matching results, internal/private pricing, or strong guarantees about free-tier accuracy; also avoid when you cannot supply the necessary usage dimensions.
Use Cases
- • Estimate monthly costs for a single GCP service (e.g., Cloud Run, Cloud SQL)
- • Break down costs by SKU and pricing tiers for a given service/region
- • Generate step-by-step estimation requirements (“estimation guide”) for an arbitrary GCP service
- • Compare pricing inputs by exploring available services/SKUs/prices
- • Assist in architecture-level cost estimation by calling tools for multiple services
Not For
- • Authoritative billing statements or exact invoice totals (it is an estimator)
- • Workloads that require commitment/discount modeling beyond what the tool documents
- • Use as a general-purpose billing API proxy for arbitrary billing queries
- • Compliance-critical cost accounting without validation
Interface
Authentication
README describes using OAuth authentication implicitly via ADC/service account credentials for accessing public pricing/catalog data; it does not specify OAuth flows or explicit scopes.
Pricing
The MCP server itself is a tool; costs would depend on Google Cloud APIs usage (typically low/public catalog access) but no workload cost model is documented here.
Agent Metadata
Known Gotchas
- ⚠ Estimation outputs depend on SKU selection and free-tier deduction logic; inaccurate or missing user inputs (region, usage quantities, hours) can produce misleading estimates.
- ⚠ Dynamic guide generation and documentation scraping/search for free-tier info may be brittle if external sources change.
- ⚠ Authentication via ADC/service account must be correctly configured in the environment where the MCP server runs.
