What is the Infracost MCP Server?
Connect Infracost to your AI agent to bring financial visibility and governance to your Infrastructure as Code (IaC) workflows. Prevent cloud cost surprises before they happen.
What you can do
- Cost Guardrails — List, create, and manage guardrails that trigger alerts or block Pull Requests when cost increases exceed your defined thresholds.
- Tagging Governance — Enforce organizational standards by updating tagging policies, ensuring all cloud resources are correctly attributed to departments or projects.
- Custom Pricing — Manage enterprise-specific price books for AWS and Azure to ensure cost estimates reflect your actual negotiated discounts.
- Business Context — Upload custom properties from external systems like ServiceNow or Backstage to map cloud costs to your internal organizational hierarchy.
- Pricing Queries — Programmatically query cloud pricing data to compare costs across different resource types and regions.
How it works
- Subscribe to this server
- Enter your Infracost API Token
- Start managing your cloud governance from Claude, Cursor, or any MCP-compatible client
Who is this for?
- DevOps Engineers — automate the enforcement of cost policies and tagging standards directly within the CI/CD flow.
- FinOps Teams — gain real-time visibility into infrastructure spend and manage custom enterprise discounts without manual spreadsheets.
- Engineering Managers — set budget thresholds and receive automated summaries of cost impacts for proposed infrastructure changes.

Frequently asked questions
How can I see all active cost guardrails for my organization?
You can use the list_guardrails tool by providing your organization slug. The agent will return a list of all configured thresholds, including cost increase limits and whether they block PRs.
Can I enforce mandatory tags for my cloud resources using this server?
Yes! Use the update_tagging_policy tool to define mandatory tag keys and allowed values. This helps maintain standards across all your repositories.
Is it possible to block expensive Pull Requests automatically?
Absolutely. When using create_guardrail or update_guardrail, you can set the blockPr parameter to true. This ensures that any infrastructure change exceeding your budget cannot be merged without review.
How does the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
