Frequently asked questions

What is an MCP server?

MCP (Model Context Protocol) is an open protocol that lets AI agents connect to external data sources and tools such as web search, databases, browsers, code sandboxes, and SaaS APIs through a standardized interface.

What does this calculator include?

It estimates per-call and monthly MCP server cost, retry and failure overhead, self-hosting infrastructure, human review labor, setup, and maintenance. It does not include base LLM token cost.

How are retries costed?

Failed MCP calls still cost the base call. A configurable share of failures are retried, and retries can use a more expensive fallback provider or longer execution, captured by the retry cost multiplier.

When should I self-host MCP servers?

Self-hosting lowers per-call SaaS fees but adds compute, storage, and maintenance cost. The calculator lets you blend hosted and self-hosted MCP usage to find the cheapest route for your volume.

Does latency affect cost?

Latency itself is not billed directly, but slow calls reduce throughput and can increase concurrency needs. The calculator reports total latency overhead so you can size workers or queue infrastructure.

How can I reduce MCP spend?

Cache search and DB results, batch MCP calls, choose cheaper providers for low-risk lookups, self-host stable integrations, and reduce retry loops with better timeouts and idempotent calls.

MCP (Model Context Protocol) server costs are based on typical per-call SaaS/API pricing and self-hosting infrastructure estimates. Replace defaults with your actual provider rates.
