Cost-optimized MCP server: routes every tool call to the cheapest provider that returns a result.
Cost-optimized MCP server: routes every tool call to the cheapest provider that returns a result.
Frugal is an MCP server that sits between your agent and its tool providers. You describe the job — a search, an extraction, a render, or just an intent — and Frugal decides how to complete it, routing each call per policy: cheapest capable provider by default, fastest or premium when you say so, pinned or denied when compliance says so, with automatic failover when a provider errors or comes up empty. Every response carries the decision — provider_used, cost_usd, and (via frugal__execute) a one-line reason — so you can audit why each call went where it did.
Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
