MCP support
Exposes four FX audit tools to MCP clients: fee calculation, provider comparison, invoice scoring, and mid-market rate lookup. Live provider comparisons require an API key; mid-market rates do not.

Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
