Rhumb MCP server

Rhumb is a helper that lets your AI look up and compare online services, then run certain tasks for you. It scores services on how well they work with AI, so you can pick a good one without guessing. It is handy if you often ask your AI to send email, pull data, or generate content and want to know what it will cost first.

What this MCP server does

You ask your AI to do something, like send an email or extract text from a page. Your AI uses this helper to search Rhumb's list of scored services and pick a good match. The helper checks the cost and health of that service, then runs the task if you have a key. You get back the result plus a receipt that shows what ran and what it cost.

What it gives back to you

You get back lists of services with scores, short summaries of failure patterns, and cost estimates in plain numbers. When you run a task, you get the result plus a receipt that shows which service ran, how long it took, and what it cost. Your chat shows these as text answers, tables, or links you can click.
