Supper

Supper is an AI data agent for high-growth companies that connects a company's data, cleans it, and maps its business language so teams can answer critical questions in plain English within minutes. Supper reads from the customer's warehouse (Snowflake, BigQuery, Postgres, Redshift) and SaaS tools (CRM, ERP, marketing, product, payments) over a read-only connection, builds a verified semantic model, and exposes a hosted, OAuth-secured MCP server so any MCP-compatible AI assistant such as Claude can query that data via natural language and return dashboards and answers grounded in that model.

Supper is profiled on the APIs.io network. Tagged areas include Company, Data, Analytics, Artificial Intelligence, and MCP.

Supper’s developer surface includes documentation, API reference, pricing, signup flow, engineering blog, authentication, and 11 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/supper: open an issue to ask a question, or submit a pull request to add artifacts.
