MCP

With Sumble MCP, you can ask questions in natural language and get back structured data about organizations, technologies, job postings, and people - directly inside tools like Claude Desktop, Cursor, ChatGpt, or Gemini CLI. Behind the scenes, your AI assistant calls Sumble's API on your behalf.

Getting started

Sumble is now listed in the Claude and ChatGPT app directories, so you can install it with one click on those platforms.

See this video to see how to find it in Claude

Compatibility

On Claude and ChatGPT you can install Sumble directly from the app directory. Cursor, Claude Code, and Gemini CLI use a custom MCP connection. It is possible in these LLMs

Credits

MCP calls consume credits from your Sumble account, just like the REST API. The structured tools (find, enrich) follow the same pricing as the corresponding API endpoints. SQL queries via the RunSqlQuery tool are priced at 1 credit per 100 bytes of response data, so you pay only for the rows you get back. A query that matches more than 1,000 rows fails without returning rows or charging credits: add a LIMIT of 1,000 or less, aggregate in SQL, or narrow the WHERE clause.

An MCP request that would cost more than 500 credits is refused. Nothing is charged and no data is returned. To go ahead, your assistant passes allow_expensive_query, which it should do only after asking you. Assistants that cannot pass the parameter have to narrow the request instead. The REST API is not affected.

You can check your balance at any time by asking your assistant, or visit sumble.com/account. To purchase additional credits, go to Account > Purchase.

See Credits for details on monthly allocations and purchasing.
