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, or ChatGpt. Behind the scenes, your AI assistant calls Sumble's API on your behalf.

Sumble MCP is currently invite-only. Contact your Sumble account manager if you'd like access.

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 query tool are priced at 1 credit per 100 bytes of response data.

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.
