No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/search_sequence for the schema, then POST the same URL with its arguments for the data.

Search the OEIS (On-Line Encyclopedia of Integer Sequences), the authoritative database of integer sequences. Identify a sequence from its first terms by passing a comma-separated list of integers (e.g. “1,1,2,3,5,8” finds the Fibonacci numbers), look up a specific sequence by A-number (e.g. “A000045”), or search free-text keywords (e.g. “prime gaps”). Returns up to 10 matching sequences per page with their A-number, name, terms, keywords, author, and offset. Use the start argument to paginate (10 results at a time).

Parameters

Name	Type	Required	Description
`query`	string	yes	A comma-separated list of integers (e.g. “1,1,2,3,5,8”), an A-number (e.g. “A000045”), or free-text keywords (e.g. “prime gaps”).
`start`	number	no	Pagination offset; results come 10 at a time. Default 0.
