The LODA API MCP Server enables comprehensive interaction with LODA programs and OEIS integer sequences through a full-featured API.

Explore integer sequences: Retrieve detailed information about specific OEIS sequences by their A-number identifiers or search using keywords and names
Discover LODA programs: Access individual LODA assembly language programs by ID or search using keywords with pagination support
Execute LODA programs: Run LODA code to compute sequence terms with configurable term count and offset
Submit new programs: Contribute LODA program implementations for specific sequences
Monitor project statistics: View summary statistics about the LODA project's scope, growth, and browse all contributors with their contribution counts

LODA MCP Server

A Model Context Protocol (MCP) server for the LODA Language API, providing seamless access to the LODA language and integer sequences from the On-Line Encyclopedia of Integer Sequences® (OEIS®).
