Python API
from mcp_oeis import mcp
# Get a sequence by ID
result = mcp.get_sequence_by_id("A000109")
print(result["terms"]) # [1, 1, 1, 2, 5, 14, ...]
# Search by terms
results = mcp.search_by_terms([1, 1, 2, 3, 5, 8])
print(results[0]["name"]) # "Fibonacci numbers"
# Search by name
results = mcp.search_by_name("prime")
print(results[0]["id"]) # "A000040"
MCP Tools
get_sequence_by_id
Get a sequence by its OEIS ID (e.g., "A000109" for simplicial polyhedra, "A000045" for Fibonacci).
search_by_terms
Search OEIS sequences by providing integer terms. For example, searching [1,1,2,3,5,8] will find the Fibonacci sequence.
search_by_name
Search OEIS sequences by name or keyword. For example, searching "Fibonacci" will find Fibonacci-related sequences.
