MCP server exposing cypari2 (PARI/GP) number theory library

mcp-parigp

MCP server exposing cypari2 (PARI/GP) number theory library

mcp-name: io.github.daedalus/mcp-parigp

Install

pip install mcp-parigp

Usage

As MCP Server

Run directly:

mcp-parigp

Or use with an MCP client by configuring in your settings:

{
  "mcpServers": {
    "mcp-parigp": {
      "command": "mcp-parigp"
    }
  }
}

In Python

from mcp_parigp import eval_expression, factor, isprime

# Evaluate PARI/GP expressions
result = eval_expression("factor(100)")
print(result)  # [[2, 2], [5, 2]]

# Factor integers
print(factor(100))  # [[2, 2], [5, 2]]

# Test primality
print(isprime(29))  # True
