Python API

from mcp_ecdsa import generate_key, sign_data, verify_signature

# Generate key pair
result = await generate_key({"curve": "NIST256p"})
data = json.loads(result[0].text)

# Sign data
sign_result = await sign_data({
    "private_key": data["private_key"],
    "data": "Hello, World!"
})

# Verify signature
verify_result = await verify_signature({
    "public_key": data["public_key"],
    "signature": json.loads(sign_result[0].text)["signature"],
    "data": "Hello, World!"
})
