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!"
})Tools
