About io.github.daedalus/mcp-ecdsa
io.github.daedalus/mcp-ecdsa is an MCP server published by daedalus in the Blockchain category: mCP server for ECDSA cryptography.
Six months or more without a commit doesn't mean the server is broken, but check the open issues before depending on it in production.
Install
uvx mcp-ecdsapip install mcp-ecdsaThis server has no ConduID identity, so agent calls to it are not receipted. Pin the version you install and review the source before granting it credentials.

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!"
})
