curl -X POST https://mate.tools/api/v1/hash.php \
-H "Content-Type: application/json" \
-d '{"text":"hello world","algorithms":["sha256","md5"]}'import urllib.request, json
req = urllib.request.Request(
"https://mate.tools/api/v1/hash.php",
data=json.dumps({"text":"hello world","algorithms":["sha256","md5"]}).encode(),
headers={"Content-Type": "application/json"},
)
with urllib.request.urlopen(req) as r:
print(json.load(r))const r = await fetch("https://mate.tools/api/v1/hash.php", {
method: "POST",
headers: { "Content-Type": "application/json" },
body: JSON.stringify({"text":"hello world","algorithms":["sha256","md5"]}),
});
console.log(await r.json()); Add to claude_desktop_config.json (Claude Desktop), ~/.cursor/mcp.json (Cursor), or any other MCP-compatible client:

Frequently Asked Questions
A hash function is a mathematical algorithm that transforms input data into a fixed-size string of characters. The output (hash) is unique to the input and cannot be reversed to obtain the original data.
For modern applications, SHA-256 or higher is recommended. MD5 and SHA1 are considered cryptographically broken and should only be used for non-security purposes like checksums.
While these hash functions can be used as part of a password system, modern password hashing should use specialized algorithms like bcrypt, Argon2, or PBKDF2 with proper salting.
