Summary
Gives Claude the ability to generate cryptographic hashes on demand using common algorithms like MD5, SHA1, SHA256, SHA512, and bcrypt. The server runs as a hosted API at hash-generator.api.klymax402.com and uses SSE transport. You'd reach for this when you need to compute hashes during a conversation without writing throwaway code, whether for verifying file integrity, generating password hashes, or checking against known hash values. The x402 micropayment integration suggests usage based billing. The GitHub repo is pretty bare, so you're trusting the hosted endpoint. Straightforward utility for hash operations without the ceremony of spinning up your own tooling.

textstringThe text to hash
Hash Generator API
Cryptographic hash generator supporting MD5, SHA1, SHA256, SHA512, and bcrypt. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.
Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.
Quickstart -- MCP
Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):
{
"mcpServers": {
"hash-generator": {
"url": "https://hash-generator.api.klymax402.com/mcp"
}
}
}
Quickstart -- HTTP (x402)
curl -X POST "https://hash-generator.api.klymax402.com/api/hash" \
-H "Content-Type: application/json" \
-d '{"text":"..."}'
# -> 402 Payment Required, with an x402 payment challenge in the response body
Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.

crypto_generate_hash
Use this when you need to generate a cryptographic hash of text. Supports md5, sha1, sha256, sha512, and bcrypt algorithms. Returns the hash string, algorithm used, and hash length. Do NOT use for password strength checking — use security_check_password. Do NOT use for data validation — use data_validate_json.
Parameters
| Name | Type | Required | Description |
|---|---|---|---|
text | string | yes | The text to hash |
algorithm | string | no | Hash algorithm: md5, sha1, sha256, sha512, bcrypt (default: sha256) |
