hash_encode
Hashing, HMAC and encoding toolkit: digests (MD5, SHA-1/2/3, Keccak-256 as used by Ethereum, RIPEMD-160, Whirlpool, CRC32/CRC32C, Adler-32, FNV-1a, xxHash32/64/3/128, MurmurHash3), HMAC (SHA-1/2/3, MD5) with hex or base64 output, encode/decode between UTF-8, hex, base64, base64url, base32, base58...

What hash_encode does on ScorpTech x402 API
AI agents call hash_encode to retrieve information from ScorpTech x402 API without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
input | string | — | Input string (max 100 KB), interpreted per input_encoding |
hashes | array | — | Digest algorithms, or "all" (default md5, sha1, sha256, sha512, sha3-256, keccak256, crc32b) |
generate | object | — | Optional generation instead of / besides input: {"uuid": "v4"|"v7", "count": 1-100} and/or {"random_bytes": 1-1024} |
hmac_key | string | — | Optional HMAC key (never echoed) |
identify | boolean | — | Guess what the input string is (default true) |
encodings | array | — | Output encodings (default hex, base64, base64url, base32, base58, url) |
input_encoding | string | — | utf8 (default), hex, base64, base64url, base32, base58 or url: decode the input to bytes first |
hmac_algorithms | array | — | HMAC algorithms (default sha256) |
hmac_key_encoding | string | — | utf8 (default), hex, base64, base64url |
Parameters from the server's own tool schema.
Why hash_encode is rated Low
Even though hash_encode only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs hash_encode safely
PolicyLayer is an MCP gateway: it sits between your AI agents and ScorpTech x402 API, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For hash_encode, this is the rule to start with:
hash_encode is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect ScorpTech x402 API, apply this rule, and every hash_encode call is checked against it from then on.

Offline. Price: $0.005 USDC per successful call (x402, Solana). Same tool over HTTPS: POST https://scorptech.it.com/api/x402/v1/hash-encode. It is categorised as a Read tool in the ScorpTech x402 API MCP Server, which means it retrieves data without modifying state.
hash_encode accepts 9 parameters: input, hashes, generate, hmac_key, identify, encodings, input_encoding, hmac_algorithms, hmac_key_encoding. The full parameter table on this page comes from the server's own tool schema.
Register the ScorpTech x402 API MCP server in PolicyLayer and add a rule for hash_encode: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches ScorpTech x402 API. Nothing to install.
hash_encode is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the hash_encode rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for hash_encode. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
hash_encode is provided by the ScorpTech x402 API MCP server (https://scorptech.it.com/api/x402/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
