hash_text
Generate a cryptographic hash of input text. Use this for password hashing, data integrity checks, digital signatures, or any scenario requiring a one-way hash of a string. Parameters: text — The text to hash (required). algorithm — Hashing algorithm: "md5", "sha1", "sha256", or "sha512" (default...

What hash_text does on X402 Middleware
AI agents call hash_text to retrieve information from X402 Middleware 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 |
|---|---|---|---|
text | string | Yes | |
encoding | string | — | |
algorithm | string | — |
Parameters from the server's own tool schema.
Why hash_text is rated Low
Hash generation is a read-only cryptographic operation. It computes and returns a value based on input without creating, modifying, deleting, or executing anything in external systems. The tool has no capability to alter state, run code, or interact with financial systems. It is a pure function for cryptographic purposes.
From the tool's definition Tool description states it generates 'a cryptographic hash of input text' and is used for 'password hashing, data integrity checks, digital signatures, or any scenario requiring a one-way hash of a string.' The operation is purely computational—taking input…
Attacks that exploit this kind of access
The rule that runs hash_text safely
PolicyLayer is an MCP gateway: it sits between your AI agents and X402 Middleware, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For hash_text, this is the rule to start with:
hash_text 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 X402 Middleware, apply this rule, and every hash_text call is checked against it from then on.
Questions about hash_text
Generate a cryptographic hash of input text. Use this for password hashing, data integrity checks, digital signatures, or any scenario requiring a one-way hash of a string. Parameters: text — The text to hash (required). algorithm — Hashing algorithm: "md5", "sha1", "sha256", or "sha512" (default: "sha256"). SHA-256 and SHA-512 are recommended for security-sensitive use. encoding — Output encoding: "hex" or "base64" (default: "hex"). It is categorised as a Read tool in the X402 Middleware MCP Server, which means it retrieves data without modifying state.
hash_text accepts 3 parameters: text, encoding, algorithm. Required: text. The full parameter table on this page comes from the server's own tool schema.
Register the X402 Middleware MCP server in PolicyLayer and add a rule for hash_text: 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 X402 Middleware. Nothing to install.
hash_text 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_text 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_text. 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_text is provided by the X402 Middleware MCP server (@gadgethumans/x402). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
