WHAT IT DOES

What util_hash does on Delx MCP Server

AI agents call util_hash to retrieve information from Delx MCP Server 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	Yes	String to hash
`algorithm`	string	—	Hash algorithm

Parameters from the server's own tool schema.

RISK

Why util_hash is rated Low

Hashing is a read-like operation: it takes input, applies a deterministic mathematical function, and returns output without altering state, creating obligations, or executing external operations. The tool has no capability to retrieve sensitive data, modify records, trigger actions, or affect system state.

From the tool's definition Tool description states 'Hash a string with SHA-256, SHA-1, or MD5' — cryptographic hashing is a deterministic transformation that produces no side effects and does not retrieve, modify, delete, execute, or transfer data.

RECOMMENDED RULE

The rule that runs util_hash safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Delx MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For util_hash, this is the rule to start with:

util_hash Allowed

util_hash is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "util_hash": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Delx MCP Server, apply this rule, and every util_hash call is checked against it from then on.

FAQ

Questions about util_hash

What does the util_hash tool do? +

Hash a string with SHA-256, SHA-1, or MD5. It is categorised as a Read tool in the Delx MCP Server MCP Server, which means it retrieves data without modifying state.

What parameters does util_hash accept? +

util_hash accepts 2 parameters: input, algorithm. Required: input. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on util_hash? +

Register the Delx MCP Server MCP server in PolicyLayer and add a rule for util_hash: 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 Delx MCP Server. Nothing to install.

What risk level is util_hash? +

util_hash is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit util_hash? +

Yes. Add a rate_limit block to the util_hash 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.

How do I block util_hash completely? +

Set action: deny in the PolicyLayer policy for util_hash. 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.

What MCP server provides util_hash? +

util_hash is provided by the Delx MCP Server MCP server (delx-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
