WHAT IT DOES

What generate_hash does on TinyFn

AI agents call generate_hash to retrieve information from TinyFn 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	Text to hash
`algorithm`	string	—	Algorithm: md5, sha1, sha256, sha512

Parameters from the server's own tool schema.

RISK

Why generate_hash is rated Low

Hashing is a pure, deterministic computation that reads input text and produces a hash output. It does not modify, store, delete, or transmit any data. Consistent with the server's stated purpose of deterministic tools. Severity is low as misuse potential is minimal.

From the tool's definition Generate hash of text — deterministic transformation, no side effects, no external operations

RECOMMENDED RULE

The rule that runs generate_hash safely

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

generate_hash Allowed

generate_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": {
    "generate_hash": {}
  }
}

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

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

FAQ

Questions about generate_hash

What does the generate_hash tool do? +

Generate hash of text. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.

What parameters does generate_hash accept? +

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

How do I enforce a policy on generate_hash? +

Register the TinyFn MCP server in PolicyLayer and add a rule for generate_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 TinyFn. Nothing to install.

What risk level is generate_hash? +

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

Can I rate-limit generate_hash? +

Yes. Add a rate_limit block to the generate_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 generate_hash completely? +

Set action: deny in the PolicyLayer policy for generate_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 generate_hash? +

generate_hash is provided by the TinyFn MCP server (https://api.tinyfn.io/mcp/all/). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
