WHAT IT DOES

What hash_adler32 does on TinyFn

AI agents call hash_adler32 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 calculate Adler-32

Parameters from the server's own tool schema.

RISK

Why hash_adler32 is rated Low

This tool computes a checksum value from input data. It is a deterministic, read-only operation that retrieves or derives information without modifying, deleting, or executing external operations. Checksum calculation is a standard cryptographic/data integrity utility with no capability to alter state or trigger unintended consequences.

From the tool's definition Tool name 'hash_adler32' and description 'Calculate Adler-32 checksum' indicates a pure computational hashing function with no side effects.

RECOMMENDED RULE

The rule that runs hash_adler32 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 hash_adler32, this is the rule to start with:

hash_adler32 Allowed

hash_adler32 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": {
    "hash_adler32": {}
  }
}

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 hash_adler32 call is checked against it from then on.

FAQ

Questions about hash_adler32

What does the hash_adler32 tool do? +

Calculate Adler-32 checksum. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.

What parameters does hash_adler32 accept? +

hash_adler32 accepts 1 parameter: text. Required: text. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on hash_adler32? +

Register the TinyFn MCP server in PolicyLayer and add a rule for hash_adler32: 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 hash_adler32? +

hash_adler32 is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit hash_adler32? +

Yes. Add a rate_limit block to the hash_adler32 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 hash_adler32 completely? +

Set action: deny in the PolicyLayer policy for hash_adler32. 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 hash_adler32? +

hash_adler32 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.
