AI agents call generate_hash to retrieve information from TinyFn without modifying anything — 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.
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
Attacks that exploit this kind of access
Generate hash of text. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
generate_hash accepts 2 parameters: text, algorithm. Required: text. The full parameter table on this page comes from the server's own tool schema.
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.
generate_hash 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 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.
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.
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.
generate_hash is one line of TinyFn's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
