AI agents call identify_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 |
|---|---|---|---|
hash_string | string | Yes | Hash string to identify |
Parameters from the server's own tool schema.
This tool retrieves or analyzes information about hash formats without side effects. It takes a hash as input and returns analysis results, fitting the Read category. The severity is low because even if misused, identifying a hash algorithm poses minimal security risk—it is informational only and does not enable unauthorized access or actions.
From the tool's definition Tool name 'identify_hash' and description 'Identify the possible algorithm of a hash based on its format' indicate a query/analysis operation that examines hash strings and returns information about their likely algorithms.
Attacks that exploit this kind of access
Identify the possible algorithm of a hash based on its format. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
identify_hash accepts 1 parameter: hash_string. Required: hash_string. 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 identify_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.
identify_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 identify_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 identify_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.
identify_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.
identify_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.
