WHAT IT DOES

What validate_semver does on TinyFn

AI agents call validate_semver 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
`version`	string	Yes	Semantic version to validate

Parameters from the server's own tool schema.

RISK

Why validate_semver is rated Low

This tool performs input validation—a read-only operation that analyzes a semantic version string and reports whether it conforms to the semver specification. It has no side effects, creates no data modifications, executes no code, and cannot cause damage.

From the tool's definition Tool name 'validate_semver' and description 'Validate a semantic version string' indicate a query/validation operation that checks input against a pattern and returns true/false or validation result without modifying data or executing external operations.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

validate_semver Allowed

validate_semver 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": {
    "validate_semver": {}
  }
}

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 validate_semver call is checked against it from then on.
