What analogous_colors does on TinyFn
AI agents call analogous_colors 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 |
|---|---|---|---|
hex_color | string | Yes | Hex color to get analogous colors for |
Parameters from the server's own tool schema.
Why analogous_colors is rated Low
This is a pure data retrieval function that computes and returns analogous colors from a color wheel. It has no side effects, does not create or modify persistent data, does not execute code or commands, and poses no risk of data loss or financial impact. It falls squarely within the Read category with low severity because misuse would at worst return unwanted color suggestions with no negative consequences.
From the tool's definition The tool 'Get analogous colors (adjacent colors on color wheel)' retrieves color information based on color theory—it queries and returns data without modifying, deleting, or executing external operations.
Attacks that exploit this kind of access
The rule that runs analogous_colors 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 analogous_colors, this is the rule to start with:
analogous_colors is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect TinyFn, apply this rule, and every analogous_colors call is checked against it from then on.
Questions about analogous_colors
Get analogous colors (adjacent colors on color wheel). It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
analogous_colors accepts 1 parameter: hex_color. Required: hex_color. 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 analogous_colors: 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.
analogous_colors 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 analogous_colors 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 analogous_colors. 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.
analogous_colors 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.
