text | string | Yes | Text to URL decode |
Parameters from the server's own tool schema.
Why url_decode_2 is rated Low
URL decoding is a deterministic string transformation utility that retrieves/decodes information from an encoded input. It has no side effects, creates no data, executes no code, and modifies nothing irreversibly. It is a simple utility function consistent with the server's purpose of providing 500+ deterministic tools for AI agents. The operation is read-only with no blast radius if misused.
From the tool's definition Tool name 'url_decode_2' and description 'URL decode a string' indicate a decoding operation that transforms encoded input into plaintext without modifying external state or data.
Attacks that exploit this kind of access
The rule that runs url_decode_2 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 url_decode_2, this is the rule to start with:
url_decode_2 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 url_decode_2 call is checked against it from then on.

URL decode a string. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
url_decode_2 accepts 1 parameter: text. 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 url_decode_2: 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.
url_decode_2 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 url_decode_2 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 url_decode_2. 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.
url_decode_2 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.
