singularityagent__decode
Decode a hex calldata blob into a function signature and arguments. Recognizes common ERC-20/721/1155, WETH, Multicall3 and Safe calls out of the box, and unwraps batches — a multicall, an aggregate, an execTransaction or a multiSend reports the calls it carries under inner. Pass abi for anything...

What singularityagent__decode does on Rokha
AI agents use singularityagent__decode to create or update resources in Rokha, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Rokha environment.
| Parameter | Type | Required | Description |
|---|---|---|---|
abi | array | — | Human-readable ABI entries to decode against, e.g. ["function foo(uint256 bar)"]. |
data | string | Yes | Hex calldata, with or without the 0x prefix. |
lookup | boolean | — | When the selector is not recognized, ask a public 4-byte directory for candidate signatures. Off by default: it discloses the selector to a third party, and any |
Parameters from the server's own tool schema.
Why singularityagent__decode is rated Medium
An AI agent can call singularityagent__decode faster than any human can review: one bad instruction and it creates or modifies resources in Rokha by the hundred, each call as confident as the last.
Attacks that exploit this kind of access
The rule that runs singularityagent__decode safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Rokha, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For singularityagent__decode, this is the rule to start with:
singularityagent__decode stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Rokha, apply this rule, and every singularityagent__decode call is checked against it from then on.
Questions about singularityagent__decode
Decode a hex calldata blob into a function signature and arguments. Recognizes common ERC-20/721/1155, WETH, Multicall3 and Safe calls out of the box, and unwraps batches — a multicall, an aggregate, an execTransaction or a multiSend reports the calls it carries under inner. Pass abi for anything else, or set lookup to ask a public 4-byte directory for candidate signatures when the selector is unknown (those are third-party guesses, marked untrusted, and never promoted to signature). It is categorised as a Write tool in the Rokha MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
singularityagent__decode accepts 3 parameters: abi, data, lookup. Required: data. The full parameter table on this page comes from the server's own tool schema.
Register the Rokha MCP server in PolicyLayer and add a rule for singularityagent__decode: 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 Rokha. Nothing to install.
singularityagent__decode is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the singularityagent__decode 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 singularityagent__decode. 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.
singularityagent__decode is provided by the Rokha MCP server (https://rokha.ai/mcp/jsonrpc). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
