What singularityagent__read_contract does on Rokha
AI agents call singularityagent__read_contract to retrieve information from Rokha 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 |
|---|---|---|---|
abi | string | — | Human-readable ABI entry, e.g. "function balanceOf(address) view returns (uint256)". |
args | array | — | Arguments for the call, in order. |
chain | string | Yes | Chain id or alias. |
method | string | — | EVM function name, e.g. "balanceOf". |
address | string | Yes | Contract address (EVM) or account address (Solana). |
atBlock | string | number | — | Read state as of this block height instead of now. Supported on EVM (needs an archive endpoint) and Cosmos (needs an archive LCD). Solana and UTXO chains reject |

Attacks that exploit this kind of access
The rule that runs singularityagent__read_contract 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__read_contract, this is the rule to start with:
singularityagent__read_contract 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 Rokha, apply this rule, and every singularityagent__read_contract call is checked against it from then on.
Questions about singularityagent__read_contract
Call a view function on an EVM contract (supply abi in human-readable form plus method), or read parsed account data on Solana. Pass atBlock to call against a past block. Never sends a transaction. It is categorised as a Read tool in the Rokha MCP Server, which means it retrieves data without modifying state.
singularityagent__read_contract accepts 6 parameters: abi, args, chain, method, address, atBlock. Required: chain, address. 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__read_contract: 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__read_contract 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 singularityagent__read_contract 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__read_contract. 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__read_contract 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.
