Perform a JSON-RPC call against the Sei EVM endpoint. Provide rpc_method and optional params; specify chain_id or an explicit endpoint override.
AI agents invoke RpcLcdController-callEvmRpc to trigger actions in Seitrace Insights MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool executes arbitrary JSON-RPC methods against an EVM endpoint. Depending on the rpc_method provided, it could trigger state-changing transactions, contract interactions, or other operations whose effects depend entirely on the arguments passed. This goes beyond simple reads — it can execute arbitrary RPC calls including write/execute operations on the blockchain.

Documented attack patterns abuse exactly the kind of access RpcLcdController-callEvmRpc gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Seitrace Insights MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for RpcLcdController-callEvmRpc:
{
"version": "1",
"default": "deny",
"tools": {
"RpcLcdController-callEvmRpc": {
"limits": [
{
"counter": "rpclcdcontroller-callevmrpc_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}RpcLcdController-callEvmRpc stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Perform a JSON-RPC call against the Sei EVM endpoint. Provide rpc_method and optional params; specify chain_id or an explicit endpoint override. It is categorised as a Execute tool in the Seitrace Insights MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Seitrace Insights MCP Server MCP server in PolicyLayer and add a rule for RpcLcdController-callEvmRpc: 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 Seitrace Insights MCP Server. Nothing to install.
RpcLcdController-callEvmRpc is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the RpcLcdController-callEvmRpc 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 RpcLcdController-callEvmRpc. 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.
RpcLcdController-callEvmRpc is provided by the Seitrace Insights MCP Server MCP server (seitrace/seitrace-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Seitrace Insights MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
