AI agents call add as a supporting operation in Ethereum Tools workflows.
The description is empty and the name 'add' is too ambiguous to classify confidently. In the context of an Ethereum toolkit, it could mean adding a wallet to track, adding a token to a list, or something else entirely. Without any description, cannot assign a meaningful category. Defaulting to Other with very low confidence.
From the tool's definition Tool name is 'add' with empty description. No information about what this tool does.
Documented attack patterns abuse exactly the kind of access add gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ethereum Tools, and nothing reaches the server without passing your rules. This is the rule we recommend for add:
{
"version": "1",
"default": "deny",
"tools": {
"add": {
"limits": [
{
"counter": "add_rate",
"window": "minute",
"max": 60,
"scope": "grant"
}
]
}
}
}add gets a rate cap, and everything else on the server is denied unless you say otherwise.

add. It is categorised as a Other tool in the Ethereum Tools MCP Server, which means it performs auxiliary operations.
Register the Ethereum Tools MCP server in PolicyLayer and add a rule for add: 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 Ethereum Tools. Nothing to install.
add is a Other tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the add 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 add. 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.
add is provided by the Ethereum Tools MCP server (0xgval/evm-mcp-tools). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Ethereum Tools, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
