Read static metadata about the EIP-7702 support surface.
AI agents call eip7702_protocol_info to retrieve information from Tenzro Ledger MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves static metadata about EIP-7702 protocol support. It performs a read-only query operation that returns informational data about protocol capabilities without modifying, executing, or affecting any resources. No reversible or irreversible changes occur, and no external operations are triggered. This is a pure information lookup with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name includes 'protocol_info' and description states 'Read static metadata about the EIP-7702 support surface.' The verb 'Read' explicitly indicates data retrieval with no side effects.
Attacks that exploit this kind of access
Read static metadata about the EIP-7702 support surface. It is categorised as a Read tool in the Tenzro Ledger MCP MCP Server, which means it retrieves data without modifying state.
Register the Tenzro Ledger MCP server in PolicyLayer and add a rule for eip7702_protocol_info: 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 Tenzro Ledger MCP. Nothing to install.
eip7702_protocol_info 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 eip7702_protocol_info 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 eip7702_protocol_info. 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.
eip7702_protocol_info is provided by the Tenzro Ledger MCP server (https://canton-mcp.tenzro.network/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
