Get the EVM address derived from a private key
AI agents call get_address_from_private_key to retrieve information from SEI MCP Server V2 without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a deterministic, read-only operation: deriving an EVM address from a private key. It retrieves computed data without modifying state, creating assets, executing code, destroying data, or moving funds. While the context involves blockchain operations, this specific tool is a pure data transformation function.
From the tool's definition Tool name is 'get_address_from_private_key' and description states 'Get the EVM address derived from a private key' — a straightforward cryptographic derivation with no side effects.
Attacks that exploit this kind of access
Get the EVM address derived from a private key. It is categorised as a Read tool in the SEI MCP Server V2 MCP Server, which means it retrieves data without modifying state.
Register the SEI MCP Server V2 MCP server in PolicyLayer and add a rule for get_address_from_private_key: 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 SEI MCP Server V2. Nothing to install.
get_address_from_private_key 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 get_address_from_private_key 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 get_address_from_private_key. 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.
get_address_from_private_key is provided by the SEI MCP Server V2 MCP server (testinguser1111111/sei-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
get_address_from_private_key is one line of SEI MCP Server V2's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
