Derives an address from a public key
AI agents call derive-address-from-pubkey to retrieve information from Osmosis MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a pure read operation that performs deterministic cryptographic computation. It takes a public key as input and returns the corresponding blockchain address. No data is created, modified, deleted, or executed on the blockchain. The operation has no side effects and poses minimal security risk even if misused—deriving an address from a public key is a standard, public cryptographic operation.
From the tool's definition Tool name 'derive-address-from-pubkey' and description 'Derives an address from a public key' indicate a cryptographic derivation operation that retrieves/computes a blockchain address from public key data without modifying any state.
Attacks that exploit this kind of access
Derives an address from a public key. It is categorised as a Read tool in the Osmosis MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Osmosis MCP Server MCP server in PolicyLayer and add a rule for derive-address-from-pubkey: 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 Osmosis MCP Server. Nothing to install.
derive-address-from-pubkey 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 derive-address-from-pubkey 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 derive-address-from-pubkey. 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.
derive-address-from-pubkey is provided by the Osmosis MCP Server MCP server (myronkoch-dev/mcp-osmosis). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
