Used to look up merkle tree proof information for a compressed asset by public key (32 byte base58 encoded address)
AI agents call getAssetProof to retrieve information from Solana MCP Demo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs data retrieval only - it fetches proof information from the blockchain based on an asset's public key. There are no side effects, no data modification, no code execution, and no destructive or financial operations. The low severity reflects that unauthorized read access to merkle proofs poses minimal direct harm - the data is blockchain public information.
From the tool's definition Tool retrieves merkle tree proof information for a compressed asset by public key. The description indicates this is a lookup/query operation with no modification of state, matching the 'fetch' and 'get' patterns of the Read category.
Attacks that exploit this kind of access
Used to look up merkle tree proof information for a compressed asset by public key (32 byte base58 encoded address). It is categorised as a Read tool in the Solana MCP Demo MCP Server, which means it retrieves data without modifying state.
Register the Solana MCP Demo MCP server in PolicyLayer and add a rule for getAssetProof: 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 Solana MCP Demo. Nothing to install.
getAssetProof 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 getAssetProof 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 getAssetProof. 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.
getAssetProof is provided by the Solana MCP Demo MCP server (metaplex-foundation/das-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
