Get on-chain metadata for an NFT by its mint address
AI agents call get_nft_metadata to retrieve information from Solana MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves NFT metadata from the Solana blockchain by querying a mint address. It is a read-only operation with no side effects, no code execution, no data modification, and no financial impact. The blast radius of misuse is minimal—an agent could only retrieve publicly available metadata information that already exists on-chain.
From the tool's definition Tool name 'get_nft_metadata' and description 'Get on-chain metadata for an NFT by its mint address' indicate a query operation that retrieves blockchain data without modification or execution of transactions.
Attacks that exploit this kind of access
Get on-chain metadata for an NFT by its mint address. It is categorised as a Read tool in the Solana MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Solana MCP Server MCP server in PolicyLayer and add a rule for get_nft_metadata: 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 Server. Nothing to install.
get_nft_metadata 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_nft_metadata 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_nft_metadata. 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_nft_metadata is provided by the Solana MCP Server MCP server (visioneth/solana-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
