Read and return the raw data of a Solana account (base64 encoded)
AI agents call read_account_data 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 account data from the Solana blockchain without side effects. It performs a query operation to fetch existing information. While the Solana MCP server overall includes financial and execute capabilities (as noted in sibling tools like execute_swap, burn_tokens), this specific tool is constrained to read-only operations.
From the tool's definition Tool name and description explicitly state 'Read and return the raw data' with no modification, deletion, or execution capability. Returns base64-encoded account data only.
Attacks that exploit this kind of access
Read and return the raw data of a Solana account (base64 encoded). 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 read_account_data: 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.
read_account_data 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 read_account_data 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 read_account_data. 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.
read_account_data 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.
read_account_data is one line of Solana MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
