Get block details by slot number
AI agents call get_block 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 block information from the Solana blockchain by slot number. It performs no write, execute, or destructive operations—it simply queries and returns data. The read-only nature and lack of side effects classify it as a Read operation with low severity, as misuse would only result in information disclosure or excessive API calls, not financial loss or data damage.

Get block details by slot number. 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_block: 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_block 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_block 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_block. 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_block 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.
