Used to look up transaction by signature (64 byte base58 encoded string)
AI agents call getTransaction to retrieve information from Solana Model Context Protocol (MCP) Demo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves transaction information from the Solana blockchain by signature lookup. It performs a read-only query operation with no side effects, no data modification, no code execution, and no financial impact. The low severity reflects minimal blast radius - an AI agent misusing this would only retrieve existing public blockchain data.
From the tool's definition Tool description explicitly states it is 'Used to look up transaction by signature' - a pure query operation that retrieves transaction data without modification or execution.
Documented attack patterns abuse exactly the kind of access getTransaction gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Solana Model Context Protocol (MCP) Demo, and nothing reaches the server without passing your rules. This is the rule we recommend for getTransaction:
{
"version": "1",
"default": "deny",
"tools": {
"getTransaction": {}
}
}getTransaction is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Used to look up transaction by signature (64 byte base58 encoded string). It is categorised as a Read tool in the Solana Model Context Protocol (MCP) Demo MCP Server, which means it retrieves data without modifying state.
Register the Solana Model Context Protocol (MCP) Demo MCP server in PolicyLayer and add a rule for getTransaction: 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 Model Context Protocol (MCP) Demo. Nothing to install.
getTransaction 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 getTransaction 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 getTransaction. 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.
getTransaction is provided by the Solana Model Context Protocol (MCP) Demo MCP server (solana-foundation/solana-dev-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
