Fetch and decode a Solana transaction to extract pump.fun events (launch, trade, graduation, claim).
AI agents call decode_pump_transaction to retrieve information from Agenti without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool fetches and decodes existing transaction data from the Solana blockchain to extract event information. It performs no mutations, deletions, financial transfers, or code execution. While the server as a whole handles financial operations (payments, spending), this particular tool is strictly a read-only query of historical transaction data.
From the tool's definition Tool description states 'Fetch and decode a Solana transaction to extract pump.fun events' — this is a retrieval operation that queries blockchain data without modifying state or executing actions.
Documented attack patterns abuse exactly the kind of access decode_pump_transaction gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Agenti, and nothing reaches the server without passing your rules. This is the rule we recommend for decode_pump_transaction:
{
"version": "1",
"default": "deny",
"tools": {
"decode_pump_transaction": {}
}
}decode_pump_transaction is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Fetch and decode a Solana transaction to extract pump.fun events (launch, trade, graduation, claim). It is categorised as a Read tool in the Agenti MCP Server, which means it retrieves data without modifying state.
Register the Agenti MCP server in PolicyLayer and add a rule for decode_pump_transaction: 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 Agenti. Nothing to install.
decode_pump_transaction 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 decode_pump_transaction 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 decode_pump_transaction. 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.
decode_pump_transaction is provided by the Agenti MCP server (nirholas/agenti). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
