WHAT IT DOES

What jito_sendBundle does on Sap

AI agents use jito_sendBundle to create or update resources in Sap, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sap environment.

Parameter	Type	Required	Description
`tipLamports`	string	—	Raw token amount (smallest unit)
`transactions`	array	Yes	Array of base64-encoded signed transactions (max 5)

Parameters from the server's own tool schema.

RISK

Why jito_sendBundle is rated Medium

An AI agent can call jito_sendBundle faster than any human can review: one bad instruction and it creates or modifies resources in Sap by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs jito_sendBundle safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Sap, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For jito_sendBundle, this is the rule to start with:

jito_sendBundle Rate-limited

jito_sendBundle stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about jito_sendBundle

What does the jito_sendBundle tool do? +

Send a Jito bundle for MEV-protected, atomic transaction execution. SAP MCP context: This Synapse AgentKit tool is served beside the sap_* SDK tools. Use sap_agent_identity_plan, sap_payments_register_agent, sap_payments_update_agent, and sap_publish_tool_by_name when the capability should become part of an on-chain SAP agent profile or tool registry entry. SAP MCP execution guidance: Intent: SAP MCP tool workflow. Pricing: paid read-premium; estimate first, then use sap_payments_call_paid_tool when the runtime cannot replay x402 natively. Routing: hosted accountless write is blocked; do not call this as a paid hosted write and no x402 payment should be charged. Use the local sap_payments bridge or a hosted unsigned builder when user signing is required. Signer boundary: user-controlled local profile or external signer; OOBE hosted MCP remains non-custodial. It is categorised as a Write tool in the Sap MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does jito_sendBundle accept? +

jito_sendBundle accepts 2 parameters: tipLamports, transactions. Required: transactions. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on jito_sendBundle? +

Register the Sap MCP server in PolicyLayer and add a rule for jito_sendBundle: 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 Sap. Nothing to install.

What risk level is jito_sendBundle? +

jito_sendBundle is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit jito_sendBundle? +

Yes. Add a rate_limit block to the jito_sendBundle 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.

How do I block jito_sendBundle completely? +

Set action: deny in the PolicyLayer policy for jito_sendBundle. 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.

What MCP server provides jito_sendBundle? +

jito_sendBundle is provided by the Sap MCP server (https://mcp.sap.oobeprotocol.ai/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
