Jupiter Create D C A

jupiter_createDCA

Create a Dollar-Cost Averaging (DCA) recurring order. Returns an unsigned transaction. SAP MCP context: Jupiter protocol tools are served as AgentKit ecosystem tools. Use them for quote, route, and swap preparation, then use SAP transaction preview/sign/submit tools when an unsigned transaction must pass MCP signer policy.

SAP MCP execution guidance: Intent: SAP MCP tool workflow. Pricing: paid value-action; preview cost and transaction effects before user confirmation. 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.

A4/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations indicate a write operation (readOnlyHint=false). The description adds significant behavioral context: it returns an unsigned transaction, is a paid value-action requiring user confirmation, and cannot be used as a hosted write. This goes beyond what annotations provide.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is lengthy with SAP-specific context that could be more concise. It includes redundant sections (SAP MCP context vs execution guidance). While front-loaded with the main purpose, the overall structure is somewhat verbose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given that an output schema exists, the description adequately covers the tool's purpose, return type (unsigned transaction), and its role in the SAP workflow (pricing, routing, signer boundary). It is complete for the intended use case.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Input schema has 100% description coverage, so the schema already documents all parameters. The description adds a note to use exact field names and avoid private key material, but does not provide additional semantic meaning beyond the schema. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'Create a Dollar-Cost Averaging (DCA) recurring order. Returns an unsigned transaction.' This is a specific verb+resource combination, and it distinguishes itself from sibling tools like jupiter_cancelDCA and jupiter_executeDCA.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides context on when to use this tool within the SAP MCP workflow, mentioning it returns an unsigned transaction and should be paired with preview/sign/submit tools. However, it lacks explicit guidance on when to choose DCA over other order types like limit orders or swaps.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
