Get Next Settlement Index

sap_next_settlement_index

Destructive

Read the next V2 settlement index. SAP MCP context: Payment and settlement flow. Estimate or fetch state before creating escrows or settling calls; write operations require an enabled signer mode and MCP policy approval.

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: paid hosted call; call sap_estimate_tool_cost first, then use sap_payments_call_paid_tool if the runtime cannot handle x402 natively. Signer boundary: hosted reads/builders never receive keypair bytes; value-moving results must be finalized locally when signing is required.

B3.1/5.0

Behavior1/5

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

The description says 'Read' but annotations have destructiveHint=true and readOnlyHint=false, creating a strong contradiction. The description also mixes guidance for other tools without clarifying this tool's side effects.

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

Conciseness2/5

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

The description is verbose, repeating execution guidance (pricing, routing, signer boundary) both in the description and the schema description. The core message is buried under redundant workflow instructions.

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

Completeness2/5

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

An output schema exists, but the tool's behavior is unclear due to the contradiction. The description does not clarify whether calling this tool is destructive or idempotent, which is critical for an agent to use it correctly.

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?

All 3 parameters are documented in the input schema with full coverage (100%). The description repeats execution guidance but does not add new parameter-level meaning beyond the schema.

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 first sentence 'Read the next V2 settlement index' clearly states the verb (Read) and resource (next V2 settlement index). It is specific and distinct from sibling tools that involve creating or settling escrows.

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: 'Estimate or fetch state before creating escrows or settling calls' and mentions write operation requirements. However, it does not explicitly exclude alternative tools or provide when-not-to-use guidance.

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