Read Latest SAP Session Entries

sap_session_read_latest

Read latest entries from a high-level SDK session ID. SAP MCP context: Memory/session flow. Store only intentionally encrypted payloads or public hashes; session and vault PDAs are visible on-chain metadata.

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.

C2.4/5.0

Behavior1/5

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

Description contradicts annotation: tool is read-only but readOnlyHint is false. Does not disclose behavioral traits beyond generic memory/storage advice.

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?

Description is verbose with repetitive SAP MCP execution guidance that appears in both description and schema description. Core purpose is in first two sentences, rest is extraneous.

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?

Missing usage context relative to siblings, contradictory behavior flag, and no explanation of when to prefer this over other session read tools. Output schema exists but doesn't compensate for these gaps.

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?

Schema coverage is 100%, description adds no new meaning beyond 'high-level SDK session ID'. Baseline 3 applies.

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

Purpose4/5

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

Title and first sentence clearly state tool reads latest entries from a session ID. Distinguishes from sibling tools like sap_fetch_session which fetch session data generally, but noise from execution guidance reduces clarity.

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

Usage Guidelines2/5

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

No explicit guidance on when to use this tool vs alternatives like sap_session_status or sap_fetch_session. Execution guidance focuses on payment routing, not tool selection context.

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