Check SAP Agent Active

sap_is_agent_active

Micro-read exact activity check for an owner wallet. Use this before read-premium discovery when the wallet is known. SAP MCP context: Read-only SAP SDK wrapper against the configured Solana RPC and SAP program. Use these reads to inspect current chain state before mutating registry, payment, reputation, memory, or tool accounts.

SAP MCP execution guidance: Intent: SAP MCP tool workflow. Pricing: priced by hosted x402 challenge. 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.

TDQS

B3.1/5.0

Behavior1/5

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

The description describes the tool as a 'micro-read' (a read operation), but annotations set readOnlyHint=false, contradicting the description. This inconsistency undermines transparency. Additionally, the tool is marked as openWorldHint=true but no explanation is given.

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 includes extensive boilerplate about SAP MCP context, pricing, routing, and signer boundary that is not specific to this tool. This adds unnecessary length and reduces conciseness, though the purpose is front-loaded.

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?

Given the simple nature of the tool (1 param, output schema present), the description covers purpose and usage but lacks details about output, error behavior, or edge cases. The contradiction with annotations further reduces completeness.

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?

There is one parameter ('wallet') with a schema description that is already clear. The description adds no additional semantic meaning beyond the schema, and schema coverage is 100%, so the baseline score of 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 first sentence clearly states the tool does a 'micro-read exact activity check for an owner wallet' and specifies its use case. The name and title also align, making the purpose unambiguous.

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 explicitly instructs to use this tool 'before read-premium discovery when the wallet is known', providing clear context. It does not explicitly exclude alternatives, but the guidance is helpful.

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