Get SAP Global State

sap_get_global_state

Read-onlyIdempotent

Free compact global SAP registry state read. Use for initial orientation before paid network analytics. 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: read/discovery 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.

A3.7/5.0

Behavior2/5

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

The description claims 'free' but later contradicts with 'priced by hosted x402 challenge', creating internal inconsistency. Annotations already declare readOnlyHint and idempotentHint, so the description adds mixed signals.

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 starts with a strong concise first sentence but then includes repetitive execution guidance that clutters the message. It could be more streamlined while retaining essential context.

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

Completeness3/5

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

With zero parameters and an output schema, the description covers purpose and usage context. However, the internal pricing contradiction (free vs. priced) leaves ambiguity about cost, reducing completeness.

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

Parameters4/5

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

The tool has no parameters and the input schema is empty with 100% description coverage. The description succinctly identifies the single resource returned (global state), so no parameter explanation is needed.

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 it is a 'free compact global SAP registry state read' and specifies its use for 'initial orientation before paid network analytics', distinguishing it from other SAP read tools.

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 for when to use ('initial orientation before paid network analytics', 'inspect current chain state before mutating...') and includes execution guidance on pricing and routing, but does not explicitly exclude alternatives among sibling read tools.

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