Get SAP Agent

sap_get_agent

Read-onlyIdempotent

Free exact SAP agent identity read by owner wallet. If omitted, fetches the connected wallet agent. Use this before paid 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: 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.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`wallet`	No	Solana public key of the agent owner wallet (base58). If omitted, uses the connected wallet.

Output Schema

TableJSON Schema

Name	Required	Description	Default
`content`	Yes	MCP content blocks returned to the caller.
`isError`	No	True when the tool result represents an application-level error.

A4.2/5.0

Behavior4/5

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

Annotations declare readOnlyHint, idempotentHint, not destructive. Description reinforces read-only nature and adds context about not receiving keypair bytes. No contradiction.

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 repeated guidance in the input schema. It could be more concise, though front-loaded with core purpose.

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 the complexity of SAP and presence of output schema, the description covers intent, pricing, routing, and signer boundary. It adequately informs an agent how and when to use the tool.

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?

Schema covers the parameter fully (100%). Description adds value by clarifying fallback behavior when wallet is omitted, which supplements 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 description states it reads SAP agent identity by owner wallet (or connected wallet) and positions it before paid discovery. It is specific and distinguishes from siblings like sap_discover_agents.

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 advises to use before paid discovery when the wallet is known, providing clear context. It also gives execution guidance (call sap_estimate_tool_cost first), but does not explicitly list alternative tools.

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