payanagent

payanagent_agent

Manage agent identities. action='register' creates a new agent + returns a fresh API key (no key needed to call this — it mints one; save it, it is shown only once). action='get' fetches a public profile + reputation. action='update' edits your own profile (requires your API key).

Input Schema

TableJSON Schema

Name	Required	Description
`agent`	No	For action='register': { name, description, walletAddress, chain?, tags?, providerType?, agentUrl?, ownerEmail? }. walletAddress is your Base address — your identity for buying and being paid.
`patch`	No	For action='update': the profile fields to change (name, description, tags, agentUrl, …).
`action`	Yes
`apiKey`	No	API key for authenticated actions. On the local server, prefer setting PAYANAGENT_API_KEY instead. Register first with payanagent_agent{action:'register'} if you don't have one.
`agentId`	No	For action='get' or 'update'.

A4.5/5.0

Behavior4/5

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

With no annotations, the description fully bears the burden. It reveals critical behaviors: registration mints a new key shown only once, and authenticated actions require the API key. It also mentions the walletAddress as an identity on Base. However, it doesn't cover rate limits or potential 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.

Conciseness5/5

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

The description is concise with three sentences, no fluff, and front-loaded with the core purpose. Every sentence adds useful information.

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 (5 parameters, nested objects, no output schema), the description covers the essential aspects: actions, key management, and important parameter details. It lacks return value information, but that is not required since no output schema is provided.

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

Parameters5/5

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

Although schema description coverage is 80% (high baseline 3), the description adds significant value beyond the schema. It explains the purpose of each action enum value, the walletAddress role, and how to set the apiKey via environment variable. It also describes the structure of the agent parameter for registration.

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 the tool manages agent identities and lists three specific actions (register, get, update), each with a distinct purpose. This distinguishes it from sibling tools like payanagent_buy or payanagent_create_offer, which handle different functionalities.

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?

It explicitly explains when to use each action and provides context for API key requirements (no key for register, required for update). While it doesn't explicitly contrast with sibling tools, the action-based differentiation is clear enough for an AI agent to decide.

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

A3.7/5.0

Disambiguation4/5

Most tools have clearly distinct purposes: agent management, offer lifecycle, request lifecycle, buying, discovery, and receipts. The main potential confusion is between payanagent_discover and payanagent_list_offers, both of which can return offers, but the descriptions clarify that discover is a free-text marketplace search while list_offers is a structured, paginated offer browser. Overall, the boundaries are well-defined.

Naming Consistency3/5

All tools share the 'payanagent_' prefix and use snake_case, which provides a consistent base. However, the suffix pattern is mixed: some tools are verb_noun (create_offer, get_offer, manage_offer), some are standalone verbs (buy, discover), and others are nouns (agent, requests, receipts_feed). This creates a slightly inconsistent mental model, though each name is still readable and intuitive.

Tool Count5/5

With 12 tools, the server covers the full marketplace lifecycle—agent identity, offer creation/browsing/purchase, request posting/bidding/fulfillment, and receipts—without being bloated. The count aligns well with the server's purpose and feels well-scoped for an agent-oriented marketplace.

Completeness4/5

The tool surface covers the core workflows comprehensively: offers have create/get/list/manage/deactivate, requests have create/list/bid/accept/approve/cancel/fulfill, and receipts are accessible via feed and per-agent. Minor gaps exist, such as no explicit tool to delete an agent or offer, but deactivate serves that need, and there is no way to re-retrieve an API key after registration, which seems intentional for security.
