List merchants you can act as

list_my_merchants
Read-onlyIdempotent

FALLBACK merchant list for clients WITHOUT UI support.

Do NOT use this to choose or switch merchants when a UI is available — call jobmojito_configuration instead (it renders an interactive picker), and do not hand-format a merchant list as text. Use this tool only when the client cannot render MCP App UI. Returns the user's own account plus any sub-merchants; after a pick, pass merchant_id=<chosen id> on subsequent calls (OMIT for the own account).

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
searchNoOptional case-insensitive filter on sub-merchant name.
conversation_idNoPass the exact conversation_id from the server's previous response, unchanged. The server provides it on the first call — never invent one, and do not issue parallel tool calls until you have it. Keep passing the same conversation_id for the rest of the conversation, including after later user messages or on a different task; do not reset it when the user starts a new request.

TDQS

A4.8/5.0
Behavior5/5

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

Annotations already cover safety (readOnly, idempotent, non-destructive, closed-world), yet the description adds genuinely new behavioral context: the fallback trigger condition, the downstream protocol (pick a merchant then pass merchant_id=<chosen id> on later calls, omitting it for the own account), and the anti-pattern to avoid. That multi-step flow context is not derivable from the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

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

Front-loads the decisive constraint ('FALLBACK merchant list for clients WITHOUT UI support') before any procedural detail, and every subsequent sentence carries an instruction. It is slightly dense with parentheticals and backticked names, but there is no filler.

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

Completeness5/5

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

With an output schema present, return values need not be explained, and the remaining burden — fallback condition, alternative tool, follow-up call protocol — is fully covered. Nothing an agent needs in order to invoke this correctly is missing.

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 description coverage is 100%, so both parameters are already documented, which sets a baseline of 3. The description goes beyond that by explaining how the returned selection should be threaded into subsequent calls via merchant_id, including the omit-for-own-account case — semantics the schema for this tool cannot express.

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?

States a specific verb+resource ('merchant list') and immediately qualifies its scope as a FALLBACK path for clients without UI support, which separates it from jobmojito_configuration and list_sub_merchants. An agent knows both what it returns (own account plus sub-merchants) and what it is not for.

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

Usage Guidelines5/5

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

Explicitly names the preferred alternative (jobmojito_configuration), the condition that selects this tool (client cannot render MCP App UI), and two prohibitions: do not use it to choose/switch merchants when a UI exists, and do not hand-format a merchant list as text. This is textbook when/when-not/alternative guidance.

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