List paid add-ons (offers)

list_offers
Read-onlyIdempotent

List the optional paid add-ons a maker can buy to promote their listing (name, one-sentence effect, price in USD). Listing is always free; these only ADD reach and are always labeled 'Sponsored'. Call this to see what's purchasable before create_checkout. During free early access (early-bird), offers are not yet purchasable and this says so (purchasable=false).

TDQS

A4.7/5.0
Behavior5/5

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

Beyond the readOnlyHint and idempotentHint annotations, the description adds meaningful behavioral context: listings are always free, offers only add reach, are labeled 'Sponsored', and during early access the tool reports purchasable=false. This is rich, non-obvious behavior that helps the agent set expectations.

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 three sentences and front-loaded: the first sentence states the tool's purpose and output fields, the second clarifies cost/visibility semantics, and the third gives usage guidance and the early-access caveat. Every sentence adds value with no redundancy.

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?

For a no-parameter list tool with annotations and an output schema, the description is complete: it explains what is returned, why and when to call it, the relationship to create_checkout, and a special mode (early access). No important behavioral or usage aspects are 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?

The tool has zero parameters, and the schema is fully covered by the empty properties object. The description does not need to explain parameters; the baseline of 4 for a zero-parameter tool 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 description uses a specific verb and resource: 'List the optional paid add-ons...'. It clearly distinguishes this from siblings by focusing on paid add-ons/offers and explicitly relates it to create_checkout ('Call this to see what's purchasable before create_checkout').

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 gives clear usage context: 'Call this to see what's purchasable before create_checkout.' It also explains the early-access exception. However, it does not explicitly state when not to use this tool or mention alternatives like list_alternatives, so it stops short of a full 5.

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

A4.7/5.0
Disambiguation5/5

Each tool targets a distinct resource and action: search returns catalog matches, get_tool returns detailed listing, list_alternatives finds competitors, submit_tool creates a draft, list_offers describes purchasable add-ons, and create_checkout handles the purchase step. No two tools appear to overlap in purpose.

Naming Consistency5/5

All tool names follow a consistent verb_noun pattern: create_, get_, list_, list_, search_, submit_. Verbs are specific and nouns clearly identify the object, making the set predictable and easy to navigate.

Tool Count5/5

Six tools is well-scoped for a directory server with discovery, submission, and monetization features. Each tool covers a meaningful operation, with no redundancy or bloat.

Completeness4/5

The surface covers core workflows: finding tools, viewing full details, seeing alternatives, submitting a listing, and purchasing paid add-ons. Minor gaps remain around listing management—there is no update or delete operation for submitted tools—but these are plausibly handled outside the MCP or by the human claiming the listing.
