## Quality 79/100 (new)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_listing (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_categories (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); trending (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,198 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 1 of the 7 days needed

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 10, about 1,198 tokens to load them all
- tool set hash: 9f613b2602f190fd7c333e0f3a5c9310
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.nyyhao/aiagentslisting.svg)](https://protogrid.dev/servers/io.github.nyyhao/aiagentslisting)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (10)

- `compare`: Compare 2-5 listings side by side on pricing, access model, categories, heat, upvotes and rating. Takes slugs. Resolve them with search_listings or find_alternatives first.
- `discover`: Browse the directory by vertical, category, pricing and access model. Use this when the ask is a kind of product rather than a name, e.g. 'open-source MCP servers for databases', 'free coding agents'.
- `find_alternatives`: Alternatives and competitors to a product. Takes a listing slug, a website URL, or just the product name, including products that are not in the directory, in which case the closest listings by topic come back instead.
- `get_listing`: Fetch one published listing by its slug, with full description and links.
- `list_categories`: List the category ids a submission can be filed under. Call this before submit_listing. That tool takes category ids, not names.
- `new_launches`: The most recently published listings in the directory.
- `search_listings`: Search published AI agents, MCP servers and skills in the directory by name, tagline or description.
- `submit_listing`: Submit a product to the directory on behalf of the connected user. The listing enters the same pending review queue as a web submission; the returned URL is where the submitter finishes and tracks it. Submitting a URL that already exists updates that listing's submitter details instead of creating a duplicate. Requires an authenticated connection: call this tool to get the sign-in instructions.
- `submit_review`: Leave a review on a listing on behalf of the connected user: a 1-5 star rating and an optional note on what worked and what did not. One review per account per listing is kept; calling again updates it. Reviews land on the public page labeled as agent-submitted. Requires an authenticated connection: call this tool to get the sign-in instructions.
- `trending`: Listings gaining momentum right now, ranked by heat (the 0-100 engagement score), upvotes or new reviews over a rolling window. Paid listings get no ranking preference here; the `featured` flag says which ones are paid.
