## Quality 92/100 (strong)

### 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

- 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
- pass `tools.annotations`: 9 of 9 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 3,363 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump
- pass `tools.hidden_text`: no hidden text in tool names, descriptions, schemas or annotations

### stability: 83 (weight 15)

- warn `stability.changes`: 11 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name
- pass `stability.new_links`: no tool change named a new site

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

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

- tools: 9, about 3,363 tokens to load them all
- tool set hash: ea36d19e8875fda490378b1b1b1c6e3c
- tools last changed: 2026-11-05T07:05:25.046Z
- badge: [![protogrid quality](https://protogrid.dev/badge/dev.upstar/upstar.svg)](https://protogrid.dev/servers/dev.upstar/upstar)

Ranks are the topic's own: when one is skipped, left_out says how many repositories Upstar does not show there and why. Page with offset (next_offset).

Repositories: exact name first, then the most stars gained this week.

- `emerging`: Small GitHub repositories (under 1,000 stars a week ago, at least 30 days old) gaining stars at least twice as fast as in a usual week, by that ratio; optionally in one topic. The same list as Upstar's Emerging page (or the topic's Emerging tab).
- `get_collection`: A collection's ranking (score = momentum and health with the collection's weights) and its rising newcomers under 90 days old: the same lists as the collection's page on Upstar.

Answers for every repository with an Upstar page, kept-out ones included; blocked ones have none.
- `list_collections`: Upstar's collections: open-source tools that do one job, or alternatives to one product, each ranked by momentum and health. Use a slug with get_collection.
- `list_topics`: Lists the topics Upstar ranks GitHub repositories in (emulation, self-hosted, Rust, MCP…): slug, name, category, description and how many repositories rank in each this week. Use a slug with topic_ranking or emerging.
- `search`: Upstar's search, the same as the site's search bar: topics by whole words (a name, slug, GitHub tag, language or keyword equal to the query, then every word of it in the topic's name, category or description) and every repository with an Upstar page (by name, description, GitHub topics and language; kept-out ones included, blocked ones apart); plain matching, no AI. Repositories: exact name first, then the most stars gained this week.

- `topic_ranking`: Ranks a topic's GitHub repositories by star velocity (stars gained ÷ √stars before) over the last 24 hours, 7 days or 30 days, with the stars each gained: the same list as the topic's page on Upstar. Page with offset (next_offset).
- `trending`: The fastest-rising GitHub repositories across every topic Upstar tracks, by star velocity or by stars gained, over 24 hours, 7 days or 30 days; new_only keeps repositories created in the last 7 days. The same list as Upstar's Trending page.
