Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 336 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name upstar.

  • Pass
    Lists tools

    tools/list returned 9 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 336 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 336 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    39 of 39 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-11-03T19:50:25.46033Z, within 180 days.

  • Not measured
    Open-source licence

Capabilities

Tools 9

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).

Discovered
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.

Discovered
get_repo

One GitHub repository as Upstar sees it, the same facts as its Upstar page: stars and gains, its usual week, its star total week by week over 12 weeks, its topics and ranks, when Upstar spotted it, its latest release, license, activity and collections. Answers for every repository with an Upstar page, kept-out ones included; blocked ones have none.

Discovered
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.

Discovered
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.

Discovered
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.

Discovered
spotted_early

Repositories whose stars at least doubled since Upstar first ranked them in a topic, at any rank: when, in which topic and at which rank it first ranked them, their stars then and now. Most grown first: the same list as Upstar's Spotted early page.

Discovered
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).

Discovered
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.
