Unmeasured means there is not enough evidence to decide. How these checks work

Inspect individual checks 22 recorded

Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 195 ms.

  • Pass
    Valid handshake

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

  • Pass
    Lists tools

    tools/list returned 12 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 195 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 195 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.

  • Fail
    Parameters documented

    24 of 32 parameters have a description (75%). 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 2026-10-16T10:04:35.836388Z, within 180 days.

  • Not measured

Capabilities

Tools 12

create_app_user

Add an end user to the project (for apps where each user sees only their own records). No email is sent. Then call create_app_user_session to act as that user.

Discovered
create_app_user_session

Get a 6-hour session token for an app user without email. Send it as Authorization: Bearer <session_token> to https://reqres.in/app/collections/{collection}/records, where the user only sees their own records. Real users sign in with an emailed code via /api/app-users/login.

Discovered
create_collection

Create a collection: a new resource (like a table) with its own REST endpoint at /api/collections/{slug}/records. Use one per kind of thing the app stores (tasks, users, orders). Free projects allow 3.

Discovered
create_project

Create a real hosted backend (a REST API with a persistent database) in one call, with no account or API key. Use it when the user needs to store data, persist an app or prototype, or give a frontend a live API. Returns a manage key, a read-only public key, a starter "products" collection, the base URL and a claim_url. Show the user the claim_url: signing in through it keeps the project; otherwise it is deleted after 72 hours. Free limits: 250 requests a day, 3 collections, 100 records.

Discovered
create_record

Save a record (a JSON object) in a collection so it persists. Pass the fields as data; the API returns it with an id.

Discovered
delete_record

Delete a record from a collection.

Discovered
get_record

Read one record by id.

Discovered
list_collections

List the collections in the project.

Discovered
list_logs

See recent requests to the project (method, path, status, timing), newest first. Use it to debug why an app's calls fail.

Discovered
list_records

Read the records stored in a collection (paginated).

Discovered
patch_record

Merge the given fields into a record and keep the rest, e.g. {"done": true} to tick off a task. Use this for most edits.

Discovered
update_record

Replace all of a record's fields: fields you leave out are removed. To change some fields and keep the rest, use patch_record.
