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 463 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name jsonpad-docs.

  • Pass
    Lists tools

    tools/list returned 14 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 463 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 463 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

    42 of 43 parameters have a description (98%). 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 2026-09-30T20:20:57.447081Z, within 180 days.

  • Not measured
    Open-source licence

    No GitHub repository to ask about a licence.

Capabilities

Tools 14

check_flow

Compile a flow document (flows-v1) with the same engine the API uses, and run its tests (flow-tests-v1) against in-memory data. Returns diagnostics (with JSON pointers into the document), what the flow reads and writes, and why each failing test failed. Costs nothing and sees no data.

Discovered
check_write_rules

Compile a list's write rules with the same engine the API uses, and run their tests (a rules-tests-v1 document). Returns every diagnostic with its line and column, and for each failing test what it expected, what happened, and how each rule came out. Costs nothing and sees no data: lookups find the test document's items. Use it before saving rules.

Discovered
eval_write_rule

Check one write against a rule set, as the API would, and say whether it would be allowed, denied (403) or failed (400), which statement decided it, and (with trace) what every expression evaluated to. The write is shaped like a rule test case: action, identity, token, old, new, patch, merge, now. Costs nothing and sees no data.

Discovered
get_api_endpoint

The full contract of one REST API endpoint: parameters, headers, request body, responses and examples, and the JavaScript SDK method that calls it. Find it by id (the docs page slug, e.g. "item-restore"), by method and path (templates or concrete paths both work: "/lists/my-list/items/abc"), or by a description.

Discovered
get_cli_command

The usage, arguments and options of a jsonpad command line tool (@basementuniverse/jsonpad-cli) command, and whether it works offline. Find it by name ("rules test", "jsonpad sync-schema --dry-run") or by what it does.

Discovered
get_plan_limits

The limits of each public plan (Free, Indie, Pro, Scale): requests per month and minute, the minimum gap between requests, storage, item size, versions kept, tokens, identities, realtime connections, webhooks and flows. null means unlimited. Sizes are in bytes, rateLimit in milliseconds, prices in GBP.

Discovered
get_sdk_method

The signature, description and example of a method in the JavaScript SDK (@basementuniverse/jsonpad-sdk) or the realtime SDK, and the REST endpoint it calls. Find it by name ("restoreItem") or by what it does.

Discovered
list_api_endpoints

List the REST API endpoints an API token can use, as method, path and title. Get one in full with get_api_endpoint.

Discovered
list_docs

List the documentation pages by section, with a description of each: the table of contents.

Discovered
lookup_error

What a JSONPad API error code means, its HTTP status, and the guides that explain it. Give the numeric code (10013) or the name (QUOTA_EXCEEDED), as found in an error response's "code" and "name".

Discovered
read_doc

Read a documentation page as markdown, or one section of it. Give a page slug ("indexing"), a /docs path, a jsonpad.io URL (with or without .md, and with an optional #anchor), "sdk/jsonpad-sdk", "sdk/jsonpad-realtime-sdk", "cli/reference" or "cli/readme". Long pages are cut at a section boundary; read on with the returned nextSection.

Discovered
search_docs

Search the JSONPad documentation, the JavaScript SDK references and the command line tool reference. Returns the best-matching sections with a snippet and their jsonpad.io URL; read one with read_doc. Exact identifiers work well: error codes and names, headers, SDK methods, CLI commands, $jsonpad-var variables, "POST /lists/{listId}/items".

Discovered
validate_sync_document

Check a schema sync document (sync-v1) as far as possible without an account: against the JSON schema the API uses, the API's rules for keys and indexes, and every rule set and flow in it with their tests. Documents that reference files (rulesFile, flowFile and their tests) are checked too if the files' contents are given in files. What a sync would change needs the account: the API server's plan_schema_sync, or jsonpad sync-schema --dry-run.

Discovered
validate_token_permissions

Check an API token's permission rules against the schema the API uses, say which rule shape a broken one was meant to be, and warn about valid rules that probably don't do what was meant (rule order, restore without view, sync-schema alone, allow "*").
