Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 81 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name json-to-excel.

  • Pass
    Lists tools

    tools/list returned 2 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 81 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 81 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.

    19 of 19 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.

  • Not measured
    Website matches publisher

    This namespace is not a reverse domain, so the website comparison does not apply.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Fail
    Repo owner matches

    The GitHub repository owner does not match the namespace login.

  • Pass

Capabilities

Tools 2

inspect_json

Use this when the user asks what a JSON file contains, which keys or nesting it has, how many records it holds, or why it does not parse, before converting it. Takes the same file or json_text, records_path and orient as json_to_excel and returns the record count, the key paths with their types and fill rate, nesting depth, the lists inside the records, duplicate keys, an estimate of sheets, columns and cells, and suggestions (for example a records_path). Invalid JSON is reported with its line and column. Does not make a file and does not change the JSON.

Discovered
json_to_excel

Use this when the user wants to convert JSON to Excel or CSV, turn an API response or a JSON export into a spreadsheet, or flatten nested JSON into columns. Takes one attached .json file or pasted json_text, an optional records_path (e.g. data.items) and orient (records, columns, index), and how to handle lists (scalar_arrays join or rows, object_arrays sheet or json). Returns an .xlsx and a .csv download (a ZIP of CSVs when there are linked sheets), the rows, columns and cells written, the numbers kept as text, formula-like text, and a check that each cell was read back from both files. Does not accept JSON with comments, trailing commas or JSON Lines, and does not turn date text into Excel dates. Do not use for Excel to JSON or for editing a JSON file.
