Anlyon alternative

3 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

    Why it is in this group

    • The name "convert_file" says "convert": a word for a change.
    Description, as the server wrote it
    End-to-end conversion of a remote file: fetches 'source_url' (with SSRF protection), uploads it to FileConvert, and starts a conversion from 'source_format' to 'target_format' (named by extension, e.g. png → webp, docx → pdf). Returns the conversion 'job_id' and the uploaded 'file_id'. Poll progress with get_job_status(job_id); when the status is Completed, call get_download_url(job_id) for the result. Conversions consume account credits. For a file you hold locally, use upload_file + start_conversion instead.
  • start_conversionStarts a conversion of a file that is already in FileConvert (a 'file_id' from upload_file or from an earlier job) from 'source_format' to 'target_format' (named by extension).No findings

    Why it is in this group

    • The name "start_conversion" says "start": a word for a change.
    Description, as the server wrote it
    Starts a conversion of a file that is already in FileConvert (a 'file_id' from upload_file or from an earlier job) from 'source_format' to 'target_format' (named by extension). Returns the 'job_id' to poll with get_job_status. Conversions consume account credits.
  • upload_fileUploads file bytes (base64) into FileConvert and returns a 'file_id'.No findings

    Why it is in this group

    • The name "upload_file" says "upload": a word for a change.
    Description, as the server wrote it
    Uploads file bytes (base64) into FileConvert and returns a 'file_id'. Use this when the file is not reachable by URL, then call start_conversion(file_id, source_format, target_format). For files reachable over http(s), convert_file is a single call instead.

  • get_balanceReturns the credit balance of the signed-in account, plus where to get more.No findings

    Why it is in this group

    • The name "get_balance" says "get": a word for reading.
    Description, as the server wrote it
    Returns the credit balance of the signed-in account, plus where to get more. Every conversion costs credits; call this when a conversion fails with 'no credits' or when the user asks how many conversions they have left.
  • get_download_urlReturns the download URL of a converted file.Reads private dataReads text others writeNo findings

    Why it is in this group

    • The name "get_download_url" says "get": a word for reading.

    What it can reach

    • private-dataThe description's first sentence says "return" and "file": it reads files.
    • private-dataThe input names a file (input.file_id), and the tool reads: it reads files.
    • untrusted-inputThe name "get_download_url" says "get" and "url": it reads web pages, which anyone can write.
    • untrusted-inputThe description's first sentence says "return" and "url": it reads web pages, which anyone can write.
    Description, as the server wrote it
    Returns the download URL of a converted file. Pass 'job_id' (conversion uid) to resolve the converted file of a finished conversion, or 'file_id' to download a known file uid directly. The URL needs no authentication (the unguessable file id is the capability), so it can be handed to the user or another system as-is. It stops working when the file's retention ends — about one hour after conversion by default — so download or share it promptly.
  • get_job_statusReturns the current status of a conversion job.No findings

    Why it is in this group

    • The name "get_job_status" says "get": a word for reading.
    Description, as the server wrote it
    Returns the current status of a conversion job. Statuses: Pending → Processing → Completed or Failed (Failed includes the reason). Poll every 2–3 seconds after convert_file / start_conversion; when Completed, call get_download_url. Also returns the full conversion object, which includes the converted file uid once the job has finished.
  • get_upload_urlReturns instructions for uploading an agent-local file into FileConvert.Reads private dataReads text others writeNo findings

    Why it is in this group

    • The name "get_upload_url" says "get": a word for reading.

    What it can reach

    • private-dataThe description's first sentence says "return" and "file": it reads files.
    • untrusted-inputThe name "get_upload_url" says "get" and "url": it reads web pages, which anyone can write.
    Description, as the server wrote it
    Returns instructions for uploading an agent-local file into FileConvert. FileConvert does NOT use presigned upload URLs; instead you upload the file bytes directly to the gateway as a multipart/form-data POST. The response gives the exact URL, HTTP method, form field name and required Authorization header. After uploading you receive a file object whose 'uid' can be passed to a conversion. If your file is reachable over http(s), prefer convert_file(source_url, target_format) which fetches and uploads it for you. Works without a token (the upload itself needs one).
  • list_formatsReturns the file formats FileConvert can read and write, along with the format-type categories (image, video, document, audio, …).Reads private dataNo findings

    Why it is in this group

    • The name "list_formats" says "list": a word for reading.

    What it can reach

    • private-dataThe description's first sentence says "return" and "file": it reads files.
    Description, as the server wrote it
    Returns the file formats FileConvert can read and write, along with the format-type categories (image, video, document, audio, …). Use this first to discover valid 'format_type', 'source_format' and 'target_format' identifiers before calling convert_file. Each format includes its numeric id, name, file extension and description. Optionally pass 'format_type' to filter to a single category. Works without a token.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged outbound.

Reads private data3
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write2
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

  • WarnThe whole server

    The endpoint served tools/list without credentials, and the list has 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.

    Matched text

    https://file-convert.online/api/mcp/v1/mcp: tools/list returned 8 tools to an anonymous client, including convert_file (write), start_conversion (write), upload_file (write)

    What this check looks for

Findings

Matches of fixed checks, with the text they matched.

No check matched anything in these tool definitions. That is not a safety guarantee.

History

Changes to its tool definitions and to its remote endpoint, newest first.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as fileconvert. Review it before you use it.
