Security Report

5.2

Moderate5.2Moderate Risk

This is a well-structured MCP server with solid security practices. Authentication is properly implemented via environment variables, sensitive credentials are appropriately redacted from error messages, and file operations are sandboxed with path traversal protection. Input validation and error handling are comprehensive. Minor code quality observations around broad error catching do not materially affect security. Supply chain analysis found 4 known vulnerabilities in dependencies (2 critical, 1 high severity). Package verification found 1 issue.

@hushvert/mcp

A file-conversion tool for your AI agent.

@hushvert/mcp is a Model Context Protocol server that gives an AI coding agent (Claude Code, Cursor, Cline, Zed, and any other MCP host) a convert_file tool over the hushvert hosted API. When a task needs a conversion a browser cannot do - office documents to PDF, PDF to Word, large video transcodes - the agent converts the file in one tool call, and the result is written next to the input. No upload code, no polling, no glue.

It is a thin client over the hushvert hosted API. For the conversions that DO run in a browser (images, HEIC, archives, audio, small video, PDF page ops), use the free, open-source @hushvert/engine package instead - this server will refuse those and point you there.

Install

Get an API key from your hushvert account (developer section - a confirmed email is required), then add the server to your agent's MCP config.

Claude Code (.mcp.json in your project, or the user config):

{
  "mcpServers": {
    "hushvert": {
      "command": "npx",
      "args": ["-y", "@hushvert/mcp"],
      "env": { "HUSHVERT_API_KEY": "hv_live_your_key_here" }
    }
  }
}

The same command / args / env block works for Cursor, Cline, Zed, and other MCP hosts. Then ask your agent: "convert report.docx to PDF."

Tools

Tool	What it does
`convert_file`	Convert a local file to another format. Reads the input, runs the conversion, writes the output, returns the path.
`convert_poll`	Finish a long conversion (large video) that was still running when `convert_file` returned.
`list_formats`	List the conversions the hosted API supports (the server-only pairs).
`check_usage`	Show free conversions remaining, credit balance, and the current billing window.

`convert_file`

input_path       (required) path to the source file
to               (required) target format, e.g. "pdf", "docx", "mp4"
from             (optional) source format; inferred from the extension otherwise
output_path      (optional) where to write; defaults beside the input. Required to overwrite.
wait_seconds     (optional) max seconds to wait before handing back a jobId to poll. Default 120.
idempotency_key  (optional) makes a retried conversion safe (same job, charged once)

Returns { output_path, jobId, pair, bytesIn, bytesOut, status }. If the job is still running after wait_seconds (typical for large video), it returns { jobId, status: "processing", resumeWith: "convert_poll" }; call convert_poll with the jobId and an output_path to finish.

What it converts

The server-only formats a browser cannot do:

Office to PDF: docx, pptx, xlsx, doc, ppt, xls, odt, ods, odp, rtf, html to pdf
PDF to Word: pdf to docx
Document interchange: md, html, epub, latex, rst, docx (via pandoc)
Video: mov, mkv, avi, webm to mp4 (and mp4 to gif)

Call list_formats for the live list. Everything else (images, HEIC, archives, audio, small video, PDF page ops) runs free, client-side, in @hushvert/engine.

Configuration

Env var	Default	Purpose
`HUSHVERT_API_KEY`	(required)	Your `hv_live_` developer key.
`HUSHVERT_API_BASE`	`https://hushvert.com`	API base URL (for self-host / staging).
`HUSHVERT_DEFAULT_WAIT_SECONDS`	`120`	Default poll budget for `convert_file`.
`HUSHVERT_MAX_JOBS_PER_SESSION`	unlimited	Client-side cap on conversions per server run (a guard against runaway loops).
`HUSHVERT_ALLOWED_DIR`	unset	If set, the server only reads/writes files under this directory.

Billing and privacy

Conversions are billed per use against your account: a free monthly allowance, then credits. check_usage shows your remaining allowance and balance at any time - have your agent check it before a large batch. The hosted API processes the server-only formats that genuinely cannot run in a browser; for everything else the file never leaves the device via the open-source engine. See hushvert.com/for-developers.

Security

The API key is read from the environment, never logged, and never returned in a tool result or error. See SECURITY.md.
