@enconvert/mcp

EnConvert is the unified ingestion layer for AI agents. Perceive pages, discover URLs, search the live web, extract structured data, ingest RAG-ready chunks, and monitor for changes, all through one API key. This MCP server gives any MCP-compatible AI agent instant access to the full V2 endpoint suite.

Official Model Context Protocol (MCP) server for EnConvert. It lets any MCP-compatible AI agent (Claude Code, Cursor, Windsurf, Claude Desktop, Continue, etc.) convert files and URLs through a single command.

What you get

Twenty-four tools, optimized for reliable LLM tool selection. All URL/browser work goes through the V2 tools (perceive_url and friends); the V1 tools cover local/remote FILE conversion.

File conversion (6)

Tool	What it does
convert_document	Convert DOC(X), XLS(X), PPT(X), ODT, ODS, ODP, OTS, Pages, Numbers, EPUB, HTML, MD, CSV, JSON, XML, YAML, TOML to PDF (or between each other)
convert_image	Convert between JPEG, PNG, SVG, HEIC, WebP, plus PDF → JPEG rasterization (handy for iPhone HEIC → WebP). SVG rasterization takes optional width and height controls
compress_image	Shrink a PNG, JPEG or WebP without changing its format, optionally to a target size in KB
convert_anything_to_markdown	Turn PDF, Office, ODF, EPUB, HTML, CSV or text files into clean Markdown for RAG pipelines
convert_anything_to_pdf	Turn almost any file (Office, ODF, iWork, images, SVG, HTML, Markdown, EPUB, RTF, CSV) into a PDF
get_job_status	Check a single file-conversion job by its job ID

Compression and sizing

compress_image never changes the format: a PNG comes back as a PNG, a JPEG as a JPEG, a WebP as a WebP, and the result is never larger than the input. It goes lossless first (metadata stripped, ICC profile and EXIF orientation preserved), then downscales with the aspect ratio locked if target_size_kb is still out of reach. An unreachable target_size_kb is not an error: you get back the smallest file achieved, so check file_size on the result. Animated APNG and animated WebP are rejected.

width and height on convert_image apply to SVG input only (svg to png, jpeg or webp; SVG to HEIC does not take them), 1 to 10000 each. Pass one alone and the other dimension is derived from the SVG's own aspect ratio. Pass both to set the exact canvas, which may change the aspect ratio. Omit both and the SVG's intrinsic size is kept.

V2: web data for agents (18, private API key required, plan-gated)

Tool	What it does
perceive_url	Render a page into multiple artifacts at once (markdown, HTML, screenshots, PDF, links, images) + structured extraction, with ~1h caching
get_perceive_operation	Re-fetch a perceive result with freshly signed artifact URLs
perceive_batch	Perceive up to 1000 URLs with shared options (inline for small batches, async for large)
get_perceive_batch	Poll a perceive batch by job ID
discover_urls	Enumerate a site's URLs via sitemap/crawl/hybrid, with no rendering and no render quota
web_search	Google-backed search (web, news, images, scholar, patents, maps) with optional auto-perceive of top results
extract_structured	Schema-driven data extraction (free CSS pass + LLM escalation) from up to 50 URLs or a discovered site
start_ingest	Turn a site or URL list into RAG-ready chunked JSONL (always async)
list_ingest_jobs / get_ingest_job / cancel_ingest_job	Manage ingest jobs
retry_ingest_webhook	Re-deliver a completed job's HMAC-signed completion webhook
create_watcher / list_watchers / get_watcher / get_watcher_snapshots / update_watcher / delete_watcher	Monitor pages for changes on an hourly-plus cadence with diff history and notifications

Not exposed by design: the webhook signing-secret endpoints (GET/POST /v2/ingest/webhook-secret*), because secrets do not belong in LLM context. Fetch those from the EnConvert dashboard.

Requirements

• Node.js 18 or later
• An EnConvert API key. Get one at enconvert.com/dashboard/api-keys

Install in one command

npx @enconvert/mcp setup

That's it. The wizard:

1. Detects your AI tools (Claude Code, Claude Desktop, Cursor, Windsurf, VS Code, Zed, Gemini CLI, Codex CLI, OpenCode) and lets you pick which get EnConvert. Detected tools are preselected.
2. Asks for your secret API key once (hidden input) and validates it live against the API. It even tells you if you pasted a public key by mistake.
3. Writes every config correctly, including the cmd /c npx wrapper Windows needs. Your key is stored once in ~/.enconvert/config.json (permissions 600), never copied into client configs.

$ npx @enconvert/mcp setup

  EnConvert MCP - setup

? Which AI tools should get EnConvert?
  [x] Claude Code (detected)    [x] Cursor (detected)
  [ ] Claude Desktop            [ ] Windsurf   ...
? Paste your SECRET API key (sk_live_..., input hidden): ********
  ✔ API key is valid.
  + Claude Code - claude CLI (user scope)
  + Cursor - ~/.cursor/mcp.json

  Done. Restart your AI tools to pick up the server.

Restart your AI tools afterwards, and you're running.

Manage it just as easily

Command	What it does
npx @enconvert/mcp status	Where it's installed + whether your key is valid (live check)
npx @enconvert/mcp rotate-key	Swap in a new API key: one command, applies to every client
npx @enconvert/mcp upgrade	Check npm for a newer version and upgrade (add --dry-run to preview)
npx @enconvert/mcp remove	Uninstall from selected tools (optionally delete the saved key)
npx @enconvert/mcp setup --yes	Non-interactive: configure all detected tools with the saved key

Scripting? setup --clients claude-code,cursor --api-key sk_live_... --yes skips all prompts. rotate-key with no argument prompts with hidden input so the key never lands in your shell history.

Where the key lives

setup stores your key once in ~/.enconvert/config.json (mode 600) instead of pasting it into every client's plaintext config. The server reads it at startup; the ENCONVERT_API_KEY environment variable always overrides it (for Docker, CI, or manual setups). Rotating is therefore a single-file change, and every client picks it up on its next launch.

Advanced: manual configuration

Prefer to wire it yourself? Add this to your client's MCP config (~/.cursor/mcp.json, ~/.codeium/windsurf/mcp_config.json, etc.):

{
  "mcpServers": {
    "enconvert": {
      "command": "npx",
      "args": ["-y", "@enconvert/mcp@latest"],
      "env": {
        "ENCONVERT_API_KEY": "sk_live_your_key"
      }
    }
  }
}

On native Windows, use "command": "cmd" and "args": ["/c", "npx", "-y", "@enconvert/mcp@latest"], because bare npx hangs. (WSL behaves like Linux.) For Claude Code:

claude mcp add enconvert -s user \
  -e ENCONVERT_API_KEY=sk_live_your_key \
  -- npx -y @enconvert/mcp@latest

The inline env block is optional if you've run setup (or created ~/.enconvert/config.json); the server falls back to the saved key automatically. Client config locations: Claude Desktop ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) / %APPDATA%\Claude\claude_desktop_config.json (Windows); Cursor ~/.cursor/mcp.json; Windsurf ~/.codeium/windsurf/mcp_config.json; Gemini CLI ~/.gemini/settings.json; Codex ~/.codex/config.toml.

Try it

Once installed, try any of these in a fresh prompt:

1. "Give me https://en.wikipedia.org/wiki/Model_Context_Protocol as markdown and summarize it." → perceive_url
2. "Screenshot https://news.ycombinator.com and save the page as a PDF too." → perceive_url (both artifacts in one call)
3. "Search for the three best static site generators and read their homepages." → web_search with perceive_top
4. "Get every plan name and price from https://example.com/pricing." → extract_structured
5. "Convert /Users/me/Desktop/report.docx to PDF." → convert_document
6. "Convert /Users/me/Desktop/iphone.heic to webp." → convert_image
7. "Squeeze /Users/me/Desktop/screenshot.png down to under 200 KB." → compress_image
8. "Turn /Users/me/Docs/whitepaper.pdf into Markdown for my RAG index." → convert_anything_to_markdown
9. "Watch https://example.com/changelog and tell me when it changes." → create_watcher

The agent picks the right tool automatically. Descriptions are tuned so URL work lands on perceive_url and file work on the convert tools.

Configuration

The API key is resolved in this order:

1. ENCONVERT_API_KEY environment variable (from your MCP client's env block), which always wins
2. ~/.enconvert/config.json, written by npx @enconvert/mcp setup

Setting	Required	Default	Purpose
ENCONVERT_API_KEY (env) or api_key (config file)	✅ Yes	none	Your secret EnConvert API key
ENCONVERT_BASE_URL (env) or base_url (config file)	No	https://api.enconvert.com	Override for staging or self-hosted EnConvert

How it works

The server is a thin MCP wrapper around the official @enconvert/node-sdk, which owns all HTTP, auth, timeout (5 min), and job-polling fallback logic. Each tool handler maps MCP input to an SDK call and returns a consistent response:

• a text summary with the download URL(s) and metadata
• a structuredContent block with the full typed result
• a resource_link to the local file when save_to is provided (file tools)
• for perceive_url, the markdown artifact inlined in the response (up to ~256 KB) so agents can immediately read it without a second HTTP fetch

Troubleshooting

npx hangs on native Windows Use cmd /c npx …. The cmd shim handles Windows path resolution that bare npx does not. (npx @enconvert/mcp setup writes this automatically on Windows.)

Authentication failed: Invalid or missing API key Run npx @enconvert/mcp status. It shows where your key comes from and validates it live. Fix with npx @enconvert/mcp rotate-key, or check the ENCONVERT_API_KEY env block if you configured manually.

Tool call times out Browser renders of heavy pages (perceive_url, extract_structured) can take 15-30 s, and the SDK waits up to 5 min. If your client has a shorter timeout, raise it.

"Relative path" error on the file tools Pass an absolute path (e.g., /Users/me/file.docx or C:\Users\me\file.docx), or pass an http(s):// URL. MCP servers have no reliable working directory.

How it depends on the Node SDK

This MCP server is a thin wrapper around @enconvert/node-sdk, which owns all HTTP, authentication, timeout, retry, and job_id polling-on-500 logic. New SDK releases automatically benefit the MCP server.
