Smithery Document URL to Markdown Conversion

Use the Smithery-deployed MinerU MCP server (TypeScript version) to convert a document URL to Markdown. This skill is for URL-based input only — local file paths are not supported by the remote server.

Input

The user will provide:

1. Document URL (required): an HTTP/HTTPS URL pointing to the document
2. Instructions (optional): what to do with the converted content (analyze, summarize, etc.)

Supported formats: PDF, DOC, DOCX, PPT, PPTX, PNG, JPG, JPEG, HTML

Important Rules

1. Always use relative paths when executing shell commands. Never use absolute paths. Never cd to an absolute path before running a command — just use relative paths directly.
2. Auto-extract zip files. When the output is a zip file, automatically unzip it to the same directory (same name without .zip extension). Do NOT delete the zip file after extraction.
3. This skill only works with URLs. If the user provides a local file path, tell them to use the /convert-to-markdown skill instead.

Workflow

1. Validate input

• Confirm the input starts with http:// or https://.
• If not, inform the user that this skill only supports URLs and suggest using /convert-to-markdown for local files.

2. Convert via MCP

Call the MCP tool convert_to_markdown with the document URL:

• The server auto-detects file type and configures optimal settings (model, OCR, etc.)
• The server polls until the task completes or times out
• On success, the server returns a download URL for the result zip file

3. Download the result

After the MCP tool returns a download URL:

1. Derive the output filename from the URL (e.g., report.pdf → report.zip).
2. Download the zip file to ./temp/ using curl:

curl -L -o ./temp/<filename>.zip "<download_url>" --retry 3 --connect-timeout 30 --max-time 600 -f -s -S

3. If curl fails, report the error and provide the download URL so the user can download manually.

4. Extract & Read

After the zip is downloaded:

1. Unzip it to a directory next to the zip file (same name without .zip extension):

unzip -o ./temp/<filename>.zip -d ./temp/<filename>

2. Find the .md file(s) inside the extracted directory.
3. Read the Markdown content.
4. If the Markdown references other files (e.g. images via ![](images/xxx.png)), note their paths — these are the only other files that matter.
5. Ignore all other extracted files (JSON, content_list, middle results, etc.). Only focus on the .md file(s) and the files they reference.

5. Respond

• If the user asked for analysis: Read the Markdown content and provide a summary or answer the user's questions about it.
• If no specific instructions: Confirm conversion is complete and show the path to the extracted Markdown file(s).

Error Handling

• If the MCP tool returns an error creating the task, report the API error message.
• If the task times out, return the task_id and suggest the user call get_task_status later.
• If the task fails, report the error message from MinerU.
• If curl download fails, provide the download URL for the user to download manually.
• If unzip fails, inform the user and provide the zip file path.
