# docconv-mcp
<!-- mcp-name: io.github.nicklee002e/docconv-mcp -->
MCP server for **[Doc_Conv](https://converter.crepe.fund)** — convert PDF / Word / Excel /
PowerPoint documents to **Markdown**, paid **per conversion with USDC on Base** via the
[x402](https://x402.org) protocol (gasless, EIP-3009). No account, no API key: the agent signs a
USDC payment and the service returns Markdown.
Why? Feeding formatted files (PDF/PPT/DOCX) straight into an LLM can cost **5–50× more tokens**
than the same content as Markdown. This lets an agent cheaply pre-convert documents before use.
## Tools
- **`estimate_conversion(file_path)`** — free price quote (`pages`, `credits`, `priceUsdc`,
`jobId`, `jobToken`). No payment, no side effects.
- **`convert_document(file_path, max_usdc=1.0, poll_seconds=300)`** — pays via x402 (rejects if the
quote exceeds `max_usdc`) and converts. Returns inline `markdown` for text documents, or a
`downloadUrl` (zip) when the document contains images.
## Install
Published to PyPI as [`docconv-mcp`](https://pypi.org/project/docconv-mcp/). Run with
[`uvx`](https://docs.astral.sh/uv/) (no install) or `pip install docconv-mcp`.
## Configuration (env)
| Variable | Description | Default |
|---|---|---|
| `DOC_CONV_AGENT_PK` | Private key of the agent's **Base wallet** (must hold USDC). Signs x402 payments. **Secret — never commit or share.** | *(required)* |
| `DOC_CONV_BASE_URL` | Doc_Conv service base URL. Override only if self-hosting. | `https://converter.crepe.fund` |
The wallet needs **USDC on Base**; gas is paid by the service's x402 facilitator (the agent needs
no ETH). Pricing is by document size: 50 pages = 1 credit = 0.2 USDC (call `estimate_conversion`
for the exact amount).
## Claude Desktop / Claude Code (`claude_desktop_config.json` or `.mcp.json`)
```json
{
"mcpServers": {
"doc-conv": {
"command": "uvx",
"args": ["docconv-mcp"],
"env": { "DOC_CONV_AGENT_PK": "0x<your-agent-wallet-private-key>" }
}
}
}
```
Claude Code one-liner:
```bash
claude mcp add doc-conv -- env DOC_CONV_AGENT_PK=0x<key> uvx docconv-mcp
```
## Example
> "Convert `~/papers/report.pdf` to Markdown."
The agent calls `estimate_conversion` to see the price (e.g. 0.3 USDC), then `convert_document` to
pay via x402 and return the Markdown. If conversion fails, the paid credit is retained on the payer
wallet for reuse.
> ⚠️ `convert_document` spends real USDC. Use `max_usdc` to cap per-call cost.
