Common questions
Is Ocr safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
You need to fill in: Authorization
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 3 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?

🪙 PennyOCR MCP server
A remote Model Context Protocol server that gives any agent document-reading eyes: PDFs and images by URL → markdown (tables preserved) or plain text, with exact cost reporting and hard spend caps.
Hosted at `https://mcp.pennyocr.com` — nothing to install:
{"mcpServers": { "pennyocr": { "url": "https://mcp.pennyocr.com", "headers": { "Authorization": "Bearer pk_live_..." } } } }
Keys are free (first 100 pages free) at pennyocr.com/dashboard. Clients that can't set headers: https://mcp.pennyocr.com/?key=pk_live_...
Tools
| Tool | Input | Output |
|---|---|---|
read_document | {url, pages?, output?, max_pages?, max_cost_usd?} | {content, pages, cost_usd, citations[]} |
estimate_cost | {url, pages?} | page count + exact cost — free |
check_balance | {} | remaining credits + free-tier allowance — free |
The cost caps refuse *before* any processing, with the numbers — so autonomous agents can reason about spend ("200 pages, $0.15 — proceed") and can never run past a prepaid balance.
Transport
Streamable HTTP (JSON-RPC 2.0 over POST), stateless. This repo is the complete server — a single Cloudflare Worker (worker.js) proxying the PennyOCR API.
Pricing: $0.75 per 1,000 pages · pennyocr.com/pricing.txt · Agent onboarding: pennyocr.com/llms.txt
Cursor plugin
This repository includes a Cursor plugin manifest at .cursor-plugin/plugin.json and a plugin-specific mcp.json. In the plugin configuration, set PENNYOCR_API_KEY to your own API key from https://pennyocr.com/dashboard/. The repository contains only a variable placeholder, never a live key. Document reading uses your PennyOCR credits; use cost estimates and spend caps as appropriate. The separate .mcp.json uses Cursor environment-variable interpolation for direct MCP configuration.
