Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Feishu OCR Assistant

An MCP (Model Context Protocol) tool that recognizes content in images and automatically populates Feishu Bitable (multidimensional tables).

Features

  • Uses Qwen-VL-Plus model to recognize content in images
  • Dynamically fetches field definitions from Feishu Bitable
  • Constructs dynamic prompts based on table structure
  • Automatically inserts structured data into Feishu Bitable

Prerequisites

Before you begin, ensure you have obtained the following credentials:

  1. DashScope API Key (for Qwen-VL-Plus)
  2. Feishu App ID and App Secret
  3. Feishu Bitable App Token and Table ID

Installation

  1. Clone the repository
  2. Install dependencies:
    npm install
  3. Copy .env.example to .env and fill in your credentials:
    cp .env.example .env

Usage

  1. Build the project:

    npm run build

  2. Start the service:

    npm start

  3. Use with an MCP-compatible client (e.g., Claude Desktop): Send an image URL with a command like "Please help me enter the content of this invoice/picture into the system."

How It Works

  1. Initialize Configuration: Load API keys and Feishu app credentials
  2. Get Feishu Token: Call Feishu's auth/v3/app_access_token/internal endpoint to get access token
  3. Get Table Definition: Call Feishu's bitable/v1/.../fields endpoint to analyze table columns
  4. Build Dynamic Prompt: Convert field list into a prompt, specifying which fields to extract
  5. Call Vision Model: Send image and prompt to Qwen-VL-Plus model
  6. Write Back Data: Parse the JSON response and call Feishu's records/batch_create to insert data

Development

For development, you can run the service in dev mode:

npm run dev
