Overview

WeChat Developer Tools MCP Server

中文

This is a Model Context Protocol (MCP) server that connects to WeChat Developer Tools via miniprogram-automator. It allows you to control the IDE and the mini-program from an MCP client (like Claude Desktop or an AI agent).

Prerequisites

  1. Node.js: Version 18+ is recommended (though it may work on older versions with some polyfills, this project is set up for modern Node).
  2. WeChat Developer Tools: Must be installed and running.
  3. Enable Automation: In WeChat Developer Tools, go to Settings -> Security Settings and enable Service Port (CLI/HTTP invocation).

Quick Start

Add the following to your claude_desktop_config.json (e.g., ~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "wechat-devtools": {
      "command": "npx",
      "args": [
        "-y",
        "wechat-dev-mcp"
      ]
    }
  }
}

Manual Installation

To install globally:

npm install -g wechat-dev-mcp

Then configure:

{
  "mcpServers": {
    "wechat-devtools": {
      "command": "wechat-dev-mcp",
      "args": []
    }
  }
}

Local Development

  1. Clone the repository
  2. Install dependencies:
    npm install
    
  3. Build and run locally:
    node index.js
    
  4. Configure Claude Desktop to point to your local file:
    {
      "mcpServers": {
        "wechat-devtools": {
          "command": "node",
          "args": ["/absolute/path/to/wechat-dev-mcp/index.js"]
        }
      }
    }
    

Available Tools

  • launch: Launch and connect to a mini-program project.
    • projectPath: Absolute path to the project.
    • cliPath: (Optional) Path to the DevTools CLI.
  • connect: Connect to an already running DevTools instance.
    • wsEndpoint: WebSocket endpoint (e.g., ws://localhost:9420).
  • navigate_to: Navigate to a page (e.g., /pages/index/index).
  • get_page_data: Get data from the current page.
  • set_page_data: Set data on the current page.
  • get_element: Get text, attributes, wxml of an element or tap it.
  • call_method: Call a method on the current page instance.
  • disconnect: Disconnect automation.

Troubleshooting

  • Connection Refused: Ensure WeChat Developer Tools is running and the Service Port is enabled in Settings.
  • Path Issues: Use absolute paths for projectPath.

//beforeyouship — LLM Cost Modeling From Your Editor
@Indiegoing

Query realistic LLM cost models without leaving your editor. beforeyouship models the **true monthly cost** of an LLM app architecture — retries, prompt caching, batch discounts, infra overhead, and 3×/10× growth — across GPT-5.x, Claude, Gemini, DeepSeek, and more. Not a token calculator: a planning tool for the design phase, before you commit to a stack. **No API key needed to try it** — demo mode covers the six free-tier models. A Pro key from [beforeyouship.dev](https://beforeyouship.dev) unlocks the full 18-model catalog. ## What you can ask - "How much will a RAG chatbot cost at 10,000 requests/day?" - "Compare Claude Haiku vs Gemini Flash pricing for my workload" - "What's the cheapest model for a multi-step agent at scale?" - "Show me current per-token prices for Anthropic models" ## Tools ### `estimate_cost` Full cost model for an architecture at a given usage level. Returns Naive / Realistic / Worst Case monthly cost per model, 3×/10× growth scenarios, and an opinionated recommendation with reasoning. ### `get_model_prices` Current per-1M-token pricing — input, output, cached input, batch — with context windows and staleness metadata. ### `list_archetypes` Seven preset architecture patterns (simple chatbot, chatbot with history, RAG pipeline, multi-model router, coding assistant, document processor, multi-step agent) used as starting points for estimates. ## Setup **Claude Code:** ​```bash claude mcp add --transport http beforeyouship https://beforeyouship.dev/api/mcp ​``` **Cursor / other clients** — add a remote server: ​```json { "mcpServers": { "beforeyouship": { "type": "streamable-http", "url": "https://beforeyouship.dev/api/mcp" } } } ​``` Add an `Authorization: Bearer bys_...` header with a Pro key for the full catalog. ## Try it > Estimate the monthly cost of a RAG pipeline at 10,000 requests/day
