🔥 Supercharge Your Debugging
operative.sh's MCP Server unleashes LLM-powered agents to autonomously execute and debug web apps directly in your code editor.
⚡ Features
This weapon in your development arsenal transforms your Code IDE experience (Cline, Cursor):

# 1. Get your API key at operative.sh
# 2. Run the installer
bash -i <(curl -LSf https://operative.sh/webevalqa/install.sh)
# 3. Unleash the agent in Cursor Agent Mode with web_app_ux_evaluator (may have to restart Cursor)
🛠️ Install in Cursor Agent with Single Command
API_KEY="your-api-key-here" && jq --arg k "$API_KEY" '.mcpServers["web-eval-agent"]={"command":"uvx","args":["--from","git+https://github.com/Operative-Sh/web-eval-agent.git","webEvalAgent"],"env":{"OPERATIVE_API_KEY":$k}}' ~/.cursor/mcp.json > ~/.cursor/mcp.json.tmp && mv ~/.cursor/mcp.json.tmp ~/.cursor/mcp.json
🛠️ Manual JSON Installation
- Run
uvx --from git+https://github.com/Operative-Sh/web-eval-agent.git webEvalAgent
with no api key first since Cursor doesn't wait for our deps to download! - On startup, kill and then update your relevent MCP JSON:
"web-eval-agent": {
"command": "uvx",
"args": [
"--from",
"git+https://github.com/Operative-Sh/web-eval-agent.git",
"webEvalAgent"
],
"env": {
