/backend email me the top Hacker News posts every morning
/backend an API that extracts line items and totals from an uploaded invoice PDF
/backend add a confidence score to the lead scoring endpoint
/backend list
Your agent describes the endpoint to Init. Init builds it as a live, typed, versioned HTTPS API. Then the agent wires it into your app: the URL goes in config, it writes a typed server-side helper, and it runs one real test call. A single endpoint can combine LLM reasoning, web search and scraping, document processing, image and voice generation, email, a database, file storage and scheduled jobs.
You need an Init API key. Create one at init.computer and set it as INIT_API_KEY.
Install
Claude Code
/plugin marketplace add init-computer/agent-kit
/plugin install init-computer@init-computer
This adds the /backend command, an init-backend skill that tells Claude when to reach for Init, and the Init MCP server. Set INIT_API_KEY in your shell before you start claude. If another plugin also defines /backend, use /init-computer:backend.
If you only want the MCP server:
claude mcp add init --env INIT_API_KEY=init_sk_... -- npx -y @init-computer/mcp
Cursor
Click Add to Cursor above, or copy cursor/mcp.json to .cursor/mcp.json. Then add the command and the rule:
mkdir -p .cursor/commands .cursor/rules
curl -fsSL https://raw.githubusercontent.com/init-computer/agent-kit/main/cursor/commands/backend.md -o .cursor/commands/backend.md
curl -fsSL https://raw.githubusercontent.com/init-computer/agent-kit/main/cursor/rules/init.mdc -o .cursor/rules/init.mdc
VS Code (GitHub Copilot)
Click Install in VS Code above, or copy vscode/mcp.json to .vscode/mcp.json. It prompts for your key. Then add the prompt file and instructions:
mkdir -p .github/prompts
curl -fsSL https://raw.githubusercontent.com/init-computer/agent-kit/main/copilot/prompts/backend.prompt.md -o .github/prompts/backend.prompt.md
curl -fsSL https://raw.githubusercontent.com/init-computer/agent-kit/main/copilot/copilot-instructions.md >> .github/copilot-instructions.md
Use /backend in Copilot Chat agent mode.
Windsurf
Add the server in Settings → Cascade → MCP servers, using the same JSON as cursor/mcp.json with your key. Then:
mkdir -p .windsurf/workflows .windsurf/rules
curl -fsSL https://raw.githubusercontent.com/init-computer/agent-kit/main/windsurf/workflows/backend.md -o .windsurf/workflows/backend.md
curl -fsSL https://raw.githubusercontent.com/init-computer/agent-kit/main/windsurf/rules/init.md -o .windsurf/rules/init.md
Codex CLI
Add codex/config.toml to ~/.codex/config.toml with your key, then:
mkdir -p ~/.codex/prompts
curl -fsSL https://raw.githubusercontent.com/init-computer/agent-kit/main/codex/prompts/backend.md -o ~/.codex/prompts/backend.md
Run it as /prompts:backend <request>.
Cline
Add the server from Cline's MCP settings using the JSON in cursor/mcp.json. Then copy cline/.clinerules into your project. The workflow runs as /backend.md.
Any other agent
Add AGENTS.md to your project root, or append it to your existing one. It covers when to use Init, how to wire endpoints in safely, and the /backend steps. Then connect the MCP server with:
{
"mcpServers": {
"init": {
"command": "npx",
"args": ["-y", "@init-computer/mcp"],
"env": { "INIT_API_KEY": "init_sk_..." }
}
}
}
