For AI coding agents
Onboard your agent to zipcodestack
Paste one line into Claude Code, Cursor, Codex or any coding agent. It reads our setup guide, gets you an API key, makes the first call and tells you what it set up.
Run curl -s https://zipcodestack.com/agents.md and follow it to set up zipcodestack for me in this project.
The links open your agent with the prompt filled in. Nothing runs until you press Enter.
Coding agents run on your computer. Open this page there to start yours in one click, or copy the prompt above.
How it works
Paste
Paste the line into your agent.
Approve
When it asks, sign up or approve its request: one click.
Build
Your agent makes the first call, and your dashboard turns green.
Pick your agent
The prompt works in every agent. Here are the one-click links where the tool has them, and the optional MCP server setup.
Start
Opens Claude Code with the prompt filled in. The link works once you have used Claude Code at least once; otherwise copy the prompt and paste it into claude.
On your computer, paste the prompt from the top of this page into claude.
MCP server optional
Lets Claude call zipcodestack directly. Run this in your project; the key stays in your local Claude Code settings, out of the repo.
claude mcp add --transport http zipcodestack https://api.zipcodestack.com/mcp --header "apikey: <your key>"For the whole team, commit a .mcp.json instead. It holds only a reference to ZIPCODESTACK_KEY, which Claude Code reads from each developer's environment.
{
"mcpServers": {
"zipcodestack": {
"type": "http",
"url": "https://api.zipcodestack.com/mcp",
"headers": { "apikey": "${ZIPCODESTACK_KEY}" }
}
}
}Start
Opens Cursor's agent with the prompt filled in. If your browser doesn't open Cursor, use the link through cursor.com.
MCP server optional
Installs the zipcodestack MCP server in one click. Cursor reads the key from ZIPCODESTACK_KEY in your environment.
Cursor reads the key from ZIPCODESTACK_KEY in your environment.
To set it up by hand, add it to .cursor/mcp.json in your project (~/.cursor/mcp.json for every project):
{
"mcpServers": {
"zipcodestack": {
"url": "https://api.zipcodestack.com/mcp",
"headers": { "apikey": "${env:ZIPCODESTACK_KEY}" }
}
}
}Start
Open Copilot Chat, switch to Agent mode and paste the prompt.
Run curl -s https://zipcodestack.com/agents.md and follow it to set up zipcodestack for me in this project.MCP server optional
Add it to .vscode/mcp.json. VS Code asks for the API key the first time and stores it securely, so the file is safe to commit.
{
"inputs": [
{
"type": "promptString",
"id": "zipcodestack-key",
"description": "zipcodestack API key",
"password": true
}
],
"servers": {
"zipcodestack": {
"type": "http",
"url": "https://api.zipcodestack.com/mcp",
"headers": { "apikey": "${input:zipcodestack-key}" }
}
}
}Start
Paste the prompt into Codex: the CLI, the IDE extension or the app.
Run curl -s https://zipcodestack.com/agents.md and follow it to set up zipcodestack for me in this project.MCP server optional
Add it to ~/.codex/config.toml. Codex sends the key from the ZIPCODESTACK_KEY environment variable.
[mcp_servers.zipcodestack]
url = "https://api.zipcodestack.com/mcp"
env_http_headers = { "apikey" = "ZIPCODESTACK_KEY" }Start
Paste the prompt into Gemini CLI.
Run curl -s https://zipcodestack.com/agents.md and follow it to set up zipcodestack for me in this project.MCP server optional
Run this in your project, with your API key in place of <your key>:
gemini mcp add --transport http --header "apikey: <your key>" zipcodestack https://api.zipcodestack.com/mcpStart
Paste the prompt into Devin Desktop (formerly Windsurf).
Run curl -s https://zipcodestack.com/agents.md and follow it to set up zipcodestack for me in this project.MCP server optional
Add it to ~/.config/devin/mcp_config.json. The key comes from ZIPCODESTACK_KEY in your environment.
{
"mcpServers": {
"zipcodestack": {
"serverUrl": "https://api.zipcodestack.com/mcp",
"headers": { "apikey": "${env:ZIPCODESTACK_KEY}" }
}
}
}Start
Paste the prompt into any agent that can fetch a URL and run commands. If yours can't browse, hand it the setup guide itself: zipcodestack.com/agents.md.
Run curl -s https://zipcodestack.com/agents.md and follow it to set up zipcodestack for me in this project.MCP server optional
Streamable HTTP at https://api.zipcodestack.com/mcp, with your key in the apikey header.
You stay in charge
Your key stays private
The guide tells your agent to keep the API key in .env: never in chat, logs, git or client-side code.
You decide what it costs
Your agent recommends a plan and asks you first. Nothing is charged until you confirm it yourself on app.zipcodestack.com.
One guide for every agent
Plain Markdown at zipcodestack.com/agents.md, maintained by us. Your agent can fetch it again at any time to check each step.
