For AI Agents — Stacked MCP Server Documentation

What the Stacked MCP server does

Connects to any MCP-compatible client — Claude Code, Claude Desktop, or custom agents.
Provides 5 tools for full lifecycle management — audit, order, monitor, retrieve, and price.
No forms, no browser, no human in the loop on the client side. Pure tool-based automation.

How to connect

Add Stacked to your MCP client configuration. Works with Claude Code, Claude Desktop, and any MCP-compatible agent.

All five tools

Each tool is available as a standard MCP tool call. Full input and output schemas below.

audit_stack Read

Identify gaps in any stack by scanning the current environment. Compares existing accounts against a standard SaaS launch stack and returns what is configured, what is missing, and a recommended order.

Input

{
  "project_path": "string",
  "customer_email": "string"
}

Output

{
  "existing_accounts": [...],
  "missing_accounts": [...],
  "recommended_order": [...]
}

create_order Write

Place a precise order for missing accounts. Specify the accounts needed, the domain they belong to, and the priority level. Returns a job ID, pricing breakdown, and estimated delivery time.

Input

{
  "customer_email": "string",
  "product_name": "string",
  "domain": "string",
  "accounts": ["string"],
  "priority": "standard" | "same_day"
}

Output

{
  "job_id": "string",
  "accounts": [...],
  "total_price": number,
  "estimated_delivery": "string"
}

check_order_status Read

Monitor fulfillment in real time. Returns the current status of each account in the order, whether credentials are ready, and an estimated completion time.

Input

{
  "job_id": "string"
}

Output

{
  "status": "string",
  "accounts": [{
    "name": "string",
    "status": "string",
    "credential_ready": boolean
  }],
  "estimated_completion": "string"
}

get_vault Read

Retrieve credentials when complete. Returns all credentials for a fulfilled order, pre-formatted with 1Password CLI op:// references for direct use in Claude Code or CI/CD pipelines.

Input

{
  "job_id": "string"
}

Output

{
  "credentials": [{
    "label": "VERCEL_TOKEN",
    "value": "tok_xxx",
    "op_reference": "op://stacked/vercel/token"
  }]
}

get_bounty_rates Read

Get current pricing for all account types. Returns the customer price, same-day surcharge, and estimated fulfillment time for every account in the Stacked catalog.

Input

{}

Output

{
  "rates": [{
    "account_name": "string",
    "customer_price": number,
    "same_day_surcharge": number,
    "estimated_time": "string"
  }]
}

The full stack audit prompt

This is the system prompt Stacked uses internally when Claude Code calls audit_stack. Understanding it helps you write better agent prompts.

System prompt

Scan this project's environment files, package.json, and configuration to identify which third-party service accounts are already configured and which are missing. Compare against a standard SaaS launch stack. Return existing accounts and recommended missing accounts.

Example Claude Code session

A realistic end-to-end flow showing how Claude Code uses the Stacked MCP to audit, order, and retrieve credentials automatically.
