### Description (declared)

# Agent Capability Purchase Preflight Receipt MCP

A local evidence tool for comparing buyer-supplied AI capability offers before a human purchase decision. It blocks explicit policy conflicts, preserves incomplete feature fit for review and selects only a unique lowest-price eligible offer from the supplied manifests.

## What it creates

- `result.json`
- `capability-matrix.csv`
- `issues.jsonl`
- `CAPABILITY_PREFLIGHT.md`
- `evidence-receipt.json`

## Requirements

- Windows 11
- Python 3.11–3.14
- An MCP-compatible client
- `MCP_LICENSE_KEY` from the MCP Marketplace purchase
- Internet access for initial and periodic license verification

License verification sends only the license key and public product slug. Buyer evidence paths, contents and generated reports remain local.

## Install from a purchased source checkout

```powershell
python -m venv .venv
.\.venv\Scripts\python.exe -m pip install .
```

## MCP client configuration

```json
{
  "mcpServers": {
    "agent-capability-preflight": {
      "command": "agent-capability-preflight-mcp",
      "env": {"MCP_LICENSE_KEY": "PASTE_THE_KEY_FROM_YOUR_PURCHASE"}
    }
  }
}
```

Run the client from the folder containing buyer-authorized evidence. All supplied paths must be relative to that folder.

## Tool

`build_capability_purchase_preflight`

- `capabilities_path`: Capability-offer JSONL
- `policy_path`: Owner policy JSON
- `requirements_path`: Required-feature JSON
- `output_directory`: new output directory

The tool returns structured JSON. `ERROR` means the request could not be processed.

## CLI

The diagnostic command is unlicensed:

```powershell
agent-capability-preflight --json doctor
```

Protected commands verify the marketplace license before reading buyer files:

```powershell
agent-capability-preflight --json analyze --capabilities examples/sample-input/capabilities.jsonl --policy examples/sample-input/policy.json --requirements examples/sample-input/requirements.json --out packet
