## Overview

A2A Governance Bridge MCP provides AI-powered tools via the Model Context Protocol (MCP).

## Tools

| Tool | Description |
|------|-------------|
| `verify_agent_compliance` | Verify a remote agent meets compliance requirements before allowing A2A transact |
| `authorize_a2a_transaction` | Authorize an agent-to-agent transaction after compliance verification. |
| `get_trust_registry` | Get the current agent trust registry. |
| `get_a2a_audit_trail` | Get audit trail of all A2A governance checks. |
| `cross_agent_risk_score` | Calculate composite risk score for a multi-agent workflow. |

## Installation

```bash
pip install meok-a2a-governance-bridge-mcp
```

## Usage with Claude Desktop

Add to your Claude Desktop MCP config (`claude_desktop_config.json`):

```json
{
  "mcpServers": {
    "a2a-governance-bridge-mcp": {
      "command": "python",
      "args": ["-m", "meok_a2a_governance_bridge_mcp.server"]
    }
  }
}
```

## Usage with FastMCP

```python
from mcp.server.fastmcp import FastMCP

# This server exposes 5 tool(s) via MCP
# See server.py for full implementation
```

## Wire it up — full stack

This MCP is part of the MEOK chain that turns one agent action into a fully
signed compliance event. See
[meok.ai/mcp-stack](https://meok.ai/mcp-stack) for the 6-MCP chain:

1. **bft-progress-council-mcp** — anti-loop guardrail
2. **agent-token-budget-mcp** — hard spend cap
3. **agent-content-watermark-mcp** — EU AI Act Article 50(2) watermark
4. **meok-eu-aigc-icon-mcp** — EU Code-of-Practice icon (Nov 2026 cliff)
5. **agent-audit-logger-mcp** — hash-chained audit trail
6. **a2a-governance-bridge-mcp** — fold all signatures into one signed event

Output: ONE auditor-defensible evidence event mapped to EU AI Act Articles
12 + 50, DORA Article 17, ISO 42001 clause 9 — plus a public verify URL.

```bash
# One-shot install of the governance pack
npx meok-setup --pack governance
```

Free tier: 10 calls/day per MCP. Pro tier (£79/mo): unlimited + cryptographically signed compliance attestations your auditor verifies independently.
