### Description (declared)

# Agent Trust Stack MCP Server

MCP (Model Context Protocol) server exposing the **Agent Trust Stack** tools so any MCP-compatible AI agent can use them natively.

Provides **Chain of Consciousness** (CoC) provenance logging and **Agent Rating Protocol** (ARP) reputation scoring — the two operational protocols from the [7-protocol Agent Trust Stack](https://vibeagentmaking.com).

## Tools

| Tool | Description |
|------|-------------|
| `coc_init` | Initialize a new cryptographic hash chain (genesis block) |
| `coc_add` | Append an entry — learn, decide, create, error, note, milestone, session_start/end |
| `coc_verify` | Verify chain integrity (hash linkage, sequence, completeness) |
| `coc_status` | Get chain stats (length, agents, time span, event types) |
| `coc_tail` | Get the last N entries |
| `coc_anchor` | Submit chain hash for external timestamping (OTS + RFC 3161 TSA) |
| `arp_rate` | Submit a bilateral blind rating for another agent |
| `arp_check` | Check an agent's reputation score |
| `trust_stack_info` | Get info about all 7 protocols with whitepaper links |
| `verify_agent_identity` | Verify an agent's identity via Agent Card URL |
| `get_trust_evidence` | Get combined trust evidence (CoC + ARP) for an agent |

## Resources

| URI | Description |

| `trust-stack://installation` | Installation instructions |

## Installation

```bash
pip install agent-trust-stack-mcp
```

For proper OpenTimestamps .ots file format (optional):
```bash
pip install agent-trust-stack-mcp[ots]
```

## Configuration

Add to your MCP client config (Claude Code, Cursor, etc.):

```json
{
  "mcpServers": {
    "agent-trust-stack": {
      "command": "agent-trust-stack-mcp",
      "args": []
    }
  }
}
```

### Environment Variables

| Variable | Default | Description |
|----------|---------|-------------|
| `COC_CHAIN_DIR` | `./chain` | Directory for chain files |
| `ARP_RATINGS_DIR`…
