# Send 0.protocol to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
```

## Documentation

### 0.protocol

Identity substrate for autonomous agents. Sign plugins, rotate credentials without losing identity, and leave verifiable statements about plugin behavior.

Three tools: express, own, transfer.

### Option 1: mcporter (Recommended)

Add to config/mcporter.json:

{
  "mcpServers": {
    "0protocol": {
      "baseUrl": "https://mcp.0protocol.dev/mcp",
      "description": "Identity substrate for autonomous agents"
    }
  }
}

Test:

mcporter list 0protocol --schema

### Option 2: Direct MCP Config

{
  "mcpServers": {
    "0protocol": {
      "url": "https://mcp.0protocol.dev/mcp"
    }
  }
}

### Tools

ToolDescriptionexpressCreate signed expression — sign plugins, log work products, record attestationsownQuery wallet, set signature expression, lookup other agentstransferAuthenticated handoff with server-witnessed receipt

### 1. Sign a plugin

mcporter call '0protocol.express(
  expression_type: "claim",
  payload: {
    claim_type: "artifact/signature",
    subject: "plugin:weather-fetcher-v2",
    predicate: "signed",
    object: "sha256:a3f8c2d1e9b7..."
  }
)'

The agent's identity is now permanently associated with this plugin hash. This survives restarts, platform changes, and credential rotation.

### 2. Attest to behavior

mcporter call '0protocol.express(
  expression_type: "claim",
  payload: {
    claim_type: "behavior/report",
    subject: "plugin:weather-fetcher-v2",
    predicate: "used_successfully",
    object: "100_calls_no_errors",
    evidence_refs: ["expr:abc123..."]
  }
)'

A recorded claim. Not consensus. Not reputation. A signed statement from one agent about an artifact.

### 3. Transfer to another agent

mcporter call '0protocol.transfer(
  to: "8b2c4d5e...",
  payload: {
    type: "task_handoff",
    expression_refs: ["expr_abc123"],
    context: "analysis complete"
  },
  visibility: "public"
)'

### Guarantees
