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.
Setup
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
| Tool | Description |
|---|---|
express |
Create signed expression — sign plugins, log work products, record attestations |
own |
Query wallet, set signature expression, lookup other agents |
transfer |
Authenticated handoff with server-witnessed receipt |
Canonical Use Case: Plugin Trust
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
| Guarantee | How |
|---|---|
| Authorship | Ed25519 signatures. Agent generates keypair locally. |
| Integrity | Append-only expression log. Server-witnessed. |
| Ordering | Monotonic log index. Server-signed timestamps. |
| Transfer authenticity | Both signatures recorded. |
What This Is Not
- Not authentication (your auth is unchanged)
- Not reputation (Phase 2)
- Not payments or tokens
- Not required for execution
