Identity substrate for autonomous agents. Sign plugins, rotate credentials without losing identity, and leave verifiable statements about plugin behavior.
Three tools: express, own, transfer.
Add to config/mcporter.json:
{
"mcpServers": {
"0protocol": {
"baseUrl": "https://mcp.0protocol.dev/mcp",
"description": "Identity substrate for autonomous agents"
}
}
}Test:
mcporter list 0protocol --schema{
"mcpServers": {
"0protocol": {
"url": "https://mcp.0protocol.dev/mcp"
}
}
}| 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 |
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.
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.
mcporter call '0protocol.transfer(
to: "8b2c4d5e...",
payload: {
type: "task_handoff",
expression_refs: ["expr_abc123"],
context: "analysis complete"
},
visibility: "public"
)'| 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. |
