Plugins had nowhere to keep their own data on an agent or workspace, so Phase 5 and 6 surfaces would each have invented a side store. Both now hold an opaque Record<string, JsonValue> that Paseo stores, snapshots and hands to hooks without reading a key. Set at creation or changed with agent.metadata.update.request / workspace.metadata.update.request (top-level keys replace, null removes). Persisted on the agent and workspace records, so it survives a restart. Reaches agent.create.before (which may add to it), agent.open.before (read-only), agent.create.after and workspace.create.before/after. Gated once on server_info.features.entityMetadata; the client throws "Update the host" instead of sending to a host without it.
@getpaseo/client
TypeScript SDK for building integrations on top of a Paseo daemon.
npm install @getpaseo/client
import { createPaseoClient } from "@getpaseo/client";
const client = createPaseoClient({ url: "ws://127.0.0.1:6767/ws" });
await client.connect();
const agent = await client.agents.create({
config: { provider: "codex/gpt-5.5" },
cwd: "/Users/me/dev/storefront",
prompt: "Review the current diff and name the riskiest change.",
});
const result = await agent.waitForFinish();
console.log(result.lastMessage);
await client.close();
The public API is the package root. Imports under @getpaseo/client/internal/* are unsupported implementation details used by Paseo's own packages.
Read the SDK documentation for agents, workspaces, terminals, provider discovery, events, recipes, and the API reference. Runnable TypeScript patterns also live in examples/.
Runtime
The client needs a WebSocket implementation. Modern browsers and Node.js 22 provide one globally.
Use a WebSocket URL ending in /ws, such as ws://127.0.0.1:6767/ws. Pass password when the daemon requires authentication.
The client advertises its supported protocol capabilities by default. Optional capabilities
overrides extend or override that declaration; browser hosting must be supplied by the caller.
Connecting alone does not subscribe to agent timelines or catalog events. See the
event guide for subscription lifetimes and timeline replacements.
Stability
The high-level API exported from @getpaseo/client is the supported SDK surface. The SDK and daemon remain protocol-compatible across versions, but newly added capabilities can require a newer daemon.
