CLI

The UltraContext CLI watches agent session files in the background, parses events, and syncs them to the Context API in real time.

New here? Start with the Quickstart for a 2-minute setup.

Supported agents

Agent	Session files
Claude Code	`~/.claude/projects/*/.jsonl`
Codex	`~/.codex/sessions/*/.jsonl`
OpenClaw	`~/.openclaw/agents//sessions//.jsonl`

Context metadata

The daemon enriches each context with metadata you can use to filter and search:

Field	Description	Example
`source`	Agent that created the session	`claude`, `codex`, `openclaw`
`user_id`	User identifier (`DAEMON_USER_ID` or `$USER`)	`alice`
`host`	Machine hostname	`Alices-MacBook-Pro.local`
`project_path`	Project directory (Claude Code only)	`/Users/alice/Code/myapp`
`session_id`	Original agent session ID	`b1ae8187-56cb-...`
`started_at`	Timestamp of the first event	`2026-03-08T00:01:20Z`

These fields are filterable via GET /contexts and the MCP Server.
