ByteRover CLI (brv) - The portable memory layer for autonomous coding agents (formerly Cipher)
Interactive REPL CLI for AI-powered context memory
ByteRover CLI (brv) gives AI coding agents persistent, structured memory. It lets developers curate project knowledge into a context tree, sync it to the cloud, and share it across tools and teammates.
Run brv in any project directory to start an interactive REPL powered by your choice of LLM. The agent understands your codebase through an agentic map, can read and write files, execute code, and store knowledge for future sessions.

Key Features:
brv webui)All benchmarks are run using the production byterover-cli codebase in this repository - no separate research prototype.
We evaluate on two long-term conversational memory benchmarks:
LoCoMo - 96.1% overall accuracy (1,982 questions, 272 docs).
LongMemEval-S - 92.8% overall accuracy (500 questions, 23,867 docs).
All metrics are LLM-as-Judge accuracy (%). See the paper, or self-hosted PDF for full details.
No Node.js required - everything is bundled.
curl -fsSL https://byterover.dev/install.sh | shSupported platforms: macOS ARM64, macOS x64 (Intel), Linux x64, Linux ARM64.
Requires Node.js >= 20.
npm install -g byterover-cli
brv --version
cd your/project
brvThe REPL auto-configures on first run - no setup needed. Type / to discover all available commands:
/curate "Auth uses JWT with 24h expiry" @src/middleware/auth.ts
/query How is authentication implemented?
ByteRover Cloud is a hosted platform for teams to sync, share, and manage context knowledge across projects and machines. Everything works locally by default - Cloud adds collaboration and persistence without changing your workflow.
Sign in from the dashboard, or run brv login with an API key.
Most users only need brv webui. The commands below are for advanced users and automation. Run brv --help for the full, up-to-date reference.

brv ships with operational defaults that suit most users. The brv settings command group lets you inspect and override these values.
brv settings # List all settings with current and default values brv settings list # Alias for `brv settings` brv settings get <key> # Show current and default for one key brv settings set <key> <value> # Update one key (restart required) brv settings reset <key> # Restore one key to its default (restart required)
Available keys:
| Key | Default | What it controls |
|---|---|---|
agentPool.maxSize |
10 | Maximum concurrent active projects (one agent process per project) |
agentPool.maxConcurrentTasksPerProject |
5 | Parallel brv curate / brv query tasks within a single project |
llm.iterationBudgetMs |
600000 | Wall-clock budget for the agentic loop on one task, in milliseconds |
llm.requestTimeoutMs |
120000 | Wall-clock budget for one direct LLM HTTP request, in milliseconds |
taskHistory.maxEntries |
1000 | Number of task records brv query-log view retains per project |
Raise llm.iterationBudgetMs when a single brv curate or brv query on a slow local LLM (Ollama on CPU, heavy quantization, cold model load) routinely hits the default 10-minute cap on legitimate work. Lower it on cloud providers when you want a stuck task to surface as an error faster instead of waiting out the full budget. The cap is enforced per task, not per request.
llm.requestTimeoutMs bounds one HTTP request to the LLM. A frozen Ollama or LM Studio connection aborts at this boundary and the retry layer treats it as a transient error rather than wasting the full iteration budget. The setting must satisfy llm.requestTimeoutMs <= llm.iterationBudgetMs; the daemon rejects writes that violate the rule and falls back to defaults for both keys when the file violates it at startup. Suggested presets:
| Profile | llm.requestTimeoutMs |
llm.iterationBudgetMs |
|---|---|---|
| Cloud | 120000 (2 min) | 600000 (10 min) |
| Local LLM, fast GPU | 300000 (5 min) | 1200000 (20 min) |
| Local LLM, CPU / heavy quantization | 900000 (15 min) | 3600000 (60 min) |
Settings persist in settings.json under the brv global data directory:
$XDG_DATA_HOME/brv/settings.json (defaults to ~/.local/share/brv/settings.json)~/Library/Application Support/brv/settings.json%LOCALAPPDATA%/brv/settings.jsonSet the BRV_DATA_DIR environment variable to override the directory.
Changes apply after brv restart. The daemon reads the file once at startup and does not observe file changes during runtime. This keeps every running agent on the same configuration for the lifetime of the daemon.
Example session:
$ brv settings list KEY CURRENT DEFAULT RESTART? agentPool.maxSize 10 10 yes agentPool.maxConcurrentTasksPerProject 5 5 yes taskHistory.maxEntries 1000 1000 yes $ brv settings set agentPool.maxSize 20 Setting saved. Run `brv restart` to apply. $ brv settings get agentPool.maxSize 20 (default: 10)
Every command supports --format json for scripting. Validation errors (unknown key, value out of range) exit with code 1 and a message naming the key.
brv mcp # Start MCP server brv login # Authenticate to ByteRover brv logout # Disconnect and clear credentials brv locations # List registered projects brv restart # Restart daemon brv debug # Debug mode
Run brv --help for the full command reference.

Vocabulary
- Worktree link — a subdirectory pointer to a parent project (
brv worktree)- Source — a read-only reference to another project's knowledge (
brv source)- Origin — where an indexed search result came from (
localvsshared)
ByteRover can run from a linked subdirectory without creating a nested .brv/.
projectRoot: the directory that owns .brv/config.jsonworktreeRoot: the linked worktree directory, or projectRoot when unlinkedclientCwd: the shell cwd where you ran brvWhen you run brv query or brv curate from a linked worktree, implicit defaults use worktreeRoot so scope stays stable even if clientCwd drifts deeper into the package. Explicit relative paths that you pass yourself, such as brv curate -f ./src/auth.ts, still resolve from clientCwd to match normal shell behavior.
Use brv worktree add from the project root to register a subdirectory (or sibling) as a worktree. This creates a .brv pointer file in the target directory that redirects to the parent project — the same pattern git uses for git worktree. Use brv worktree remove to unregister, and brv worktree list to inspect. To search another project's knowledge from here, use brv source add <path> (with brv source list / brv source remove to inspect or detach).
