Open-source runtime that runs and supervises coding agents, locally or in cloud sandboxes.
agentproto is a local daemon plus a CLI. It starts coding agents such as Claude Code, Codex and opencode as background sessions, lists them in one place, and lets you attach a check (your tests, or a reviewer agent) that runs when an agent finishes a turn. If you like an operating-system analogy, it works like an OS layer for agents: session lifecycle, scheduling, permissions and tasks. It is not an operating system: no kernel, and no isolation unless you ask for a sandbox.
- Run agents the same way. Start, message, watch, and stop agent sessions with the same commands. Claude Code, Codex and opencode are the adapters we use and test day to day; the other adapters (Hermes, Gemini, Grok CLI and more) exist at varying maturity.
- Checked work, opt-in per session. Attach a gate (a shell command such as
your test suite, or a judge agent) with
agentproto policy attach. If the gate fails the policy endsblocked, or, if you set--on-fail-nudgeor--on-fail-max-retries, the session is re-prompted (2 times by default) before it isblocked. With--then commit, a green gate stages a commit that waits for your explicitpolicy ack --approve(requireHumanAckdefaults to on). Nothing is gated unless you attach a policy. - Locally or in cloud sandboxes you connect. The daemon runs on your
machine, and the agent processes it starts run with your own user rights. If
the daemon or the machine stops, nothing runs, wakes or is checked. A
session can instead run in a sandbox box (
sandboxoption ofagent_start, providers such as e2b, with your own account). agentproto is not a hosted service. - Keep the tools you have. It drives the agent CLIs you already use, nothing to rewrite. Agents can also start and supervise other agents.
- And a toolbox around them. Author tools as files and serve them, import MCP servers and hand them to the agents it runs, open tunnels, drive browsers, schedule workflows and cron runs.
The daemon is the most mature surface of something bigger: agentproto is an open set of file formats (the AIP specs) that describe agent components (tools, skills, agents, knowledge, workflows, policies) as plain files with a declared contract, and this repo is the TypeScript runtime that loads and runs them and projects them into hosts (CLI, HTTP, MCP, Mastra, Vercel AI SDK). Most of the specs beyond the daemon are early; see "What's live vs. roadmap" below.
Status: 1.x, APIs stabilising. Expect minor breaking changes between releases.
Install, daemon start and adapter install were tested on a clean HOME and npm
prefix (macOS arm64, Node 24, @agentproto/cli from npm). The first session
stopped at the missing credential (step 3), so steps 3 to 4 and the gate below
follow the CLI's own error text and docs, not a full run with a model.
# 1. install the CLI and the adapter for the agent you want to drive
npm i -g @agentproto/cli
agentproto install claude-code # installs the adapter package and its ACP bridge
# 2. start the daemon (foreground, http://127.0.0.1:18790 by default)
agentproto serveIn a second terminal:
# 3. give the adapter a credential. A new install has none and the first
# session fails with `missing_auth_credential` until you do one of:
claude setup-token # Claude subscription
agentproto auth provider set anthropic <your-api-key> # or an API key
# 4. first session
agentproto sessions start claude-code --cwd . --prompt "refactor the payments module"
agentproto sessions --watchThen gate it. A gate fires when the session's turn ends, so attach it
before the turn ends, or send another prompt afterwards
(agentproto sessions prompt <id> --prompt "..."); until then the policy
stays watching. Gate commands run under a default-deny allowlist, so first
allow them in <workspace>/.agentproto/allowed-commands.json, where
<workspace> is the directory you started agentproto serve in (without it
the policy goes straight to blocked with not in allowlist):
{ "version": 1, "commands": ["pnpm", "git"] }--then commit requires --commit-path and --commit-message; <id> is the
session id shown by agentproto sessions:
agentproto policy attach --session <id> --then commit \
--commit-path src --commit-message "refactor payments" \
-- pnpm test
agentproto policy status <policyId>
agentproto policy ack <policyId> --approve # or --rejectSee docs/cli/guides/gates.md for gates in depth
and agentproto.sh for the pitch. A one-line bootstrap
script also exists (scripts/bootstrap/install.sh on macOS/Linux,
install.ps1 on Windows).
This repo ships two very different things under one name:
- Tier 1, live: the daemon, the CLI, durable policy gates, nested
orchestration with role gating, fan-in monitoring, workflows/cron, and an MCP
surface on the daemon itself. Adapters: Claude Code, Codex and opencode are
the ones used and tested hands-on; the other adapters in
adapters/are of varying maturity. - Tier 2 — the wider AIP spec family: 72 numbered specs live in
agentproto/agentproto. Most
reference-implementation packages beyond Tier 1 are
0.1.0-alphascaffolding — real schemas, real intent, not yet operational software.
Full breakdown: https://agentproto.sh/features. If you find a Tier 2 claim anywhere that reads as shipped, please file an issue — that split is the contract.
The adapter contract is small: declare models[] and modes[] via an
AIP-45 manifest, implement the lifecycle verbs, and reuse the shared
provider-kit primitives (creds, catalog entry, setup/status tools). Obvious
gaps: Cursor (agent CLI, ACP-capable — not verified end to end), aider,
goose, cline, Continue. See adapters/claude-code
for a complete reference implementation, and look for good first issue
labels in the tracker.
packages/vscode contains the private agentproto-vscode extension: local
operational views for daemon sessions and permissions, plus commands to manage
agents from the editor. Every Releases
asset is built in CI, never committed to the repo:
- Dev builds — every push to
maintouchingpackages/vscodepublishes a prerelease VSIX taggedvscode-dev-<sha>, for grabbing the bleeding edge. - Official releases — a "Version Packages" PR merge that included
vscode changes publishes a versioned VSIX tagged
vscode-v<version>, same cadence as every other package's release.
Install either through VS Code's Extensions: Install from VSIX... command.
To build one yourself instead:
cd packages/vscode
pnpm package
unzip -t agentproto-vscode-*.vsixSee packages/vscode/README.md for
development and verification commands.
The repo is organised into five layers, each a sibling subtree under
packages/ or adapters/.
@agentproto/runtime is the long-running gateway that turns a workspace into
a live AIP runtime: session management, an MCP server, an HTTP transport, the
HEARTBEAT autonomy loop (deprecated: use cron or routines), and append-only conversation persistence.

All agent-CLI adapters share the provider-kit primitives: makeSetupTool
(single-field or multi-field creds), computeStatus, AdapterCatalogEntry, and
makeCredsStore. mastra-agent is the odd one out: every other adapter wraps
an external agent CLI, whereas mastra-agent is ours end to end — an
AGENT.md run as a live Mastra agent (our loop, our models), spawned by the
daemon like any arm or standalone via agentproto-mastra acp.
