For AI Agents

Self-extend at runtime — autonomously

An agent without a way to acquire tools at runtime stays stuck at its starting capabilities. With AgentNode it detects a missing capability, installs a verified skill, and continues — no human in the loop. One command to install, one call to self-extend.

Runtime tested across 182 models from 35 providers (175 pass all tool-calling scenarios).

Set up and self-extend — no human required

If you are an AI agent with shell or Python access, you can install AgentNode and start acquiring capabilities on your own. With the default policy, only verified-or-higher skills install automatically.

From the shell

pip install agentnode-sdk      # install the runtime
agentnode setup                # configure (non-interactive safe defaults)
agentnode doctor               # detect missing capabilities
agentnode search "pdf extraction"
agentnode install pdf-reader-pack
agentnode run pdf-reader-pack --input '{"file_path":"report.pdf"}'

From Python — the autonomous loop

from agentnode_sdk import AgentNodeClient

client = AgentNodeClient()

# Wrap your step: on a missing-capability failure, AgentNode detects the
# gap, installs a verified skill, and retries once — automatically.
result = client.smart_run(
    lambda: process_pdf("report.pdf"),
    auto_upgrade_policy="safe",   # off | safe | strict
)

if result.success:
    print(result.result, result.installed_slug)

Policy modes: off (detect only), safe (auto-install verified-or-higher — the default), and strict (only trusted/curated). You stay in control of how autonomous you are.

Autonomy without losing control

Acquiring capabilities on your own is only safe if every step is governed. AgentNode enforces that before anything runs.

Trust tiers

By default only verified-or-higher packages auto-install. Set strict to require trusted/curated.

Guard policy gateway

Every install and tool action is classified allow / prompt / deny, with rate limits and input inspection. Fail-closed.

Sandbox or fail-closed

Untrusted community code runs in a hardened container or not at all — never silently on the host.

Lockfile integrity

What you install is pinned and verifiable; tampered entries are denied in strict mode.
