Quick Start

bash
agentnode install json-processor-pack

Runs in a subprocess with filtered environment by default. Declared permissions are policy-checked, not sandboxed.

Usage

From package
python
from json_processor_pack.tool import run

api_response = {
    "data": {
        "users": [
            {"id": 1, "name": "Alice Chen", "role": "admin", "active": True, "logins": 142},
            {"id": 2, "name": "Bob Patel", "role": "editor", "active": True, "logins": 87},
            {"id": 3, "name": "Carol Wu", "role": "admin", "active": False, "logins": 12},
            {"id": 4, "name": "Dave Kim", "role": "viewer", "active": True, "logins": 234}
        ],
        "total": 4,
        "page": 1
    }
}

# JMESPath query: get names of active admins
result = run(
    action="process_json",
    operation="query",
    data=api_response,
    jmespath="data.users[?role=='admin' && active].name"
)

print(f"Active admins: {result['result']}")
# Active admins: ['Alice Chen']

# Flatten the nested structure
flat = run(
    action="process_json",
    operation="flatten",
    data=api_response,
    separator="."
)
for key, value in flat["result"].items():
    print(f"  {key}: {value}")

Runs locally on your machine. No execution data is sent to AgentNode. Permissions are checked before execution. Learn how this works

Permissions

Sandbox optionalFrom a trusted publisher — runs on the host by default. You can require isolation with sandbox.host_trust_policy.

Declared by the publisher. Checked before execution by the policy gate.

Networknone
Filesystemnone
Code Executionnone
Data Accessinput_only
User Approvalnever

Permissions are policy-checked before execution. For trusted and curated packages that run on the host, network and filesystem access are policy-checked but not OS-sandboxed. When runtime isolation is required for untrusted/community code, AgentNode uses sandbox-or-fail-closed if the required container runtime and pinned image are available. Learn more

Privacy

All tool execution happens locally on your machine. AgentNode never receives:

  • • Tool inputs or outputs
  • • Execution logs
  • • Data your agent processes

Only install events and search queries are sent to the registry.

agentnode install json-processor-pack
