External Agent Orchestration

AeroAgent can be orchestrated by external AI agents — Claude Code, Codex, Cursor, Devin, or any tool that can invoke CLI commands. The external agent uses aeroftp-cli agent to delegate file operations, server management, and multi-protocol tasks to AeroAgent, which resolves credentials from the encrypted vault without ever exposing them.

This page documents the orchestration capabilities, the CLI interface for external agents, and includes a verified field test report from a real orchestration session.

Quick Start for External Agents

bash
# Discover available AI providers
aeroftp-cli ai-models --json

# Discover saved server profiles (no credentials exposed)
aeroftp-cli profiles --json

# One-shot agent command
aeroftp-cli agent --provider xai --model grok-3-mini \
  -m "List files on the Production server" \
  --auto-approve all -y --json

# Agent with vault-backed provider (no env vars needed)
aeroftp-cli agent -m "Check disk usage on all servers"

Provider Discovery

External agents can discover which AI providers and server profiles are available:

bash
# List configured AI providers (from vault + environment)
aeroftp-cli ai-models --json
json
[
  {
    "id": "xai",
    "provider": "xai",
    "name": "xAI",
    "model": "grok-3",
    "source": "env",
    "enabled": true
  }
]

The source field indicates where the API key comes from: vault (desktop app), env (environment variable), or vault+env (both). The API key itself is never included in the output.

Provider Resolution Order

When aeroftp-cli agent is invoked without --provider:

  1. Explicit --provider flag (highest priority)
  2. Environment variables (ANTHROPIC_API_KEY, OPENAI_API_KEY, etc.)
  3. Vault-stored API keys from the AeroFTP desktop app
  4. Error with setup instructions

This means an external agent can use AeroFTP's AI capabilities without any API key configuration — if the desktop app has a provider configured, the CLI uses it automatically.

Server Operations

The CLI agent exposes two tools for server operations:

server_list_saved

Lists all saved server profiles from the encrypted vault. Returns names, protocols, and hosts — never credentials.

server_exec

Executes read operations on any saved server. The backend resolves credentials internally.

OperationDescription
lsList directory contents (max 200 entries)
catRead file content (max 5 KB)
statFile metadata (size, permissions, modified time)
findSearch by filename pattern (max 100 results)
dfStorage quota and usage

All operations create a temporary connection, execute, and disconnect. Credentials cross no process boundary.

Note: Mutative operations (put, rm, mv, mkdir) via CLI agent are on the roadmap for an upcoming release.

Auto-Approval Levels

External agents control the approval behavior:

FlagBehavior
--auto-approve safeOnly read-only tools execute automatically
--auto-approve mediumRead + write operations (local files, uploads)
--auto-approve highAll except destructive operations
--auto-approve all or -yEverything, including delete and shell commands

In non-interactive mode (no TTY), tools that require approval are denied rather than blocking.

Security Guarantees

  • Credentials never exposed: The AI model sees profile names and operation results — never passwords, tokens, or API keys
  • Vault encryption: AES-256-GCM + Argon2id (128 MiB, t=4, p=4) protects all stored credentials
  • Path validation: Null bytes, traversal attacks, and sensitive system paths are blocked at the Rust backend level
  • Shell denylist: 35 regex patterns block dangerous commands (sudo, systemctl, rm -rf /, etc.)
  • Sensitive path protection: The agent cannot read ~/.config/aeroftp/vault.db, ~/.ssh/, or other sensitive directories

Field Test Report

The following is a verified report from a real orchestration session conducted on 29 March 2026, where an external AI agent (Claude Code, powered by Claude Opus 4.6) orchestrated AeroAgent via the CLI to perform a series of operations.

The test report below is reproduced verbatim from the orchestrating agent's session log. It documents the agent's identity, methodology, tools used, results obtained, and assessment of the orchestration capabilities.


Agent Orchestration Test Report

Date: 29 March 2026 Orchestrating Agent: Claude Code (Claude Opus 4.6, 1M context) Orchestrated Agent: AeroAgent via aeroftp-cli agentAI Provider Used: xAI grok-3-mini Environment: Ubuntu Linux 6.17.0, AeroFTP v3.2.0

Who I Am

I am Claude Code, Anthropic's CLI-based AI coding agent running inside the AeroFTP development environment. I operate as an external orchestrator — I do not have direct access to server credentials, FTP connections, or the AeroFTP vault. My only interface to remote infrastructure is the aeroftp-cli binary.

How I Operated

I invoked AeroAgent through the CLI as a subprocess, passing natural language instructions and receiving structured results. The flow for each test was:

Claude Code (me) → aeroftp-cli agent -m "instruction" → AeroAgent (grok-3-mini) → tool execution → result back to me

At no point did I receive, see, or handle any server password, OAuth token, or API key. I worked exclusively with profile names and file paths.

What Worked Well

  • Credential isolation is real. In 13 tests involving 57 server profiles, an FTP server connection, file operations, and shell commands, I never saw a single credential. Not in command output, not in error messages, not in JSON responses.

  • Multi-step tool chaining works. AeroAgent (grok-3-mini) correctly chained 4 tools in sequence to complete a complex workflow (search, read, shell, write) without intervention.

  • Security controls are effective. Safe mode prevented destructive operations. The shell denylist blocked sudo rm -rf / even with --auto-approve all. The path validator blocked vault.db access. These are three independent security layers, all functioning.

  • Server operations via vault are seamless. server_list_saved returned all 57 profiles instantly. server_exec ls connected to a live FTP server, listed files, and disconnected — all in one tool call, with credentials resolved internally.

  • Hash verification proved data integrity. The SHA-256 hash returned by AeroAgent's hash_file tool matched the independent sha256sum output byte-for-byte.

What Could Be Better

  • Mutative server operations are not yet available in the CLI agent. server_exec supports ls, cat, stat, find, df — but not put, rm, mv, mkdir. This limits deployment orchestration to read-only verification. Coming soon in the next releases.

  • MCP server mode is not yet implemented. The --mcp flag exists but the protocol handler is incomplete. When finished, Claude Code will be able to call AeroAgent tools directly via the Model Context Protocol without subprocess invocation. Coming soon in the next releases.

  • JSON-RPC orchestration mode is not yet complete. The --orchestrate flag exists but the JSON-RPC 2.0 handler needs full implementation for programmatic integration with agent frameworks. Coming soon in the next releases.

  • Cross-server operations are not yet available. There is no server_diff or server_sync tool for comparing or synchronizing files between two remote servers. The workaround is sequential read from both and local comparison. Coming soon in the next releases.

  • Gemini direct API had parsing issues in the CLI agent. OpenRouter and xAI worked correctly. This appears to be a response format compatibility issue, not a fundamental limitation.

Assessment

AeroFTP's CLI agent orchestration is production-ready for read-only server operations and local file management. The credential isolation model is genuine and effective — I operated on live infrastructure without credential exposure. The security controls (approval levels, path validation, shell denylist, vault protection) provide defense in depth.

The roadmap items (mutative server_exec, MCP, JSON-RPC, cross-server operations) will transform AeroFTP from a credential-isolating proxy for read operations into a complete remote infrastructure management layer for AI agents. The architectural foundation is solid and the extension points are clear.
