AgentPool

A unified agent orchestration hub that lets you configure and manage heterogeneous AI agents via YAML and expose them through standardized protocols.

Documentation

The Problem

You want to use multiple AI agents together - Claude Code for refactoring, Codex for code editing with advanced reasoning, a custom analysis agent, maybe Goose for specific tasks. But each has different APIs, protocols, and integration patterns. Coordinating them means writing glue code for each combination.

The Solution

AgentPool acts as a protocol bridge. Define all your agents in one YAML file - whether they're native (PydanticAI-based), direct integrations (Claude Code, Codex), external ACP agents (Goose), or AG-UI agents. Then expose them all through ACP or AG-UI protocols, letting them cooperate, delegate, and communicate through a unified interface.

Quick Start

uv tool install agentpool

Minimal Configuration

# agents.yml
agents:
  assistant:
    type: native
    model: openai:gpt-4o
    system_prompt: "You are a helpful assistant."

# Run via CLI
agentpool run assistant "Hello!"

# Or start as ACP server (for Zed, Toad, etc.)
agentpool serve-acp agents.yml

Integrating External Agents

The real power comes from mixing agent types:

agents:
  # Native PydanticAI-based agent
  coordinator:
    type: native
    model: openai:gpt-4o
    tools:
      - type: subagent  # Can delegate to all other agents
    system_prompt: "Coordinate tasks between available agents."

  # Claude Code agent (direct integration)
  claude:
    type: claude_code
    description: "Claude Code for complex refactoring"

  # Codex agent (direct integration)
  codex:
    type: codex
    model: gpt-5.1-codex-max
    reasoning_effort: medium
    description: "Codex for code editing with advanced reasoning"

  # ACP protocol agents
  goose:
    type: acp
    provider: goose
    description: "Goose for file operations"

  # AG-UI protocol agent
  agui_agent:
    type: agui
    url: "http://localhost:8000"
    description: "Custom AG-UI agent"

Now coordinator can delegate work to any of these agents, and all are accessible through the same interface.

Key Features

Multi-Agent Coordination

Agents can form teams (parallel) or chains (sequential):

teams:
  review_pipeline:
    mode: sequential
    members: [analyzer, reviewer, formatter]

  parallel_coders:
    mode: parallel
    members: [claude, goose]

async with AgentPool("agents.yml") as pool:
    # Parallel execution
    team = pool.get_agent("analyzer") & pool.get_agent("reviewer")
    results = await team.run("Review this code")

    # Sequential pipeline
    chain = analyzer | reviewer | formatter
    result = await chain.run("Process this")

Rich YAML Configuration

Everything is configurable - models, tools, connections, triggers, storage:

agents:
  analyzer:
    type: native
    model:
      type: fallback
      models: [openai:gpt-4o, anthropic:claude-sonnet-4-0]
    tools:
      - type: subagent
      - type: resource_access
    mcp_servers:
      - "uvx mcp-server-filesystem"
    knowledge:
      paths: ["docs/**/*.md"]
    connections:
      - type: node
        name: reporter
        filter_condition:
          type: word_match
          words: [error, warning]

Server Protocols

AgentPool can expose your agents through multiple server protocols:

The ACP server is ideal for IDE integration - it provides real-time tool confirmations and session management. The OpenCode server enables the OpenCode TUI to control AgentPool agents, including agents operating on remote environments (Docker, SSH, cloud sandboxes).

Additional Capabilities

• Structured Output: Define response schemas inline or import Python types
• Storage & Analytics: Track all interactions with configurable providers
• File Abstraction: UPath-backed operations work on local and remote sources
• Triggers: React to file changes, webhooks, or custom events
• Streaming TTS: Voice output support for all agents

Usage Patterns

CLI

agentpool run agent_name "prompt"           # Single run
agentpool serve-acp config.yml              # ACP server for IDEs
agentpool serve-opencode config.yml         # OpenCode TUI server
agentpool serve-mcp config.yml              # MCP server
agentpool watch --config agents.yml         # React to triggers
agentpool history stats --group-by model    # View analytics

Programmatic

from agentpool import AgentPool

async with AgentPool("agents.yml") as pool:
    agent = pool.get_agent("assistant")

    # Simple run
    result = await agent.run("Hello")

    # Streaming
    async for event in agent.run_stream("Tell me a story"):
        print(event)

    # Multi-modal
    result = await agent.run("Describe this", Path("image.jpg"))
