agno-agent-builder 0.1.4

Parametrizable Agno-based agent runtime — FastAPI factory with pluggable agent sources, multi-tenant headers, and LISTEN/NOTIFY hot reload.

agno-agent-builder

Parametrizable Agno runtime as a library. Build a fully configured FastAPI app for chat with hot-reloadable agents fetched from any source you plug in.

Quick start

from agno_agent_builder import create_app, RuntimeConfig, PayloadAgentSource

app = create_app(
    RuntimeConfig(
        app_name="my-runtime",
        agent_source=PayloadAgentSource(
            base_url="http://payload:3000",
            internal_secret="...",
        ),
        mcp_url="http://mcp:3001/mcp",
        database_url="postgresql://user:pass@host:5432/db",
        internal_secret="...",
    )
)

Public API

Symbol	Purpose
create_app(config)	Returns a configured FastAPI app
RuntimeConfig	Pydantic model — required + optional knobs
AgentSource	Protocol — implement async fetch_agents() -> list[AgentConfig]
AgentConfig	Normalized per-agent record (CMS-agnostic)
PayloadAgentSource	Default source for Payload CMS
build_agent, build_model, build_mcp_tools	Lower-level builders for advanced wiring
compose_instructions, DEFAULT_TOOL_PROTOCOL, DEFAULT_OUTPUT_FORMAT	Override-friendly prompt building blocks

What you get

• AgentOS REST surface (/agents, /sessions, /metrics, …)
• POST /agents/{slug}/runs SSE chat
• /health, /ready Kubernetes probes
• POST /internal/agents/reload admin endpoint
• Postgres LISTEN/NOTIFY hot reload + 5-min belt-and-braces resync
• ASGI middlewares: X-Request-ID, X-Internal-Secret auth, X-Tenant-Id → request.state.metadata

Reference consumer

The default consumer that ships in this repo lives in ../agno-agent — it wraps create_app with env-driven settings and is what runs in the agno-agent devcontainer service. ZP and nexus install this lib from PyPI and write their own thin consumer.
