Babelagent

The Babel that lets AI agents understand each other. One shared tongue for agents that were never meant to talk.

Every agent framework has its own idea of what an agent is. LangChain has Runnables with .invoke, CrewAI has Crews with .kickoff, AutoGen has agents with .generate_reply, an LLM has messages.create, a microservice has an HTTP route. None of them agree on a shape, so connecting any two means writing glue.

Babelagent is the neutral layer in between. You bring your own agents, whatever they are (a callable, an HTTP/OpenAPI endpoint, an MCP tool, a framework agent, or an LLM), and it wraps each one in a single shared interface so they can exchange messages and collaborate on a task, agent-to-agent (A2A). The value is not any single adapter. It is that once something is adapted, it works with everything else you have adapted.

The headline is adapt(): hand Babelagent almost anything and it builds the connector on the fly.

import asyncio
from babelagent import Graph

async def main():
    graph = (
        Graph()
        .node("clean",   str.strip)
        .node("shout",   str.upper)
        .node("exclaim", lambda s: s + "!")
    )
    result = await graph.run("  hello  ")
    print(result.output)   # "HELLO!"

asyncio.run(main())

Let different agents work in parallel and hand their results to each other, with barrier policies on the join:

from babelagent import Graph, adapt

g = Graph()
g.node("src",     lambda text: text)
g.node("summary", adapt(langchain_agent), after=["src"])   # a LangChain agent
g.node("labels",  adapt("https://api.example.com/classify"), after=["src"])  # an HTTP service
# merge receives {"summary": ..., "labels": ...} keyed by node name (>=2 upstreams)
g.join("merge", after=["summary", "labels"], agent=combine, barrier="all")
result = await g.run(document)

Concepts
