semos-agentura-core

Shared MCP + A2A framework every Semos Agentura agent builds on. An agent is a BaseAgentService subclass plus a list of tools; this package turns that into a FastAPI service speaking both protocols.

Install

pip install semos-agentura-core

Minimal agent

from semos.agentura.core import (
    AgentTool,
    BaseAgentService,
    SkillDef,
    agent_tool,
    create_app,
)


@agent_tool(read_only=True)
async def my_tool(param: str) -> str:
    """Does something useful with param."""
    return f"Result: {param}"


class MyAgentService(BaseAgentService):
    @property
    def agent_name(self) -> str:
        return "My Agent"

    @property
    def agent_description(self) -> str:
        return "Does something useful."

    def get_tools(self) -> list[AgentTool]:
        return [my_tool]

    def get_skills(self) -> list[SkillDef]:
        return [SkillDef(id="my-skill", name="My Skill", description="...")]

    async def execute_skill(self, skill_id, message, *, task_id=None) -> str:
        return "result"


app = create_app(MyAgentService())

Serve it with uvicorn module:app. create_app mounts MCP at /mcp/sse and A2A at /a2a (REST) and /a2a/rpc (JSON-RPC), and serves the agent card at /.well-known/agent-card.json.

What it provides

Tool input schemas are the raw MCP inputSchema (LangChain 1.0 accepts raw dicts) and are validated with jsonschema, so oneOf/anyOf/const/enum are enforced as published.
