Context Router Python SDK
Python client for the Context Router MCP server.
Requirements
- Python 3.10+
- Node.js 20+ with a resolvable
@context-router/mcp-serverpackage, or a built server in this monorepo
Install
From the monorepo:
cd packages/sdk-python
pip install -e ".[dev]"
Ensure the MCP server is built:
cd ../..
npm run build
Quickstart
import asyncio
from context_router import ContextRouter
async def main():
async with await ContextRouter.local() as router:
flow = await router.start("Research")
await flow.set("findings", {"answer": 42})
handoff = await flow.handoff(keys=["findings"])
print(handoff.summary)
await flow.complete()
asyncio.run(main())
Use an isolated SQLite directory in tests:
async with await ContextRouter.local(data_dir="/tmp/my-router-data") as router:
...
API surface
The Python SDK mirrors the TypeScript SDK:
- High-level:
ContextRouter.local(),router.start(),router.status(),router.discover_tools() WorkflowSession:set,get,get_many,checkpoint,handoff,complete,fail- Explicit namespaces:
router.workspace,router.schema,router.workflow,router.state,router.checkpoint,router.handoff,router.step,router.agent_role
Examples
Tests
pytest
Integration tests skip automatically when Node.js or the MCP server entry is unavailable.
Server resolution
ContextRouter.local() resolves the server in this order:
CONTEXT_ROUTER_MCP_ENTRYenvironment variable- Installed npm package
@context-router/mcp-server/entry - Monorepo fallback at
packages/server/dist/index.js
