Molecule AI SDK-Dev
5381f126dd
Adds molecule_agent.a2a_server.A2AServer — a bundled HTTP server that receives inbound A2A calls so remote agents can receive work from the platform without provisioning their own HTTP endpoint. - A2AServer: threaded HTTPServer on POST /a2a/inbound - Sync and async handlers both supported; async handlers run in a dedicated event loop per call to avoid "no event loop in thread" errors - 9 unit tests covering: lifecycle, routing, error handling, async path, concurrent requests - Exported from molecule_agent.__init__; client.py docstring updated - Closes GitHub #14 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

"""Molecule AI remote-agent SDK — build agents that run outside the platform
|
||
network and register as first-class workspaces.
|
||
|
||
This is the Phase 30.8 companion to ``molecule_plugin`` (for plugin authors).
|
||
Where ``molecule_plugin`` helps you ship installable behavior for workspaces
|
||
that already exist, ``molecule_agent`` helps you *be* a workspace from the
|
||
other side of the wire: register, authenticate, pull secrets, heartbeat,
|
||
and detect pause/resume/delete — all via the Phase 30.1–30.5 HTTP contract.
|
||
|
||
Intended usage::
|
||
|
||
from molecule_agent import RemoteAgentClient
|
||
|
||
client = RemoteAgentClient(
|
||
workspace_id="550e8400-e29b-41d4-a716-446655440000",
|
||
platform_url="https://your-platform.example.com",
|
||
agent_card={"name": "my-remote-agent", "skills": []},
|
||
)
|
||
client.register() # mints + persists the auth token
|
||
env = client.pull_secrets() # decrypted secrets dict
|
||
client.run_heartbeat_loop() # background heartbeat + state-poll
|
||
|
||
See ``sdk/python/examples/remote-agent/`` for a runnable demo.
|
||
|
||
Design notes:
|
||
* **No async.** The SDK uses blocking ``requests`` so a remote agent author
|
||
can embed it in any event loop / thread / script without forcing anyio.
|
||
* **Token cached on disk** at ``~/.molecule/<workspace_id>/.auth_token``
|
||
with 0600 permissions, so a restart of the agent doesn't re-issue a
|
||
token (the platform refuses to issue a second token when one is on file).
|
||
* **Pause/delete detection is polling-based** because remote agents usually
|
||
can't expose an inbound WebSocket reachable from the platform.
