Wraps any\n[Agent2Agent (A2A)](https://a2a-protocol.org/) protocol server as a\nLangChain [`Runnable`](https://python.langchain.com/docs/concepts/runnables/),\nso a remote agent can be `.invoke()`d, `.astream()`ed, dropped into a\n`create_agent`/LangGraph pipeline as a node, or exposed to another agent\nas a callable tool via `.as_tool()` — the same interface you'd use for any\nlocal LangChain component.\n\nThis is useful when the agent doing the actual work runs as a separate\nservice (different language, different team, different deployment) and you\nwant to compose it into a LangChain-orchestrated system without hand-rolling\nthe A2A JSON-RPC/SSE client plumbing yourself.\n\n## Install\n\n```bash\npip install langchain-remote-a2a-agent\n```\n\nRequires Python 3.11+. Ships a `py.typed` marker — type checkers (mypy,\nPyright) and IDE autocomplete/hover (VS Code + Pylance) pick up the inline\ntype hints and docstrings automatically once installed.\n\n## Quickstart\n\n```python\nfrom langchain_remote_a2a_agent import RemoteAgent\n\nresearch = RemoteAgent(\n    name=\"research\",\n    description=\"Research agent\",\n    agent_card_url=\"http://localhost:8001/.well-known/agent-card.json\",\n)\n\nresult = research.invoke(\"What is the boiling point of nitrogen?\")\nprint(result[\"messages\"][-1].content)\n```\n\n## Multi-turn conversations\n\nPass a `thread_id` to resume the same server-side A2A context across calls:\n\n```python\nfrom langchain_core.runnables import RunnableConfig\n\nconfig = RunnableConfig(configurable={\"thread_id\": \"user-42\"})\n\nresult1 = research.invoke(\"Tell me about black holes.\", config)\nresult2 = research.invoke(\"How do they emit Hawki…","publisher":{"name":"Satya Himavanth","url":null},"homepage":"https://github.com/SatyaHimavanth/langchain-remote-a2a-agent","repository":"https://github.com/SatyaHimavanth/langchain-remote-a2a-agent","version":"1.0.0","license":null,"protocols":["a2a"],"tags":["a2a","agent","agent-to-agent","langchain","llm","multi-agent"],"pricing":null,"endpoints":[{"url":"pypi:langchain-remote-a2a-agent","type":"package_pypi","auth":null,"probeable":false}],"skills":null,"tools":null,"extra":null,"attribution":{"kind":"pypi","name":"pypi","repoUrl":"pypi","summary":"pypi","version":"pypi","description":"pypi","homepageUrl":"pypi","publisherName":"pypi"}},"derived":{"capabilities":[{"slug":"automation.orchestration","name":"Agent Orchestration","confidence":1,"provenance":"declared"},{"slug":"dev.ci-cd","name":"CI/CD & Deploy","confidence":0.848,"provenance":"derived"}],"categories":["automation","dev"],"language":"en"},"observed":{"status":"unknown","statusReason":"Distributed as a package to run locally; no network endpoint to check.","lastOkAt":null,"lastProbedAt":null,"statusComputedAt":null,"reliability30d":null,"latestObservations":[],"tools":null,"package":{"name":"langchain-remote-a2a-agent","registry":"pypi","observedAt":"2026-10-28T08:28:14.519Z","publishedAt":"2026-07-03T14:53:09.005856Z","latestVersion":"1.0.0"},"toolSurface":null,"endpointFacts":[]},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"langchain-remote-a2a-agent","url":"https://pypi.org/project/langchain-remote-a2a-agent/","firstSeenAt":"2026-09-09T23:24:58.429Z","fetchedAt":"2026-10-28T08:27:21.748Z","normalizedAt":"2026-10-28T08:27:21.748Z"}]},"firstSeenAt":"2026-09-09T23:24:58.429Z","updatedAt":"2026-10-28T08:28:14.519Z"}
