memorynode 0.7.1

Governed local memory with Python SDK, MCP server, API, CLI, and console

MemoryNode Python SDK

Synchronous typed access to the existing MemoryNode FastAPI service, plus stdio and local shared Streamable HTTP MCP. The SDK and MCP process never access SQLite or start the API.

from memorynode import MemoryNodeClient

with MemoryNodeClient("http://127.0.0.1:8000", timeout=10) as client:
    assert client.status.check().ok
    result = client.proposals.extract(
        actor_id="demo-user",
        project_id="memorynode-demo",
        content="以后回答使用中文",
    )
    memories = client.memories.search("语言偏好")

Resources:

• status.check()
• sources.get()
• proposals.create/extract/list/get/related_memories/approve/reject()
• events.get/list_recent()
• memories.search/list/get/explain/revoke/feedback/set_expiry()

Every method accepts timeout= and request_id=. The SDK sends a generated X-Request-ID by default and retains it in errors for client-side correlation; the current server does not provide end-to-end request tracing. Unknown response fields are accepted, while missing or invalid required fields raise MemoryNodeResponseError. Server failures and suspicious details are redacted.

Phase 1 compatibility methods health(), extract_proposals(), search_memories(), and explain_memory() still return JSON-compatible dicts. The MCP entry point remains memorynode-mcp (or python -m memorynode). Default discovery exposes memory_propose, memory_search, memory_get, memory_explain, memory_list, and memory_feedback. Governance tools are hidden unless true TOML booleans in local config.toml enable them.

The memorynode CLI provides init, start, stop, restart, status, doctor, mcp, data commands, and version. The 0.7.1 wheel includes the FastAPI backend and static governance console:

memorynode init
memorynode start
memorynode status
memorynode stop

No source checkout or Node.js runtime is required. API and console default to 127.0.0.1:8000 and 127.0.0.1:3000; their distinct ports are configurable by CLI, environment, or TOML. The console receives only the API origin from its runtime config endpoint, and CORS allows only the configured console origin.

Development:

py -3.13 -m pip install -e ".[test]"
python -m pytest -q
python ../../scripts/build_release.py

Related memories remain reviewer-facing candidates, not automatic conflict decisions. Expiration remains request-driven.

memorynode mcp remains the stdio default. For a shared local endpoint, first run memorynode init and store the bearer token printed once, then run:

memorynode start
memorynode mcp --transport http --host 127.0.0.1 --port 8765

Connect MCP clients to http://127.0.0.1:8765/mcp using Authorization: Bearer <token>. HTTP accepts only 127.0.0.1; it rejects a missing or invalid token before MCP handling. Existing configurations can create a replacement token with --print-token-once. Only a token hash is persisted, and mcp.log records sanitized connection/call metadata, never tokens, headers, content, queries, parameters, or responses. The static console does not yet include an MCP overview because it cannot safely read local log files.
