Yantrikdb

YantrikDB — persistent memory

Talk to a YantrikDB memory server from the IPython kernel. Memory persists across sessions and across harnesses: what you remember here, a future session — or a different agent pointed at the same database — can recall.

Setup

Requires a running yantrikdb-mcp server on the streamable-http transport:

YANTRIKDB_API_KEY=<your-token> yantrikdb-mcp --transport streamable-http --host 127.0.0.1 --port 8420

and the same YANTRIKDB_API_KEY value in Prime Agent's environment. The server URL defaults to http://127.0.0.1:8420/mcp; override it with a yantrikdb entry under mcpServers in ~/.prime/agent/settings.json.

Usage

Discover before you call — the server defines the tool set:

import yantrikdb

for tool in await yantrikdb.list_tools():
    print(tool["name"], "-", tool["description"])

# Store a durable fact
await yantrikdb.remember(text="User prefers dark mode in the editor", importance=0.7)

# Retrieve by meaning, not keywords
hits = await yantrikdb.recall(query="what editor settings does the user like")
print(hits)

# Revise a fact without losing history (do NOT remember a contradiction)
await yantrikdb.correct(query="editor preference", new_text="User switched to light mode", reason="user said so")

Notes:

• Every tool is an async method — always await.
• Results are already-parsed Python (a dict for structured output, otherwise a string).
• Escape hatch for non-identifier tool names: await yantrikdb.call_tool("name", {...}).
• If a call raises NotEnabled, the YANTRIKDB_API_KEY environment variable is not visible to Prime Agent — set it in the shell that launches the agent.
