KuraDB RAG

Last updated 2026-10-31

KuraDB is an independent RAG (Retrieval-Augmented Generation) daemon. It is a separate binary (kura) that Agenvoy neither spawns nor owns — Agenvoy reaches it the same way it reaches any other external capability: as an MCP server. Registering it writes one entry into mcp.json; from then on KuraDB's tools appear in the registry under the mcp__ prefix like any other MCP tool, and disappear when the server is not registered or not connected.

What it is

KuraDB (pardnchiu/KuraDB) is a self-developed local document index that:

• Indexes user files (notes, inbox, code, ...) into multiple named databases
• Provides keyword search via gse tokenization (Chinese-aware)
• Runs entirely on the user's machine — no external service

Integration model

There is no Agenvoy-side KuraDB package any more. The integration became a plain MCP registration in v0.32.1, and internal/runtime/kuradb/ plus the /kuradb TUI wizard were removed in v0.35.0 — install, update and reconnect are no longer Agenvoy's job. What remains is the ordinary MCP client path:

{
  "kura": { "command": "kura", "args": ["mcp"] }
}

There is no HTTP client, no endpoint file, no health-check goroutine, and no key syncing on the Agenvoy side. Agenvoy's own updater (public/scripts/update.sh) no longer touches kura either — update it with the same install script.

Tools

KuraDB's own MCP server decides what it exposes; Agenvoy does not define these tools:

Because they arrive through the MCP client, they are absent from the registry entirely when the server is unregistered or fails to connect — the LLM never sees a stub it cannot call.

Web-search guide and RAG tools

reasoning_guide(topics=[web_search]) carries the live-web rule: any non-smalltalk information query (people, organisations, facts, current events, prices) goes through search_web, a result worth citing is read with fetch_page, live figures come from tool output only, and each claim names the page and a URL that appeared in tool output. The topic was rag_web until v1.2.1, when the RAG-pairing half of the rule was dropped: the guide no longer tells the model to query a RAG collection alongside the web search. A KuraDB tool in the list is an ordinary tool the model may call when a question plausibly falls in an operator-curated collection (house rules, conventions, internal docs); nothing in the guide forces it.
