Your AI is brilliant. Its memory is fragmented.

Every new chat drops project history, decisions, research, and hard-won context. Vendor memory helps inside one product, then disappears when you move to another agent. Traditional file connectors can open a note when the path is already known; vector search can find a similar paragraph; neither is a complete memory system.

enquire-mcp turns Obsidian into the memory database for your agents

One install turns your existing vault into a persistent, queryable knowledge database for any MCP-compatible agent. It indexes locally, retrieves across formats, ranks by lexical + semantic + graph evidence, and returns the source context an agent can cite. The original files remain readable and editable without enquire-mcp.

Memory you own. Most conversation-memory products extract facts from chats into a separate store. enquire-mcp starts from the knowledge you deliberately kept: Markdown, frontmatter, wikilinks, PDFs, Canvas, and Bases. Recall is grounded in source material rather than a hidden paraphrase.

Document intelligence without a data migration. PDFs enter the same local hybrid-search path as Markdown and return page citations; OCR can recover scanned pages. Canvas becomes a typed graph. Dedicated tools run the supported Dataview LIST/TABLE subset and supported Obsidian Base filters instead of treating those formats as opaque attachments.

Freshness, not timeless recall. Every search hit can carry age_days and stale; optional recency weighting helps agents prefer newer knowledge and re-check old facts instead of confidently repeating them.

What makes enquire-mcp different:

1. Freshness-aware, cited recall. Search results retain source paths and expose age/staleness; PDF hits keep page citations. Optional recency re-ranking helps agents prefer fresh knowledge and re-verify old facts.
2. Read-only by default. Seven write tools stay invisible until --enable-write; privacy filters and exact-Origin HTTP admission reduce the exposed surface.
3. Obsidian-native document intelligence. Markdown/PDF hybrid recall is complemented by typed Canvas parsing, Dataview-style LIST/TABLE queries, and supported Base-filter execution.
4. Full-stack local retrieval. Hybrid BM25 + TF-IDF + multilingual embeddings fused via RRF, with an optional BGE cross-encoder reranker and per-signal scores; HNSW + int8 quantization scale the dense path.
5. A clear data boundary. enquire initiates zero outbound calls during serve and sends no telemetry. It returns requested context only to the MCP client you connect; that client's own privacy terms govern any later cloud processing. See the exact privacy policy.
6. Vendor-neutral memory. Your source knowledge remains in portable files. Switch agents or model providers without rebuilding a proprietary memory silo.

🏆 Why enquire-mcp is the complete Obsidian intelligence stack

Most alternatives solve one layer: an in-app similarity panel, a capable search engine, or MCP file access. enquire-mcp combines the full local retrieval ladder, agent orchestration, rich-document coverage, freshness, safety, and release discipline in one package.

_{✅ = the complete row is built in. ✕ = the complete combination was not documented on the reviewed public product surface; a project may implement part of the row or add it later. Review date: 2026-07-30. Exact source snapshots and row-by-row boundaries: competitive evidence.}

That is the TOP-1 thesis: one source of truth, one local intelligence layer, every agent — without reducing your knowledge to a cloud memory blob.

enquire-mcp is the open-source backend for Karpathy-style LLM Wikis on top of the Obsidian vault you already own: knowledge that compounds, with every answer traceable to source.

⚡ Quick start

npm install -g @oomkapwn/enquire-mcp
enquire-mcp serve --vault ~/Documents/Obsidian\ Vault

Drop into any MCP client:

{
  "mcpServers": {
    "obsidian": {
      "command": "npx",
      "args": ["-y", "@oomkapwn/enquire-mcp", "serve", "--vault", "/path/to/vault"]
    }
  }
}

Prefer a reviewable desktop bundle? Use MCPB Basic

The v4.0.0-rc.7 GitHub Release provides enquire-mcp-basic-4.0.0-rc.7.mcpb together with its checksum, inventory, SBOM, notices, and provenance. The bundle packages the server JavaScript and ordinary JavaScript dependencies; a compatible MCPB host must supply Node.js 22.13 or newer. Open it in that host, review the manifest, and choose the one vault directory the host may expose.
