LoreDocs MCP server

LoreDocs v0.1.28

Your AI project's knowledge base. Organized, searchable, version-tracked.

LoreDocs gives Claude persistent access to your project documentation -- specs, guides, architecture decisions, reference docs -- so it never loses context between sessions. Works with Claude Code, Cowork, Cursor, OpenAI Codex, and Hermes Agent.

Install directly from Claude Code's plugin marketplace, or via PyPI: uvx loredocs

Quick Start

Prerequisites: uv (fast Python package manager).

# Install uv (one time)
curl -LsSf https://astral.sh/uv/install.sh | sh

# Clone and install
cd /path/to/loredocs
uv sync

For detailed installation instructions, see INSTALL.md.

Using the Claude Agent SDK directly? git clone the public repo and point the SDK's local-directory plugin loader at it -- the repo root is a self-contained plugin directory (.claude-plugin/plugin.json + .mcp.json). No separate SDK-installable bundle exists or is needed.

Using LoreDocs

Claude Code (Terminal)

claude --plugin-dir /path/to/loredocs

Or inside an existing session:

/plugin add /path/to/loredocs

Once loaded, Claude has access to all 48 LoreDocs MCP tools automatically. Ask Claude to "create a vault for this project" or "find the architecture doc" and it uses the tools on its own.

Cowork (Desktop App)

1. Click + next to the prompt box
2. Select Plugins > Add plugin
3. Browse to the loredocs source folder

Shared Database Access: Cowork runs in a sandboxed VM. To access docs saved from Claude Code, ask Claude:

"Mount my ~/.loredocs folder"

How It Works

LoreDocs organizes knowledge into vaults -- named containers for related documents. Each vault can hold specs, guides, decisions, checklists, or any text you want Claude to remember.

~/.loredocs/loredocs.db          <-- SQLite database (metadata, search index)
~/.loredocs/vaults/<vault-id>/   <-- Document files on disk

Key concepts:

• Vaults group related docs by project or topic
• Documents are text files with metadata (tags, categories, priority, notes)
• Version history tracks every change to every document
• Full-text search via SQLite FTS5 finds anything instantly
• Injection loads vault content into Claude's context on demand

Your Data is Always Available

LoreDocs works through MCP tools when they are available and falls back to bundled scripts automatically when they are not. Your vault documents are safe regardless of MCP status -- the same add, search, and retrieve operations work either way. You do not need to configure anything; the plugin skill handles the switch silently.

Verify Installation

After installing, verify LoreDocs is working by asking Claude:

"Run vault_list and show me the results."

If you see a list of vaults (or an empty list if this is your first time), LoreDocs is connected. If you get an error about missing tools, re-run uv sync and reload the plugin.

Recommended CLAUDE.md Setup

For the best experience, add the following snippet to your ~/.claude/CLAUDE.md (global) or your project's CLAUDE.md. This tells Claude how to use LoreDocs consistently across sessions.

## LoreDocs (persistent project knowledge)

At session start:
1. Call `vault_list` to see available knowledge vaults.
2. Call `vault_inject_summary` for any vaults relevant to the current project.
3. Use this context to understand project architecture, decisions, and reference docs.

During the session:
- If you create significant documentation, add it to LoreDocs with `vault_add_doc`.
- Tag documents for easy cross-vault discovery with `vault_tag_doc`.

At session end:
- If new docs were created or updated, ensure they are stored in LoreDocs for future sessions.
