Common questions

Is Knowledge safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: KNOWLEDGE_OPEN_NOTEBOOK_PASSWORD

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 10 days ago, and the latest version (0.2.1) reached the registry 16 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

Knowledge

Made by [Seaynic Labs](https://seayniclabs.com). Need tools like this built around your own systems? We do that.

Knowledge lets an AI assistant search, read and write the notes in your self-hosted Open Notebook, and comes with skills that teach it to do that work well: meeting notes, decision records, weekly reviews and source-backed research.

It is a bundle: tools, skills and instructions in one install. The tools are one server made of modules. You switch on the modules you use. New modules arrive switched off, so an update never changes what your assistant can do until you choose to.

Security card
NetworkOnly the Open Notebook server you configure (KNOWLEDGE_OPEN_NOTEBOOK_URL). Open Notebook fetches the links you add, not Knowledge. Nothing else, no telemetry.
FilesReads its config file (~/.config/knowledge/config.toml). Reads a local file only when you name it in open_notebook_add_source, and only after you approve it (the file goes to your Open Notebook server). Writes one local approval log (~/.local/state/knowledge/approvals.jsonl).
SecretsAPI keys and passwords come from your environment or config file. They are never tool arguments and never returned to the model.
Read-only tools6: open_notebook_notebooks, open_notebook_search, open_notebook_notes, open_notebook_note_get, open_notebook_source_get, knowledge_modules
Needs your approvalopen_notebook_note_create, open_notebook_add_source: you approve each write in your app, or pre-approve notebooks in settings (not for local files). The AI cannot approve for you.
Startup costabout 4,600 tokens (8 tools, 7 skill prompts)
ChangesTool descriptions are locked by hash (tool-manifest.lock.json); CI fails if they change silently.

Skills

SkillWhat it doesSource
getting-startedChecks the settings, runs the first calls, explains approvals and errorsSeaynic Labs (MIT)
research-with-sourcesAnswers from your notebooks, cites each claim, flags sources that disagreeSeaynic Labs (MIT)
weekly-reviewDone, open and next-week items from the notes you changed this weekSeaynic Labs (MIT)

icm-architectOrganises a knowledge base as a folder structure that agents can walkJake Van Clief (MIT), credits
obsidian-markdownObsidian-flavoured Markdown: wikilinks, callouts, propertiesSteph Ango (MIT), credits

Skills reach every app. Claude Code and other skill-aware apps read the skills/ folder. Any MCP app gets the same text as prompts: getting-started, for example, is the prompt named getting-started. Third-party skills keep their own license files. See CREDITS.md.

Install

Knowledge needs Python 3.11 or newer. With uv you don't install anything ahead of time:

uvx knowledge-bundle-mcp --version

Or with pip:

pip install knowledge-bundle-mcp

Pinned install. For a fixed setup, pin the exact version. The plugin manifest pins it the same way:

uvx knowledge-bundle-mcp==0.2.1 --version

As a Claude Code plugin. One install gives you the MCP server and the skills. This needs the seayniclabs/plugins marketplace, which is published with the release:

/plugin marketplace add seayniclabs/plugins

/plugin install knowledge@seayniclabs

The plugin still needs your Open Notebook address in its settings. The plugin file is .claude-plugin/plugin.json.

First five minutes

  1. Set KNOWLEDGE_OPEN_NOTEBOOK_URL to your server's address (step 2 below shows where).
  2. Run the check. It prints ok or FIX for each item and exits 0 when everything is ready:
   knowledge-bundle-mcp --doctor
  1. Start your assistant and ask it to list your notebooks. It calls open_notebook_notebooks and shows you the names.
  2. Ask it to search a word you know is in one of your notes. It calls open_notebook_search.
  3. Ask it to save a note. It shows a preview first, then asks you to approve the save in your app.

Settings

Set these as environment variables in your MCP client's config, or put them in a config file (see below). Knowledge starts without any of them and tells you what's missing when you call a tool.

VariableModuleWhat it is
KNOWLEDGE_OPEN_NOTEBOOK_URLopen_notebookAddress of your Open Notebook server, e.g. https://notebook.example.com. No path.
KNOWLEDGE_OPEN_NOTEBOOK_PASSWORDopen_notebookOnly if your server has a password (OPEN_NOTEBOOK_PASSWORD on the server). Leave it unset otherwise.
KNOWLEDGE_OPEN_NOTEBOOK_REQUIRE_CONFIRMopen_notebooktrue by default: you approve each new note and link. false lets the assistant save them on its own. Local files always need your approval.
KNOWLEDGE_OPEN_NOTEBOOK_ALLOWED_NOTEBOOKSopen_notebookOptional. Comma-separated notebook names the assistant may save links and notes to without asking, e.g. Research,Inbox
KNOWLEDGE_APPROVAL_LOGanyOptional. Where the approval log is written. Default: ~/.local/state/knowledge/approvals.jsonl
KNOWLEDGE_ _ENABLEDanyfalse turns a module off, e.g. KNOWLEDGE_OPEN_NOTEBOOK_ENABLED=false

Config file (optional). Knowledge also reads ~/.config/knowledge/config.toml, or the file named by KNOWLEDGE_CONFIG. Environment variables win over the file.

[open_notebook]

url = "https://notebook.example.com" password = "change-me" require_confirm = true

Add it to your MCP client

Most clients use the same JSON shape. Put it where your client keeps MCP servers:

{

"mcpServers": { "knowledge": { "command": "uvx", "args": ["knowledge-bundle-mcp"], "env": { "KNOWLEDGE_OPEN_NOTEBOOK_URL": "https://notebook.example.com" } } } }

ClientWhere the config goes
Claude Desktopclaude_desktop_config.json (Settings → Developer → Edit Config)
Claude Codeclaude mcp add knowledge -- uvx knowledge-bundle-mcp, then add the env values, or a project .mcp.json
Cursor~/.cursor/mcp.json, or .cursor/mcp.json in a project
VS Code.vscode/mcp.json, using "servers" instead of "mcpServers"
Sonique, Hermes, OpenClaw, othersAny client that launches a stdio MCP server: command uvx, args ["knowledge-bundle-mcp"], plus the env values

Over HTTP. For clients that connect to a URL instead of launching a process:

knowledge-bundle-mcp --transport http --port 8765

It serves streamable HTTP at http://127.0.0.1:8765/mcp. It listens only on your own machine by default. Put authentication in front of it before exposing it anywhere else.

Try these

Paste any of these into your assistant once Knowledge passes --doctor:

  1. "List my notebooks and tell me which one changed most recently."
  2. "Search my notebooks for what I wrote about the Q3 budget, and cite each note."
  3. "Write a weekly review of the notes I changed this week, using the weekly-review skill."
  4. "Make an ADR for choosing SQLite over Postgres for the prototype, with the alternatives table filled in."
  5. "Save this link to my Research notebook: https://example.com/article. Show me the preview first."

Tools

ToolWhat it returns
knowledge_modulesWhich modules are on, which settings are missing, the skills, and the publisher. Call this first.
open_notebook_notebooksYour notebooks, most recently updated first, paged
open_notebook_searchMatching sources and notes. mode is text (keywords) or vector (meaning; needs an embedding model on the server). Optional notebook_id. Paged.
open_notebook_notesThe notes in one notebook, titles only, paged
open_notebook_note_getOne note's content, cut at max_chars
open_notebook_source_getOne source: title, topics, extracted text, notebooks, processing status
open_notebook_note_createSaves a note after you approve it. Without confirm=true it only returns a preview.
open_notebook_add_sourceAdds a web link, or a local file you name, as a source. Preview first; you approve it. Processed in the background.

Every tool returns structured data with a published schema, so an assistant can work with the results instead of parsing text. Errors always look like knowledge. . : Fix: .

Safety

  • Knowledge only calls the Open Notebook server you configure. It sends nothing anywhere else and keeps no data of its own.
  • open_notebook_note_create and open_notebook_add_source change your notebooks, so you approve each one. When the assistant asks to save, Knowledge asks you directly through your MCP client (MCP elicitation) and shows the notebook, the title and the full text or link. The assistant can't answer that question for you.
  • A local file is read only after you name it, and it is uploaded only after you approve its full path and size. Files named like credential stores (.env, .netrc, private keys, *.pem, *.key) and files in ~/.ssh, ~/.aws or ~/.gnupg are refused.
  • Some MCP clients can't ask you questions yet. In those, Knowledge refuses to write unless you've pre-approved the notebook with KNOWLEDGE_OPEN_NOTEBOOK_ALLOWED_NOTEBOOKS, or turned approval off with KNOWLEDGE_OPEN_NOTEBOOK_REQUIRE_CONFIRM=false. Local files are never pre-approved.
  • Before anything is written or sent, text that looks like a credential (API keys, tokens, private keys, passwords in URLs) is refused. The error names the kind of credential found, never the value.
  • Use an https:// address for your server, and give the password only to Knowledge, not to other tools.
