Semantic search and pattern discovery for Obsidian and markdown vaults.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

Common questions

Is Enzyme safe?

It passed 1 of 1 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

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 –, and the latest version (0.13.2) reached the registry 12 days ago.

Which apps can use it?

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

What can I use instead?

🧬 Enzyme

Enzyme compiles your notes and other knowledge sources into a local index that:

  1. Uses temporally grounded context sampling that captures the contextual use of tags and wikilinks, or natural accumulation in folders (i.e. pseudo-Zettelkasten)
  2. With this context, it "dreams" questions in the background (called catalysts) and embeds them. At query time, each question finds its nearest docs, so it avoid needing to "dream" full summaries. (see note)
  3. Keeps refreshing, but separates new doc ingestion (local, fast) from catalyst evolution (cheap, periodic)

The catalysts help orient the agent to the wiki. Enzyme saves up to 50% tokens vs. plain agentic search with grep.

*(Note: your system may already generate lots of memories in different buckets; Enzyme catalysts help thread them together)*

Get started

Open your Markdown notes folder with your agent and paste this prompt.

Set up Enzyme for the Markdown notes folder I have open. If you cannot identify it, ask me for its path.

Install Enzyme if needed using https://raw.githubusercontent.com/byenzyme/enzyme/main/install.sh, and install the instructions for this agent. Read and follow the installed enzyme-workspace-setup skill.

Use it to suggest settings from my notes and prepare search. Show me what you propose to include or exclude, and let me correct it before building the local search index.

Then answer one useful question using my notes, with links to the sources, and suggest a question I can ask next. Keep my existing notes in place and unchanged. Ask separately before any cleanup, model download, or recurring task.

After setup, keep working with your agent as usual. The new guidance tells your agent how to use Enzyme and when to refresh it.

Prefer to install it yourself first? Run this, then paste the same prompt:

curl -fsSL https://raw.githubusercontent.com/byenzyme/enzyme/main/install.sh | bash

cd /path/to/your/notes enzyme install claude # or: codex, hermes, openclaw

What it's for

Enzyme was built for knowledge bases that grow quickly:

  • Obsidian vaults that accumulate dated notes in a few folders
  • Meeting notes and AI-native, Markdown CRM setups
  • Agent memory written as Markdown

At setup time, it proposes a .enzyme program by reading your wiki and existing agent instructions, like:

profile relationships {

seek "what matters between people" notice ["meaningful exchanges", "shared interests", "unfinished conversations"] }

workspace "notes" { source markdown "notes" { path "~/notes" }

question budget 40 sample across time favor recent periods

learn questions from folder "people" including linked pages about relationships learn questions from folder "meetings" about operational learn questions from tags ["startup", "design"] about decisions learn questions from folder "inbox"

project questions into "~/notes/Readwise"

// Guidance compiled for your agent, not an enforced hook. when asked { "Use grep for names, titles, and exact phrases." retrieve passages through learned questions answer with sources } }

And you can give feedback to modify the program.

Enzyme helps most when a question spans many notes written over time: context for a decision on a project, or a broader theme arising from conversations with one person. It's designed to support knowledge captures that might be later be important, even if they don't serve a current task. Enzyme is focused on doing one thing well: giving agents the tools to make ideas compound. And it ships with a set of profiles designed around a personal knowledge base were refined over 2 years of personal use:

Reference

Setup without an agent
enzyme compile -v

Review the .enzyme settings file at the path printed by compile.

enzyme init --quiet enzyme doctor enzyme catalyze "a question about your notes"

compile proposes settings and saves them; init builds the local index from them; doctor reports what was indexed and any problems.

Other sources

For Apple Notes, a preset builds a named workspace program from your Notes database. Review the saved .enzyme program before running init:

enzyme --workspace apple-notes compile --preset apple-notes \

"$HOME/Library/Group Containers/group.com.apple.notes/NoteStore.sqlite" enzyme --workspace apple-notes init

For Are.na, use enzyme --workspace compile --preset arena and then enzyme --workspace init. Run refresh with the same --workspace name to pick up later changes (--collection is an accepted alias).

Retrieval commands

enzyme petri shows what Enzyme found worth asking about. In a terminal it renders a tree; piped, it emits JSON.

enzyme petri -n 2

An agent reads this map first, then searches. enzyme catalyze ranks notes by wording and meaning together, and each result carries the catalyst that best connects it to the query:

enzyme catalyze -n 3 "why we keep rewriting the auth layer" \

{

Message archives (_experimental_)

Enzyme indexes SQLite tables alongside Markdown — iMessage, WhatsApp, Mail, or any table of dated rows.

Declare a source sqlite inside a named workspace program, then run init and periodic refresh. The SQLite source setup skill shows the source declaration and source-scoped readings.

None of these is a special case. A handle_id column is repeated person values across dated rows, the same way [[links]] are repeated person values across dated notes. Both collapse to entity occurrences with effective dates, and nothing downstream knows which one it came from: the same profiles, budgets, and catalysts apply to a message thread and a folder of meeting notes.

A source names columns by the role they play rather than by the app they came from:

RoleMeans
idthe row's identity
whoparticipants; scalar, JSON array, or delimited
whenthe row's timestamp
whatthe text to read
wherethe container the row belongs to (optional)
weightnumeric significance per occurrence (optional)
API keys

Enzyme needs an API key only for catalyst generation and for Markdown enzyme compile's selection step. Source preset compilation does not call a model. By default enzyme init uses Enzyme's hosted bootstrap and ignores inherited OPENAI_* variables so it does not spend your personal key. Credential resolution is explicit key → configured local model → anonymous brokered free config, with no additional configuration.

The first configured vault on a machine initializes without login. Refresh, publishing, account credits, and additional vaults require enzyme login.

To bring your own OpenAI-compatible key, pass --llm env (alias --use-env-llm), which reads only OPENAI_API_KEY plus optional OPENAI_BASE_URL and OPENAI_MODEL. init and refresh also take --llm local (the installed local model; fails if none is installed), --llm hosted, and --llm none (index, embed, and selec
