Overview

Description from the maker (original English)

Path-scoped project memories, rules and skills for coding agents, on your machine or Pathrule Cloud.

PopNx MCP’s three pillars

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

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

You need

  • Runs in the cloudNothing to install; it connects over the internet
  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Works in Claude on the web, desktop and mobile:

  1. Open Settings → Connectors
  2. Press Add custom connector
  3. Paste the address below and press Add
  4. If it asks you to sign in, sign in with the maker

Or run it on your computer

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

Common questions

Is Pathrule 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?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.6) reached the registry 18 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, Recta

Your AI forgets. Pathrule remembers.

The open-source knowledge layer for coding agents. Pathrule keeps what your project has learned as memories, rules and skills scoped to paths in your code, and gives Claude Code, Codex, Cursor, GitHub Copilot and Windsurf only what the task in front of them needs, before they act.

PathruleBench, 2,000 items: 55% lower cost a chain · 2.7× fewer input tokens · 97% of memory probes passed · the numbers

Website · Docs · Quickstart · Benchmarks · Smarter over time · Changelog

Same request, same agent. On the right, Pathrule's hook hands over the three notes filed for apps/web/dashboard before the agent writes a line.

Works with Claude Code · Codex · Cursor · GitHub Copilot · Windsurf · any MCP client

Quickstart

Node.js 22.14.0 or newer, on macOS, Linux or Windows.

npm i -g @pathrule/cli

pathrule setup --local # no account: knowledge stays on this machine pathrule doctor # see what each agent receives

Restart your agent. From the next session on, it gets the notes for the path it is about to touch, and writes new ones as it works.

Explain it once

Coding agents start every session blank. So the same correction comes back, day after day, agent after agent:

DayAgentWhat you typed
MonClaude Code“use our api client, not fetch”1st
TueClaude Code“again: api client, not fetch”2nd
WedCodex“we use the api client.”3rd
ThuCursor“I told you yesterday. api client.”4th
FriClaude Code“API CLIENT. NOT FETCH.”5th

Five sessions, three agents, nothing remembered. With Pathrule you say it once:

  1. You fix it once, the way you normally would.
  2. Pathrule files it next to the code it is about: a memory on features/, not a line in a file every session has to read.
  3. Every agent knows from the next session on, whichever one you open.

Only what matters

A workspace collects hundreds of notes. An agent editing features/orders needs four of them.

Knowledge is matched by path, scope and relevance, then fit to a per-prompt budget. Enforced rules are never cut for space. Whatever does not fit is listed by title, so the agent can ask for it. When a prompt names a function or a type, the hook also points the agent to the file and line where it is defined (JS/TS, Python, Go).

Three kinds of knowledge
KindWhat it holdsExample on features/
MemoryDecisions, gotchas and incidents, in short markdown.“Use the api client. It handles auth and retries.”
RuleConstraints the agent must follow, ranked above advice.“Data loading goes through React Query.”
SkillReusable procedures and checklists an agent can run.“Run the checks before calling it done.”
Three ways in
ChannelWhen it reaches the agentCost
Path-scoped rule filesClaude Code reads Pathrule's own .claude/rules/pathrule/ at session start, each file scoped to its paths. Your CLAUDE.md and AGENTS.md are left as they are.Cached by the client.
HooksBefore the agent acts: on session start, on each prompt and on file tools. Only new or changed context is sent again.Budgeted per prompt.
MCP get_contextWhen the agent asks, at the depth the request needs.Every MCP client has it.

Why not just CLAUDE.md?

A CLAUDE.md file is read whole on every step, so every note your team adds makes every session cost more. Pathrule sends each prompt only what the path and the task need. PathruleBench measured the difference with the same agent, the same prompts and the same hidden checks, from 500 to 2,000 items of team knowledge.

At 2,000 items of team knowledgeCLAUDE.mdPathrule
Cost a chain of 8 sessions$3.89–$4.21$1.76–$1.89
Input tokens a chain11.8–12.5 M4.3–4.7 M
Memory probes passed89%97%
Chains that passed every memory probe0 of 95 of 9
A habit said once, followed later78%97%
What a failing command taught, kept33%78%
The work each prompt asked for100%100%

From 500 to 2,000 items, a chain with CLAUDE.md costs 89–98% more. With Pathrule it moves between −1% and +10%. Your knowledge base can grow; the bill does not.

Claude Code with claude-sonnet-5-5 in Python, Go and TypeScript; nine chains an arm at 2,000 items (three per language); executable tests decide every pass, no model judges. The Pathrule arm is this repository's open-source CLI in local mode: no Cloud, no model.

[Every condition, chain and check, and how to run it yourself → pathrule/benchmark](https://github.com/pathrule/benchmark)

Smarter the longer you use it.

Day one needs no account, no network and no model. Everything after builds on what you and your agents already did in this repository.

WhenWhat Pathrule doesWhere it runs

| Day 0 Foundation | Hooks and the local MCP server are wired into your agents. What you write is delivered per path, within a budget, through the hooks and Claude Code's path-scoped rules; your own CLAUDE.md and AGENTS.md are left as they are. | Open source, this machine | | Week 1 Memory | A decision you state in a prompt (“from now on…”, “we decided…”) is saved in your own words. A lesson a failing command taught is saved once. Each note is filed next to the code it is about, and only new or changed context is sent again. | Open source, this machine | | Month 1 Your habits | A preference you state lives in a local file of your own. Said once in passing, it waits; said again in another session, it reaches every agent. One you call lasting is in force at once. A project rule always wins over a personal one. | Open source, this machine | | Month 3 At scale | Thousands of notes, and a session stays the same size: the root rules file stays around 6k characters and the rest arrives per prompt. A sentence that says where code lives is marked (as of writing), so when a teammate moves the file the agent follows the code. When an edit writes a value a newer decision replaced, the hook quotes the decision at that edit. | Open source, this machine | | When you choose Team | The same knowledge on every machine and for every member. For a Cloud workspace, a model also reads the prompts Pathrule's phrase rules found nothing in and keeps the sentence you meant to last, still in your words. It is paid from AI Credits. | Pathrule Cloud, opt-in |

No model runs on your machine. Everything before Team is the open-source CLI, the same path the benchmark above measured.

Switch agents. Keep the knowledge.
