Overview

Description from the maker (original English)

158,000+ K-12 education standards across 300 curriculum systems, cross-referenced via NLP.

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.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Other
  • You need to fill in: DB_PATH

Install

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

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: DB_PATH

You need

  • PyPIPython’s uv installed (for the uvx command)

Which app do you use?

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

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

{
  "mcpServers": {
    "standardgraph": {
      "command": "uvx",
      "args": [
        "standardgraph"
      ],
      "env": {
        "DB_PATH": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add standardgraph --env DB_PATH=your-value -- uvx standardgraph

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "standardgraph": {
      "command": "uvx",
      "args": [
        "standardgraph"
      ],
      "env": {
        "DB_PATH": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "standardgraph": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "standardgraph"
      ],
      "env": {
        "DB_PATH": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • DB_PATH required env
    Path to the common_core.db SQLite database (downloaded by install.sh to ~/.standardgraph/common_core.db)

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is StandardGraph 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?

You need to fill in: DB_PATH

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 (1.2.3) reached the registry 4 months 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?

StandardGraph

The alignment layer for the global curriculum. Map any standard to its equivalent in another country or exam board — cross-border alignment no single-country tool provides.

175,046 standards across 307 curriculum systems in 50+ countries, cross-walked into a single graph and accessible via Claude.

🎯 Every crosswalk in the graph is now quality-scored. All 173,485 crosswalks carry a 1–5 LLM quality score. Weak matches (low score, or embedding similarity below 0.75) are suppressed by default, which raised measured precision on a blind-labelled test set from 79% to 91% (partly or fully correct). Results are ranked by alignment quality, so what you get back is the strongest match first.

⚡ Try it in 30 seconds — no install. In Claude, go to Settings → Connectors → Add custom connector and paste https://standardgraph.walkmakewalk.com/mcp. No download, no token. (full instructions ↓)

Covers Mathematics, Science, ELA, Social Studies, Computer Science, Arts, and World Languages — US national and state standards plus major international curricula. Ask Claude to look up any standard, trace a concept across grade levels, or find the equivalent in another country's curriculum.

Who this is for:

  • EdTech engineers & curriculum teams — mapping content to standards, building alignment features, or auditing coverage across states and countries without hand-building a crosswalk.
  • Teachers and curriculum specialists moving between systems — "I taught IB in Singapore, now I'm teaching CCSS in Texas — what's actually different at this grade level?"

If you're doing either of those by hand today, this replaces the spreadsheet.


Install

Option A — Hosted connector (no install) ⚡

The fastest way to try it — no download, no terminal. In Claude, go to Settings → Connectors → Add custom connector, name it StandardGraph, and paste this URL:

https://standardgraph.walkmakewalk.com/mcp

Connect, and StandardGraph's tools are available in any conversation. Works in Claude on web, desktop, and mobile. *(Custom connectors require a paid Claude plan. The hosted server runs on modest hardware — ideal for trying it out and light use; for heavy or offline use, install locally below.)*

Option B — Local install (offline / self-host)

Runs entirely on your machine against a local copy of the database. Requires Claude Desktop. Open Terminal and run:

curl -fsSL https://raw.githubusercontent.com/swoopeagle/standardgraph/main/install.sh | bash

Then quit and reopen Claude Desktop. Look for the 🔨 icon in a new conversation.

The installer handles everything: downloads the pre-built database (~850 MB), installs dependencies, and patches your Claude config automatically.

Optional: better semantic search

Install Ollama and pull the embedding model for richer concept matching:

brew install ollama

ollama pull nomic-embed-text

Without Ollama, StandardGraph falls back to keyword search — still useful, but semantic search finds conceptually related standards even when the exact words don't match. See docs/install.md for full setup details.

Try it:

Using with Claude

StandardGraph works out of the box once installed, but pasting the following into your Claude Project instructions (Settings → Projects → [your project] → Instructions) gives Claude better guidance on how to use the tools and how to interpret results:

Copy this into your Claude Project instructions

You are a K-12 curriculum expert with access to StandardGraph — a database of 175,000+ standards across 307 curriculum systems in 50+ countries, covering Math, Science, ELA, Social Studies, Computer Science, Arts, and World Languages.

When the user asks about standards, use these tools:

  • search_standards — when they describe a concept and want matching standards
  • lookup_standard — when they cite a specific standard ID (e.g. CCSS.MATH.6.RP.A.3)
  • get_progression — when they ask how a topic develops across grade levels
  • get_learning_path — when they want an ordered study plan of prerequisites for a target standard
  • map_standard — when they want the equivalent standard in another curriculum or country
  • list_systems — when they want to know which systems are available

Reading crosswalk confidence scores:

  • ≥ 0.90: Strong match — same concept, aligned grade level
  • 0.85–0.89: Good match — same concept, may differ by ±1 grade
  • 0.75–0.84: Plausible — related concept, scope or grade may differ; flag as "worth verifying"
  • < 0.75: Weak — treat as a starting point only, not a definitive equivalent

When grade_delta ≠ 0, note which curriculum introduces the concept earlier or later. A negative delta means the source curriculum teaches it at a lower grade than the target.

Tool chaining patterns:

  • Compare two systems on a topic: search_standards in system A, then system B with the same query
  • Deep dive on a standard: lookup_standard → follow prerequisites/successors → map_standard to compare
  • Cross-curriculum progression: get_progression in CCSS, then map key grade stages to another system

Known limitations — read before using map_standard or list_systems:

  • Crosswalks are stored one-directional (non-hub → hub, e.g. sg-moe → ccss), not mirrored. Mapping *from* a hub to a non-hub system (e.g. "what's the Singapore equivalent of this CCSS standard?") often falls through to a weaker semantic fallback even when a strong reverse mapping exists. Always call map_standard with the non-hub/state/international/AP system as from_system and the subject's hub (ccss, ngss, ccss-ela, c3, csta) as to_system — flip the user's framing if needed, then present the result in the direction the user actually asked about. Mapping between two non-hub systems directly (e.g. Singapore → UK) is also less reliable than routing through the hub.
  • list_systems' region filter has metadata gaps — some international systems are tagged inconsistently and a region like "Sub-Saharan Africa" may under-match. Prefer filtering by subject alone, or reference systems by their code directly, rather than relying on region to enumerate everything available.

Always note:

Crosswalk mappings are NLP-generated (cosine similarity), not human-verified. Present them as "closest available match" rather than "equivalent." For high-stakes decisions — student placement, curriculum adoption, teacher credentialing — recommend expert review for any mapping below 0.85 confidence.

StandardGraph also ships three MCP prompt templates that Claude can invoke directly. In a conversation with StandardGraph connected, try:

  • /curriculum_assistant — sets Claude up as a curriculum specialist for the session
  • /compare — side-by-side comparison of two curriculum systems on a topic
  • /find_equivalent — maps a specific standard ID into another curriculum
