StandardGraph indexes 175,738 education standards across 310 curriculum systems in 50+ countries β CCSS, all 50 US states, Canada, the UK, Australia, Singapore, Japan, India, IB, Cambridge, and more β across seven subjects, semantically cross-referenced and accessible via Claude MCP.
Every crosswalk in the graph is now quality-scored. All 208,442 crosswalks carry a 1β5 LLM quality score (100% coverage) β direct country-to-country edges and every hub mapping across all seven subjects. Weak matches are auto-suppressed, so results come back ranked by real alignment quality.
Find standards by concept, not just keyword. Every standard is embedded with nomic-embed-text and stored as a 768-dim vector for cosine similarity search.
Each subject maps to its hub (CCSS for math, NGSS for science, and so on) via NLP similarity, with confidence scores, grade-delta flags, and 1β5 LLM quality scores. Sibling curricula also get direct country-to-country edges.
Built as a FastMCP server. Plug it into Claude Desktop and ask questions in plain English β no API keys, no boilerplate.
Standards from 50+ countries and regions across seven subjects, cross-referenced to subject hubs. A sample of the 310 systems is shown below.
CCSS hub + all 50 states + DC. Sourced from commonstandardsproject.com.
Six provincial curricula.
England National Curriculum, AQA GCSE, and Scotland's Curriculum for Excellence.
Australian Curriculum (ACARA) and Victorian Curriculum.
Cambridge International Education (Primary β IGCSE) and IB (MYP + Diploma).
Planned expansions beyond mathematics.
Four tools exposed to Claude. Ask questions in plain English β the right tool is called automatically.
lookup_standard
Fetch the full text, domain, cluster, prerequisites, and successors for a known standard ID.
e.g. "What does CCSS 6.RP.A.3 say?" Β· "Show me TX.MATH.5.3.K"
search_standards
Semantic search across any system by concept. Returns ranked matches with relevance scores.
e.g. "Find grade 5 Texas standards about fractions" Β· "Cambridge standards on quadratic equations"
get_progression
Trace how a concept develops from K through HS in any curriculum system.
e.g. "How does place value build up through CCSS?" Β· "IB progression for probability"
map_standard
Find the closest equivalent to a standard in another curriculum. Returns confidence score and grade alignment.
e.g. "What's the CCSS equivalent of this Ontario standard?" Β· "Map TX.MATH.5.3.K to CCSS"
Two steps to get StandardGraph working in Claude Desktop.
# Requires Python 3.11+ and uv
git clone https://github.com/swoopeagle/standardgraph.git
cd intl-math-standards-mcp
uv sync
Edit ~/Library/Application Support/Claude/claude_desktop_config.json:
{
"mcpServers": {
"intl-math-standards": {
"command": "/path/to/intl-math-standards-mcp/.venv/bin/python",
"args": ["-m", "common_core.server"]
}
}
}
Restart Claude Desktop. The hammer icon will show intl-math-standards as a connected server.
