What the Learning Commons connector does
The Learning Commons MCP server gives Claude, ChatGPT and any MCP agent authoritative US K-12 academic standards. Three read-only tools resolve a standard code into its official statement, break it into granular learning components, and trace prerequisite progressions. It reaches a public reference graph, never a student record, and the data is CC BY 4.0.

Limits
- Anthropic's documentation URL for this connector is dead. The directory nominates
docs.learningcommons.org/knowledge-graph/using-knowledge-graph/claude-connector, which returned 404 on 2026-08-23. The server and the documentation are both alive — the working page is.../agent-plugins, and the docs host serves a 2,287-wordllms.txtindex and a 69,210-wordllms-full.txt. A dead doc URL is not a dead connector, and this entry has been misclassified as one before. - The vendor calls the MCP server early access. Its own page states the functionality is actively evolving and that breaking changes may occur. Anthropic's partner tier describes the listing, not the server's stability.
- "All 50 states" applies to one tool of three. Standards lookup covers all 50 via CASE data. Math learning components cover 42 jurisdictions K-12. ELA learning components are K-2 only, across 13 jurisdictions — so a 5th-grade ELA standard has no components to return.
- Progressions are mathematics only. The tool is backed solely by the Student Achievement Partners Coherence Map for Common Core mathematics, K-12. The name
find_standards_progression_from_standarddoes not say so. - Newly added frameworks are not yet aligned. Learning Commons' v1.12.0 release notes (4 August 2026) state that standards frameworks added in that release are not yet aligned with learning components, and that all existing component-to-standard alignments still reference the older frameworks. Deprecated frameworks are marked
isCurrent=falserather than removed. - Two tools need a UUID you do not have yet. Both component and progression tools require a
caseIdentifierUUID, not a human-readable code, so a question about a standard code has to resolve the statement first. Chain the tools; do not expect either to work from a bare code. - Attribution is a licence condition. The data is CC BY 4.0. The
attributionStatementfield arrives with the response, but nothing forces it to survive into whatever the agent writes. - Not for high-stakes decisions. Learning Commons' terms state the resources are not intended for formal student evaluation, instructional placement or grading, and that claims of accuracy, safety, fairness or pedagogical effectiveness should not be made solely from these outputs.
- Rate limits are 2 requests per second, burst to 10, with HTTP 429 on breach. Those figures are published for the Knowledge Graph API; no separate MCP figure is documented.
- We could not read tool schemas or safety annotations. The endpoint returned 401 to an anonymous request, so no
readOnlyHintordestructiveHintis reported here. Parameter detail comes from the vendor's documented input table, not from the server. - A curriculum-alignment tier is gated. Learning Commons marks curriculum alignment as gated functionality requiring a support request, so parts of the graph are not reachable by default.
Frequently asked questions
Can the Learning Commons connector see student data?
No. All three tools take a standard code or a CASE UUID and return published reference data about that standard. Nothing in the surface accepts a student name, roster, score or submission, and no tool writes anywhere. Learning Commons publishes no student-data commitment for the connector because the connector never reaches a system that holds any.
Does the Learning Commons connector require an API key?
Not in Claude. Learning Commons states the connector is free and available to all Claude users, and its Claude setup steps ask only for a Claude account. The raw endpoint does require a key — an anonymous request returned HTTP 401 with a www-authenticate Key challenge on 2026-08-23 — so direct MCP clients need a Learning Commons Platform key.
Can the connector generate lesson plans or practice problems?
The model generates them; the connector only supplies the facts. All three tools read. Learning Commons' entire Knowledge Graph REST API is 31 operations and every one is a GET, with no POST, PUT, PATCH or DELETE anywhere. Anthropic records the permissions as Read. The word Generate in the listing describes Claude's output, not a tool.
Which states and subjects does the Learning Commons connector actually cover?
Standards lookup covers all 50 states; the other two tools cover much less. Math learning components span 42 jurisdictions across K-12, but ELA learning components are K-2 only across 13 jurisdictions. Progressions come solely from the Math Coherence Map, so an ELA prerequisite question has no data behind it.
Do you have to credit Learning Commons when you use the data?
Yes. Knowledge Graph data is licensed CC BY 4.0, which makes attribution a licence condition rather than a courtesy. Learning Commons documents that standards responses carry the source attribution the licence requires, and its API returns an attributionStatement field. Code is MIT; the progressions are CC0 from Student Achievement Partners.
Is the Learning Commons MCP server production-ready?
Learning Commons labels it early access. Its MCP server page carries a badge saying the functionality is actively evolving and that breaking changes may occur as it expands capabilities and improves accuracy. The connector itself is listed by Anthropic as a partner connector, but the vendor's own stability warning applies to the server behind it.
Are there rate limits on the Learning Commons Knowledge Graph?
Yes, on the underlying API. Learning Commons documents 2 requests per second with burst capacity up to 10, HTTP 429 on breach, and advises exponential backoff. It invites teams to email support to request an adjustment. The published figures describe the Knowledge Graph API; the vendor states no separate MCP limit.
Can this connector be used for grading or student placement?
No, and Learning Commons forbids it. Its terms of use state the resources are provided for exploratory and research use and are not intended for high-stakes educational decisions such as formal student evaluation, instructional placement, or grading. It also states human judgement is expected when interpreting results.
