NGSS-MCP
Search and retrieve NGSS standards by code, domain, or topic. Explore three-dimensional components (SEPs, DCIs, and CCCs) and discover related standards by shared practices, concepts, or core ideas. Plan cohesive curriculum units with suggestions for compatible standards.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
get_standardRetrieve a specific NGSS standard by its code identifier (e.g., MS-PS1-1, MS-LS2-3, MS-ESS3-1)
search_by_domainFind all NGSS standards in a specific science domain (Physical Science, Life Science, or Earth and Space Science)
get_3d_componentsExtract the three-dimensional learning components (SEP: Science and Engineering Practices, DCI: Disciplinary Core Ideas, CCC: Crosscutting Concepts) for a specific standard (e.g., MS-PS1-1, MS-LS2-3, MS-ESS3-1)
search_standardsPerform full-text search across all NGSS standard content including performance expectations, topics, and keywords (e.g., "energy transfer", "ecosystems", "chemical reactions", "climate change")
search_by_practiceFind all NGSS standards using a specific Science and Engineering Practice (SEP). Examples: "Developing and Using Models", "Analyzing and Interpreting Data", "Planning and Carrying Out Investigations"
search_by_crosscutting_conceptFind all NGSS standards using a specific Crosscutting Concept (CCC). Examples: "Patterns", "Cause and Effect", "Systems and System Models", "Energy and Matter"
search_by_disciplinary_core_ideaFind all NGSS standards using a specific Disciplinary Core Idea (DCI). Examples: "Definitions of Energy", "Interdependent Relationships in Ecosystems", "Weather and Climate"
get_unit_suggestionsRecommend compatible NGSS standards for curriculum unit planning based on 3D framework overlap (domain, SEP, DCI, CCC). Example: Given anchor "MS-PS3-1" (energy), suggest 2-7 compatible standards that share similar practices, concepts, or disciplinary ideas for a cohesive unit
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
lodash vulnerable to Code Injection via `_.template` imports key names
lodash vulnerable to Prototype Pollution via array path bypass in `_.unset` and `_.omit`
Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
16/16 tools missing one or more hints — get_standard (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_by_domain (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_3d_components (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +13 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Shell command execution
3 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 4 high severity in production deps — @modelcontextprotocol/sdk@1.20.0 (high), @modelcontextprotocol/sdk@1.20.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
