Nordic Claude Plugin
A Claude Code plugin for Nordic Semiconductor AI-assisted development. It wires up
two hosted MCP servers and teaches Claude how to use them well:
- Nordic MCP — nRF Connect SDK (NCS) documentation, environment setup, build,
program, and debug workflows. Endpoint
https://aidev.nordicsemi.com/mcp,
authenticated with your myNordic account.
- nRF Cloud MCP — read-only fleet telemetry (issues, traces, device metrics,
software-version health), hosted by Memfault. Endpoint
https://app.memfault.com/mcp,
authenticated with your nRF Cloud account.
Both are hosted HTTP servers — nothing runs locally and no npm package is installed.
What's inside
| Type | Name | Purpose |
|---|
| MCP server | nordic-mcp | NCS docs / setup / build / debug via myNordic OAuth |
| MCP server | nrfcloud | Read-only nRF Cloud fleet telemetry via OAuth |
| Skill | using-nordic-mcp | Nordic's prompting best practices (context, sources, guardrails, setup-vs-dev) |
| Skill | using-nrf-cloud-mcp | The 12 read-only tools, limits, and example prompts |
| Command | /nordic-setup-ncs | Start the NCS environment setup workflow |
| Command | /nordic-build-debug | Build / program / debug for a board target |
| Command | /nordic-search-docs | Look up Nordic facts via nordicsemi_search_sources |
| Command | /nordic-migrate | Migrate an app to another NCS version |
| Command | /nrfcloud-fleet | Query nRF Cloud fleet telemetry (read-only) |
Prerequisites
- Claude Code — a recent version with HTTP MCP and OAuth support.
- A myNordic account — required for Nordic MCP. Create one at
https://mynordic.nordicsemi.com/.
- An nRF Cloud account — required for nRF Cloud MCP. Create a free account if you
do not have one.
Install
Add this repo as a marketplace, then install the plugin:
/plugin marketplace add C:\Users\Wells\nordic-claude-plugin
/plugin install nordic@nordic-claude-plugin
Replace the path with this repo's location, or use its git URL once published:
/plugin marketplace add https://github.com/<your-account>/nordic-claude-plugin
/plugin install nordic@nordic-claude-plugin
First-run authentication
Both servers use OAuth. After installing:
- Run
/mcp in a Claude Code session.
- Select
nordic-mcp -> Authenticate -> sign in with myNordic in the browser.
- Select
nrfcloud -> Authenticate -> sign in with your nRF Cloud account, then
choose the organization and project to authorize.
Tokens refresh automatically. If a server stops working, re-authenticate from /mcp.
nRF Cloud: one server per project
nRF Cloud tokens are scoped to a single organization + project. To work with more than
one project, edit plugins/nordic/.mcp.json and add another entry with a distinct name
pointing at the same URL:
{
"mcpServers": {
"nordic-mcp": { "type": "http", "url": "https://aidev.nordicsemi.com/mcp" },
"nrfcloud": { "type": "http", "url": "https://app.memfault.com/mcp" },
"nrfcloud-staging": { "type": "http", "url": "https://app.memfault.com/mcp" }
}
}
Authorize each entry separately and name the project in your prompts.
Usage
Once authenticated, just describe your task — the bundled skills guide Claude
automatically. Examples:
- "Use Nordic MCP and install the nRF Connect SDK v3.3.0 and prepare a freestanding app
for the nRF54L15 DK. Pause before programming the DK."
- "Build and debug my app for nrf5340dk/nrf5340/cpuapp. Ask first if anything is unclear."
- "What are the top 5 open issues in my-project-prod by trace count?"
Or use the slash commands listed above.
Tips
- Use separate chats for environment setup vs. development work.
- Always give Claude the NCS version, full board target, and project path.
- For facts that change between SDK versions, ask Claude to verify against Nordic
sources rather than general knowledge.
- Confirm the target device before any flash or erase.
Security & safety
- nRF Cloud MCP is strictly read-only — it cannot modify your fleet.
- Nordic MCP can drive build / flash / erase actions. The bundled skills and commands
ask for explicit confirmation before touching hardware or project files. If your
client supports explicit tool confirmation, enable it for extra safety.
