Summary

Remote MCP server for Memfault (Nordic Semiconductor) exposing 18 read-only tools over device fleet telemetry — device vitals, timeseries, crash issues, traces, metrics and software versions.

Features

  • 18 read-only tools over device fleet telemetry
  • Device vitals, attributes, timeseries and reboot history
  • Crash issue search plus trace retrieval
  • Metrics and per-software-version vitals
  • OAuth 2.0 with PKCE, scoped to one org and project
  • Per-plan rate limits from 30 to 300 calls per hour

Installation

Set up this MCP server in your favorite AI agent — copy a ready-made configuration below.

Any MCP-compatible agent

Most agents (Claude, Cursor, Windsurf, VS Code, and more) read a standard mcpServers configuration.

  1. Open your agent's MCP configuration file.
  2. Merge the snippet below into it.
  3. Restart the agent — the "Memfault MCP Server" tools will be available.

Description

Memfault MCP Server is the hosted Model Context Protocol endpoint for Memfault, the embedded device observability platform now part of Nordic Semiconductor. It puts a connected-device fleet's telemetry behind an AI client, so questions like "which firmware version is rebooting most this week" can be answered without hand-building a dashboard.

Read-only by design. All 18 tools are reads, and the default OAuth scopes (device:read, issue:read, chart:read, deployment:read, alert:read, project:read, org:read, me:read) grant nothing else. An agent can investigate a fleet but cannot deploy to it.

Tool groups

  • Devices — device_get, device_getAttributes, device_getTimeseries, device_getVitals, device_search, device_listReboots
  • Issues and traces — issues_list, issue_search, issue_get, issue_getTraces, trace_get
  • Metrics — metrics_list, metrics_listReportTypes
  • Software versions — softwareVersions_list, softwareVersion_getVitals
  • Processing logs — processingLog_listEventTypes, processingLog_search
  • Projects — projects_list

Access and limits

Authentication is OAuth 2.0 with PKCE; a token is scoped to one organisation and project chosen at authorisation time and expires after an hour, with refresh support. Call limits apply per organisation across every authenticated client: 30/hour and 100/day on Developer, 100/hour and 500/day on Pro, and 300/hour and 5,000/day on Enterprise. Clients without native remote MCP support connect through mcp-remote.
