Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
E2B
Giving Claude ability to run code with E2B via MCP (Model Context Protocol).
Embedded / IoT Mentor
Embedded/IoT mentor: picks the board and toolchain, estimates cost and battery life.
How to run each
E2B As a local MCP server: Docker image
claude mcp add --env "E2B_API_KEY=<YOUR_E2B_API_KEY>" --transport stdio e2b -- docker run -i --rm -e E2B_API_KEY mcp/e2bRequires: E2B_API_KEY (secret)
Embedded / IoT Mentor
No data for an automatic command: what its marketplaces declare does not say unambiguously how to connect it.
Commands built only from what the marketplaces declare; the full set for every client is on each card.
Tools each declares
The marketplaces of Embedded / IoT Mentor publish no list of tools, so we do not compare tools.
Settings each asks for
Only E2B asks for
E2B_API_KEY (secret)
Only Embedded / IoT Mentor asks for
HOSTPORT
Settings as each marketplace publishes them. Asking for fewer is not better in itself.
