meshtastic-mcp@0.1.0

CAUTION· not started

Publisher claims: "MCP server + agent skills for AI tooling to discover, drive, observe, and test Meshtastic devices and apps: device discovery, serial/TCP transport, admin, recorder/observability, PlatformIO build/flash (optional), and hardware-free Android-emulator e2e." Observed in sandbox: no network, touches nothing outside the project, writes no memory.

Coverage

Not started: dependency install failed; the server itself was not observed.
Tested
the dependency install step · every file read, file written and host contacted by what ran
Not tested
server startup · the tool list · tool behavior

What this means for the label: Caution here covers what ran. The server's tools were not exercised with a real credential, so nothing about their behavior is asserted; the credential summary below says what to do with that.

Before you give it your token

It will ask for
no credential variables read in the code
Where it talks to
meshtastic.org (its own)Also nodejs.org, agentskills.io, platformio.org, google.com, githubusercontent.com, llama.app — not the publisher's domain; check what for before connecting.
What the honeypot saw
no credential files read · no network
What we could not test
server startup · the tool list · tool behavior

Connect it under the guard. Not started: dependency install failed; the server itself was not observed. The code names no credential variable and talks to meshtastic.org, its own; the guard pins the network to what the honeypot saw and logs every call.

$vet-skills run --net declared -- uvx meshtastic-mcp

Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios; not started: dependency install failed; the server itself was not observed) on 2026-11-11 and scored it 68/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Access to sensitive file paths; Pipe-to-shell pattern; Pipe-to-shell pattern. Summary: no network, touches nothing outside the project, writes no memory.
