fwrd-sms-mcp@1.0.0
VERIFIED· install onlyPublisher claims: "Enables an AI agent to wait for and retrieve SMS verification codes forwarded from your iPhone, returning each code once, and to list recent texts for login links or non-numeric messages. It runs in your own Cloudflare account and deletes stored texts after 15 minutes." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
Coverage
Nothing executable in the bundle ran; the trace covers the install step only.- Tested
- every file read, file written and host contacted by what ran
- Not tested
- use of the skill by an agent
What this means for the label: Verified 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
FWRD_TOKENMCP_TOKENMIN_SECRET_LENGTHConfiguration, not credentials: ALLOWED_ORIGINS, CLIENT_CAPABILITIES_KEY, FWRD_MCP_PORT, INBOX, KEEP_SECONDS, PROTOCOL_VERSION_KEY- Where it talks to
- no vendor host named in the code
- What the honeypot saw
- no credential files read · no network
- What we could not test
- use of the skill by an agent
Connect it with a scoped credential, under the guard. It asks for FWRD_TOKEN, MCP_TOKEN, MIN_SECRET_LENGTH and talks to its vendor. Give the credential to the guard, not the server: the value never enters the server's environment and only travels to the host you bind. What the tools do with a real credential was not observed.
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 (1 scenario; nothing executable in the bundle ran; the trace covers the install step only) on 2026-11-14 and scored it 88/100 (Verified). In what ran, nothing we could detect went wrong: no undeclared network egress, no credential reads, no persistent instruction writes. What it does with a real credential was not observed; the static findings and the publisher carry the rest of the score. Summary: no network, touches nothing outside the project, writes no memory.

Tokens estimated at four characters each. Skills load their instruction text when triggered; the figure is what that costs.
