aliasflare@0.2.0
VERIFIEDPublisher claims: "Self-hosted email aliases on Cloudflare Workers (free tier). Agents can create/list/delete aliases, read recent messages and fetch verification codes." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
Coverage
Server started and answered tools/list.- Tested
- MCP initialize and tools/list · every tool description, for hidden instructions · every file read, file written and host contacted by what ran
- Not tested
- what the tools do when called with real credentials
Before you give it your token
- It will ask for
ADMIN_TOKENALIASFLARE_TOKENBREVO_API_KEYRESEND_API_KEYConfiguration, not credentials: ALIASFLARE_URL, AUTO_CREATE, BANNER, BLOCK_TRACKERS, CODE_IN_SUBJECT, DESTINATION, DOMAIN, EMAIL, FORWARD_MODE- Where it talks to
- no vendor host named in the codeAlso workers.dev, resend.com, brevo.com — 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
- what the tools do when called with real credentials
Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names workers.dev, resend.com, brevo.com as well as its own vendor. The guard injects ADMIN_TOKEN, ALIASFLARE_TOKEN, BREVO_API_KEY, RESEND_API_KEY only into requests to the host you bind (and its subdomains) and refuses the rest.
Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.
Is [email protected] safe to install?
KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios) on 2026-11-11 and scored it 87/100 (Verified). It did what it claims and nothing else we could detect: no undeclared network egress, no credential reads, no persistent instruction writes. Summary: no network, touches nothing outside the project, writes no memory.

Tokens estimated at four characters each. The tool list is re-read by the agent on every turn, so it is the number to compare between servers that do the same job: ranked across the index.
