rentready@0.8.2

CAUTION· not started

Publisher claims: "Enables agents to check whether an English rental property is ready for the landlord database, using a postcode and certificate dates to determine the region's registration window and deadline, flag gas safety, EICR and EPC records that expire or are missing, and report the fee, upload requirements and next actions. One tool, check_property, works offline apart from a postcode lookup and returns pass/warn/fail results." Observed in sandbox: no network, touches nothing outside the project, writes no memory.

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
GH_TOKENGITHUB_TOKENPOLAR_ACCESS_TOKENRESEND_API_KEYConfiguration, not credentials: GITHUB_OUTPUT, GITHUB_REPOSITORY, GITHUB_RUN_ID, GITHUB_SERVER_URL, GITHUB_STEP_SUMMARY, POLAR_PRODUCT_ID, POLAR_SANDBOX, RENTREADY_FROM, RENTREADY_GH_MONTHLY, RENTREADY_GH_ONE_TIME, RENTREADY_GH_ORG, RENTREADY_LIMIT, RENTREADY_PRODUCT_LIMITS, RENTREADY_STATE_DIR, RENTREADY_WARN_DAYS

What the honeypot saw
no credential files read · no network
What we could not test
server startup · the tool list · tool behavior

Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names gov.uk, campaign.gov.uk, legislation.gov.uk, parliament.uk, postcodes.io, polar.sh, resend.com, apple.com, statistics.gov.uk, sitemaps.org, hmrc.gov.uk, propertytribes.com as well as its own vendor. The guard injects GH_TOKEN, GITHUB_TOKEN, POLAR_ACCESS_TOKEN, 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.

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios; not started: dependency install failed; the server itself was not observed) on 2026-11-13 and scored it 78/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Direct script execution from GitHub raw URL; Hidden zero-width characters detected; Hidden zero-width characters detected. Summary: no network, touches nothing outside the project, writes no memory.
