Enables rent negotiation analysis for Zillow rental listings: accepts a Zillow listing link or ID and returns comparable nearby listings, listing history and price-cut signals, an offer/settling estimate, a message to send, and lease renewal pricing guidance. Also supports scoring a rental from manually entered rent/ZIP/bed/bath/sqft details when a listing lookup is unavailable.
This server does not currently have a deployable release on Glama. Follow the repository's setup instructions to install and configure it for your MCP client, including any required credentials and local dependencies.
Rent negotiation numbers for any Zillow rental: what similar places nearby ask, how long it has really been listed (Zillow's counter restarts on a relist), whether it has been cut, what an empty month costs the landlord, an offer, a likely settling point, and a message to send. Also prices a lease renewal increase.

As a plugin (adds the MCP server and a skill that knows when to use it):
claude plugin marketplace add peterskotte123/lowball-plugin
claude plugin install lowball@lowballOr just the MCP server:
claude mcp add lowball -- npx -y @lowball/mcpThen paste a Zillow rental link and ask what to offer.
Run npx -y @lowball/mcp as a stdio server. Three tools:
tool | takes | gives |
| a Zillow listing link or id | the numbers, the reasons, the closest comparable listings, and a message |
| rent and ZIP, plus beds, baths, sqft, days, type | the same, for a rental you describe yourself |
| current rent, proposed rent, ZIP, plus beds, years, free months | a counter, the landlord's cost if you leave, and the reasons |
Lowball is trained on San Diego County rental listings and tracks them nightly (cuts, relists, exits). There it gives one number with a confidence level. Anywhere else it builds the estimate from like-for-like listings it has seen within a few miles and says so with a wider range. Monthly figures are published at lowball.rent/rent-report.
Each call is one HTTPS request to api.lowball.rent carrying only the Zillow id or the numbers you typed. No name,
email or account. Listing lookups are capped per day across all users; when the cap is hit, score_rental with the
numbers typed in still works. Privacy: lowball.rent/privacy.
Zero dependencies, Node 18+. node cli/lowball.js runs the MCP server on stdio; node cli/lowball.js check <link>
runs the terminal check. Set LOWBALL_API to point at a local API.
