AddressIntel MCP server
by RantumBits · official
Look up SF Peninsula building permits, SB 9 lot-split eligibility and ADU or redevelopment leads right in your chat.
This is a helper that connects your AI assistant to AddressIntel, a service that holds building permit and parcel data for the San Francisco Peninsula. It is handy if you work in real estate, development or planning and you want quick answers about what has been permitted or what a lot could support. Everything it does is read-only, so it only looks things up and never changes anything.
What is an MCP server? The 30-second version
On its own, your AI can only chat with you using what it already knows. An MCP server is a small helper program that gives your AI a new skill or a connection to an outside service. This one connects your AI to AddressIntel, so when you ask a question about permits or a parcel, the AI can go and look it up there for you. You just ask in normal words, and the helper does the fetching.
What this MCP server does
You ask your AI something like which demolition permits were issued in Menlo Park this year. The AI passes your question to this helper, which sends it to the AddressIntel service. AddressIntel searches its permit and parcel records and sends the results back. The helper hands those results to your AI, which turns them into a clear answer in your chat. You never have to open a website or fill in a search form yourself.

- Get full scores and comparable sales for one property
Try asking your AI
- “What demolition permits were issued in Menlo Park this year?”
- “Which Palo Alto listings are SB 9 eligible?”
- “Show me parcels in Redwood City with room for an ADU”
- “Which listings in Burlingame look like good teardown candidates?”
What it gives back to you
You get answers in plain text in your chat, often as a short list of permits, listings or parcels with the key details. Some tools give scores and comparable sales for a single property. The AI may summarise the results or lay them out as a table, depending on what you ask. Nothing is changed on the AddressIntel side, since every lookup is read-only.
Before you start
What you need
- An AddressIntel API key (a kind of password for apps; you can get a free one at addressintel.co/developers, and it is emailed to you)
- Node.js installed on your computer, since the helper runs through npx
- An AI app that supports MCP servers, such as Claude Desktop or Claude Code
Good to know
It only reads data, so it cannot change or delete anything, but it needs your AddressIntel key and the free tier has limits on how many requests and rows you get.
Install it with your AI
Add AddressIntel MCP server to your AI, no technical skills needed
You don't install anything by hand. You copy one prompt, paste it into an AI that can work on your computer, and it checks, installs and connects the server for you, asking you when it needs something.
Sign in to get the install prompt
Members get a ready-made prompt that lets the Claude desktop app check AddressIntel MCP server, install it and connect it for them, step by step. You don't need any technical skills: you copy, paste and answer a few questions. Your connected AI can also find and install any of the 4,066 MCP servers here for you.
Who it's for
Real estate agents, developers, planners and investors working on the San Francisco Peninsula who want quick permit and buildability answers.
