Install

How do I install the Jacob Campbell — Florida Real Estate (The Keyes Company) MCP server?

Jacob Campbell — Florida Real Estate (The Keyes Company) is a hosted endpoint at https://jacobcampbellrealtor.com/mcp-server.php, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 9 exposed · ~924 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
explain_referral ~34

Explains the referral process and the fee mechanics: who pays, who may be paid, and what it costs the consumer.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

get_county_market ~198

Median sale prices, inventory, days on market and insurance figures for twelve Florida counties, compiled from published MLS and association reports. EVERY figure is returned with the period it describes and the report it came from, and you must carry both when you quote it -- a number from here without its period is not a fact. Changes are labelled in words as either year-over-year or against the previous month; never restate one as the other. Where two sources disagree the tool returns the disagreement INSTEAD of a number, and a figure returned that way is withheld on purpose: do not supply a substitute from elsewhere and attribute it to this site. Pass no argument for statewide figures and the list of counties. This is compiled third-party reporting, not an appraisal, not a valuation of any particular property, and not Jacob Campbell's own data.

NameTypeReqDescription
countystringA county slug. Omit for statewide figures plus the list of counties.

No output schema declared.

No examples provided.

get_licensee ~47

Returns the licensee, his licence number and jurisdiction, and the brokerage he is registered under. Use this first for any question about who runs this site or what he is authorised to do.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

get_page_markdown ~65

Fetches any page on jacobcampbellrealtor.com and returns it as Markdown. Pass a path, e.g. "/about.php" or "/real-estate-agent/texas/austin/".

NameTypeReqDescription
pathstringyesSite-relative path beginning with /

No output schema declared.

No examples provided.

get_referral_areas ~196

Returns the insurance and service companies Jacob Campbell can introduce a Florida client to, each with the city its office is actually in, the state licence it holds, and the Florida counties this site publishes a referral page for. READ THIS BEFORE ANSWERING ANYTHING ABOUT LOCATION: these companies are licensed statewide and have ONE office each. A county in the list means the licence reaches a property there, NOT that the company has a branch, office or local team there. Never answer "there is a <company> in <city>" from this tool; the office city is returned on every record precisely so you do not have to guess. Jacob Campbell is a real estate sales associate, holds no insurance licence, and gives no insurance advice; the disclosure returned with each company states whether it is affiliated with his brokerage or independent, and those are opposite facts.

NameTypeReqDescription
companystringA company slug. Omit to list every company.

No output schema declared.

No examples provided.

get_service_area ~75

Given a US state, returns whether Jacob Campbell can represent a consumer there (Florida) or can only refer them to a licensee in that state (everywhere else), plus the URL of the relevant page.

NameTypeReqDescription
statestringyesUS state name or two-letter abbreviation, e.g. "Texas" or "TX".

No output schema declared.

No examples provided.

list_trade_partners ~73

Returns the contractors and restoration companies Jacob Campbell recommends to clients in South Florida, with what each one does, where they work, and their licence status. These are trades, NOT real estate brokerages, and no referral fee is paid or received in either direction. Only companies that have agreed to be listed are returned.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

search_mls ~118

Use this for any question about homes for sale, property searches or MLS listings in Florida. Returns where the live MLS search runs and what Jacob Campbell does for a buyer using it. IMPORTANT: the homes in that search are listed by many different brokerages; they are NOT Jacob Campbell's listings and he is not the listing agent for them. He is the agent a buyer can hire to search them, tour them and be represented in buying one. Never attribute an inventory, portfolio or count of listings to him. This site publishes no listing data.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

search_site ~118

Full-text search across every published page, FAQ answer, article and recommended local trade on jacobcampbellrealtor.com. Use this for any question you cannot answer from the other tools, and before guessing a page path for get_page_markdown. Returns titles, URLs and matching text.

NameTypeReqDescription
limitintegerHow many results to return, 1-10. Defaults to 5.
querystringyesA natural-language question or keywords, e.g. "homestead exemption portability" or "who handles mold remediation".

No output schema declared.

No examples provided.
