Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security83
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability80
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1055 tokens (~117/item across 9 items; 9 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management90
- Stability observed for 27 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 9 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

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 →
explain_referral How an out-of-state referral works ~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 Florida county housing-market figures ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| county | string | – | A county slug. Omit for statewide figures plus the list of counties. |
No output schema declared.
No examples provided.
get_licensee Who Jacob Campbell is ~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 Read a page as 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/".
| Name | Type | Req | Description |
|---|---|---|---|
| path | string | yes | Site-relative path beginning with / |
No output schema declared.
No examples provided.
get_referral_areas Companies Jacob Campbell refers clients to, and where ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| company | string | – | A company slug. Omit to list every company. |
No output schema declared.
No examples provided.
get_service_area Where he works, and where he refers ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| state | string | yes | US state name or two-letter abbreviation, e.g. "Texas" or "TX". |
No output schema declared.
No examples provided.
list_trade_partners Local trades he recommends ~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 Search Florida MLS listings with him as the buyer's agent (they are not his listings) ~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 Search this 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.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | How many results to return, 1-10. Defaults to 5. |
| query | string | yes | A natural-language question or keywords, e.g. "homestead exemption portability" or "who handles mold remediation". |
No output schema declared.
No examples provided.
