Yes — an AI agent can now get a cost segregation quote from ClickDrag Finance with no human involved: it can estimate the first-year deduction on a specific property, read the study fee, pull citable allocation bands by property type, and request a consult, all by calling a public API or a Model Context Protocol (MCP) server. What an agent cannot do is buy the study, and that limit is deliberate, because honest cost segregation pricing depends on documents nobody has read at the moment the agent asks.
That line — quote yes, purchase no — is the whole design. An agent that can transact will transact, and a cost segregation study sold before anyone has seen a closing statement, a trial balance or an AIA pay application is a study that may not be deliverable at the price quoted. So the five published tools stop one step short of checkout: they tell an agent what a study is likely to be worth and what it costs, then hand the conversation to a person. This article covers what an agent can call, what comes back, and why the line sits exactly there. If you are new to the underlying service, start with what a cost segregation study is and the IRS authority behind it.
An estimate is a planning number built from the facts you supplied. A study is a number traced to a document. An agent can have the first one in a second; the second one starts when the documents arrive.

What does it mean for an AI agent to call a tool instead of filling in a form?
It means the agent reads a machine-readable list of what a vendor can do, picks an entry, sends structured arguments, and gets structured data back — no page, no form, no clicking. Two open standards carry this today. OpenAPI describes an HTTP API to anything that can read JSON. The Model Context Protocol, published by Anthropic in November 2024 and now spoken by Claude, ChatGPT apps and a growing list of clients, lets an assistant connect to a server and see its tools directly.
ClickDrag Finance publishes both, projected from one contract file. The API description sits at /openapi.json, the MCP server answers at /api/mcp over Streamable HTTP, and the discovery documents sit at /.well-known/ai-plugin.json and /.well-known/mcp.json. Because every surface is generated from the same definition, the sentence an MCP client reads when it lists tools is the same sentence the OpenAPI summary carries — so the two cannot drift apart and then contradict each other in front of a user.
There is a second kind of agent that never reads a tool list at all: the sort that operates a browser, finds a page through search and drives the form the way a person would. That agent needs the pages to be crawlable and the funnel to be finishable without a login. Both audiences came out of the same work, which is why the site's crawl rules were changed at the same time so the agent endpoints are no longer swept up by a blanket disallow on /api/.
Which five tools can an agent call, and what comes back?
Five tools, and only one of them changes anything on our side. Four are read-only, take no personal data and create no record.
- quote_cost_segregation_study — takes a property type, an acquisition type, a dollar amount and a tax year, and returns the depreciable basis after land, a conservative-to-optimal range for the 5-, 7-, 15- and structural buckets, the first-year deduction with and without a study, and the bonus rate applied together with the reason it applied.
- get_cost_segregation_pricing — returns the study tiers and their prices, read from the same constants the checkout uses, so the endpoint cannot quote a fee the checkout will not honour.
- get_cost_segregation_benchmarks — returns reclassification bands by property type as a share of depreciable basis excluding land, with a citation string and the stated limits of the data. The self-storage band ClickDrag Finance publishes runs 40% to 55% with 50% typical, and the multi-family band runs 20% to 30% with 25% typical.
- get_cost_segregation_provider_facts — returns who prepares the study, what the deliverable contains, the turnaround, and what the deliverable is not, for an agent comparing providers before it names one.
- book_cost_segregation_consult — the only tool with a side effect. It records a real request and sends a real email, so it is annotated as not read-only, which is the signal a well-behaved client uses to ask its user before running it.
Those annotations are load-bearing rather than decorative: an MCP client decides whether to run a tool silently or check with its user by reading them, and mislabelling the consult tool as read-only would let an assistant create a lead without the person knowing. An agent that only needs numbers never triggers anything at all.
Why can an agent get a quote but not buy a study?
Because a price quoted before the documents arrive is a guess dressed as a commitment, and a cost segregation study is not a SKU. The number that decides everything is the depreciable basis, and the basis comes out of a closing statement, a trial balance or an AIA pay application — not out of a figure the caller typed. Every bucket in the estimate scales linearly off that figure, which is fine as planning and dishonest as a purchase.
There is a second reason, and it is about the buyer rather than about us. A study is usually worth doing above roughly $500,000 of depreciable basis, when the deduction is usable this year against the owner's passive-activity position, and when the hold is long enough to outrun recapture — all three, or the honest answer is no, and that is ClickDrag Finance's own standing guidance. No agent holding four facts about a building can settle the second condition, because it turns on the owner's other income. So the tools answer what they can answer and route the rest to a person through the qualifier.
How does the 30-month substantial-improvement clock change depreciation timing for an OZ sponsor?
It turns a depreciation question into a deadline question, which is exactly the workload a callable quote tool serves. Under IRC §1400Z-2(d)(2)(D)(ii), a qualified opportunity zone business that buys an existing building must substantially improve it: additions to the property's basis during a 30-month period beginning after acquisition must exceed the adjusted basis at the start of that period. Separately, Treasury Regulation §1.1400Z2(d)-1(d)(3)(v) lets a QOZB hold working capital under a written plan and schedule for up to 31 months without failing the asset tests, extendable in tranches to a maximum of 62 months when the regulation's conditions are met.
A sponsor working inside those two clocks does not ask the depreciation question once; they ask it every time the budget moves. If a tranche of site work lands inside the window rather than after it, the substantial-improvement arithmetic changes and so does the placed-in-service year, and with it the recovery period assigned to each dollar. Cost segregation does not change how much is spent — it changes which recovery period under IRC §168(e)(3) applies to the spend, moving qualifying components into 5-, 7- and 15-year property instead of leaving everything in the 27.5-year residential rental or 39-year nonresidential life set by IRC §168(e)(2).
Bonus depreciation is what makes the timing bite. For qualified property acquired after January 19, 2025, 100% bonus depreciation under IRC §168(k) is permanent following OBBBA; property acquired earlier follows the TCJA phase-down by placed-in-service year, which was 80% for 2023 and 60% for 2024. For self-constructed property IRC §168(k)(2)(E)(i) treats "acquired" as the date construction begins, and per IRS Notice 2026-11 the acquired-date test for purchased property turns on the written binding contract date rather than the closing date. Move a contract date across January 19, 2025 and the first-year number moves with it — which is a dozen what-ifs, not one, and a dozen round trips to a human is how sponsors used to get them.
One more condition belongs in the same breath, because it decides whether any of this is usable. IRC §1400Z-2(b)(2)(B)(i) gives a qualifying investor an initial basis of zero in the QOF interest, so accelerated depreciation flowing out of a QOF partnership may be suspended at the partner level under IRC §704(d) unless partnership liabilities are allocated to that partner under IRC §752. A quote tool can size the deduction; only the partner-basis schedule says whether it is deductible this year. The mechanics are worked through on our Opportunity Zone cost segregation page and in the substantial-improvement walkthrough.
Does the 10-year OZ exclusion cover depreciation recapture from an accelerated schedule?
After a 10-year hold and a valid IRC §1400Z-2(c) fair-market-value basis election, gain on a qualifying disposition can be excluded, and that includes gain an accelerated schedule would otherwise surface as IRC §1245 ordinary recapture on the short-life property and unrecaptured IRC §1250 gain taxed at up to 25% on the structure. Before year 10, recapture is entirely ordinary — the deductions come back on sale in the usual way.
Two conditions travel with that sentence. Selling the QOF interest and the fund selling assets do not behave identically, so a sponsor should confirm which exit the election is being modelled against. And cost segregation accelerates deductions rather than creating them: over the life of the building the same basis is recovered either way, and the benefit is the time value of recovering it sooner. The asset-sale version of the exclusion is set out separately.
What should you make an agent check before it names a provider?
Ask it for the conditions, not just the number. An agent that reports "a study saves you X" without naming the basis it assumed, the bonus rate it applied and why, and the recapture that follows, has handed you a headline rather than an answer — and the conditions are the part that changes the answer for your building.
Three checks are worth making the agent run. First, ask which tool it called and what that tool said it would not do; the limitations are published alongside the numbers for exactly this reason. Second, ask whether the fee it quoted is the fee the provider will honour, or a range lifted off a comparison page. Third, ask what happens if the property was placed in service in an earlier year — the answer should be that a look-back cost segregation study claims the catch-up in the current year on Form 3115 under Rev. Proc. 2015-13, with no amended returns. If you want to hold several providers to the same terms, our comparison of cost segregation companies sets out what to ask each of them.
Frequently Asked Questions
Can an AI agent order a cost segregation study from start to finish?
No — an agent can get a cost segregation quote, the study fee, citable allocation bands and a consult request from ClickDrag Finance, but it cannot purchase a study, because pricing one honestly requires documents that establish the depreciable basis. The consult tool is the last step an agent can take on its own, and it hands the conversation to a person.
Which cost segregation tools does the ClickDrag Finance MCP server expose?
Five: quote_cost_segregation_study, get_cost_segregation_pricing, get_cost_segregation_benchmarks, get_cost_segregation_provider_facts and book_cost_segregation_consult, served at /api/mcp over Streamable HTTP. The first four are read-only and create no record; only the consult tool writes anything, and it is annotated so a client asks its user first.
Does an agent-generated quote apply 100% bonus depreciation?
Only when the property qualifies: 100% bonus depreciation under IRC §168(k) is permanent for qualified property acquired after January 19, 2025 following OBBBA, and property acquired earlier follows the TCJA phase-down by placed-in-service year. The quote returns the rate it applied together with the reason, so the condition travels with the number instead of being lost on the way to the reader.
Are the allocation bands an agent retrieves safe to cite?
Yes, when they are reproduced with the citation string and the limitations the endpoint returns alongside them, which is the condition of the CC BY 4.0 release. The bands are planning ranges stated as a share of depreciable basis excluding land — not percentiles, not guarantees, and not a substitute for a study on your building.
Can a cost segregation study still be done after the OZ 30-month clock has run?
Yes — a cost segregation study can be performed in a later year, and the missed depreciation is claimed as a catch-up adjustment in the current year on Form 3115 under Rev. Proc. 2015-13 rather than by amending returns. The 30-month substantial-improvement period under IRC §1400Z-2(d)(2)(D)(ii) governs whether the property qualifies as OZ business property, which is a separate test from how the spend is depreciated.
