Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00088 | $0.02448 |
| Opus 5.5 | $0.00035 | $0.00979 |
| Sonnet 5.5 | $0.00018 | $0.00490 |
| Haiku 4.5 | $0.00009 | $0.00245 |
Grade A, and why
fabrica scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Fabrica
Fabrica puts US land onchain. A trust holds title at the county; an ERC-1155 token on Ethereum is the beneficial interest in that trust. An authorized transfer of the token transfers the beneficial interest in the trust; the trust keeps title. A token held by a lending, escrow or bridge contract, or moved without the owner's authorization, does not move beneficial ownership. Owners can sell, buy and borrow against land through the DeFi lending pool.
Connect
The Fabrica MCP server is read-only, public, and needs no key:
- Ethereum mainnet (real properties):
https://mcp.fabrica.land/mcp - Sepolia testnet (test tokens):
https://mcp-testnet.fabrica.land/mcp
Everything in this file about trusts, ownership, deeds, taxes and obligations applies to Ethereum mainnet only. On Sepolia, tokens are test tokens: holding or transferring one is not ownership of any real property or of a beneficial interest in a trust, and adding a parcel there creates no trust and records no deed. Every Sepolia result (Property checks, tax status, valuations, loans) is test data: label it so and draw no real-world conclusion from it.

Source: https://github.com/fabrica-land/fabrica-mcp. The server also offers the four loops below as MCP prompts (due_diligence, work_parcel_list, wallet_review, how_to_add_land).
Tools
| Tool | What it answers |
|---|---|
search_land |
Properties by location, size, Property checks, listing status, price, price per acre, distance from a point (near); sorted with sortBy |
get_land_property |
One property: location, owner wallet, valuation, listing, loans, operating agreement link |
get_land_valuation |
Every value held for a property, each with its source, date and confidence, and the pool's oracle state |
get_land_trust_documents |
The legal record: the trust, the trust agreement (name, version, link), legal description, parcel identifiers, deed reference and owner-uploaded documents |
get_land_tax_status |
Whether the property's taxes are current, past due or unknown per Property checks, and whether that limits borrowing |
get_land_order_book |
Listings and offers for one property, with prices, expiry and any loan on it |
get_land_boundary |
Parcel boundary as GeoJSON |
get_land_map_image |
Map image of the parcel |
explain_property_checks |
What each verification group's value means, decoded from the numeric encoding of Property checks (pass counts come from get_land_property's propertyChecks) |
estimate_land_borrowing |
What the DeFi lending pool would lend against a property, and what limits it (limits.limitedBy): a small amount is often the pool's free liquidity, not a valuation. toRaise says what would raise it: each lever, what it would allow, and the step that moves it |
get_fabrica_lending_market |
Loans, pool liquidity, average APR |
get_fabrica_loan_book |
What has been lent, at what loan-to-value (against today's estimate), where, and how many were repaid or liquidated |
get_land_portfolio |
A wallet's holdings, credit history and loans |
get_land_portfolio_map_image |
Map of a wallet's holdings |
get_land_activity |
Transfers, sales and loans for a property or wallet; with no filter, the newest across the network |
get_fabrica_stats |
Protocol-wide counts and totals |
ask_fabrica |
Cited passages from Fabrica's docs, help center and trust agreement for how Fabrica works |
find_us_parcel |
Any US address or parcel number: the parcel, whether it is on Fabrica, and the on-ramp link if not |
check_county_coverage |
Whether a county (or state) can be added through the on-ramp, and what it asks for: deed and forms, notarization and witnesses, questions, steps. From a table of the on-ramp rules with an as-of date |
contact_fabrica_support |
When the docs do not answer or a person is needed: the help center section, the support email and a prefilled email draft. Sends nothing; the person sends it |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

fabrica is a skill published in the GitHub repository fabrica-land/fabrica-mcp (0 stars, last pushed today), licensed MIT. It adds 88 tokens to every session and 2,448 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-18.
