Installation

In SourceWeft

  1. Open Fabrica (Sepolia testnet) in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Other MCP clients

Add this to your client's mcpServers config.

README

Fabrica MCP Server

Give AI agents access to tokenized real property data. Search properties, analyze lending markets, and explore portfolios across tokenized parcels of US land on the Fabrica protocol.

What is this?

Fabrica tokenizes real property (land) as ERC-1155 NFTs on Ethereum. This MCP server lets any AI agent query the full property catalog, lending market, and portfolio data — no API keys required.

Built on the Model Context Protocol (MCP).

Quick Start

Hosted (recommended): nothing to install

Point any MCP client at the hosted server:

NetworkURL
Ethereum Mainnet (real parcels)https://mcp.fabrica.land/mcp
Sepolia Testnet (test properties)https://mcp-testnet.fabrica.land/mcp

Claude (claude.ai and desktop): Settings → Connectors → Add custom connector → paste the URL.

Claude Code:

bash
claude mcp add --transport http fabrica https://mcp.fabrica.land/mcpclaude mcp add --transport http fabrica-testnet https://mcp-testnet.fabrica.land/mcp

Cursor (.cursor/mcp.json):

json
{  "mcpServers": {    "fabrica": { "url": "https://mcp.fabrica.land/mcp" }  }}

Any other client that supports remote MCP servers (Streamable HTTP) works the same way. Add both URLs as two separate servers if you want to try things on testnet before mainnet: the network is fixed per URL, so an agent can never reach mainnet through the testnet server.

Run locally (stdio)

Clone and build:

bash
git clone https://github.com/fabrica-land/fabrica-mcp.gitcd fabrica-mcpnpm installnpm run build

Then configure your MCP client to use the built server:

Claude Code:

bash
claude mcp add fabrica -- node /absolute/path/to/fabrica-mcp/dist/index.js

Claude Desktop (claude_desktop_config.json):

json
{  "mcpServers": {    "fabrica": {      "command": "node",      "args": ["/absolute/path/to/fabrica-mcp/dist/index.js"]    }  }}

Replace /absolute/path/to/fabrica-mcp with the actual path where you cloned the repo.

Example Conversations

"Find me all tokenized properties in Texas"

"What's the current average APR on Fabrica's lending market? How much liquidity does the lending pool have?"

"Do a full due diligence report on property token 12743610130101631987"

"Show me the portfolio for wallet 0x23bc...fce4 — what properties do they own?"

"Give me protocol-wide stats for Fabrica: how many properties, in which states, and total loan volume?"

"How much can I borrow against property token 12743610130101631987?"

"Show me all recent activity for wallet 0x23bc...fce4"

"Explain the confidence score 73242 — what does each digit mean?"

"Show me a map of property token 12743610130101631987"

"Show me a map of all properties in this wallet's portfolio"

Network Selection

The hosted servers are split by URL (see Quick Start). A local server connects to Ethereum Mainnet by default, where properties represent real parcels of US land with real legal consequences. To experiment with test properties first, set FABRICA_NETWORK=sepolia:

Claude Code (Sepolia):

bash
claude mcp add fabrica -e FABRICA_NETWORK=sepolia -- node /absolute/path/to/fabrica-mcp/dist/index.js

Claude Desktop (Sepolia):

json
{  "mcpServers": {    "fabrica": {      "command": "node",      "args": ["/absolute/path/to/fabrica-mcp/dist/index.js"],      "env": { "FABRICA_NETWORK": "sepolia" }    }  }}

Mainnet notice: On mainnet, the MCP server instructs AI agents to inform users that operations have real-world legal and financial consequences — including accepting the role of trustee, potential property liabilities, and tax implications. Agents are directed to review the trust instrument attached to tokens before advising on acquisition.

Sepolia: Test properties only, no real-world implications.

Configuration

All optional — sensible defaults are built in:

VariableDefaultDescription
FABRICA_NETWORKethereumNetwork to operate on (ethereum or sepolia)
FABRICA_API_URLhttps://api.fabrica.land/graphqlFabrica GraphQL API
FABRICA_METASTREET_SUBGRAPH_URLAuto-selected per networkSubgraph for the lending pool contracts (the variable keeps its original name)
FABRICA_MEDIA_URLhttps://media.fabrica.landFabrica media service for map images

Hosting

The hosted servers run on Vercel from this repository: one Vercel project per network, both built with npm run build:vercel (see vercel.json), which emits a single stateless Streamable HTTP function at /mcp and a landing page at /. Set FABRICA_NETWORK in each project's environment (ethereum or sepolia). The same handler (src/http.ts) can run behind any Node HTTP server.
