Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http catalog https://omnicost.com/api/mcp --header 'Authorization: Bearer {api_key}'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{

    "catalog": {
      "url": "https://omnicost.com/api/mcp",
      "headers": {
        "Authorization": "Bearer {api_key}"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

Optional Bearer API key. Clients with MCP OAuth can sign in with an Omnicost account instead.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

search_catalog
Search construction-cost items (materials, labor, equipment) by free text. Returns the best matches with median price and vendor count.
get_item
Get one catalog item by id (ci_…): vendors, prices with source and date, and price history.
list_categories
List the catalog categories, each with its parent category's name.
get_decomposition
Cost breakdown of an item: its material, labor and equipment components per unit, with quantities and unit prices. A component's item_id (vsku_…) can be passed back to get_decomposition.

Common questions

Is Omnicost safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 5 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Omnicost MCP server

Construction unit prices with source and date for Spain, the US and the EU, available to AI agents over the Model Context Protocol.

Omnicost is a construction cost catalog and estimating tool. It gathers unit prices for materials, labor and equipment from 208 sources such as public tenders and supplier catalogs, and keeps the source and observed date on every price. The catalog holds about 81,000 priced items, and coverage is strongest in Spain, the United States and the European Union. This repository holds the public listing for the hosted MCP server: its server.json for MCP registries and ready-to-use client configs.

The server itself is hosted by Omnicost. There is nothing to install or run from this repo.


Endpoint	`https://omnicost.com/api/mcp`
Transport	Streamable HTTP
Auth	Sign in with your Omnicost account (OAuth 2.1 + PKCE), or `Authorization: Bearer`
Registry name	`com.omnicost/catalog`
Website	https://omnicost.com

Connect with your Omnicost account

Claude, ChatGPT and Claude Code can connect by signing in. You need a free Omnicost account; no API key to copy.

Claude (claude.ai and Claude Desktop): Settings → Connectors → Add custom connector. Paste https://omnicost.com/api/mcp and click Connect.
ChatGPT: Settings → Apps & Connectors, turn on developer mode and create a connector with the URL https://omnicost.com/api/mcp and OAuth authentication.
Claude Code: claude mcp add --transport http omnicost https://omnicost.com/api/mcp, then run /mcp and pick omnicost to sign in.

The client opens an Omnicost sign-in page. Sign in (or create an account), pick the workspace to connect and approve read-only catalog access. The connection uses that workspace's plan: Omnicost Pro limits on Pro, otherwise the free tier (200 requests a minute, 10,000 a month). Access tokens last 1 hour and refresh on their own for 30 days.

Any other client that supports MCP authorization can do the same: every request to /api/mcp without a key or token gets a 401 with WWW-Authenticate: Bearer realm="omnicost", error="missing_token", resource_metadata="https://omnicost.com/.well-known/oauth-protected-resource", and the authorization server supports dynamic client registration and Client ID Metadata Documents.

Connect with an API key

For clients without OAuth, or for scripts:

Sign up at https://omnicost.com/en and create your workspace.
Open https://omnicost.com/dashboard/mcp and create an organization API key.
Add it to your MCP client config as shown below.

Pay per call without an account (x402)

Agents that pay per call instead of signing in use a separate endpoint, https://omnicost.com/api/mcp/x402. There, initialize, tools/list and ping are free, and each tools/call costs $0.01 in USDC on Base via x402, charged only when the call succeeds. On https://omnicost.com/api/mcp, a request without a key or token gets the 401 that starts sign-in.

Tools

Tool	What it does
`search_catalog`	Semantic search over the catalog. Takes a free-text query (`q`), an optional `limit` (up to 25) and an optional `region`. Returns matching items with median price and vendor count.
`get_item`	Fetches one item (`ci_...` id) with its vendor breakdown and recent prices, each with its source.
`list_categories`	Lists the top-level catalog categories.
`get_decomposition`	Returns the BC3 recipe for an item: the material, labor and machinery components per unit.

For useful results, query items priced in Spain, the US or the EU.

Client setup with an API key

Replace the placeholder with your organization API key. Keep the key out of version control. Clients that support OAuth can skip the key; see above.

Cursor

~/.cursor/mcp.json or .cursor/mcp.json in your project (examples/cursor.mcp.json):

"mcpServers": { "omnicost": { "url": "https://omnicost.com/api/mcp", "headers": { "Authorization": "Bearer ${env:OMNICOST_API_KEY}" } } } }

VS Code

.vscode/mcp.json (examples/vscode.mcp.json). VS Code asks for the key the first time and stores it for you:

"inputs": [ { "type": "promptString", "id": "omnicost-key", "description": "Omnicost API key", "password": true } ], "servers": { "omnicost": { "type": "http", "url": "https://omnicost.com/api/mcp", "headers": { "Authorization": "Bearer ${input:omnicost-key}" } } } }

Claude Desktop

Claude Desktop talks to remote servers through mcp-remote, so you need Node.js installed. Add this to claude_desktop_config.json (examples/claude-desktop.json):

"mcpServers": { "omnicost": { "command": "npx", "args": [ "-y", "mcp-remote", "https://omnicost.com/api/mcp", "--header", "Authorization:Bearer ${OMNICOST_API_KEY}" ], "env": { "OMNICOST_API_KEY": " " } } } }

Any other client

Point a client that supports streamable HTTP at https://omnicost.com/api/mcp. Either let it sign in with OAuth or send the key as a Bearer token in the Authorization header.

Pricing

A free account can connect by OAuth or with an organization API key. Omnicost Pro ($9/week, $29/month or $290/year) includes API and MCP access with 100,000 requests a month. See https://omnicost.com/en/pricing.
