Give a Microsoft Foundry agent our MCP tools

Foundry agents can call any remote MCP server through the MCP tool. Store a free key as a project connection, point the tool at our server, and your agent can check tokens, gas fees, companies and packages.

Add it to Claude or Cursor free (30 seconds) See a live answer first

Set it up

Get a free key. On the set-up page, press the free key button and copy the key.
Create a Custom keys connection. In your Foundry project, open the connected resources and create a connection of type Custom keys. Add the key name Authorization with the value Bearer <your key>.
Add the MCP tool to your agent. Set server_label to aayat, server_url to https://aayatai.com/mcp (or a themed set such as /mcp/crypto) and project_connection_id to your connection.
Choose approvals. require_approval set to always asks before every call; set it to never once you trust the tools you've allowed (you can limit them with allowed_tools).

from azure.ai.projects.models import MCPTool

tool = MCPTool(
    server_label="aayat",
    server_url="https://aayatai.com/mcp/crypto",
    require_approval="always",
    project_connection_id="aayat-key",  # Custom keys: Authorization = Bearer <your key>
)

Prefer OpenAPI?

Every tool is also a plain HTTP endpoint, described in our OpenAPI file. Send the same key as Authorization: Bearer <key> and each call is paid from your credits.

Paying for calls

One free key is shared by everyone who uses your agent: its 20 free calls a day are for trying it out. For real use, top up prepaid credits on the same key; each call then costs its listed price, and failed calls are never charged.

Microsoft documentation

Connect agents to MCP server endpoints in the Foundry docs.

Live example

What your agent gets back: a live package check

Free, no sign-up: a real answer from our own health check for this input. Your own questions cost $0.005 a call, and the first 20 a day are free in Claude or Cursor.

https://aayatai.com/package/check?ecosystem=npm&name=express&version=4.21.2

Ask your AI assistant

Once it's added, just ask in plain words. For example:

Check express 4.21.2 on npm for known vulnerabilities before we add it.

Questions people ask

Do I need an Azure Marketplace offer?

No. Foundry's MCP tool connects to our server directly by URL. You pay us per call with prepaid credits, not through your Azure bill.

Where does the key go?

In a Custom keys project connection, as Authorization = Bearer <key>, referenced by project_connection_id. Foundry sends it as a header on every call.

Can I restrict which tools the agent sees?

Yes: use a themed endpoint (fewer tools) and Foundry's allowed_tools list.

How much does it cost?

Each tool has its own price per call, listed below and on the pricing page. Failed calls are never charged.
