Common questions

Is Linq safe?

It passed 1 of 1 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: LINQ_API_V3_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.82.2) reached the registry today.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Linq API V3 TypeScript MCP Server

It is generated with Stainless.

Installation

Direct invocation

You can run the MCP Server directly via npx:

export LINQ_API_V3_API_KEY="My API Key"

export LINQ_WEBHOOK_SECRET="My Webhook Secret" npx -y @linqapp/sdk-mcp@latest

Via MCP Client

There is a partial list of existing clients at modelcontextprotocol.io. If you already have a client, consult their documentation to install the MCP server.

For clients with a configuration JSON, it might look something like this:

"mcpServers": { "linqapp_sdk_api": { "command": "npx", "args": ["-y", "@linqapp/sdk-mcp"], "env": { "LINQ_API_V3_API_KEY": "My API Key", "LINQ_WEBHOOK_SECRET": "My Webhook Secret" } } } }

Cursor

If you use Cursor, you can install the MCP server by using the button below. You will need to set your environment variables in Cursor's mcp.json, which can be found in Cursor Settings > Tools & MCP > New MCP Server.

VS Code

If you use MCP, you can install the MCP server by clicking the link below. You will need to set your environment variables in VS Code's mcp.json, which can be found via Command Palette > MCP: Open User Configuration.

Open VS Code

Claude Code

If you use Claude Code, you can install the MCP server by running the command below in your terminal. You will need to set your environment variables in Claude Code's .claude.json, which can be found in your home directory.

claude mcp add linqapp_sdk_mcp_api --env LINQ_API_V3_API_KEY="My API Key" LINQ_WEBHOOK_SECRET="My Webhook Secret" -- npx -y @linqapp/sdk-mcp

Code Mode

This MCP server is built on the "Code Mode" tool scheme. In this MCP Server, your agent will write code against the TypeScript SDK, which will then be executed in an isolated sandbox. To accomplish this, the server will expose two tools to your agent:

The first tool is a docs search tool, which can be used to generically query for documentation about your API/SDK.

The second tool is a code tool, where the agent can write code against the TypeScript SDK. The code will be executed in a sandbox environment without web or filesystem access. Then, anything the code returns or prints will be returned to the agent as the result of the tool call.

Using this scheme, agents are capable of performing very complex tasks deterministically and repeatably.

Running remotely

Launching the client with --transport=http launches the server as a remote server using Streamable HTTP transport. The --port setting can choose the port it will run on, and the --socket setting allows it to run on a Unix socket.

Authorization can be provided via the Authorization header using the Bearer scheme.

Additionally, authorization can be provided via the following headers:

Header	Equivalent client option	Security scheme
`x-linq-api-v3-api-key`	`apiKey`	BearerAuth

A configuration JSON for this server might look like this, assuming the server is hosted at http://localhost:3000:

"mcpServers": { "linqapp_sdk_api": { "url": "http://localhost:3000", "headers": { "Authorization": "Bearer " } } } }
