## About

Liner connects an assistant to Liner's search and research services. It offers web search and scholarly search, plus domain searches for legal, finance, medical and business sources. Agent tools return concise cited answers or multi-step research briefs.

It runs as a hosted Streamable HTTP server at https://platform.liner.com/api/v1/mcp. Users sign in with a Liner account through OAuth in the browser and choose which API key the connection bills to. A Liner API key can also be sent as a Bearer token for CI and headless setups.

## What it can do

- Search the web and get titles, URLs and snippets
- Search academic and scholarly literature
- Search legal, finance, medical and business sources
- Get short cited answers to factual questions
- Run multi-step deep research briefs

## Example prompts

- "Find recent papers on solid-state battery electrolytes and list the sources."
- "Search for the latest FDA approvals for GLP-1 drugs."
- "Run deep research on the European market for industrial heat pumps."
- "Look up regulations on drone permits for commercial use in Germany."

## Install

### Claude Code

1. Run this in a terminal, in your project folder:

```bash
claude mcp add --transport http liner https://platform.liner.com/api/v1/mcp
```

2. Start Claude Code, type `/mcp`, pick **liner** and choose **Authenticate**. A browser window opens for the Liner sign-in.

Add `--scope user` to make it available in every project, not just this one.

### Claude Desktop

1. Open **Settings → Connectors** and click **Add custom connector**.

2. Name it **Liner** and paste this URL:

```url
https://platform.liner.com/api/v1/mcp
```

3. Click **Add**, then **Connect**, and sign in when Liner asks.

Claude Desktop’s JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.

### claude.ai

1. Open the connector form on claude.ai. This button fills in the name and URL for you:

[Add to claude.ai](<https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=Liner&connectorUrl=https%3A%2F%2Fplatform.liner.com%2Fapi%2Fv1%2Fmcp>) (opens connector settings)

2. Check that the URL reads `https://platform.liner.com/api/v1/mcp` and click **Add**.

3. Click **Connect** and sign in when Liner asks.

Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under **Organization settings → Connectors**.

### ChatGPT

1. On chatgpt.com, open **Settings → Security and login** and turn on **Developer mode**.

2. Go to `chatgpt.com/plugins` and click **+** to create an app for a remote MCP server.

3. Paste `https://platform.liner.com/api/v1/mcp` as the server URL and choose **OAuth**. ChatGPT sends you to Liner to sign in.

Developer mode is available on the web for Plus, Pro, Business, Enterprise and Education accounts.

### Cursor

[Add to Cursor](<https://cursor.com/install-mcp?name=liner&config=eyJ1cmwiOiJodHRwczovL3BsYXRmb3JtLmxpbmVyLmNvbS9hcGkvdjEvbWNwIn0%3D>) (opens Cursor)

Or add it by hand to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (this project):

`mcp.json`:

```json
{
  "mcpServers": {
    "liner": {
      "url": "https://platform.liner.com/api/v1/mcp"
    }
  }
}
```

Cursor shows **Needs login** next to the server. Click it to sign in.

### VS Code

[Install in VS Code](<https://vscode.dev/redirect/mcp/install?name=liner&config=%7B%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fplatform.liner.com%2Fapi%2Fv1%2Fmcp%22%7D>) (opens VS Code)

Or from a terminal:

```bash
code --add-mcp '{"name":"liner","type":"http","url":"https://platform.liner.com/api/v1/mcp"}'
```

Or commit it to the repo in `.vscode/mcp.json`:

`.vscode/mcp.json`:

```json
{
  "servers": {
    "liner": {
      "type": "http",
      "url": "https://platform.liner.com/api/v1/mcp"
    }
  }
}
```

VS Code asks you to sign in the first time the server starts.

### Devin Desktop

1. Add it to `~/.config/devin/mcp_config.json` (macOS and Linux) or `%APPDATA%\devin\mcp_config.json` (Windows):

`mcp_config.json`:

```json
{
  "mcpServers": {
    "liner": {
      "serverUrl": "https://platform.liner.com/api/v1/mcp"
    }
  }
}
```

2. Refresh the MCP server list in Cascade and sign in when asked.

Devin Desktop is the new name for Windsurf. It reads `serverUrl` (or `url`) for remote servers.

### Codex

```bash
codex mcp add liner --url https://platform.liner.com/api/v1/mcp
codex mcp login liner
```

Or edit `~/.codex/config.toml` directly:

`config.toml`:

```toml
[mcp_servers.liner]
url = "https://platform.liner.com/api/v1/mcp"
```

### Gemini CLI

```bash
gemini mcp add --transport http liner https://platform.liner.com/api/v1/mcp
```

Then, inside Gemini CLI, run `/mcp auth liner` to sign in.

This adds it to the current project. Add `-s user` to use it everywhere.

### Any client

Most clients accept this shape. Some name the URL field differently: `serverUrl` in Devin Desktop, `httpUrl` in Gemini CLI’s settings file.

```json
{
  "mcpServers": {
    "liner": {
      "type": "http",
      "url": "https://platform.liner.com/api/v1/mcp"
    }
  }
}
```

Zed puts servers under `context_servers` in its settings. Cline needs `"type": "streamableHttp"`, or it assumes SSE.

Client only starts local servers? Bridge it with `npx -y mcp-remote https://platform.liner.com/api/v1/mcp`.
