## About

Elmo is an open-source answer engine optimization (AEO) platform. It tracks prompts across AI engines such as ChatGPT, Claude, Perplexity, Gemini, Copilot and Google AI Overviews, and measures visibility, share of voice, sentiment, citations and query fan-out for your brand and competitors.

The MCP server is hosted at app.elmohq.com and uses streamable HTTP. It is meant for assistants such as Claude Code, Cursor, Codex and VS Code. Access needs Elmo credentials; the platform can also be self-hosted. Elmo Cloud starts at $29/mo.

## What it can do

- Query AI visibility data for tracked prompts
- Compare share of voice against competitors
- Review sentiment and position in AI answers
- Inspect citations and cited domains
- Explore query fan-out searches

## Example prompts

- "How often does ChatGPT mention our brand for our tracked prompts?"
- "Which competitors are AI engines recommending instead of us?"
- "Show the most cited domains in our category this month."
- "What is our sentiment trend across engines over the last 30 days?"

## Install

### Claude Code

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

```bash
claude mcp add --transport http elmo https://app.elmohq.com/api/mcp
```

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

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

### Claude Desktop

1. Open **Customize → Connectors**, click **+ Add**, then **Add custom connector**.

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

```url
https://app.elmohq.com/api/mcp
```

3. Click **Add**, then **Connect**, and sign in when elmohq 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=Elmo&connectorUrl=https%3A%2F%2Fapp.elmohq.com%2Fapi%2Fmcp>) (opens connector settings)

2. Check that the URL reads `https://app.elmohq.com/api/mcp` and click **Add**.

3. Click **Connect** and sign in when elmohq 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, go to **Plugins**, select **+**, then **Add custom MCP server**.

2. Enter a name for the server.

3. Under **Connection**, paste `https://app.elmohq.com/api/mcp` as the server URL, then for authentication choose **OAuth**. ChatGPT sends you to elmohq to sign in.

4. Check **I understand and want to continue**, then select **Create as a plugin**.

Whether you can add a custom MCP server depends on your ChatGPT plan and your workspace permissions (in Business workspaces, admins and owners can).

### Cursor

[Add to Cursor](<https://cursor.com/install-mcp?name=elmo&config=eyJ1cmwiOiJodHRwczovL2FwcC5lbG1vaHEuY29tL2FwaS9tY3AifQ%3D%3D>) (opens Cursor)

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

`mcp.json`:

```json
{
  "mcpServers": {
    "elmo": {
      "url": "https://app.elmohq.com/api/mcp"
    }
  }
}
```

Cursor shows **Needs authentication** next to the server. Click the button beside it to sign in.

### VS Code

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

Or from a terminal:

```bash
code --add-mcp '{"name":"elmo","type":"http","url":"https://app.elmohq.com/api/mcp"}'
```

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

`.vscode/mcp.json`:

```json
{
  "servers": {
    "elmo": {
      "type": "http",
      "url": "https://app.elmohq.com/api/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": {
    "elmo": {
      "serverUrl": "https://app.elmohq.com/api/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 elmo --url https://app.elmohq.com/api/mcp
codex mcp login elmo
```

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

`config.toml`:

```toml
[mcp_servers.elmo]
url = "https://app.elmohq.com/api/mcp"
```

### Gemini CLI

```bash
gemini mcp add --transport http elmo https://app.elmohq.com/api/mcp
```

Then, inside Gemini CLI, run `/mcp auth elmo` 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": {
    "elmo": {
      "type": "http",
      "url": "https://app.elmohq.com/api/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://app.elmohq.com/api/mcp`.
