MCP Servers

Model Context Protocol (MCP) servers expose Confidence operations as tools that an AI assistant can call. This page lists the public Confidence MCP servers and shows how to connect them. For a guided setup, see Set Up Confidence for Your AI Assistant.

The Confidence MCP servers are experimental. Tools and their parameters can change.

Servers

All servers use streamable HTTP as the transport.

Server	URL	Authentication	Use it to
Flags	`https://mcp.confidence.dev/mcp/flags`	Required. Sign in to Confidence from your AI assistant.	Manage clients, flags, rules, context schemas, metrics, warehouses, events, and session recording policies
Experiments	`https://mcp.confidence.dev/mcp/experiments`	Required. Sign in to Confidence from your AI assistant.	Find experiments and read their configuration and results
Documentation	`https://confidence.spotify.com/docs/mcp`	None	Search and read the Confidence documentation
Docs and SDK guides	`https://mcp.confidence.dev/mcp/docs`	None	Search the documentation and get SDK integration guides, local resolve guides, and code snippets

For every tool a server exposes, follow the link in the Server column.

MCP Servers and the Confidence Agent

The MCP servers and the in-app Confidence Agent are separate tools:

The MCP servers run inside your own AI assistant, such as Claude Code, Codex, Cursor, or VS Code. To create a metric with an assistant, use the Flags MCP server. The Confidence Agent doesn’t create metrics.
The Confidence Agent runs inside the Confidence app. It covers jobs that MCP doesn’t, such as creating and launching experiments. See Work with the Confidence Agent.

Integration Setup

Set Up the Documentation MCP Server

The Documentation MCP server gives your AI assistant access to Confidence documentation. It requires no authentication, uses streamable HTTP as the transport, and its URL is https://confidence.spotify.com/docs/mcp.

Claude Code
Codex
Cursor
VS Code

claude mcp add --transport http confidence-docs https://confidence.spotify.com/docs/mcp

codex mcp add confidence-docs --url "https://confidence.spotify.com/docs/mcp"

Open the Command Palette

Use Command + Shift + P (Ctrl + Shift + P on Windows) and search for Open MCP settings.

Add the server

Select New MCP Server and add the following to the mcpServers JSON:

"confidence-docs": "https://confidence.spotify.com/docs/mcp"

Create the .vscode directory

Create a .vscode directory in your workspace root if it doesn’t exist.

Create mcp.json

Create a file named mcp.json in the .vscode directory.

Add the server configuration

Add the confidence-docs server to your configuration:

{
  "servers": {
    "confidence-docs": { "url": "https://confidence.spotify.com/docs/mcp" }
  }
}

Start the server

Click Start next to the MCP server name in the JSON file to start it.

Set Up the Flags MCP Server

The Flags MCP server lets your AI assistant create and manage feature flags. It requires authentication, so allow access from the IDE or developer tool where you use it. The server uses streamable HTTP as the transport and its URL is https://mcp.confidence.dev/mcp/flags.

Claude Code
Codex
Cursor
VS Code

claude mcp add --transport http confidence-flags https://mcp.confidence.dev/mcp/flags

After adding, open Claude Code, run /mcp and select confidence-flags to authenticate.

codex mcp add confidence-flags --url https://mcp.confidence.dev/mcp/flags
codex mcp login confidence-flags

Open the Command Palette

Use Command + Shift + P (Ctrl + Shift + P on Windows) and search for Open MCP settings.

Add the server

Select New MCP Server and add the following to the mcpServers JSON:

"confidence-flags": "https://mcp.confidence.dev/mcp/flags"

Authenticate

Click Connect to authenticate.

Create the .vscode directory

Create a .vscode directory in your workspace root if it doesn’t exist.

Create mcp.json

Create a file named mcp.json in the .vscode directory.

Add the server configuration

Add the confidence-flags server to your configuration:

{
  "servers": {
    "confidence-flags": { "url": "https://mcp.confidence.dev/mcp/flags" }
  }
}

Start and authenticate

Click Start next to the MCP server name in the JSON file and authenticate when prompted.

Set Up the Experiments MCP Server

The Experiments MCP server lets your AI assistant explore and analyze A/B tests and rollouts. It requires authentication, so allow access from the IDE or developer tool where you use it. The server uses streamable HTTP as the transport and its URL is https://mcp.confidence.dev/mcp/experiments.

Claude Code
Codex
Cursor
VS Code

claude mcp add --transport http confidence-experiments https://mcp.confidence.dev/mcp/experiments

After adding, open Claude Code, run /mcp and select confidence-experiments to authenticate.

codex mcp add confidence-experiments --url https://mcp.confidence.dev/mcp/experiments
codex mcp login confidence-experiments

Open the Command Palette

Use Command + Shift + P (Ctrl + Shift + P on Windows) and search for Open MCP settings.

Add the server

Select New MCP Server and add the following to the mcpServers JSON:

"confidence-experiments": "https://mcp.confidence.dev/mcp/experiments"

Authenticate

Click Connect to authenticate.

Create the .vscode directory

Create a .vscode directory in your workspace root if it doesn’t exist.

Create mcp.json

Create a file named mcp.json in the .vscode directory.

Add the server configuration

Add the confidence-experiments server to your configuration:

{
  "servers": {
    "confidence-experiments": { "url": "https://mcp.confidence.dev/mcp/experiments" }
  }
}

Start and authenticate

Click Start next to the MCP server name in the JSON file and authenticate when prompted.

Next Steps

Follow a recipe in the MCP Cookbook, for example to set up a flag with targeting or build a metric.
