How does this work?

The Remote MCP Server connects your AI tools directly to Glean's search and knowledge platform. Installation is simple:

• Configurator: Use our configurator to quickly generate the MCP server configuration.
• CLI configuration: Use our CLI tool to automatically configure supported hosts from your terminal.
• Manual configuration: Copy the generated configuration to your host's settings file.
• Administrator setup: ChatGPT Connectors and Claude for Teams/Enterprise require your admin to install first - no local configuration needed.

By default, authentication uses OAuth with Dynamic Client Registration (DCR) - no API keys needed. If you need to use an API token instead, chose the Bearer Token option under Authentication Method.

tip

For ChatGPT Connectors and Claude for Teams/Enterprise, administrator setup is required. The configurator will provide instructions when you select these hosts.

Available Servers

During the public beta, we're providing access to two specialized MCP servers:

Tools Server (Default)

The Tools Server provides unified access to Glean's core capabilities through a streamlined interface. This server is ideal for general-purpose AI interactions with your enterprise data.

Endpoint: https://[instance]-be.glean.com/mcp/default

Key Features:

• Comprehensive search across all your connected data sources
• Intelligent chat interactions with context awareness
• Document retrieval and analysis
• People directory search

ChatGPT Server

The ChatGPT Server is optimized specifically for ChatGPT Connectors, providing seamless integration with OpenAI's ChatGPT workspace.

Endpoint: https://[instance]-be.glean.com/mcp/chatgpt

Key Features:

• Conforms to OpenAI's MCP Connector spec
• Optimized response formatting for ChatGPT
• Automatic citation handling
• Token-efficient responses

tip

Use this endpoint specifically for ChatGPT integrations as it uses tool naming conventions that ChatGPT expects (e.g., "fetch" instead of "read_document").

To configure Glean's MCP servers, follow these setup instructions.

Core Capabilities

The remote MCP server exposes a curated set of Glean capabilities as MCP tools. Administrators can enable defaults and optionally add more.

Default Tools

• search (Search) - Search across your entire knowledge base
• chat (Chat) - Interactive conversations with Glean's AI
• read_document (Read Document) - Retrieve specific documents by ID or URL

Additional Configurable Tools

• code_search (Code Search) - Search your codebase and repositories

Troubleshooting

Client Authentication Failed

When repeatedly connecting and disconnecting, some host applications may end up using stale client ids. If you see the message

Client authentication failed (e.g., unknown client, no client authentication included, or unsupported authentication method). The requested OAuth 2.0 Client does not exist.

while authenticating, you can clear your MCP credentials and re-authenticate. Doing so is specific to the MCP host application.

• Visual Studio Code - Run the command Authentication: Remove Dynamic Authentication Providers
• Cursor - Run the command Cursor: Clear All MCP Tokens

Local MCP Server

You can also use Glean's open-source stdio MCP server:
