Connect ChatGPT or Claude Code through MCP

MCP connects your assistant to Bold so you can query information with everyday questions, without writing code. For example, you can ask it to find manufacturing orders or check an item’s stock.

Before you start

To connect your assistant to Bold, you need an API key. An administrator can create one in Control panel > Access > API keys. Create a different key for each assistant. This lets you revoke its access without affecting other connections. Keep these details ready during setup:

Field	What to enter
Name	`Bold`
Connection type	`Streamable HTTP`
Server address	`https://api.bold-factory.com/mcp`
Header name	`X-Api-Key`
Header value	Your Bold API key

Use the full address shown in the table. This connection does not require you to sign in to Bold from the assistant.

Connect your assistant

ChatGPT Desktop
Claude Code

Open MCP settings

In ChatGPT Desktop, go to Settings > MCP servers and select Add server.

Enter the Bold details

Enter Bold as the name, choose Streamable HTTP, and paste the server address. Add the X-Api-Key header with your API key as its value. If your settings screen does not offer headers, use Manual configuration below.

Save and check the connection

Save the server and select Restart. Open a local task and type /mcp. If bold appears as connected, setup is complete.

Manual configuration

Open ~/.codex/config.toml. On Windows, it is at %USERPROFILE%\.codex\config.toml. This configuration also works with Codex CLI and the IDE extension.Add this block and replace API_KEY with your Bold key:

[mcp_servers.bold]
url = "https://api.bold-factory.com/mcp"
http_headers = { "X-Api-Key" = "API_KEY" }

Save the file and restart the server in Settings > MCP servers.

These steps apply to local tasks in the desktop app. See the official MCP setup guide for other supported clients.

You need Claude Code installed and access to a terminal.

Add the server

Run this command in the terminal and replace API_KEY with your Bold key:

claude mcp add --transport http --scope user bold https://api.bold-factory.com/mcp --header "X-Api-Key: API_KEY"

This command saves the connection in your personal configuration so you can use it from different projects.

Check the connection

Open a new Claude Code session and run /mcp. Check that bold is connected and that you can see its tools.

See the Claude Code MCP configuration for more options.

Treat the API key like a password: do not share it or store it in files other people can see. If you enter it in a terminal, it may be saved in your command history.

Try a query

Ask the assistant:

Use Bold to show open manufacturing orders.
Include their reference and status. Do not modify any data.

If the assistant returns information from Bold, the connection is working.

If it does not connect

Problem	What to check
It says the key is invalid (`401`)	Copy the full key again without spaces and check that it is still active.
It says you lack permission (`403`)	Ask your Bold administrator to review your key and MCP access.
It cannot find the server (`404`)	Check that you used exactly `https://api.bold-factory.com/mcp`. If it still fails, confirm with Bold that MCP is enabled.
Bold appears disconnected	Restart the server in Settings > MCP servers or open a new Claude Code session.
It asks you to sign in	Check that the header name is `X-Api-Key` and that you pasted your key as its value.

To remove access, disable the corresponding key in Control panel > Access > API keys and remove the server from your assistant’s configuration.
