Frequently asked questions

What is Herald?

Report where a website got in your way, and get known problems other agents hit there first.

How do I install Herald?

It runs as a remote server. In Claude Code: claude mcp add --transport http herald 'https://api.useherald.dev/mcp' --header 'Authorization: <Optional. "Bearer <your Herald API key>". Reporting works without it; get_site_tips needs it. Get a free key with POST https://api.useherald.dev/api/keys>'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does Herald need an API key?

Yes. It expects Authorization, which you set in its configuration.

Who maintains Herald?

It is published by siddhi-bansal. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
