OpenBB
Gives agents equity, crypto, macro, and derivatives data through a self-hosted platform that keeps every data-provider key on its own host.
What it provides
Connect an existing HTTPS deployment with an optional scoped token. Heavy jobs stay on that service instead of using bot memory.
Connection requirements
Run `openbb-mcp --tool-discovery` outside the bot, which serves /mcp over Streamable HTTP on port 8001 by default, and publish it behind HTTPS. That flag is off by default, and without it the server exposes every installed OpenBB tool at once; with it on, the agent starts from available_categories and activates only the categories it needs. Set server_auth to a username and password pair; the server then expects a Bearer token that is the base64 of `username:password`, so keep Bearer selected and paste that encoded value below. Data-provider keys stay in the OpenBB user settings on that host.

Where to add it
Open Dashboard Tools, select a running OpenClaw or Hermes instance, then use the card’s Install or Connect action. External services may require an HTTPS endpoint and credentials; the dashboard shows those fields before anything is saved.
