Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@OpenMayhem MCPshow me available models and their prices"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
OpenMayhem MCP
OpenMayhem's local stdio bridge forwards MCP messages to the hosted OpenMayhem service. It does not bundle a stale catalog: list_models and get_model read the live catalog, availability, capabilities, limits, routes, and prices from OpenMayhem. Account balance and payment logic remain on the hosted service, and the bridge contains no provider data or credentials.
Install
Download openmayhem-mcp-v1.0.0.mcpb from the v1.0.0 release and install it in an MCPB-compatible client. The client asks for a restricted OpenMayhem API key and stores it as a sensitive setting.
Clients that support remote Streamable HTTP can connect directly:
URL: https://mcp.openmayhem.ai/mcp
Header: X-OpenMayhem-API-Key: your restricted OpenMayhem API keyCreate and revoke API keys at openmayhem.ai. Complete setup, tool, payment, and client instructions are at openmayhem.ai/docs/mcp.

Billing
Model discovery, request estimation, token counting, balance checks, job reads, cancellation, and owned-artifact lookup do not spend model credit. Model execution is paid. Every paid tool requires a current estimate and an explicit maximum cost.
The bridge does not calculate charges or handle payment information. Requests use the existing OpenMayhem account, balance, reservation, receipt, and settlement paths.
