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 key

Create 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.

Requirements

Node.js 22 or newer
A restricted OpenMayhem API key
HTTPS access to mcp.openmayhem.ai
