Artificial Intelligence (AI)
ContextForge, the open source model context protocol gateway from IBM: federate many MCP servers behind one authenticated endpoint, with a registry and admin UI, secured from first boot by cloudimg.
Overview
ContextForge MCP Gateway is an open source gateway, registry and proxy for the Model Context Protocol, the standard that lets AI assistants and agents call external tools. It sits in front of many separate MCP servers and presents them as one authenticated endpoint: it keeps a registry of the servers and the tools they expose, lets you compose virtual servers from a chosen set of tools, and normalises different MCP transports so a client connects once and reaches everything. An admin web interface manages the federated servers, tools and access, so teams get a single controlled front door to their MCP tool estate instead of wiring every assistant to every server by hand.
It suits platform and AI engineering teams who are running more than one MCP server and want central registration, discovery, authentication and auditing over the tools their agents can call, hosted inside their own cloud account.
Why the cloudimg image
cloudimg ships ContextForge secure by default with no surviving default login. On the first boot of every instance a unique administrator password, a JWT signing secret and an encryption secret are generated and written to a root only file, so no two deployments share a credential and the upstream default never governs a running instance. Because the gateway is a credential aggregation point for every server it federates, the gateway and its embedded database are bound to loopback behind a reverse proxy rather than exposed, and unauthenticated requests are refused. To prove the gateway genuinely works out of the box it ships one real reference MCP server on the appliance, pre federated at first boot, and the build verifies a real tool call travelling through the gateway to that server end to end. The base is fully patched with unattended security upgrades enabled, and every deployment is paired with a step by step guide and backed by 24/7 cloudimg support.
Common uses
- One authenticated front door for many MCP servers
