Cortex Gateway

Cortex Gateway is a remote MCP server: there is nothing to install. Its endpoint is https://mcp.cortex-gateway.dev/mcp, served over Streamable HTTP. In an assistant that accepts remote MCP servers (often under a setting named connectors, integrations or tools), add a new server and give it this URL; in a client configured by file, add it as a remote (HTTP) server with the same URL.

No headers are declared in the registry entry. If the server needs you to sign in, a client that supports MCP authorization opens the service's own sign-in page when it first connects.

It can also run locally from a container image in an OCI registry such as Docker Hub or GitHub Container Registry: ghcr.io/wellknownmcp/cortex-gateway:v0.2.0. The package starts a local server that speaks MCP over Streamable HTTP; the client then connects to it by URL. It reads these environment variables: CORTEX_CANONICAL_URI (required), OAUTH_ISSUER (required), CORTEX_BACKENDS (required) and CORTEX_TECHNICAL_TOKEN (required, secret); set them in the client's configuration for this server.

Derived from the registry entry, not tested here. What the server does, and on what terms, is set by its publisher; check its repository or website before giving it access to your accounts or files. How to add an MCP server to an assistant · Before you connect
