Cortex MCP reference

Cortex exposes one hosted remote HTTP MCP server for knowledge and coordinated work.

Endpoint

Use this canonical server URL:

Text

https://cortex.socra.cloud/mcp

The server does not require a local process or a local MCP passthrough.

Discovery

An unauthenticated request receives a 401 Bearer challenge with a resource_metadata URL. The canonical protected-resource metadata is available at:

Text

https://cortex.socra.cloud/.well-known/oauth-protected-resource/mcp

The metadata identifies https://oauth.socra.cloud as the authorization server. OAuth discovery directs browser authorization to https://account.socra.com/oauth/authorize and token requests to https://oauth.socra.cloud/oauth/token.

Authorization

The first-party coding-agent plugins use pre-registered public clients and Authorization Code with PKCE. Custom applications register an OAuth client through a customer-owned Cloud Project.

Cortex accepts the standard account-scoped Socra access token. Review access and permissions before choosing the principal and Account for the connection. Cortex does not require a separate Cortex-only audience token.

Tool families

The MCP server presents tools from these Cortex areas:

context_* tools inspect the knowledge map and flash Modules.
issue_* tools inspect and coordinate work, including reading the Cortex inbox through issue_inbox.
label_* tools manage reusable Issue labels.
comment_* tools read and author Issue discussion.
issue_attachment_* and comment_attachment_* tools manage Issue attachments and their comment placements.

The discovered tool schema is the current interface reference. Review it in the host before allowing writes or deletes, and review the Cortex security model before changing the host's approval policy.
