### AI overview

The article examines Sierra's internal MCP gateway and argues that its most difficult challenges are authentication, identity, per-tool scopes, consent, and audit rather than MCP protocol design. It also discusses integration work and the lack of standardized gateway behavior.

### Source excerpt

Sierra's MCP gateway iceberg is a field report on agent auth: identity, per-tool scopes, consent, and audit are the submerged mass, and they ship off the shelf.

### AI overview

The article explains the emergence of the Agent Gateway as an architectural component for AI agents. It contrasts traditional API Gateways, which authenticate, govern, route, and deliver requests from clients that already know which API to call, with the needs of AI agents, which receive goals and may require broader governance across agentic workflows.

### AI overview

Harness describes building an MCP Gateway that lets Harness AI Chat access GitHub, Jira, and Confluence through a single governed interface. The gateway uses Harness RBAC, Secret Manager, and Connectors to control access and credentials while supporting distributed operation without dropped sessions.

### Source excerpt

One MCP Gateway lets AI Chat call GitHub, Jira, and Confluence with per-tool permissions, RBAC visibility, and no dropped sessions at scale. | Blog

### AI overview

Harness describes how its Autonomous Worker Agents use delegated identity, per-run ephemeral tokens, inherited RBAC and OPA policy, least-privilege scope filtering, and server-side MCP gateway tool intersection. The design gives agents a bounded subset of the triggering principal's permissions and removes token access when a run ends.
