Review first — review before installing

Open the source and read safety notes before installing.

Safety notes

  • Unla can expose existing MCP servers and REST APIs as new MCP endpoints, so the final tool surface depends on every imported config.
  • Generated endpoints may proxy read/write API operations; review tool descriptions and permissions before connecting an autonomous agent.
  • The upstream README notes that Unla is under rapid development and that documentation can lag behind implementation.
  • Replace default admin credentials and secrets before exposing the management UI or gateway outside a trusted development network.
  • Hot-loaded gateway configuration, multi-tenant routing, OAuth pre-authentication, and management UI access should be governed like production API infrastructure.

Privacy notes

  • Unla may receive prompts, tool names, tool arguments, REST API parameters, upstream MCP responses, generated endpoint metadata, logs, admin credentials, JWT secrets, OAuth tokens, and configuration history.
  • Imported REST API and MCP server configs can include private upstream URLs, headers, tokens, tenant identifiers, and service credentials.
  • Persisted config backends and container logs may retain sensitive endpoint definitions and operational metadata.
  • Do not commit real gateway configs, API credentials, admin passwords, JWT secrets, OAuth client secrets, or exported tenant data.

Prerequisites

  • Docker available for the all-in-one deployment, or Kubernetes and Helm if using the packaged cluster deployment.
  • Administrator username, administrator password, and JWT secret replaced before first start.
  • At least one existing MCP server or REST API configuration ready to import into the gateway.
  • Network, TLS, reverse proxy, and port exposure reviewed before sharing generated MCP endpoints.
  • Storage choice and config persistence model reviewed for disk, SQLite, PostgreSQL, or MySQL backed deployments.

About this resource

Content

Unla is a Go-based MCP gateway for converting existing MCP servers and REST APIs into managed MCP endpoints without changing the upstream service code. It can proxy MCP servers, map REST API definitions into MCP tools, and expose the result through SSE or Streamable HTTP endpoints.

The project includes an all-in-one container, a management UI, configuration examples, config persistence options, hot reload support, OAuth pre-authentication, and Kubernetes or Helm deployment assets. It is most useful when a team wants one operational gateway for several MCP-facing integrations instead of wiring each MCP client directly to every upstream server or API.

Source Review

These sources were reviewed on 2026-06-05. Prefer the live repository, README, environment example, gateway configs, deployment files, release page, container package page, and documentation site for current setup, supported transports, management UI behavior, and upgrade notes.

Features

  • Convert REST API configurations into MCP tools.
  • Proxy existing MCP servers behind Unla-managed endpoints.
  • Expose MCP SSE and Streamable HTTP transports.
  • Serve a browser-based management UI for adding and editing gateway configs.
  • Persist configuration through disk, SQLite, PostgreSQL, or MySQL.
  • Hot reload configuration through signals, HTTP, or Redis PubSub.
  • Support multi-tenant deployment patterns and recoverable sessions.
  • Use OAuth-based pre-authentication for MCP servers.
  • Deploy through Docker, Kubernetes, or Helm.

Installation

The README documents an all-in-one container for quick starts:

docker run --name unla \
  -p 8080:80 \
  -p 5235:5235 \
  -e ENV=production \
  -e APISERVER_JWT_SECRET_KEY=YOUR_RANDOM_SECRET \
  -e SUPER_ADMIN_USERNAME=YOUR_ADMIN_USER \
  -e SUPER_ADMIN_PASSWORD=YOUR_ADMIN_PASSWORD \
  ghcr.io/amoylab/unla/allinone:latest

After startup, sign in to the management UI, add an MCP server or REST API configuration, and connect your MCP client to the generated /sse or /mcp endpoint for that server namespace. Replace the placeholder secret and administrator credentials before using the service with real integrations.

Use Cases

  • Put a managed MCP gateway in front of several internal MCP servers.
  • Convert legacy REST APIs into MCP tools through YAML configuration.
  • Provide separate gateway endpoints for teams, tenants, or environments.
  • Test API-to-MCP mappings through the built-in management UI.
  • Add OAuth pre-authentication and centralized routing before MCP traffic reaches upstream services.
  • Package an MCP gateway with Docker, Kubernetes, or Helm for repeatable deployment.

Safety and Privacy

Unla is access infrastructure. Treat every imported API and downstream MCP server as part of the exposed tool surface. Generated endpoints should stay behind trusted network, TLS, authentication, and tenant-boundary controls until the mapped tools have been reviewed.

The gateway can retain sensitive configuration and route sensitive tool traffic. Protect the management UI, container environment, config persistence backend, logs, OAuth settings, upstream headers, and imported API definitions. Keep real admin credentials, JWT secrets, API tokens, OAuth secrets, and tenant-specific configs out of repositories and PR discussions.
