API, SSH, Database, and MCP in one local-first developer workspace

Unfour helps backend developers investigate issues without constantly switching between separate tools. API requests, server access, database inspection, and MCP-assisted workflows share the same local workspace context.

Four capabilities, one troubleshooting context

Each capability works on its own. Together, they preserve the evidence and environment context that a backend investigation needs.

Requests

API Client

Send and organize HTTP requests, inspect complete responses, and bring request evidence into the rest of the investigation.

  • Collections, folders, and saved requests
  • Query, headers, body, and auth
  • Environments, scripts, and OpenAPI
  • Response body, headers, cookies, and timing

Servers

SSH Terminal

Connect to servers, inspect runtime evidence, work with remote files, and reuse multi-step operational tasks.

  • Interactive SSH terminal
  • SFTP file browsing and transfers
  • Command history
  • Reusable multi-step SSH tasks
Explore SSH Terminal

Data

Database Explorer

Inspect schema and data, edit supported rows, and run SQL when an API symptom needs database evidence.

  • SQLite, PostgreSQL, and MySQL
  • Schema and table browsing
  • Data inspection and supported row editing
  • Single or multi-statement SQL
Explore Database Explorer

AI-assisted

MCP Integration

Expose approved local API, SSH, and database capabilities to MCP-compatible AI agents for controlled, evidence-based troubleshooting.

  • Local stdio MCP server
  • Workspace-scoped tools
  • Policy and confirmation boundaries
  • Codex, Cursor, and compatible clients

Follow the issue across the backend instead of rebuilding context

An API error is often only the first clue. Unfour keeps the request, target environment, server evidence, and database state connected in one workspace so each step starts with useful context.

  1. 1. API request
  2. 2. SSH evidence
  3. 3. Database state
  4. 4. MCP-assisted analysis

The workspace stays on your desktop by default

Unfour is a desktop application. Connections, credentials, and workspace context remain local by default, while MCP tools operate through the capabilities and policies exposed by the local Unfour workspace.

Desktop application

Core troubleshooting runs from the Unfour application on your machine.

Local credentials

Saved credentials remain on the device by default and are resolved only for requested operations.

Workspace context

Projects, environments, connections, and tools stay organized around a local workspace.

Approved MCP capabilities

AI agents use the tools Unfour exposes, subject to workspace policy and confirmation checks.
