Let your coding agent verify its own work.

Signadot's MCP server integrates with Cursor, Claude Code, Codex, and others. Agents create sandboxes, run tests, and generate previews through plain English.

Agents generate code. They can't verify it.

Without infrastructure to test against real dependencies, developers become the verification layer and AI productivity gains vanish.
Agents Code Blind
Coding agents don't know your dependency graph. They generate code that looks right locally but can't tell whether it breaks something three services downstream.
Developers Become QA
Without a way for agents to test their own work, every change requires a developer to manually verify it. The productivity gains from AI disappear at code review.
No Feedback Loop
Agents need a tight build-test-fix cycle to be effective. Without an environment to run code against real services, they generate best guesses and hope a human catches the rest.

Signadot closes the loop

Our MCP server gives coding agents direct access to sandboxes, previews, and test execution — through plain English, inside the tools your team already uses.
Natural Language, Not YAML
Developers describe the goal. The agent figures out what sandboxes to create, how to route traffic, and what tests to run. No new config formats. No Signadot-specific syntax.
Autonomous Agent Sessions
Agents spin up a sandbox, run code against real dependencies, read test results, fix failures, and iterate — without developer intervention. Long-running sessions that produce verified code, not untested drafts.
Validated Before Review
Every change is tested against the real dependency graph inside an isolated sandbox. By the time code reaches a developer, it already works.
Every coding agent. One infrastructure.
Cursor. Claude Code. Codex. Windsurf. If it supports MCP, it works with Signadot. Your team picks the tool. We provide the infrastructure.
No staging sprawl
Sandboxes run on your existing Kubernetes cluster. No duplicate environments, no extra GPUs. Agents and developers share core infrastructure while testing in complete isolation.
See it in action
Plug Signadot's MCP server into your coding agent and watch it create sandboxes, run tests, and iterate — all from a single prompt.

Built for agentic development

The infrastructure layer that takes coding agents from code generation to validated, shippable changes.

Develop

our agent writes code and immediately spins up a sandbox to test it against real dependencies. No waiting for CI. No manual environment setup.

Preview

The agent generates a shareable preview URL for every change. Developers, PMs, or QA see exactly how the code behaves end-to-end before it's merged.

Test

Automated tests run inside the sandbox after every iteration. The agent uses results to fix its own code and only surfaces when the work is done.

Review verified code, not AI drafts.

Give your coding agents infrastructure to validate their own work.
