Automate API testing with the Assertible MCP Server

`run_service_tests` triggers your remote API verification suites directly from VS Code Copilot. Your engineering team can run tests on shared branches with a simple chat command. If a team member breaks a route, Copilot uses `run_specific_test` to isolate the failure. This keeps your CI pipeline green and reduces debugging time.

Manage deployments and track status badges

`create_deployment` registers your team's code pushes directly to Assertible from VS Code Copilot. This action kicks off your automated test suites immediately after deployment. You can monitor the health of these deployments using `get_service_status_badge` via MCP server integrations. Copilot displays the live markdown badge in your team chat.

Sync specifications and validate schemas in VS Code Copilot

`sync_specification` keeps your OpenAPI or Swagger files synchronized with Assertible. Your agent reads your workspace files and updates your test definitions. For payload validation, `validate_json` checks your API responses against Draft 4 schemas. This ensures your response structures match your specifications.
