Build a Live Incident Room App with ToolJet MCP and Jev

Payments on-call teams need a live incident room that keeps triage, commander decisions, and review metrics in one place. Build a live incident room with ToolJet MCP when you want a two-page app for card-processing incidents, and Jev, TypeSafe’s decision model, returns severity, blast radius, customer impact, page-leadership probability, and likely cause for each open record while a person decides. In this build, an agent generated the app and the result is a structured ToolJet application, data, queries, and interface together, that the team keeps running. By the end, you can reproduce the war room, review page, and commander flow from the prompt in this article.

The War room: open incidents sorted by Jev’s severity, the selected incident with its timer, metrics and Jev triage card, and the live timeline with the Slack preview.

The Review page: Jev versus commander agreement, MTTA to MTTR by severity, override rate by likely cause, and every incident from the last 7 days.

The War room page puts the open incident list on one side, the selected incident in the centre, and the live timeline plus staged Slack preview on the other side. You click a row, inspect the first three alerts, review the AI triage card, compare the suggested severity with the commander override, add a note, change status, and post updates without leaving the record. The layout keeps the command decision on the same screen as the timeline, so the commander sees current state and discussion history together. Jev returns severity, blast radius, customer impact, page-leadership probability, and likely cause, and the card shows confidence for each choice, the customer-impact score on a 1 to 5 scale, and the page-leadership probability as a percentage. The Review page summarizes agreement, overrides, MTTA, MTTR, and the last 7 days of incidents.

• Automatic triage for open incidents through the TypeSafe datasource
• Commander severity confirmation and override
• Live timeline updates and staged Slack posts
• Review metrics for agreement, MTTA, and MTTR
• Role-based write paths for commanders, engineers, and viewers

ToolJet MCP connects your coding agent to your ToolJet workspace, so the agent can create the tables, queries and components for you. Set it up with the ToolJet MCP overview and the ToolJet MCP repository. Then add the TypeSafe datasource to the workspace and name it typesafe, which is the name the build prompt refers to.

• At build time: ToolJet MCP lets the agent create the app in your workspace.
• At run time: the app calls Jev, TypeSafe’s decision model, through the typesafe datasource and shows its typed answers next to the record.

The real build took several passes, and the requirements are consolidated into one prompt that could have been used from the start. You can use the prompt in this article to reproduce the same two-page incident room in one shot.

ToolJet MCP works through the whole application, not the screen, so the incident data model, the pages, the component tree, the queries, and the wiring between them land as one structured ToolJet application. The generated app sits on a runtime that carries data connectivity, workflows, permissions, deployment, and ongoing change where supported, instead of leaving the team with a codebase to assemble and operate separately. The path stays open, so you can move from AI generation to visual editing and then to code where a case needs it.

The customer-impact card showed the wrong scale, so the number looked lower than the triage meant. Jev returned the score as a 0-based legend index, not a 0 to 1 value, and the display now adds 1 before it is shown.

The app ended up with three tables. ir_incidents stores the incident feed and cached AI triage, ir_decisions records commander severity decisions, and ir_timeline keeps the timestamped updates and staged Slack posts.

Page	Components	What they cover
War room	19	Open incidents sorted by Jev’s severity, the selected incident with Jev’s triage card, and the live timeline.
Review	8	Jev versus commander agreement, MTTA to MTTR by severity, override rate by likely cause and a 7-day table.

Metric	Result

Payments processors, fintech platforms, card issuers and acquirers, and any SaaS team running an on-call rotation can use this pattern. It fits wherever severity is argued about in a noisy chat channel and the team needs an AI first opinion, a clear commander decision and a record of how often the two agree.

Three workspace groups control what each person can do. Incident Room – Commanders (and workspace admins) can confirm or override severity, change incident status and post the Slack update. These write queries are restricted to them on the server. Incident Room – Engineers can add timeline updates only. Support and leadership in Incident Room – Viewers can open both pages and read everything, but every action control is disabled for them. AI triage runs for every viewer so the board is always current.

A Live Incident Room app usually has to pass a security review before rollout, and ToolJet supports that review with regular SOC 2 Type II audits, GDPR compliance and documented data protection controls. Reviewers can check the platform against standards they already use instead of starting from scratch.

For an incident room like this, security, legal, and auditors care about how incident notes and decisions map to review records. That is the path this section addresses for payments teams.

SOC 2 Type II and GDPR Compliance in ToolJet

• SOC 2 Type II audits: ToolJet undergoes regular SOC 2 Type II audits to validate its security, availability and confidentiality standards.
• GDPR compliance: ToolJet states that it fully complies with the General Data Protection Regulation and follows a GDPR-compliant data deletion policy, removing personal data on request or at the end of the retention period.
• Trust center: ToolJet points reviewers to trust.tooljet.com for the latest security documentation and compliance certifications.

• Encryption in transit and at rest: traffic between users and ToolJet servers uses TLS, and sensitive stored data is encrypted at rest.
• Encrypted workspace secrets: constants and secrets are encrypted before storage, and secrets resolve on the server so they never reach the browser.
• Audit logs for reviews: record user, app and data query activity with who, what, when and IP address.
• CJIS configuration guidance: criminal justice agencies get a guide to configuring a self-hosted deployment for CJIS Security Policy controls. There is no CJIS certification for platforms, so compliance remains the agency’s responsibility.

For the Live Incident Room app, this gives security and legal reviewers audited evidence plus concrete controls to check, and teams with stricter data rules can pair it with self-hosted deployment to keep data on their own infrastructure.

An incident room handles severity decisions, timeline updates, and commander notes. ToolJet covers that governance at the platform layer, so you configure it once instead of rebuilding it in every app.

• SSO and SCIM: sign in with SAML, OIDC or LDAP, and provision users automatically
• Role-based access control: scope permissions to the app, the data source, and each query
• Audit logs: track every login, edit, and approval decision for compliance review
• Air-gapped deployment: self-host on Docker or Kubernetes so your data stays in your network
• Multiplayer editing: several builders work on the same app, with versioning and Git sync
• ToolJet AI inside your own deployment: run the AI features in your tenancy rather than a shared service

You could add a notification layer with ToolJet Workflows. For example, a workflow could fire when a commander posts an override, send a Slack message to the incident channel, email leadership through Gmail, and write the decision back to ir_decisions.

This build shows a two-page incident room that keeps the on-call flow in one place: open incidents, Jev triage, commander decisions, timeline updates, and a review page for agreement and recovery metrics. The team gets a shared view of each card-processing incident, plus a record of what the commander confirmed or overrode, so response stays tied to the same data that drives the list. If you are building a live incident room with ToolJet MCP, the useful part is not the screen alone, it is the editable ToolJet application behind it, ready for the next change.
