Quick Start

No install needed — npx downloads and runs it automatically.

1. Add to your AI assistant

Claude Code

claude mcp add adaptive-cards-mcp -- npx adaptive-cards-mcp

GitHub Copilot (VS Code)

Add to .vscode/mcp.json:

{
  "servers": {
    "adaptive-cards-mcp": {
      "command": "npx",
      "args": ["adaptive-cards-mcp"]
    }
  }
}

Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "adaptive-cards-mcp": {
      "command": "npx",
      "args": ["adaptive-cards-mcp"]
    }
  }
}

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "adaptive-cards-mcp": {
      "command": "npx",
      "args": ["adaptive-cards-mcp"]
    }
  }
}

Microsoft 365 Copilot / Copilot Studio (HTTP/SSE)

TRANSPORT=sse PORT=3001 npx adaptive-cards-mcp

# With auth enabled
TRANSPORT=sse MCP_API_KEY=your-secret npx adaptive-cards-mcp

1. Open Copilot Studio → your agent → Tools → Add a tool → New tool → Model Context Protocol
2. Enter your MCP server URL (e.g., https://your-server.azurewebsites.net/sse)
3. Select the tools to expose

OpenAI ChatGPT

1. Enable Developer mode in ChatGPT settings
2. Go to Settings → Connectors → Create
3. Enter your MCP server HTTPS URL

2. Start using it

Just ask your AI assistant in natural language:

> Create an expense approval card for Teams

> Convert this JSON data into an Adaptive Card table

> Validate this card and fix accessibility issues

> Make this card work on Outlook (v1.4)

The AI picks the right tools, generates a valid card, validates it, and returns production-ready JSON you can paste directly into the Adaptive Cards Designer to preview.

Usage

Natural language (recommended)

Describe what you need — the AI figures out which tools to call:

Approvals and workflows:

> Create an expense approval card for Teams with requester photo, amount,
  category, line items, and approve/reject/comment buttons

> Build a time-off request card — employee name, dates, remaining PTO balance,
  manager approval with optional rejection reason

Notifications and alerts:

> Create a CI/CD deployment notification: service name, environment, build number,
  commit SHA, deploy status with rollback button

> Generate a PagerDuty-style incident alert card — severity P1, affected service,
  start time, on-call engineer, acknowledge/escalate actions

Data and reports:

> Here's our Q1 sales data, turn it into a card:
  [{"region":"APAC","revenue":1250000,"growth":"12%"},
   {"region":"EMEA","revenue":980000,"growth":"8%"},
   {"region":"Americas","revenue":2100000,"growth":"15%"}]

> Convert this CSV to a card:
  Employee,Department,Start Date,Status
  Jane Kim,Engineering,2026-01-15,Active
  Bob Lee,Design,2026-02-01,Active
  Carol Wu,PM,2026-03-10,Onboarding

Forms and input:

> Create an employee onboarding checklist — new hire name, start date,
  assigned buddy, IT setup tasks with checkboxes, and a submit button

> Build a customer feedback survey card with a 1-5 star rating,
  comment field, and NPS score dropdown

Profiles and status:

> Create a team member profile card with photo, name, title, department,
  skills tags, and contact buttons for email/chat/calendar

> Build a service health dashboard card showing 5 microservices
  with status indicators (healthy/degraded/down) and last check time

Cross-host and versioning:

> This card works in Teams but breaks in Outlook — fix it
> Make this card work on Webex (v1.3 only, no Table, no Action.Execute)
> Downgrade this v1.6 card to v1.4 for Viva Connections

Validation and optimization:

> Validate this card and tell me what's wrong — I'm getting render errors
> Make this card accessible — it needs to work with screen readers
> This card is too complex, optimize it for performance and compact layout

| What you say | What the AI calls | |-------------|-------------------| | "Create a leave approval card for Teams" | generate_and_validate → optimized card with Approve/Reject actions | | "Here's my API response, make it a card" | data_to_card → auto-picks Table/FactSet/List based on data shape | | "Is this card valid for Outlook?" | validate_card → schema errors, accessibility score, host compatibility | | "Make this card accessible" | optimize_card → adds wrap, altText, speak, heading styles | | "Convert this card to a reusable template" | template_card → static values become ${expression} bindings | | "This card needs to work on v1.3" | transform_card → downgrades, removes unsupported features | | "What layout should I use for a dashboard?" | suggest_layout → pattern recommendation with rationale |

Slash commands (MCP prompts)

For guided, multi-step workflows, use the built-in prompts directly:

Create a card:

> /adaptive-cards-mcp:create-adaptive-card
  description: "Expense approval with requester photo, line items table, total amount,
                and approve/reject buttons with comment field"
  host: teams
  intent: approval

Runs: generate → validate → optimize → host config

> /adaptive-cards-mcp:create-adaptive-card
  description: "CI/CD deployment notification with service name, environment,
                build number, status badge, and rollback action"
  host: teams
  intent: notification

> /adaptive-cards-mcp:create-adaptive-card
  description: "Employee profile card with photo, name, title, department,
                contact info, and skills tags"
  host: outlook
  intent: profile

Convert data to a card:

> /adaptive-cards-mcp:convert-data-to-card
  data: [
    { "task": "Review PR #482", "assignee": "Jane", "due": "2026-03-21", "status": "pending" },
    { "task": "Deploy hotfix v2.1.3", "assignee": "Bob", "due": "2026-03-19", "status": "in-progress" },
    { "task": "Update API docs", "assignee": "Carol", "due": "2026-03-22", "status": "done" }
  ]
  title: "Sprint Tasks"
  presentation: table

> /adaptive-cards-mcp:convert-data-to-card
  data: { "service": "api-gateway", "cpu": "92%", "memory": "78%", "requests": "12.4k/min",
          "p99_latency": "245ms", "error_rate": "0.3%", "uptime": "99.97%" }
  title: "Service Health — api-gateway"
  presentation: facts

Runs: analyze data → pick best layout → validate output

Review an existing card:

> /adaptive-cards-mcp:review-adaptive-card
  card: { "type": "AdaptiveCard", "version": "1.6", "body": [...your card...] }
  host: outlook

Runs: validate schema + accessibility → auto-fix issues → summary report

npm library (programmatic)

For use in your own code (bots, APIs, CI pipelines), install the package:

npm install adaptive-cards-mcp

import { generateCard, validateCardFull, dataToCard, optimizeCard } from 'adaptive-cards-mcp';

const result = await generateCard({
  content: "Create a flight status card",
  host: "teams",
  intent: "display"
});

console.log(result.card);       // Adaptive Card JSON
console.log(result.cardId);     // Reference ID for subsequent calls
console.log(result.validation); // Schema + accessibility + host compat

See the [Library API reference](packages/core/README.md#library-usage) for full details.

What you get back

Card-producing tools return two clean blocks — card JSON you can copy, and a metadata summary:

````

{
  "type": "AdaptiveCard",
  "version": "1.6",
  "body": [ ... ],
  "actions": [ ... ]
}

Telemetry & Privacy

Telemetry is opt-in and disabled by default. When enabled, the server collects anonymous usage metrics and sends aggregated data to PostHog to help improve the project.

How to enable:

• VS Code extension: A one-time consent prompt appears on first install. You can

change it anytime in Settings → Adaptive Cards → Telemetry.

• CLI / MCP server: Set MCP_TELEMETRY=true in your environment, or edit

~/.adaptive-cards-mcp/config.json and set "telemetry": true.

What is sent: Tool names, call counts, durations, error rates, platform (OS), Node version, package version, transport type.

What is never sent: Card content, user prompts, data payloads, IP addresses, file paths, environment variables.

A random session ID is generated each time the server starts — no persistent identifier is stored across sessions.

To disable: Set MCP_TELEMETRY=false or leave unconfigured (default is off).
