# TaScan MCP Server

AI agent integration for [TaScan](https://tascan.io) — the closed-loop autonomous operations protocol. Manage projects, events, tasks, workers, QR codes, templates, completion reports, and AI-powered issue resolution through Claude, GitHub Copilot, or any MCP-compatible AI client.

**Task. Scan. Done.**

## What is TaScan?

TaScan is a zero-download task assignment and verification platform for physical-world work. Workers scan a QR code, complete tasks with photo verification, and managers get real-time completion reports — no app download, no login, no training required.

When something breaks, AI analyzes the issue, generates fix instructions, and dispatches them to the right worker — closing the loop autonomously in under 10 seconds.

Industries: live events, construction, hospitality, warehousing, property management, healthcare, aviation, FEMA disaster response, and more.

## Quickest Start: Claude.ai / Claude Mobile

No install required. Add TaScan as a custom connector in Claude:

1. **Settings > Connectors > Add custom connector**
2. Enter: `https://app.tascan.io/mcp`
3. First time you use a tool, sign in with your TaScan email and password

That's it. Works on claude.ai and Claude mobile. Same sign-in experience as GitHub, Netlify, and Supabase connectors.

## Installation (Claude Desktop / Claude Code)

```bash
npm install tascan-mcp
```

Or run directly with npx:

```bash
npx tascan-mcp
```

## Configuration

### Environment Variables

| Variable | Required | Description |
|----------|----------|-------------|
| `TASCAN_API_KEY` | Yes | Your TaScan API key (generate in Admin Portal > Team > API Keys) |
| `TASCAN_API_URL` | No | API base URL (default: `https://app.tascan.io/api/v1`) |

### Claude Desktop

Add to your Claude Desktop config file (`claude_desktop_config.json`):

```json
{
  "mcpServers": {
    "tascan": {
      "command": "npx",
      "args": ["-y", "tascan-mcp"],
      "env": {
        "TASCAN_API_KEY": "your-api-key-here"
      }
    }
  }
}
```

### Claude Code

```bash
claude mcp add tascan -- npx -y tascan-mcp
```

Then set your API key in the environment.

### Remote (claude.ai / Claude Mobile)

TaScan MCP is also available as a remote server — no install, no API key needed:

```
https://app.tascan.io/mcp
```

Add as a custom connector in Claude (Settings > Connectors). When you first use a tool, you'll be redirected to sign in with your TaScan email and password — just like connecting GitHub or Netlify. OAuth 2.0 with PKCE handles everything automatically.

## Usage Examples

### Example 1: Set up a construction site inspection

```
User: Create a construction project for the Downtown Tower site and set up a daily safety inspection with tasks for PPE check, fall protection, scaffolding inspection, and fire extinguisher check. Make all tasks safety checkpoints that require photos.

Claude will:
1. Call tascan_create_project with name "Downtown Tower" and location "123 Main St"
2. Call tascan_create_event with name "Daily Safety Inspection"
3. Call tascan_add_tasks with 4 safety checkpoint tasks requiring photos
4. Call tascan_generate_qr to create a scannable QR code for the foreman
```

### Example 2: AI-powered autonomous issue resolution

```
User: Check if there are any open issues on the Marriott load-in and have TaScan fix them automatically.

Claude will:
1. Call tascan_list_issues to find open issues
2. Call tascan_auto_resolve for each issue — AI analyzes root cause, generates fix tasks, and dispatches instructions to the nearest qualified worker via SMS
3. Report back with resolution status and confidence scores
```

### Example 3: Use templates to quickly deploy an event

```
User: We have a warehouse receiving shipment coming in tomorrow. Set up the standard receiving checklist.

Claude will:
1. Call tascan_list_templates with category "logistics" to find available templates
2. Call tascan_create_project for the warehouse
3. Call tascan_create_event for the receiving session
4. Call tascan_apply_template with the "warehouse-receiving" template slug
5. Call tascan_generate_qr for the receiving dock crew
```

### Example 4: Analyze and triage field issues

```
User: We have 5 open issues on the concert setup. Analyze them all and tell me which ones are most urgent.

Claude will:
1. Call tascan_list_issues to get all open issues
2. Call tascan_analyze_issue for each one — AI classifies severity, root cause probability, and urgency score
3. Rank by urgency and recommend which to auto-resolve vs which need human attention
```

## Task Types

Tasks support multiple response types:

| Type | Description |
|------|-------------|
| `checkbox` | Simple done/not-done (default) |
| `photo` | Requires photo upload to complete |
| `text` | Free-text response |
| `number` | Numeric response |
| `date` | Date selection |
| `choice` | Multiple choice selection |

Tasks can also be flagged as:
- **Safety checkpoints** (`is_safety_checkpoint: true`) — highlighted in red, cannot be skipped
- **Photo required** (`requires_photo: true`) — worker must attach a photo to complete

## Getting an API Key

1. Log in to the [TaScan Admin Portal](https://app.tascan.io)
2. Navigate to **Team** in the sidebar
3. Scroll to **API Keys**
4. Click **Generate API Key**
5. Copy the key (it's only shown once)
6. Set it as `TASCAN_API_KEY` in your environment

API keys are scoped to your organization and support rate limiting (60 requests/minute).

## Troubleshooting

**"Connection failed" or OAuth redirect issues**
- Verify you're using the correct URL: `https://app.tascan.io/mcp`
- Clear your browser cache and try reconnecting
- If using Claude Desktop, restart the app after adding the connector

**"Unauthorized" or 401 errors (local npm install)**
- Regenerate your API key in Admin Portal > Team > API Keys
- Confirm `TASCAN_API_KEY` is set in your environment (not just in the config file)
- Keys are organization-scoped — make sure you're using a key from the correct org

**Tools not showing up in Claude**
- Disconnect and reconnect the TaScan connector
- For Claude Code: run `claude mcp list` to verify the server is registered
- Check that your TaScan account has an active organization (free tier is fine)

**"Rate limited" errors**
- Default limit is 60 requests/minute per API key
- Pro and Business tiers have higher limits
- Batch operations (like `tascan_add_tasks`) are more efficient than individual calls

**Task completions not appearing**
- Workers must submit via the task link (QR scan or direct URL)
- Photo-required tasks won't show as complete until the photo uploads
- Check the event's response mode (single vs. multi-response)

**Photo evidence links**
- `photo_url` is the raw storage object path (stable, never changes). `photo_signed_url` is a fetchable HTTPS link that expires after ~1 hour (server default `TASCAN_PHOTO_URL_TTL=3600`). Re-run the read tool for a fresh link; never store the signed URL.
- `photo_signed_url: null` with a non-null `photo_url` means signing was unavailable at read time (storage hiccup). The read still succeeds — retry for the link.

## Changelog

### v3.12.0 — 2026-09-12
- `tascan_send_task_email` and `tascan_assess_condition` now send the caller's API key (the TaScan functions behind them require it after the S99 security sweep). No tool additions — still 69 tools.

### v3.11.0 — 2026-09-11
- **Signed photo URLs in every completion payload.** Photo evidence was invisible to AI agents: `photo_url` was a bare private-bucket path with no host or token. Every read path that returns a completion now also returns `photo_signed_url` (short-lived, default 1h, tunable via `TASCAN_PHOTO_URL_TTL`), `null` when there is no photo. Covered: `tascan_get_task` (task + subtask completions), `tascan_get_report` (new per-task `photos[]` when `include_responses` is true, replacing the bare `[+photo]` marker), `tascan_list_subtasks`, `tascan_query_responses`, `tascan_list_issues` / issue analysis (issue + injury photos), `tascan_zone_compliance` (PPE checkpoint photos), `tascan_condition_history` (assessment + baseline photos).
- One batched storage signing call per response (a 40-task list fires one request, not 40). Signing failures log and degrade to `photo_signed_url: null` with the raw path intact; the tool call never fails.
- Single shared signing helper on the server (`photo-sign-lib`) now backs the API, the photo proxy used by the Completion / Client / Project / Evidence Pack reports, and every AI vision fetcher, so URL construction cannot drift again.
- Remote endpoint `serverInfo.version` now reads from this package instead of a stale hardcoded string.

### v3.10.0 — 2026-09-03
- 69 tools: invoices, P2P worker payments, hazard zones with AI-verified PPE checkpoints, full RLS lockdown, agent claims.
