telebiz-mcp

MCP integration for Telegram via telebiz-tt browser client.

Quick Rules (read this first)

Rate limits are strict: max 20 calls/request, 30 calls/min, 500ms between calls, heavy ops 1s.
For adding many chats to folders: do NOT use batchAddToFolder with multiple chatIds (known bug). Loop addChatToFolder sequentially.
For CRM linking: linkEntityToChat is unstable in our tests. We observed company failing with Validation error, and at one point organization succeeding — but later organization also failed. Treat linkEntityToChat as unreliable until upstream clarifies schema/feature flags.
Prefer reversible operations and clean up test artifacts (folders, groups) immediately.

Quick Setup

Prerequisites

Node.js 18+
Telegram account

1. Install telebiz-mcp

npm install -g @telebiz/telebiz-mcp

2. Open Telebiz in browser

Go to https://telebiz.io and login with your Telegram account.

3. Start the HTTP server

cd ~/clawd/skills/telebiz-mcp
./start-http.sh

This starts a persistent server that:

Runs telebiz-mcp internally
Keeps browser connection alive
Exposes HTTP API on port 9718

4. Enable MCP in Telebiz

In telebiz.io: Settings → Agent → Local MCP

The status should show "Connected" once the server is running.

4. Verify connection

# Quick health check
cd ~/clawd/skills/telebiz-mcp
npm run health

# Should show:
# 📱 Telebiz MCP Status
# ────────────────────
# Relay: ✅ Running
# Executor: ✅ Connected
# Tools: 31 available

5. Test via mcporter

cd ~/clawd
mcporter call telebiz.listChats limit:5

Health Monitoring

Manual Check

# Check status
npm run health

# JSON output for automation
node dist/health.js --json

Monitor Script

The monitor tracks state changes and can be used with cron:

# Check and alert on changes
npm run monitor

# Quiet mode - only output on state change
node dist/monitor.js --quiet

# JSON output
node dist/monitor.js --json

Exit codes:

0 = Healthy (relay up, executor connected)
1 = Degraded (relay up, executor disconnected)
2 = Down (relay not running)
3 = State changed (for alerting)

Cron Integration

Add to crontab for periodic monitoring:

# Check every 5 minutes, alert on changes
*/5 * * * * cd ~/clawd/skills/telebiz-mcp && node dist/monitor.js --quiet >> /var/log/telebiz-monitor.log 2>&1

Heartbeat Integration

Add to HEARTBEAT.md for Clawdbot monitoring:

### Telebiz MCP (every 2h)
- [ ] Run: `cd ~/clawd/skills/telebiz-mcp && npm run health`
- [ ] If degraded/down: Alert Albert via Telegram

Rate Limiting

The browser enforces rate limits to prevent Telegram flood protection:

Max calls per request: 20
Max calls per minute: 30
Min delay between calls: 500ms
Delay for heavy operations (send/forward/delete): 1s

(These values come from the Telebiz UI and are the effective limits we observed in practice.)

Known Issues / Workarounds (Feb 2026)

`batchAddToFolder` fails for multiple chatIds

Observed behavior:

batchAddToFolder(folderId, chatIds=[one]) works (or reports alreadyIncluded)
batchAddToFolder(folderId, chatIds=[two or more]) fails with: "Error: Failed to update folder"
Repro confirmed for both:
- Auto + another group
- Auto + a private chat

Workaround: loop sequentially:

addChatToFolder(chatId=A, folderIds=[folderId])
addChatToFolder(chatId=B, folderIds=[folderId])

`linkEntityToChat` is unstable / schema mismatch

Observed behavior (Feb 2026):

linkEntityToChat returns "Validation error" for entityType=deal, contact, and company.
In one run, using entityType="organization" successfully linked a HubSpot company to a chat — but later organization also returned "Validation error".

Implication: this tool is either behind a feature flag, has changing server-side validation, or the published schema/enums don’t match what the backend expects.

Workaround:

Prefer linking via createContact/createDeal/createCompany (these link to the chat at creation time).
Use associateEntities to connect deal↔company/contact.
Don’t depend on linkEntityToChat until upstream provides a stable contract + better error messages.

Troubleshooting

Relay not starting

# Check if port is in use
ss -tlnp | grep 9716

# Kill existing process
pkill -f "relay.js"

# Start fresh
./start-relay.sh

Browser not connecting

Verify relay is running: npm run health
Check browser console (F12) for WebSocket errors
Ensure MCP is enabled in Settings → Agent → Enable MCP
Try refreshing the telebiz-tt page

"Executor not connected" error

The browser tab with telebiz-tt must be:

Open and visible (not suspended)
Logged into Telegram
MCP enabled in settings

Rate limit errors

Reduce batch sizes
Add delays between operations
Be more specific in filters to reduce API calls

Session expired

If Telegram session expires:

Refresh the telebiz-tt browser page
Re-login if prompted
Re-enable MCP in settings

Configuration

Environment Variables

| Variable | Default | Description | |----------|---------|-------------| | TELEBIZ_PORT | 9716 | Relay WebSocket port | | TELEBIZ_RELAY_URL | ws://localhost:9716 | Relay URL for MCP server | | TELEBIZ_STATE_FILE | ~/.telebiz-mcp-state.json | Monitor state file |

mcporter Config

Located at ~/clawd/config/mcporter.json:

{
  "mcpServers": {

      "url": "http://localhost:9718/mcp"
    }
  }
}

Note: Use the HTTP URL (not stdio) to avoid spawning conflicts.

Security Notes

The browser holds your Telegram session - keep it secure
Don't expose the relay port (9716) to the internet
Review tool calls before executing destructive operations
Rate limits help prevent accidental spam
