MOST DANGEROUS TOOLS

High Risk

The most dangerous Sendbird tools

Execute · High ban_disruptive_user Banning a user triggers an external moderation action that restricts a user's access to a channel. Write · Medium create_chat_user This tool creates new data (user account and access token) in a reversible manner. Write · Medium create_group_channel Creating a group channel is a reversible write operation: the channel can be deleted or archived later. Write · Medium send_admin_message This tool creates new message data in a chat channel, which falls under the Write category (creates or modifies data reversibly).

4 of Sendbird's 5 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Sendbird

PolicyLayer is an MCP gateway — it sits between your AI agents and Sendbird, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "create_chat_user": {
    "limits": [
      {
        "counter": "create_chat_user_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "fetch_channel_history": {
    "limits": [
      {
        "counter": "fetch_channel_history_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Create a free account and register Sendbird — nothing to install.
Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about Sendbird

How do I prevent bulk modifications through Sendbird? +

The Sendbird server has 3 write tools including create_chat_user, create_group_channel, send_admin_message. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach Sendbird.

How many tools does the Sendbird MCP server expose? +

5 tools across 2 categories: Read, Write. 1 are read-only. 4 can modify, create, or delete data.

How do I enforce a policy on Sendbird? +

Register the Sendbird MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every Sendbird tool call.

Deterministic rules across all 5 Sendbird tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
