send · Claude Intercom MCP: Risk & Policy

WHAT IT DOES

What send does on Claude Intercom

AI agents use send to create or update resources in Claude Intercom — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Claude Intercom environment.

WHY IT NEEDS A POLICY

Why send needs a policy

The tool creates messages in a shared communication system, reversibly modifying state. This is not Read (it changes state), not Execute (no external code or operations triggered), not Destructive (messages can theoretically be cleared/overwritten), and not Financial.

From the tool's definition Tool description states 'Send a message to another agent or broadcast' — this creates/adds data (messages) that can be read by other agents.

Verdict

send Rate-limited

send stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about send

What does the send tool do? +

Send a message to another agent or broadcast. Use. It is categorised as a Write tool in the Claude Intercom MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on send? +

Register the Claude Intercom MCP server in PolicyLayer and add a rule for send: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Claude Intercom. Nothing to install.

What risk level is send? +

send is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit send? +

Yes. Add a rate_limit block to the send rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block send completely? +

Set action: deny in the PolicyLayer policy for send. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides send? +

send is provided by the Claude Intercom MCP server (sanztheo/claude-intercom). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
