WHAT IT DOES

What update_sequence does on Sequenzy Mcp

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

RISK

Why update_sequence is rated Medium

This tool modifies existing data (sequence settings and steps) but does not delete or irreversibly destroy data. The changes are reversible through subsequent updates. While it affects email marketing campaigns, it is fundamentally a data modification operation (Write category) rather than Destructive.

From the tool's definition Tool description states it 'Update[s] an existing sequence: both its settings and its steps' including 'name, description, labels, trigger', 'enrollmentMode', 'enrollmentPaused', 'stopCondition', 'sendingWindow', 'bccEmails', and 'sender/reply identity'.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs update_sequence safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Sequenzy Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For update_sequence, this is the rule to start with:

update_sequence Rate-limited

update_sequence 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 update_sequence

What does the update_sequence tool do? +

Update an existing sequence: both its settings and its steps. Sequence-level settings live directly on this tool - name, description, labels, trigger (with its trigger-specific field), enrollmentMode plus enrollmentFieldPath, enrollmentPaused, userCancellable, stopCondition, sendingWindow, bccEmails, and the sender/reply identity. This is the only way to change enrollmentMode after create_sequence, so use it to move a tag- or event-triggered sequence off the default. It is categorised as a Write tool in the Sequenzy Mcp MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on update_sequence? +

Register the Sequenzy MCP server in PolicyLayer and add a rule for update_sequence: 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 Sequenzy Mcp. Nothing to install.

What risk level is update_sequence? +

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

Can I rate-limit update_sequence? +

Yes. Add a rate_limit block to the update_sequence 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 update_sequence completely? +

Set action: deny in the PolicyLayer policy for update_sequence. 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 update_sequence? +

update_sequence is provided by the Sequenzy MCP server (Sequenzy/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
