run_sequence

Execute a multi-step browser automation sequence. Navigate pages, interact with elements (click, fill, select), and capture multiple screenshots/PDFs in a single browser session. Each output counts as 1 API request.

Accepts URL/endpoint input (steps[].url); Accepts freeform code/query input (steps[].script); High parameter count (41 properties); Single-target operation

Part of the Pagebolt MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

pagebolt-mcp Execute Risk 4/5

AI agents invoke run_sequence to trigger processes or run actions in Pagebolt. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.

run_sequence can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.

Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

What does the run_sequence tool do? +

Execute a multi-step browser automation sequence. Navigate pages, interact with elements (click, fill, select), and capture multiple screenshots/PDFs in a single browser session. Each output counts as 1 API request.. It is categorised as a Execute tool in the Pagebolt MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on run_sequence? +

Add a rule in your Intercept YAML policy under the tools section for run_sequence. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Pagebolt MCP server.

What risk level is run_sequence? +

run_sequence is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit run_sequence? +

Yes. Add a rate_limit block to the run_sequence rule in your Intercept 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 run_sequence completely? +

Set action: deny in the Intercept policy for run_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 run_sequence? +

run_sequence is provided by the Pagebolt MCP server (pagebolt-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
