Execute bash commands in a REMOTE sandbox for file operations, data processing, and system tasks. Essential for handling large tool responses saved to remote files. PRIMARY USE CASES: - Process large tool responses saved by RUBE_MULTI_EXECUTE_TOOL to remote sandbox - File system operations, ...
Accepts freeform code/query input (command)
Part of the Rube MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents invoke RUBE_REMOTE_BASH_TOOL to trigger processes or run actions in Rube. 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.
RUBE_REMOTE_BASH_TOOL 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.

RUBE_REMOTE_BASH_TOOL is one of the high-risk operations in Rube. For the full severity-focused view — only the high-risk tools with their recommended policies — see the breakdown for this server, or browse all high-risk tools across every MCP server.
Execute bash commands in a REMOTE sandbox for file operations, data processing, and system tasks. Essential for handling large tool responses saved to remote files. PRIMARY USE CASES: - Process large tool responses saved by RUBE_MULTI_EXECUTE_TOOL to remote sandbox - File system operations, extract specific information from JSON with shell tools like jq, awk, sed, grep, etc. - Commands run from /home/user directory by default . It is categorised as a Execute tool in the Rube MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Add a rule in your Intercept YAML policy under the tools section for RUBE_REMOTE_BASH_TOOL. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Rube MCP server.
RUBE_REMOTE_BASH_TOOL is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the RUBE_REMOTE_BASH_TOOL 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.
Set action: deny in the Intercept policy for RUBE_REMOTE_BASH_TOOL. 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.
RUBE_REMOTE_BASH_TOOL is provided by the Rube MCP server (Composio/Rube). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
