Trigger a full inbox sync to discover new threads and update existing ones from the email provider. Like hitting refresh in an email client. Use this when you need to find recently arrived emails that aren't yet in TextForge. Requires 'threads:sync' permission.
Part of the TextForge MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents invoke sync_inbox to trigger processes or run actions in TextForge. 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.
sync_inbox 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.

Trigger a full inbox sync to discover new threads and update existing ones from the email provider. Like hitting refresh in an email client. Use this when you need to find recently arrived emails that aren't yet in TextForge. Requires 'threads:sync' permission.. It is categorised as a Execute tool in the TextForge 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 sync_inbox. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the TextForge MCP server.
sync_inbox 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 sync_inbox 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 sync_inbox. 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.
sync_inbox is provided by the TextForge MCP server (textforge/textforge). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
