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

@sprintra/mcp Execute

AI agents invoke work_sessions to trigger processes or run actions in Sprintra. 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.

work_sessions 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 work_sessions tool do? +

Manage coding work sessions, activity feed, and traces. Methods: list, start, end, get_active, generate_claude_md, list_activity, list_traces, delta (what changed since last session), end_with_digest (VP-1219: agent self-write of rich session_digest with status=complete — covers what_was_discussed, key_decisions, open_questions, user_pushback, pending_asks, frustration_signals, links_to_artifacts; call before pause/Ctrl+C/major break per CLAUDE.md Rule 5b). It is categorised as a Execute tool in the Sprintra MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on work_sessions? +

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

What risk level is work_sessions? +

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

Can I rate-limit work_sessions? +

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

Set action: deny in the Intercept policy for work_sessions. 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 work_sessions? +

work_sessions is provided by the Sprintra MCP server (@sprintra/mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
