Start TDD workflow: creates branch and sets stage

Creates git branches and changes workflow

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

// WHEN AI AGENTS USE THIS TOOL

AI agents invoke start_story to trigger processes or run actions in Elixium Ai. 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.

// WHY ENFORCE A POLICY ON START_STORY

start_story 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.

// RECOMMENDED POLICY

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

// FAQ

What does the start_story tool do? +

Start TDD workflow: creates branch and sets stage. It is categorised as a Execute tool in the Elixium Ai MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on start_story? +

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

What risk level is start_story? +

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

Can I rate-limit start_story? +

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

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

start_story is provided by the Elixium Ai MCP server (@elixium.ai/mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
