devbox_context_compile

Compile a context bundle from a set of artifacts, applying layering (base, project, session, ephemeral), deduplication, and budget trimming. Returns a ready-to-inject bundle with provenance metadata.

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

// WHEN AI AGENTS USE THIS TOOL

AI agents invoke devbox_context_compile to trigger processes or run actions in Devbox. 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 DEVBOX_CONTEXT_COMPILE

devbox_context_compile 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.

devbox.yaml

tools:
  devbox_context_compile:
    rules:
      - action: allow
        rate_limit:
          max: 10
          window: 60
        validate:
          required_args: true

What does the devbox_context_compile tool do? +

Compile a context bundle from a set of artifacts, applying layering (base, project, session, ephemeral), deduplication, and budget trimming. Returns a ready-to-inject bundle with provenance metadata.. It is categorised as a Execute tool in the Devbox MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on devbox_context_compile? +

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

What risk level is devbox_context_compile? +

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

Can I rate-limit devbox_context_compile? +

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

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

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