What sam_build does on Amazon ElastiCache Memcached MCP Server

AI agents invoke sam_build to trigger actions in Amazon ElastiCache Memcached MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

High Risk

Why sam_build needs a policy

SAM build executes a build process that compiles code, resolves dependencies, and generates artifacts. While not immediately destructive, it runs external operations whose effects depend on the application code being built. The lack of description lowers confidence, but the tool name strongly indicates code compilation/execution.

From the tool's definition Tool named 'sam_build' with no description. 'sam_build' refers to AWS SAM (Serverless Application Model) build command, which compiles and prepares serverless code for deployment.

Documented attack patterns abuse exactly the kind of access sam_build gives an agent:

How to control sam_build

PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon ElastiCache Memcached MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for sam_build:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "sam_build": {
      "limits": [
        {
          "counter": "sam_build_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

sam_build stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Amazon ElastiCache Memcached MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Questions about sam_build

What does the sam_build tool do? +

sam_build. It is categorised as a Execute tool in the Amazon ElastiCache Memcached MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on sam_build? +

Register the Amazon ElastiCache Memcached MCP Server MCP server in PolicyLayer and add a rule for sam_build: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Amazon ElastiCache Memcached MCP Server. Nothing to install.

What risk level is sam_build? +

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

Can I rate-limit sam_build? +

Yes. Add a rate_limit block to the sam_build rule in your PolicyLayer 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 sam_build completely? +

Set action: deny in the PolicyLayer policy for sam_build. 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 sam_build? +

sam_build is provided by the Amazon ElastiCache Memcached MCP Server MCP server (awslabs.memcached-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Amazon ElastiCache Memcached MCP Server tool call.
