1 check matched something in the tool definitions. No finding is not a safety guarantee. How the checks work.

Findings

Matches of fixed checks, with the text they matched.

1 warn
  • Warngenerate_launch_config

    The server marks "generate_launch_config" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

    Matched text

    annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "generate_launch_config" says "generate": a word for a change.

  • check_deployment_fit$0.01 USDC on Base mainnet: check model/configuration fit against bounded StackBench capacity evidence.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Install

Pinned to version 0.2.1. Values in angle brackets are yours to fill in.

claude mcp add --transport http stackbench https://mcp.computesage.com/mcp

Run in a terminal.

Claude Code permissions

Allow the reads, ask before a change, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__stackbench__search_evidence"
    ],
    "ask": [
      "mcp__stackbench__check_deployment_fit",
      "mcp__stackbench__predict_performance",
      "mcp__stackbench__recommend_deployment",
      "mcp__stackbench__generate_launch_config"
    ],
    "deny": []
  }
}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. It assumes the server is installed as stackbench. Review it before you use it.
