The tool your agent trusted on Monday can change on Tuesday - silently. mcpindex holds the call before your agent acts on the change.

The in-path trust gate for agent tool calls. It pins each MCP toolโ€™s contract and HOLDs a call when the contract silently changes - before your agent acts.

mcpindex features and specs

  • Install once, rides your agent
    One config-wire in Claude Desktop, Claude Code, Cursor, Gemini CLI, Cline, or Zed. The gate sits in your agentโ€™s MCP session. No credentials; the contract-diff runs locally and the default build egresses nothing. The optional cloud tier-1 lookup, held off by default, sends only a contract hash-never tokens or call data.
  • Pins each tool on first sight
    On first sight, the gate records the toolโ€™s contract-name, params, constraints, annotations, schemas-and persists it across restarts. TOFU: the baseline is what you saw.
  • HOLDs the call when the contract changes
    On every later call, the gate diffs the live contract against your pin. Silent required-param adds, narrowed constraints, or destructive flips HOLD the call and name the ChangeKind.
  • You review, re-pin, or validate
    A held call is a decision: read the diff, re-pin the new contract, or send it back. Benign added-optional proceeds silently. The verdict is โ€œthis changed,โ€ never โ€œthis is unsafe.โ€

Analysis of Sane Stack

Overall verdict

  • I don't have verified, reliable information about Sane Stack (sanestack.com) to make an informed assessment. I cannot confirm details about its features, pricing, quality, or user experiences, and I don't want to fabricate claims about a product I have no confirmed data on.

Why this product is good

  • I do not have specific, verified information about this product in my training data
  • Making claims about an unfamiliar product could provide you with inaccurate or misleading information
  • The domain name suggests it may be a tech stack, boilerplate, or development tool, but I cannot confirm its actual purpose or quality

Recommended for

  • I'd recommend checking the official website directly for accurate details on features and pricing
  • Look for independent reviews on platforms like G2, Trustpilot, Reddit, or Hacker News for real user experiences
  • Consider reaching out to their support team with specific questions about your use case
  • Check if they offer a free trial or demo to evaluate firsthand before committing
