NotifyHub — Unified Notification MCP Server

io.github.GabrielBBaldez/notify-hubv1.1.0Other

Send notifications across 23 channels with 36 AI-ready tools. One API, zero boilerplate.

In-path gate · all MCP tools

Using NotifyHub — Unified Notification MCP Server in Claude, Cursor, Gemini CLI, Cline, or Zed?

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).

Install the mcpindex gate (one command)

Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

Limits of this verdict

- Semantic screen only - the deterministic conformance probe has not run on this server
- Confidence is reported but not yet calibrated (v1)
- Screen reads the tool description, not the live behavior
- advisory
- registry description only no input schema
- screen model 8b

Semantic screen: an LLM judge reads the tool description for hidden instructions (status PARTIAL). A pass means the description is not lying, not that the tool is safe: a high-capability tool with an honest description still warrants caution. The deterministic conformance probe has not been run on this server yet, so the screen here is semantic-only. Posture: advisory. Confidences are reported but not yet calibrated (calibrated=false at v1). Full verdict history is not shown on this page.

That verdict was true at screening time (snapshot 2026-07-31).

Contracts can change after screening, with no version bump. The gate pins NotifyHub — Unified Notification MCP Server’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

Provenance

Each verdict is bound to a hash of the exact description it judged, so a re-crawl that changes the text produces a new record rather than silently inheriting this one. Verdict history is hash-chained and anchored to Bitcoin via OpenTimestamps (latest confirmed at block 960,209). Verify it yourself.
