How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security74
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability42
- 0% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Fail
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 525 tokens (~87/item across 6 items; 5 tools + 1 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management3
- Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
create_sound Create a sound ~183
Build a notification sound from your own layer design and get an editor link for it. The link opens the sound in the editor, where the user plays, tweaks and downloads it. Returns the link, the stored sound and warnings for any value that was out of range, rounded or ignored. Read get_sound_guide first.
| Name | Type | Req | Description |
|---|---|---|---|
| duration | number | – | Note length. How long each note is held, shared by every layer and every repeat. Unit: s. Range 0.003 to 5, step 0.001, default 0.1. |
| effect | object | – | One effect over the whole sound. |
| layers | array | yes | Layers play together, each from its own Start after. Leave out any field at its default. Up to 16 layers. |
| name | string | – | Name. Sound name, up to 32 characters. |
No output schema declared.
No examples provided.
get_library_sound Get a built-in sound ~70
Get the full design of a built-in sound and its editor link, to use as a starting point for create_sound.
| Name | Type | Req | Description |
|---|---|---|---|
| group | string | – | Group to look in, when a name is in more than one. |
| name | string | yes | Sound name, e.g. "Tri-Tone". |
No output schema declared.
No examples provided.
get_sound_guide Sound design guide ~39
How sounds are built: layers, envelope, pitch, timing, noise, levels and effects, with example designs. Read it once before designing.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_library_sounds List built-in sounds ~81
List the built-in sounds by group, or search them by name. Without arguments it lists every group with its sound names. Use a close built-in sound as a starting point.
| Name | Type | Req | Description |
|---|---|---|---|
| group | string | – | Only this group, with each sound described. |
| query | string | – | Search sound names, e.g. "bell" or "coin". |
No output schema declared.
No examples provided.
read_sound Read a share link ~55
Turn a share link (or the code after #s=) back into the sound design, to change it and call create_sound again.
| Name | Type | Req | Description |
|---|---|---|---|
| link | string | yes | A share link, "#s=..." or the bare code. |
No output schema declared.
No examples provided.
How do I install the Notify Sound MCP server?
Notify Sound is a hosted endpoint at https://notifysound.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Is the Notify Sound MCP server safe to use?
Notify Sound scores 66 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Notify Sound MCP server expose?
Notify Sound exposes 5 tools: create_sound, read_sound, list_library_sounds, get_library_sound, get_sound_guide. Their descriptions and schemas cost roughly 428 tokens of context every time the server is loaded.
Does the Notify Sound MCP server require authentication?
No. We connected to Notify Sound without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Notify Sound MCP server still maintained?
Notify Sound is still listed as active in the MCP registry. We last reached this channel on 23 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
