Available components
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 Security46
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (edit_session). See how to fix → View diagnostics → Fail
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- 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 Usability81
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 850 tokens (~121/item across 7 items; 7 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
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
- All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
How do I install the Keyboardia MCP server?
Keyboardia is a hosted endpoint at https://keyboardia.dev/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.

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.
- 30 Aug 26 0
- Stability: 0.97 → pass security
- 29 Aug 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 93 to 97. That category is still filling its 30-day observation window: 28 days of observed history at the previous scan, 29 at this one. The score rises as the window fills, whether or not the server changes.

No change was recorded against any check on this day. Stability & Change Management went from 87 to 90. That category is still filling its 30-day observation window: 26 days of observed history at the previous scan, 27 at this one. The score rises as the window fills, whether or not the server changes.

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 →
analyze_session Analyze Keyboardia session ~105
Describe what is happening musically in a session — rhythm, pitch content, inferred key, and chords — without changing anything. Use this to explain music rather than to edit it. Results come from the same music-theory module the browser's Key Assistant and Chromatic Grid use, and report where the analysis is uncertain instead of guessing.
| Name | Type | Req | Description |
|---|---|---|---|
| session_id | string | yes | The UUID after /s/ in a Keyboardia share URL. Pass only the UUID, not the full URL. |
No output schema declared.
No examples provided.
create_session Create Keyboardia session ~127
Create a new editable Keyboardia session with the normal defaults and return its shareable URL. The session starts with no tracks; use edit_session to add them. Pass the same idempotency_key when retrying so an uncertain attempt cannot leave duplicate sessions behind.
| Name | Type | Req | Description |
|---|---|---|---|
| idempotency_key | string | yes | A UUID you generate for this creation attempt. Reusing it returns the session the first attempt created instead of making another one. |
| name | string | – | Optional display name for the new session. |
| tempo | number | – | Starting tempo in BPM. Defaults to Keyboardia's own default. |
No output schema declared.
No examples provided.
edit_session Edit Keyboardia session ~178
Make one narrow, retry-safe edit to an existing collaborative session. After every attempt, the next Keyboardia call must be get_session for the same session. A successful call includes a backwards-compatible compact snapshot plus an acknowledgement. That snapshot is not authoritative verification; do not make another edit or finish from it. Read with get_session next. Supported operations: add_track, set_track_instrument, set_track_pan, set_steps, and set_tempo. set_steps changes only the named steps; it never replaces a track or session. set_track_instrument replaces only a track's sound source, keeping its pattern, mix, timing, and custom name.
| Name | Type | Req | Description |
|---|---|---|---|
| edit | – | yes | Exactly one narrow session edit. |
| session_id | string | yes | The UUID after /s/ in a Keyboardia share URL. Pass only the UUID, not the full URL. |
No output schema declared.
No examples provided.
export_midi Export Keyboardia session as MIDI ~90
Export the session as a base64-encoded Standard MIDI File, matching what Keyboardia's own Export MIDI produces for the same music. The session is not modified. The result lists any session features a MIDI file cannot carry rather than approximating them silently.
| Name | Type | Req | Description |
|---|---|---|---|
| session_id | string | yes | The UUID after /s/ in a Keyboardia share URL. Pass only the UUID, not the full URL. |
No output schema declared.
No examples provided.
get_session Get Keyboardia session ~53
Read the current tempo and compact track patterns from an existing Keyboardia session.
| Name | Type | Req | Description |
|---|---|---|---|
| session_id | string | yes | The UUID after /s/ in a Keyboardia share URL. Pass only the UUID, not the full URL. |
No output schema declared.
No examples provided.
publish_session Publish Keyboardia session ~83
Freeze the current music into a new immutable session and return its URL. The source session stays editable at its own URL. Only call this when someone explicitly asks to publish; it is never a side effect of editing or exporting.
| Name | Type | Req | Description |
|---|---|---|---|
| session_id | string | yes | The UUID after /s/ in a Keyboardia share URL. Pass only the UUID, not the full URL. |
No output schema declared.
No examples provided.
remix_session Remix Keyboardia session ~76
Copy an existing session — published or editable — into a new editable session that records the original as its source. The source is never modified, so this is how to continue from published work.
| Name | Type | Req | Description |
|---|---|---|---|
| session_id | string | yes | The UUID after /s/ in a Keyboardia share URL. Pass only the UUID, not the full URL. |
No output schema declared.
No examples provided.
What is the Keyboardia MCP server?

Is the Keyboardia MCP server safe to use?
Keyboardia scores 75 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 Keyboardia MCP server expose?
Keyboardia exposes 7 tools: get_session, edit_session, create_session, remix_session, publish_session, and 2 more. Their descriptions and schemas cost roughly 712 tokens of context every time the server is loaded.
Does the Keyboardia MCP server require authentication?
No. We connected to Keyboardia without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
