## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-04.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs setuptools.build_meta at install time, a recognised build step with no custom scripting around it.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to Garthnesss/ElfDeckAI).

### 2026-10-28 (score 59)

First indexed and scored.

## MCP tools (22)

### `key_tap` (~32 tokens)

Tap a key on the virtual keyboard.

Input parameters:

- `hold_ms` (integer)
- `key` (string, required)

### `key_down` (~31 tokens)

Hold a key down (release with key_up, or key_release for all).

Input parameters:

- `key` (string, required)

### `key_up` (~20 tokens)

Release a held key.

Input parameters:

- `key` (string, required)

### `key_release` (~33 tokens)

Release every held key at once — the unstick button, for when a caller died mid-hold or state is unknown.

### `pad_press` (~78 tokens)

Tap a gamepad button or D-pad direction. In Steam Deck Gaming Mode, if the game ignores the pad, ElfPad is not Player 1: open Steam > Controller Settings > Reorder Controllers while the game runs and move the non-Deck controller to the top.

Input parameters:

- `button` (string, required)
- `hold_ms` (integer)

### `pad_down` (~71 tokens)

Hold a gamepad button or D-pad direction down. In Steam Deck Gaming Mode, if the game ignores the pad, ElfPad is not Player 1: open Steam > Controller Settings > Reorder Controllers while the game runs and move the non-Deck controller to the top.

Input parameters:

- `button` (string, required)

### `pad_up` (~26 tokens)

Release a held gamepad button or D-pad direction.

Input parameters:

- `button` (string, required)

### `pad_stick` (~68 tokens)

Move an analog stick (x/y in percent, -100..100). Without hold_ms the stick stays; with it, it recenters after.

Input parameters:

- `hold_ms` (integer)
- `side` (string, required)
- `x` (integer, required)
- `y` (integer, required)

### `pad_trigger` (~54 tokens)

Set an analog trigger (percent 0..100). Without hold_ms it stays; with it, it releases after.

Input parameters:

- `hold_ms` (integer)
- `percent` (integer, required)
- `side` (string, required)

### `pad_center` (~18 tokens)

Return sticks, triggers and D-pad to neutral.

### `pad_reset` (~16 tokens)

Release every button and recenter everything.

### `mouse_move` (~61 tokens)

Move the pointer relatively by (dx, dy). Pointer acceleration applies, so prefer mouse_move_to for targeting. Optional glide_ms spreads the move over time.

Input parameters:

- `dx` (integer, required)
- `dy` (integer, required)
- `glide_ms` (integer)

### `mouse_move_to` (~62 tokens)

Move the pointer to (x, y), in the pixel coordinates of the most recent screenshot (0,0 is its top-left corner). Takes a screenshot first if none has been taken yet.

Input parameters:

- `x` (integer, required)
- `y` (integer, required)

### `mouse_click_at` (~64 tokens)

Move the pointer to (x, y) in the pixel coordinates of the most recent screenshot, then click (left by default).

Input parameters:

- `button` (string)
- `hold_ms` (integer)
- `x` (integer, required)
- `y` (integer, required)

### `mouse_click` (~34 tokens)

Click a mouse button at the pointer's current position.

Input parameters:

- `button` (string, required)
- `hold_ms` (integer)

### `mouse_down` (~25 tokens)

Hold a mouse button down (start a drag).

Input parameters:

- `button` (string, required)

### `mouse_up` (~24 tokens)

Release a mouse button (drop the drag).

Input parameters:

- `button` (string, required)

### `mouse_scroll` (~26 tokens)

Scroll the wheel: positive clicks up, negative down.

Input parameters:

- `clicks` (integer, required)

### `mouse_hscroll` (~23 tokens)

Scroll horizontally: positive clicks right.

Input parameters:

- `clicks` (integer, required)

### `mouse_release` (~30 tokens)

Release every held mouse button at once — the unstick button, for when a caller died mid-drag.

### `screenshot` (~69 tokens)

Capture the screen of the machine this server runs on (e.g. a Steam Deck in Desktop Mode) and return it as a PNG image, scaled down if the screen is large. mouse_move_to and mouse_click_at take coordinates in this image's pixels. Requires a graphical session on the server's machine.

### `wait` (~61 tokens)

Wait before the next tool call, in milliseconds. Use it for timing between inputs: queued taps land back-to-back with essentially no gap, and a frame-polled game can merge them into one hold. Bounded like every tap.

Input parameters:

- `ms` (integer, required)

## Common questions

### What is the ElfDeckAI MCP server?

ElfDeckAI is an MCP server listed in the public MCP registry as io.github.Garthnesss/elfdeckai. Virtual keyboard, gamepad and mouse for AI agents on Linux / Steam Deck. This page covers its PyPI package (elfdeckai).

### Is the ElfDeckAI MCP server safe to use?

ElfDeckAI scores 78 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 4 November 2026. Its build provenance is signed and verified. 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 ElfDeckAI MCP server expose?

ElfDeckAI exposes 22 tools: key_tap, key_down, key_up, key_release, pad_press, and 17 more. Their descriptions and schemas cost roughly 926 tokens of context every time the server is loaded.

### Is the ElfDeckAI MCP server still maintained?

ElfDeckAI is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the ElfDeckAI MCP server under?

ElfDeckAI declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
