Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00026 | $0.00450 |
| Opus 5 | $0.00013 | $0.00225 |
| Sonnet 5 | $0.00005 | $0.00090 |
| Haiku 4.5 | $0.00003 | $0.00045 |
Grade A, and why
gnome-ui-cli scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
The gnome-ui-mcp CLI lets you automate the GNOME desktop from the terminal.
Setup
Install and run via uv:
uv run gnome-ui-mcp
Or via Docker:
./scripts/run-docker-mcp.sh
The server communicates over stdio using JSON-RPC (MCP protocol).
AI Workflow
- Discover: Use
list_applicationsandfind_elementsto locate UI targets - Inspect: Use
accessibility_treeto understand element hierarchy - Act: Use
click_element,type_text,press_keyto interact - Verify: Use
screenshotorassert_elementto confirm results
Quick Test
Send a ping to verify the server is working:
echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"test","version":"0.1"}}}' \
| uv run gnome-ui-mcp
Transport Options
uv run gnome-ui-mcp # stdio (default)
uv run gnome-ui-mcp --transport sse # Server-Sent Events
uv run gnome-ui-mcp --transport streamable-http # Streamable HTTP
Environment Requirements
The server requires these environment variables to be set (they are typically available in a GNOME Wayland session):
DBUS_SESSION_BUS_ADDRESSXDG_RUNTIME_DIRWAYLAND_DISPLAYDISPLAYXDG_SESSION_TYPE
MCP Client Configuration
Add to .mcp.json in your project:
{
"mcpServers": {
"gnome-ui": {
"command": "uv",
"args": ["run", "gnome-ui-mcp"]
}
}
}
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

gnome-ui-cli is a skill published in the GitHub repository asattelmaier/gnome-ui-mcp (1 stars, last pushed 25d ago), licensed MIT. It adds 26 tokens to every session and 450 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
