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 | $0.00084 | $0.02213 |
| Opus 5 | $0.00042 | $0.01107 |
| Sonnet 5 | $0.00017 | $0.00443 |
| Haiku 4.5 | $0.00008 | $0.00221 |
Grade A, and why
use-geogebra-mcp 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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 240 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Use GeoGebra MCP
Use this skill when the user wants an AI coding agent to operate GeoGebra through this project's MCP server. The intended path is:
AI agent -> MCP stdio -> Python geogebra-mcp-server -> Node daemon -> GeoGebra Web Runtime or Classic 6 CDP -> ggbApplet API
Core Rules
- Prefer the installed console command
geogebra-mcp-server; usepython <repo>/geogebra_mcp_server.pyas the source-tree fallback. - Prefer structured MCP tools:
geogebra_run_commandsandgeogebra_create_construction. - Use legacy JSON-string tools only for older clients:
geogebra_batchandgeogebra_draw_mechanism. geogebra_statusis safe as a first call: if GeoGebra is closed, the server should attempt auto-launch.- Do not ask the user to manually open GeoGebra until auto-launch and diagnostics have been attempted.
- Do not kill an already-open GeoGebra session by default. Only set
GEOGEBRA_RESTART_EXISTING=1after the user confirms their GeoGebra work is saved.
Setup From Source
From the repository root:
For MATLAB Agentic Toolkit style automated setup, prefer:
python scripts/setup_geogebra_mcp.py
This installs dependencies, writes common global MCP client config, copies bundled skills, and runs diagnostics.
Manual setup:
npm install
python -m pip install -e .
geogebra-mcp-doctor
Expected geogebra-mcp-doctor behavior:
[OK] daemon_jsand[OK] package_jsonmean package resources are present.[OK] geogebra_installmeans GeoGebra Classic 6 was found (desktop backend only; skipped for Web Runtime).[OK] puppeteermeans Chromium can be launched for Web Runtime.[FAIL] cdp_port: localhost:9222is acceptable for desktop backend if GeoGebra is currently closed; the first MCP tool call should auto-launch it.- For Web Runtime failures, check
[OK] web_assetsand[OK] puppeteer; runnode scripts/smoke_web_runtime.js.
If geogebra-mcp-doctor is missing, install the package first:
python -m pip install -e .
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

use-geogebra-mcp is a skill published in the GitHub repository 123pc/Geogebra_mcp (4 stars, last pushed 3mo ago), licensed MIT. It adds 84 tokens to every session and 2,213 once invoked, about $0.0004 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.
