These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

ggb_create_session

Create a headless GeoGebra applet session backed by the local bundled GeoGebra Web assets.

ggb_eval_command

Evaluate one or more English GeoGebra input-bar commands in a session through the bundled applet's evalCommandResult API, returning ok/result/labels/error metadata.

ggb_query_commands

Search the bundled GeoGebra command reference by command name, localized name, syntax, examples, tags, and scopes. Use this before ggb_eval_command when command syntax is uncertain.

ggb_eval_cas

Evaluate a GeoGebra CAS expression in a session.

ggb_get_objects

List construction objects with compact type, value, definition, command, visibility, and defined-state metadata.

ggb_get_state

Get the current construction state as XML, base64 .ggb data, or fileJSON. Large results are returned as MCP resources.

ggb_set_state

Replace or load construction state from XML, base64 .ggb data, or fileJSON.

ggb_export_image

Export the active view as PNG, SVG, or full-applet screenshot.

ggb_set_view

Set common view options such as coordinate system, grid visibility, axes visibility, or perspective.

ggb_reset

Clear the construction or reset the applet to its initial construction.

ggb_close_session

Close a GeoGebra browser page and release its session resources.

ggb_list_sessions

List active GeoGebra sessions managed by this MCP server.

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

12/12 tools missing one or more hints — ggb_create_session (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); ggb_eval_command (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); ggb_query_commands (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +9 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tests exist

No test files found

Add tests that exercise each declared tool.

No eval / new Function

7 eval() or new Function() calls — dynamic code execution

Replace eval / Function with explicit parsing or safer alternatives.

Readable source code

37 files are minified or bundled, which is usually build output rather than concealment

Ship unminified, readable source.

Production dependencies are patched

0 critical, 4 high severity in production deps — @modelcontextprotocol/sdk@1.18.0 (high), @modelcontextprotocol/sdk@1.18.0 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 6 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
