Read out of the source npm actually ships, at scan time. The package was never executed. Tools registered dynamically at runtime, or hidden inside bundled or minified code, can be missed — so this is a floor on the tool surface, not a complete census of it.

update_entityCreate or update an entity in the spatial world model. Allows specifying position (3D coordinates), orientation (pitch/yaw/roll), bounding box volume, custom properties, tags, and confidence score.

query_entitiesFind entities by keyword query (FTS5 search), type, region, spatial proximity, tags, or status. Alternatively, provide entity_id for single-entity location and historical trajectory lookup.

15 of 15 tools published a description.

Tool names and descriptions are written by the publisher and shown verbatim as inert text. They are the strings an MCP client passes to a model, so Forge scans them for prompt-injection patterns — any finding appears with the security scan above. “Privileged” is a keyword match on the tool name, not an audit of what the tool does: a benign-sounding name can still do anything.

Dependency tree

What one Forge scan resolved from npm metadata on 2026-09-12 — observed resolution, not a publisher declaration.

60 packages resolved · 3 direct · none carrying advisories Resolution stops at depth 4 and 60 packages.

The crawl stopped at the 60-package limit. The rest of the tree was never resolved.

36 more resolved packages are not drawn here (display cap: 24). Every dependency carrying an advisory is drawn regardless of the cap. Full inventory (CycloneDX SBOM)

Declared but not resolved

76 declared dependencies never landed in the tree. They are missing from Forge's resolution, not from the package.

+64 more not listed. The counts by reason above cover all of them.

Not followed: peerDependencies. This tree covers runtime dependencies only, so anything those pull in was never resolved.
