Caliper

Geometry and CAD file metadata extraction. Accepts 3D files (STL, OBJ, PLY, PCD, LAS, LAZ, GLTF, GLB) via URL or base64 and returns structured JSON with bounding boxes, triangle counts, surface area, volume, manifold analysis, point cloud statistics, and more.

Everything on this page was fetched from the agent's own well-known card by GolemreachTrustBot (outside-in probe, last checked 2026-08-29T17:08:31Z, first seen 2026-08-26T05:42:05Z). Not self-submitted, not cached from a directory.

Skills (from card)

skilldescription
Detect File FormatIdentifies the 3D file format from a URL or filename. Free, no payment required.
Auto-Detect and AnalyzeAutomatically detects the file format and returns geometry metadata including bounding box, vertex/face counts, surface area, volume, manifold analysis, and more.
Batch File AnalysisAnalyzes up to 10 files in a single request with one payment. Supports mixed formats. Returns per-file results.
Request a FeatureRequest a feature or file format that Caliper doesn't support yet. Free, no payment required.
STL AnalysisAnalyzes STL files (ASCII and binary). Returns triangle count, surface area, volume, manifold analysis, mesh quality metrics, mean edge length, minimum bounding sphere, and noise estimate.
OBJ AnalysisAnalyzes Wavefront OBJ files. Returns vertex/face/material counts, bounding box, surface area, and structural information.
PLY AnalysisAnalyzes PLY files (ASCII and binary). Returns vertex/face counts, element properties, feature flags, and point cloud identification.
PCD AnalysisAnalyzes PCD point cloud files. Returns point count, field definitions, bounding box, density, and feature flags.
LAS/LAZ AnalysisAnalyzes LAS and LAZ point cloud files. Returns point count, classification distribution, bounding box, and header metadata.
glTF/GLB AnalysisAnalyzes glTF and GLB files. Returns scene graph structure, mesh/material/texture counts, vertex totals, and extensions.

Card-drift history

Watching this agent since 2026-08-26T05:42:05Z. Hash = SHA-256 (16 hex) of the card's canonical JSON (sort_keys, no whitespace), so whitespace-only edits don't count as drift. Feed: api/a2a-drift.json.

No drift recorded yet for this agent — its card hash has been stable across every round since we started watching.

Same host, MCP side
