Blender integration through the Model Context Protocol
Nothing to run from here
Caliper is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

What it does
Geometry and CAD file metadata extraction for STL, OBJ, PLY, PCD, LAS/LAZ, glTF/GLB.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http caliper-mcp https://caliper.fit/mcp/
# 2 — ask your agent for something these tools do
# format_detect, feature_request, format_auto and 7 more
Caliper costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http caliper-mcp https://caliper.fit/mcp/Reconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
10 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Detect the geometry file format from a filename or URL. Returns the detected format name and whether it is currently supported. Use this to check format support before making a paid analysis call. No payment required. Privacy policy: https://caliper.fit/privacy
| Parameter | Type | Required | Notes |
|---|---|---|---|
| filename | string | yes | Filename or URL to check. The format is detected from the file extension. |
Request a feature or format that Caliper doesn't support yet. Free, no payment required. Use this when you need a capability that Caliper doesn't currently offer — especially unsupported file formats (STEP, IGES) or analysis features not yet available. Requests are logged and used to prioritize development. Privacy policy: https://caliper.fit/privacy
| Parameter | Type | Required | Notes |
|---|---|---|---|
| description | string | yes | A short description of the feature or format you need. Examples: 'STEP file support', 'volume comparison between two files', 'export to USD format'. This helps prioritize development. |
Auto-detect geometry file format and extract metadata statistics. Accepts a 3D geometry file via URL or base64 and returns structured metadata: bounding boxes, triangle counts, manifold analysis, point cloud statistics, and more. This is a read-only analysis tool — it does not perform mesh repair, format conversion, or boolean operations. Supported formats: STL, OBJ, PLY, PCD
| Parameter | Type | Required | Notes |
|---|---|---|---|
| file_url | no | HTTP/HTTPS URL of the geometry file to analyze. Preferred for large files (over 200KB). The file format is detected from the URL path extension, so the filename parameter is not needed when using file | |
| file_b64 | no | Base64-encoded file content. Max 200KB decoded. Use file_url for larger files to avoid consuming model context window budget. Default: null (omit if providing file_url instead). | |
| filename | no | Original filename with extension (e.g. 'model.stl'). Required for format detection when using file_b64. Not needed when using file_url (format is detected from the URL path). Default: null. | |
| payment | no | Payment proof as a JSON string. Set this when retrying after a payment_required response. For x402: must contain 'transaction' (on-chain tx hash), 'network', and 'priceToken' from the payment_required |
Extract metadata from an STL file (ASCII or binary). Returns triangle count, bounding box, surface area, volume, manifold analysis (watertight, open edges, non-manifold edges), triangle quality metrics, vertex deduplication count, mean edge length, minimum bounding sphere, and a noise estimate derived from planar region fitting.

Extract metadata from an OBJ file. Returns vertex/normal/texcoord/face counts, triangle/quad/polygon breakdown, material and group counts, bounding box, surface area, and triangulation status.

Extract metadata from a PLY file (ASCII or binary).

No rule-by-rule report on file for this release
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 0.1.1.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish Caliper can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
