## Quality 76/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2024-11-05; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 64 (weight 30)

- pass `tools.descriptions`: every tool has a description
- warn `tools.description_length`: 2 tools have descriptions over 1,024 characters, which crowds the context
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: revit_upload (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); revit_get_elements (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); revit_clash_detect (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 3,279 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 8, about 3,279 tokens to load them all
- tool set hash: c9322d5943b93ee70c890a18d9b40fce
- badge: [![protogrid quality](https://protogrid.dev/badge/io.scanbimlabs/revit-mcp.svg)](https://protogrid.dev/servers/io.scanbimlabs/revit-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (8)

- `revit_clash_detect`: When to use: Perform a lightweight clash analysis between two Revit categories (e.g. Mechanical Equipment vs Structural Framing) using bounding-box overlap where available, falling back to shared-Level proximity, then annotate with any matching VDC rules stored in the D1 database.
When NOT to use: Do not use as a substitute for Navisworks Manage for contractual clash reports — this is a first-pass coordination sniff test, not a certified Clash Detective run.
APS scopes: data:read viewables:read (Model Derivative metadata + properties).
Rate limits: APS default ~50 req/min per app per endpoint; Model Derivative translation jobs ~60 req/min; OSS uploads size-limited per file to 100MB for direct upload, larger via resumable.
Errors: 401 APS token expired — refresh. 403 scope insufficient — add viewables:read. 404 URN not found — verify model_id. 429 rate limited — back off. 5xx APS upstream — retry with jitter.
Side effects: Read-only against APS. May read from D1 vdc_rules table if present. Idempotent.
- `revit_export_ifc`: When to use: Kick off a Model Derivative translation of a previously uploaded Revit URN into IFC (IFC2x3 Coordination View 2.0 by default) so the model can be exchanged with non-Autodesk tools (Solibri, BIMcollab, Tekla, openBIM workflows).
When NOT to use: Do not use for SVF/SVF2 web viewing (that happens automatically in revit_upload), and do not call repeatedly while a prior IFC job is still inprogress — poll the manifest instead.
APS scopes: data:read data:write viewables:read (Model Derivative job + manifest).
Rate limits: APS default ~50 req/min per app per endpoint; Model Derivative translation jobs ~60 req/min; OSS uploads size-limited per file to 100MB for direct upload, larger via resumable.
Errors: 401 APS token expired — refresh. 403 scope insufficient — add data:write. 404 URN not found — confirm model_id was translated. 409 not applicable. 429 rate limited — back off. 5xx APS upstream — retry with jitter up to 3x.
Side effects: Creates a Model Derivative job and, on completion, a new IFC derivative inside the model's manifest. Safe to re-run (APS deduplicates) but each call with x-ads-force may retranslate.
- `revit_get_elements`: When to use: After a Revit model has finished translating, fetch the first ~100 elements belonging to a Revit category (e.g. Walls, Doors, Windows, Structural Columns) with their objectid, name, externalId, and property bag.
When NOT to use: Do not call before translation completes (manifest.status must be success), and do not use for free-text searches across the whole model — filter by category here or use revit_run_schedule for tabular views.
APS scopes: data:read viewables:read (Model Derivative metadata + properties).
Rate limits: APS default ~50 req/min per app per endpoint; Model Derivative translation jobs ~60 req/min; OSS uploads size-limited per file to 100MB for direct upload, larger via resumable.
Errors: 401 APS token expired — refresh. 403 scope insufficient — add viewables:read. 404 URN not found — confirm model_id and that translation has run. 429 rate limited — back off. 5xx APS upstream — retry with jitter.
Side effects: Read-only. Idempotent.
- `revit_get_parameters`: When to use: Enumerate the Revit parameters (type + instance) that appear on elements in a given category, or on one specific element by objectid. Returns unique values per parameter and how many elements carry it — ideal for schema discovery before building a schedule.
When NOT to use: Do not use when you just need the elements themselves (use revit_get_elements), or to modify values — this is read-only.
APS scopes: data:read viewables:read (Model Derivative metadata + properties).
Rate limits: APS default ~50 req/min per app per endpoint; Model Derivative translation jobs ~60 req/min; OSS uploads size-limited per file to 100MB for direct upload, larger via resumable.
Errors: 401 APS token expired — refresh. 403 scope insufficient — add viewables:read. 404 URN not found — verify model_id. 429 rate limited — back off. 5xx APS upstream — retry with jitter.
Side effects: Read-only. Idempotent.
- `revit_get_sheets`: When to use: Enumerate the drawing sheets (title blocks with sheet number + sheet name like 'A-101: First Floor Plan') published from a translated Revit model, so an agent can pick which sheet to render, review, or cross-reference.
When NOT to use: Do not use to list model views like floor plans or 3D views (use revit_get_views) — this returns only 2D sheet entries.
APS scopes: data:read viewables:read (Model Derivative metadata + object tree).
Rate limits: APS default ~50 req/min per app per endpoint; Model Derivative translation jobs ~60 req/min; OSS uploads size-limited per file to 100MB for direct upload, larger via resumable.
Errors: 401 APS token expired — refresh. 403 scope insufficient — add viewables:read. 404 URN not found — check model_id. 429 rate limited — back off. 5xx APS upstream — retry with jitter.
Side effects: Read-only. Idempotent.
- `revit_get_views`: When to use: Return every view (both 2D — floor plans, ceiling plans, elevations, sections, sheets — and 3D — default {3D}, perspective views, isometric views) in the translated Revit model, including each view's GUID, name, role, and whether it is the master view.
When NOT to use: Do not use when you only want drawing sheets (use revit_get_sheets) or element data inside a view (use revit_get_elements / revit_run_schedule).
APS scopes: data:read viewables:read (Model Derivative metadata + object tree).
Rate limits: APS default ~50 req/min per app per endpoint; Model Derivative translation jobs ~60 req/min; OSS uploads size-limited per file to 100MB for direct upload, larger via resumable.
Errors: 401 APS token expired — refresh. 403 scope insufficient — add viewables:read. 404 URN not found — check model_id. 429 rate limited — back off. 5xx APS upstream — retry with jitter.
Side effects: Read-only. Idempotent.
- `revit_run_schedule`: When to use: Build a tabular, spreadsheet-style schedule (rows = elements matching a keyword, columns = up to 15 shared parameters) from a translated Revit model — useful for Door Schedules, Wall Schedules, Room Schedules, and QA/QC exports.
When NOT to use: Do not use when you only need raw element metadata (use revit_get_elements) or parameter schema (use revit_get_parameters).
APS scopes: data:read viewables:read (Model Derivative metadata + properties).
Rate limits: APS default ~50 req/min per app per endpoint; Model Derivative translation jobs ~60 req/min; OSS uploads size-limited per file to 100MB for direct upload, larger via resumable.
Errors: 401 APS token expired — refresh. 403 scope insufficient — add viewables:read. 404 URN not found — check model_id. 429 rate limited — back off. 5xx APS upstream — retry with jitter.
Side effects: Read-only. Idempotent.
- `revit_upload`: When to use: Ingest a Revit (.rvt / .rfa / .rte / .rft) file into Autodesk Platform Services by downloading it from a publicly reachable URL, uploading it to an OSS bucket, and starting an SVF2 translation so downstream revit_* tools can read elements, parameters, sheets, and views.
When NOT to use: Do not call if you already have a translated URN (use the existing model_id instead), if the file is not a Revit source file, or if the URL requires authentication the worker cannot satisfy.
APS scopes: data:read data:write data:create bucket:read bucket:create viewables:read (OSS bucket create + object PUT + Model Derivative job).
Rate limits: APS default ~50 req/min per app per endpoint; Model Derivative translation jobs ~60 req/min; OSS uploads size-limited per file to 100MB for direct upload, larger via resumable.
Errors: 401 APS token expired — refresh credentials and retry. 403 scope insufficient — request data:write + bucket:create. 404 bucket/object not found — confirm bucket was created. 409 bucket exists — safe to ignore, reuse it. 429 rate limited — back off with exponential delay. 5xx APS upstream — retry with jitter up to 3x, then surface.
Side effects: Creates a new transient OSS bucket named scanbim-revit-<timestamp>, uploads the object, and starts a Model Derivative translation job. NOT idempotent — each call creates a fresh bucket and new URN.
