ACC MCP

Enumerate every ACC and BIM 360 project the authenticated APS app can see by walking all accessible hubs and their project lists. When to use: The agent needs to discover project IDs before calling any other tool (e.g. the user says 'show me my projects' or 'find issues in the Tower project' and no project_id is known yet). Also useful to confirm hub membership for a project. When NOT to use: Do not call this repeatedly in a loop — cache the result; if the user already supplied a project_id starting with 'b.', skip discovery. APS scopes: data:read account:read. No write scope needed. Rate limits: APS default ~50 req/min per app per endpoint; BIM 360 hubs endpoints are pageable (limit 200). This tool fans out 1 hubs call + N project calls (one per hub) so call it sparingly on tenants with many hubs. Errors: 401 (APS token expired — refresh and retry once); 403 (app not provisioned in the BIM 360/ACC account — ask user to have an account admin add the APS client_id); 404 (rare, indicates hub deleted mid-call); 429 (rate limit — back off 60s); 5xx (ACC upstream — retry with jitter). Side effects: None. Read-only and idempotent.

Create a new ACC issue (field observation, coordination clash, safety, quality, etc.) in the target project via the APS Construction Issues API. When to use: The user wants to log a new issue — e.g. 'open a high-priority issue about the leaking valve on level 3' or a downstream agent detected a defect during a model review and needs to record it for the project team. When NOT to use: Do not use to modify an existing issue (use acc_update_issue) and do not use for RFIs (use acc_create_rfi). APS scopes: data:read data:write account:read. Rate limits: ACC Issues API limited to ~100 req/min per app; APS default ~50 req/min per endpoint — batch creations with backoff. Errors: 401 (APS token expired — refresh); 403 (user lacks 'Create Issues' permission on the project or scope insufficient — surface to user); 404 (project_id not found — verify the 'b.' prefix and that the project belongs to a hub the app can see via acc_list_projects); 422 (validation — required field like title/description missing or priority enum invalid); 429 (rate limit — retry after 60s); 5xx (ACC upstream — retry with jitter, do not double-create). Side effects: Creates a persistent issue record visible to all project members. NOT idempotent — a retry on a 5xx may create duplicates; dedupe by title before retrying.

Patch an existing ACC issue — change status, priority, assignee, or description via the APS Construction Issues API. When to use: The user asks to close/reopen/escalate an issue, reassign it, or edit its body. Typical agent flow: acc_list_issues → pick an id → acc_update_issue. When NOT to use: Do not use to create issues (acc_create_issue) or to add comments (not supported by this server). APS scopes: data:read data:write account:read. Rate limits: ACC Issues API ~100 req/min per app; APS default ~50 req/min per endpoint. Errors: 401 (APS token expired — refresh); 403 (user lacks edit permission or status transition not allowed by project workflow); 404 (project_id or issue_id not found — verify 'b.' prefix on project_id and that issue_id belongs to that project); 422 (validation — invalid status/priority enum or illegal state transition); 429 (rate limit — back off 60s); 5xx (ACC upstream — retry with jitter). Side effects: Mutates the issue record. Idempotent when the same body is resent (PATCH semantics) — safe to retry.

List and filter issues from a single ACC project (limit 50 per call) via the APS Construction Issues API. When to use: The user or upstream agent needs to review open issues, count issues by status/priority, or look up an issue_id before calling acc_update_issue. E.g. 'show me all critical open issues on the Tower project'. When NOT to use: Do not use to fetch RFIs (use acc_list_rfis) or to search documents. APS scopes: data:read account:read. No write scope required. Rate limits: ACC Issues API ~100 req/min per app; results pageable (limit 50 here, max 200 upstream). For large projects, call once and filter client-side instead of looping. Errors: 401 (APS token expired — refresh); 403 (user lacks 'View Issues' permission on project or scope insufficient); 404 (project_id not found — verify 'b.' prefix and hub membership via acc_list_projects); 422 (invalid filter value — check status/priority spelling); 429 (rate limit — back off 60s); 5xx (ACC upstream — retry with jitter). Side effects: None. Read-only and idempotent.

Create a new Request For Information (RFI) in an ACC project via the APS Construction RFIs API. RFI is created in 'draft' status — the project workflow owner typically transitions it to 'submitted'. When to use: The user needs a formal question-of-record to the design or GC team — e.g. 'raise an RFI asking for clarification on the Level 2 beam schedule'. RFIs are the auditable channel for clarifications; issues are for field observations. When NOT to use: Do not use for informal observations (use acc_create_issue) or to answer an existing RFI (not supported here). APS scopes: data:read data:write account:read. Rate limits: APS default ~50 req/min per endpoint per app. RFIs share the Construction API umbrella with issues (~100 req/min combined). Errors: 401 (APS token expired — refresh); 403 (user lacks RFI create permission on project); 404 (project_id not found — verify 'b.' prefix and hub membership); 422 (validation — subject/question missing or priority enum invalid); 429 (rate limit — back off 60s); 5xx (ACC upstream — retry with jitter, check for duplicate before retrying). Side effects: Creates a persistent RFI record. NOT idempotent — retry on 5xx risks duplicates; dedupe by subject before retrying.

List and filter RFIs from a single ACC project (limit 50 per call) via the APS Construction RFIs API. When to use: The user wants to review open RFIs, count outstanding ones, or look up an RFI ID. E.g. 'how many RFIs are still open on the Tower project?' When NOT to use: Do not use for issues (use acc_list_issues) or document search (use acc_search_documents). APS scopes: data:read account:read. No write scope required. Rate limits: APS default ~50 req/min per endpoint; ACC Construction API shared ~100 req/min cap. Pageable (limit 50 here; upstream max 200). Errors: 401 (APS token expired — refresh); 403 (user lacks RFI view permission); 404 (project_id not found — verify 'b.' prefix and hub membership); 422 (invalid filter value); 429 (rate limit — back off 60s); 5xx (ACC upstream — retry). Side effects: None. Read-only and idempotent.

Full-text search the ACC Docs repository of a project for drawings, specs, submittals, and other files via the APS Data Management search endpoint. When to use: The user wants to find a document by keyword (filename, sheet number, or metadata match). E.g. 'find the latest A-201 sheet' or 'search for mechanical specs on Tower project'. When NOT to use: Do not use to upload a file (use acc_upload_file); do not use to fetch issues/RFIs. If you already have a document URN, fetch it directly with an agent that has Data Management folder/item access. APS scopes: data:read account:read. No write scope required. Rate limits: APS Data Management ~50 req/min per app per endpoint; pageable (limit 200 upstream). Avoid tight query loops. Errors: 401 (APS token expired — refresh); 403 (user lacks Docs view permission on the project); 404 (project_id not found — verify 'b.' prefix and hub membership); 422 (invalid filter syntax — simplify query text); 429 (rate limit — back off 60s); 5xx (ACC upstream — retry with jitter). Side effects: None. Read-only and idempotent.

Upload a file from a public source URL into an ACC project folder. Runs the full four-step APS Data Management flow: top-folder discovery → storage object creation → OSS PUT of bytes → first-version item creation. When to use: The user wants to push a document/photo/model into ACC Docs — e.g. 'upload this site photo to the Tower project Photos folder' or an automation needs to archive an exported report into Project Files. When NOT to use: Do not use for files already in ACC; do not use for files behind auth-gated URLs (fetch step is an unauthenticated GET). For very large files (>100MB), prefer the chunked/signed-S3 upload flow, not this single-PUT implementation. APS scopes: data:read data:write data:create account:read. Rate limits: APS Data Management ~50 req/min per endpoint; OSS upload bandwidth typically 100 MB/min per app. This tool issues 3–5 APS calls per upload, so budget accordingly. Errors: 401 (APS token expired — refresh); 403 (user lacks folder write permission — ask account admin to grant 'Edit' on folder); 404 (project_id not found or folder_path does not match any top folder — verify 'b.' prefix, hub membership, and folder name); 422 (invalid file_name or conflicting version); 429 (rate limit — back off 60s); 5xx (ACC/OSS upstream — retry with jitter BUT be cautious: storage object may already be created so reuse, do not re-create). Also: if source file_url returns non-2xx, the tool throws before touching ACC. Side effects: Creates a storage object, uploads bytes, and creates a versioned item in the target folder. NOT idempotent — a retry may create a duplicate item with a new version. Surface the returned item_id to the user to avoid re-uploads.

Fetch the full ACC project metadata record (name, type, status, dates, extension attributes) for a single project via APS Data Management. If hub_id is omitted the tool picks the first accessible hub, which may be wrong on multi-hub tenants. When to use: The user asks 'tell me about project X' or an agent needs project metadata (start/end dates, type, Forma/BIM 360 flavor) before deciding which downstream tool to call. When NOT to use: Do not use as a cheap existence check — prefer acc_list_projects which returns hub_id with every project and is one call regardless of tenant size. APS scopes: data:read account:read. Forma / BIM 360 hubs endpoints only require data:read. Rate limits: APS default ~50 req/min per endpoint; BIM 360 hubs endpoints pageable (limit 200). Cache results for the session. Errors: 401 (APS token expired — refresh); 403 (user lacks project view or app not in account); 404 (project not in the chosen hub — supply the correct hub_id, or call acc_list_projects first); 422 (malformed project_id — confirm 'b.' prefix); 429 (rate limit — back off 60s); 5xx (ACC upstream — retry). Side effects: None. Read-only and idempotent.
