Assign a User CMDB Access (Service Cloud ITSM)

Grants a specific user the ability to read and work with CMDB (Configuration Management Database) data by assigning the license-backed CMDB permission sets and their permission-set licenses. Every call runs through the Salesforce-hosted Headless-360 MCP server (server key headless-360) via its four meta-tools (discover, describe, dispatch_readonly, dispatch). The org is derived from the OAuth JWT bound to the current MCP session — the skill never handles an org id, alias, or credentials — so this works identically against production and sandbox with no per-user MCP install.

This is Layer 3 of CMDB setup. It assumes the org-level CMDB gate is already lifted (the feature is ENABLED) — that is a separate skill (service-itsm-agentic-setup-cmdb-configure, Layers 0–2). This skill grants a user access; it does not enable the feature for the org.

The gap this skill closes

Enabling the CMDB feature lifts the org-level gate, but some CMDB reads (e.g. bundleListView) also enforce user-level access. A user with no CMDB permission sets still gets 403 FUNCTIONALITY_NOT_ENABLED ("not enabled for this user") even when the feature is correctly ENABLED for the org. This skill assigns that user the CMDB permission sets so those reads succeed.

This skill is a no-op if the org feature is not enabled. User-level access has no effect until the org-level CMDB feature is ENABLED. If you find the org gate is still closed, stop and tell the user the CMDB feature must be turned on for the org first — see the cross-skill note at the end.

The four CMDB permission sets

Each is a license-backed Standard permission set; assigning it also requires (and this skill assigns) its permission-set license (PSL).

Role	Permission set (Name)	Backing PSL (DeveloperName)	Grants
Reader	ItSrvcCnfgItmReadPermissionSet	ItSrvcCnfgItmReadPsl	Read CMDB configuration items
Owner	ItSrvcCnfgItmOwnerPermissionSet	ItSrvcCnfgItmOwnerPsl	Own / edit configuration items
Type Reader	ItSrvcCnfgItmTypReadPermissionSet	ItSrvcCnfgItmTypReadPsl	Read configuration-item types
Type Manager	ItSrvcCnfgItmTypManagerPermissionSet	ItSrvcCnfgItmTypMgrPsl	Manage configuration-item types

For read-only CMDB access, Reader (+ Type Reader) is the minimal set. For users who edit CMDB records, add Owner; for those who manage the type catalog, add Type Manager. If the user does not specify a role, ask (see Clarifying questions) — default to Reader + Type Reader for a viewer.

Bundle management needs Type Manager. If the user's goal is to install or manage CMDB content bundles (or they hit a 403 on a bundle-management read such as GET /connect/cmdb/bundles/details), the role that clears it is Type Manager — a user holding only Reader / Owner / Type Reader still gets 403 FUNCTIONALITY_NOT_ENABLED on bundle operations. Assign Type Manager (with its own backing PSL, ItSrvcCnfgItmTypMgrPsl) for anyone who deploys or manages bundles.

Scope

• In scope: resolving the target user, resolving the requested CMDB permission set(s), checking existing assignments, assigning the permission-set license(s) and permission set(s), and verifying.
• Out of scope: enabling the CMDB feature / provisioning the ITOM tenant (Layers 0–2 — service-itsm-agentic-setup-cmdb-configure), installing content bundles, CMDB record CRUD, creating custom permission sets, or org-permission/edition changes.

Mechanism

All operations dispatch through headless-360 MCP tools. Reads go through mcp__headless-360__dispatch_readonly, writes through mcp__headless-360__dispatch — both take raw HTTP: {"url": "<path>", "method": "GET|POST", "body"?: {...}, "queryParams"?: {...}} — not {operation_id, arguments}. See references/mcp-invocation.md for the exact url / method / body of every call. The four tools:

• mcp__headless-360__discover — semantic search over the indexed operation catalog. The standard /query and /sobjects/... REST routes this skill uses are not always indexed, so a miss does not mean the route is absent — dispatch the exact path directly (see references/mcp-invocation.md).
• mcp__headless-360__describe — pull the full input schema and canonical route before any POST.
• mcp__headless-360__dispatch_readonly — the dispatcher for every read (GET).
• mcp__headless-360__dispatch — the dispatcher for every write (POST/PATCH).

The skill never handles credentials — the org is bound to the current OAuth session. If a dispatch* call returns an auth error, tell the user to re-authenticate the headless-360 MCP connection (and confirm the session points at the intended org), then stop.

Clarifying questions

Ask only what you cannot infer from conversation:

• Which user? The username (or a name/email you can resolve to exactly one user). If the request is "give me access" / "for the current user", resolve the running user.
• Which role(s)? Reader, Owner, Type Reader, Type Manager — or "read-only access" (→ Reader + Type Reader). Default to Reader + Type Reader for a viewer if unspecified. If the user installs or manages CMDB content bundles (or is fixing a bundle-management 403), include Type Manager — bundle operations 403 without it.
• Which org? Confirm the target org and state plainly that this org will be modified (assigning permission sets is a write). For production, get explicit confirmation.

Do not re-ask for anything the user already provided; pre-populate and note "(from conversation)".

Workflow

Always read before you write: run the read-only checks before any assignment. All assignments are per-user and idempotent — a duplicate assignment must be treated as already-done, not an error.

Step 1 — Confirm the org-level CMDB feature is enabled (read-only, prerequisite)

User access is meaningless until the org gate is lifted. Read the feature status:

dispatch_readonly({ "url": "/services/data/v67.0/connect/setup/discovery/feature/service-cloud-itsm-cmdb-integration/status", "method": "GET" })

• status == ENABLED → proceed.
• status != ENABLED (or the call returns 403 FUNCTIONALITY_NOT_ENABLED) → STOP. Tell the user, in plain language, that CMDB has to be turned on for the org before a user can be given access, and point them to the CMDB feature-enable skill (see the cross-skill note). Do not assign anything.

Step 2 — Resolve the target user (read)

For "the current user" / "me" / "my own user" (do NOT use USER_ID() — it is Apex-only and is rejected by the REST query API; do NOT rely on /chatter/users/me or /connect/user-profiles/me — they return 403 FUNCTIONALITY_NOT_ENABLED when Chatter/Communities are off). Instead read the API root and parse the identity URL:

dispatch_readonly({ "url": "/services/data/v67.0/", "method": "GET" })

The response identity field is a URL ending in /<orgId>/<userId> (the user Id is the last path segment and starts with 005). Use that Id directly as the target user, or confirm it:

dispatch_readonly({ "url": "/services/data/v67.0/query", "method": "GET", "queryParams": { "q": "SELECT Id, Username, Name, IsActive FROM User WHERE Id = '<userId>'" } })

For a named user (username / email supplied):

dispatch_readonly({ "url": "/services/data/v67.0/query", "method": "GET", "queryParams": { "q": "SELECT Id, Username, Name, IsActive FROM User WHERE Username = '<username>'" } })

• Exactly one active user → capture the Id.
• Zero results → STOP; tell the user no matching user was found and ask them to confirm the username.
• More than one → STOP; list the candidates (Name + Username) and ask which one.
• User inactive → warn the user; assignment can still proceed but the access takes effect only when the user is active.

Step 3 — Resolve the requested permission set(s) (read)

For each requested role, resolve the permission set and its backing license:

dispatch_readonly({ "url": "/services/data/v67.0/query", "method": "GET", "queryParams": { "q": "SELECT Id, Name, LicenseId FROM PermissionSet WHERE Name = '<psName>'" } })

Use the Name values from the table above. Capture each Id (the permission set) and LicenseId (the PSL to assign). If a permission set is not found, the org likely is not CMDB-licensed — stop and report that CMDB does not appear to be set up on this org.

Step 4 — Check existing assignments (read — idempotency)

For each target user + permission set, check whether the assignment already exists:

dispatch_readonly({ "url": "/services/data/v67.0/query", "method": "GET", "queryParams": { "q": "SELECT Id FROM PermissionSetAssignment WHERE AssigneeId = '<userId>' AND PermissionSetId = '<psId>'" } })
dispatch_readonly({ "url": "/services/data/v67.0/query", "method": "GET", "queryParams": { "q": "SELECT Id FROM PermissionSetLicenseAssign WHERE AssigneeId = '<userId>' AND PermissionSetLicenseId = '<pslId>'" } })

If both already exist for a role, that role is already assigned — skip its writes and record it as already-done. Only assign what is missing.

Step 5 — Assign the permission-set license, then the permission set (write — confirm first)

Confirm the target user, org, and role(s) with the user, then for each missing role assign the PSL first, then the permission set:

dispatch({ "url": "/services/data/v67.0/sobjects/PermissionSetLicenseAssign", "method": "POST", "body": { "AssigneeId": "<userId>", "PermissionSetLicenseId": "<pslId>" } })

dispatch({ "url": "/services/data/v67.0/sobjects/PermissionSetAssignment", "method": "POST", "body": { "AssigneeId": "<userId>", "PermissionSetId": "<psId>" } })

• 201 → assigned.
• 400 DUPLICATE_VALUE → the user already had it; treat as success (idempotent), not a failure.
• A license-limit error (e.g. INSUFFICIENT_ACCESS / no seats) → STOP for that role; tell the user the CMDB license has no available seats and how many are in use (see references/mcp-invocation.md for the seat query). Do not retry.

Step 6 — Verify (read — do NOT trust the POST response alone)

Re-run the Step 4 queries. Confirm each requested role now has both a PermissionSetAssignment and a PermissionSetLicenseAssign for the user. Report per-role: assigned / already had it. Only roles confirmed present in this read count as done.

Rules / Constraints

Constraint	Rationale
Confirm the org feature is ENABLED before assigning	User access has no effect until the org-level CMDB gate is lifted; assigning first would be a misleading no-op
Resolve the user to exactly one record before writing	Assigning to the wrong (or an ambiguous) user is hard to reverse and a security concern
Read existing assignments before every assign	Assignment is per-user; re-assigning throws DUPLICATE_VALUE — skip what already exists
Assign the PSL before the permission set	The permission set is license-backed; the license seat must be held for the assignment to stick
Treat DUPLICATE_VALUE as success	It means the user already has that access — idempotent, not an error
Never create or edit permission sets	This skill only assigns the standard CMDB permission sets; authoring perm sets is out of scope
Confirm the target org, user, and each write with the user	These are real changes granting a user data access on a live org
Never expose internal jargon to the user	Keep record IDs, HTTP status codes (403/400/…), API error codes (FUNCTIONALITY_NOT_ENABLED, DUPLICATE_VALUE), object names (PermissionSetLicenseAssign), developer names (ItSrvcCnfgItmReadPsl), and tooling internals (dispatch, headless-360) out of user-facing output. Use human-readable role names and plain language

---

Verification checklist

• Org CMDB feature confirmed ENABLED before any assignment?
• Target user resolved to exactly one record?
• Each requested role's permission set and backing license resolved?
• Existing assignments checked before writing (idempotency)?
• For each requested role, both the permission set and its license are assigned?
• Verified by a post-write read (not the POST response alone)?
• Confirmed the target org, user, and each write with the user first?

Output expectations

CMDB Access Assignment — Complete (via service-itsm-agentic-setup-cmdb-access-assign)

Target org: <org>
User: <name> (<username>)

  Configuration Item Reader ......... Assigned
  Configuration Item Type Reader .... Already had access

This user can now read CMDB data in this org. If they still can't, confirm the org's
CMDB feature is turned on (that's a separate setup step).

Keep internal jargon out of user-facing output (no record IDs, HTTP status codes, error codes, object or developer names). If any step fails, stop and tell the user — in plain language — which part didn't succeed and what it means for them. Translate any raw error (e.g. a 403 or FUNCTIONALITY_NOT_ENABLED) into what it means ("CMDB isn't turned on for this org yet"), rather than echoing the code.

---

Common failures (surface these in plain language)

Symptom	Likely cause	What to tell the user
Feature status not ENABLED (or 403 on the status read)	Org-level CMDB gate not lifted	CMDB must be turned on for the org first; this is a separate setup step — point to the feature-enable skill
Permission set not found	Org is not CMDB-licensed / not set up	CMDB does not appear to be available on this org; confirm it is licensed and enabled
403 FUNCTIONALITY_NOT_ENABLED on a bundle-management read (e.g. bundles/details, bundleListView) after assignment, feature ENABLED	The user holds Reader/Owner/Type Reader but not Type Manager — bundle operations require it	Assign Type Manager — this role is required for CMDB bundle management; the other CMDB roles do not cover bundle operations
400 DUPLICATE_VALUE on assign	User already has that access	Not an error — report the role as already assigned
License-limit / no-seats error on assign	CMDB permission-set license seats exhausted	Report seats in use vs available; a seat must free up (or more licenses added) before assigning
dispatch* auth error	headless-360 MCP session not authenticated / token expired	Re-authenticate the headless-360 MCP connection and confirm the session points at the intended org

Cross-skill integration

When	Skill
The org CMDB feature is not enabled yet (org gate still closed)	service-itsm-agentic-setup-cmdb-configure (Layers 0–2 — enable the feature first, then return here)
The user needs the CMDB base content bundle installed	service-itsm-agentic-setup-cmdb-bundle-deploy (Layer 4 — content, separate from user access). That skill's bundle-management reads require the user hold Type Manager, so assign it here first
