Sitecore AI MCP Server

A Model Context Protocol (MCP) server that exposes two read tools over the SitecoreAI / XM Cloud Content Management GraphQL API:

Tool

What it does

get_item_detail

Fetch one item's full detail: id, name, path, template name, display name, all fields, children count

list_items

List an item's immediate children, optionally filtered by template

It runs over stdio, so any MCP client (Claude Desktop, Claude Code, etc.) can launch it as a local subprocess. Authentication uses the OAuth 2.0 client-credentials grant, with an in-memory token manager that caches and proactively refreshes the access token before it expires.


1. Prerequisites

  • Node.js 18+ (uses the built-in global fetch).

  • A Sitecore XM Cloud environment (or a self-hosted CM instance) whose Content Management GraphQL API is enabled.

  • An OAuth client (client id + secret) that is authorised to call that API.

Related MCP server: SitecoreMCP

2. Install & build

npm install
npm run build

This compiles src/** to dist/**. The executable entrypoint is dist/index.js.

3. Configure environment variables

Copy the example file and fill in the values:

cp .env.example .env

Variable

Required

Description

SITECORE_API_URL

Content Management GraphQL endpoint, e.g. https://<cm-host>/sitecore/api/authoring/graphql/v1

SITECORE_TOKEN_URL

OAuth token endpoint (identity server), e.g. https://auth.sitecorecloud.io/oauth/token

SITECORE_CLIENT_ID

OAuth client id

SITECORE_CLIENT_SECRET

OAuth client secret

SITECORE_SCOPE

OAuth scope, if your identity server requires one

SITECORE_AUDIENCE

OAuth audience, if your identity server requires one

The server never logs the client secret or the access token. Errors are surfaced with a category (auth, forbidden, not_found, invalid_template, graphql, network, config) and a short, secret-free detail string.

Access policy (deny-by-default)

Every tool call passes through a path-based policy before any field values or children are read:

  1. Zero-network deny — the well-known Sitecore protected roots (/sitecore/system, /sitecore/templates, /sitecore/layout) have fixed, public GUIDs, so a request for one is refused with no network call at all.

  2. Path gate — for every other id, a minimal path-only lookup runs first, the policy decides, and only then is the item's content fetched. Anything outside the allow-list is denied by default; a denial surfaces as a [forbidden] tool error.

Variable

Default

Purpose

SITECORE_ALLOW_PATHS

/sitecore/content,/sitecore/media library

Readable path prefixes. Anything not matched is denied.

SITECORE_PROTECTED_PATHS

/sitecore/system,/sitecore/templates,/sitecore/layout

Blocked outright unless developer mode is on.

SITECORE_DEVELOPER_MODE

false

When true/1/yes/on, lifts the block on the protected areas.

Why block templates/system/layout by default: an agent that can read — and especially, once write tools exist, edit — a template can take down every page built on it with one plausible-looking change. Keep SITECORE_DEVELOPER_MODE off in any environment an agent reaches unsupervised, and turn it on only for a deliberate developer session.

Because the tools are keyed by item id (an opaque GUID), the id → path mapping for non-root items requires exactly one lightweight metadata lookup; the gate then runs before any content, field values, or (future) mutation is touched.

Where to generate the OAuth client id / secret

XM Cloud (Sitecore Cloud):

  1. Sign in to the XM Cloud Deploy / Cloud Portal.

  2. Open Credentials (Organization settings → Automation client credentials, or the environment's Developer settings).

  3. Create a new client with the scope/role needed to read content via the Authoring/Content GraphQL API.

  4. Copy the generated Client ID and Client Secret into .env.

  5. The token endpoint for Sitecore Cloud is typically https://auth.sitecorecloud.io/oauth/token — set that as SITECORE_TOKEN_URL.

Self-hosted XM / CM instance:

  1. Register an OAuth client in your Sitecore Identity Server configuration (a ClientCredentials grant client) with a client id and secret.

  2. Grant it the API resource/scope for the GraphQL endpoint.

  3. Use your identity server's token endpoint (e.g. https://<cm-host>/sitecore/api/identity/token or the IdentityServer /connect/token) as SITECORE_TOKEN_URL.

The exact GraphQL schema differs slightly between endpoints. This server targets the XM Cloud Authoring & Management GraphQL API shape (item(where: { itemId, language, version }), fields { nodes { name value } }, children { nodes / totalCount }). If your endpoint uses a different schema, adjust the queries in src/tools/getItemDetail.ts and src/tools/listItems.ts.

4. Register the server in an MCP client

Claude Desktop (claude_desktop_config.json)

Location:

  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

  • Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "sitecore-ai": {
      "command": "node",
      "args": ["C:\\path\\to\\SItecoreAISimpleMCP\\dist\\index.js"],
      "env": {
        "SITECORE_API_URL": "https://<cm-host>/sitecore/api/authoring/graphql/v1",
        "SITECORE_TOKEN_URL": "https://auth.sitecorecloud.io/oauth/token",
        "SITECORE_CLIENT_ID": "your-client-id",
        "SITECORE_CLIENT_SECRET": "your-client-secret"
      }
    }
  }
}

Restart Claude Desktop; the two tools appear under the 🔌 tools menu.

Claude Code

claude mcp add sitecore-ai \
  --env SITECORE_API_URL=https://<cm-host>/sitecore/api/authoring/graphql/v1 \
  --env SITECORE_TOKEN_URL=https://auth.sitecorecloud.io/oauth/token \
  --env SITECORE_CLIENT_ID=your-client-id \
  --env SITECORE_CLIENT_SECRET=your-client-secret \
  -- node C:\\path\\to\\SItecoreAISimpleMCP\\dist\\index.js

5. Usage examples

get_item_detail:

{ "itemId": "110D559F-DEA5-42EA-9C1C-8A5DF7E70EF9", "language": "en" }

list_items (optionally filtered by template):

{
  "parentId": "0DE95AE4-41AB-4D01-9EB0-67441B7C2450",
  "language": "en",
  "templateId": "76036F5E-CBCE-46D1-AF0A-4143F9B557AA"
}

GUIDs may be dashed, braced ({...}), or raw 32-hex — all forms are accepted.

6. Tests

npm test

Unit tests cover:

  • Token manager — grant request shape, caching, proactive refresh before expiry, concurrent-refresh coalescing, invalidate(), and 401/network/config error handling (plus a check that the secret never leaks into errors).

  • get_item_detail — field mapping, defaults, version passthrough, not-found handling, and input validation.

  • list_items — child mapping, template filtering (GUID-form-insensitive), invalid-template detection, empty children, not-found, input validation, and policy enforcement (protected parent by id/path, per-child filtering).

  • Access policy — allow-list matching, protected-area blocking, deny by default, sibling-prefix safety, developer-mode lifting the block, and fromEnv parsing.

Both tool suites mock the GraphQL client; the token-manager suite mocks fetch.

TDQS

A4/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must disclose behavior. It lists the return fields (id, name, path, template name, display name, field names/values, children count), giving a clear expectation of what the tool returns. It does not mention error behavior or permissions, but for a fetch operation this is likely sufficient.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that front-loads the action and resource, followed by a colon and list of returned details. No wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple: one required parameter (itemId), with optional version and language documented in the schema. The description explains the return values thoroughly, and the sibling tool list_items covers the list scenario. The absence of an output schema is compensated by the detailed field list. Complete enough.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

All three parameters have descriptions in the schema (100% coverage), so baseline is 3. The description does not add additional parameter semantics beyond what the schema already provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb 'Fetch' and clearly identifies the resource as a single Sitecore item, listing the fields returned. This distinguishes it from the sibling tool list_items, which likely retrieves multiple items.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description does not explicitly state when to use this tool over list_items. However, the phrase 'single item' implies this is for fetching one item's details, while list_items presumably retrieves multiple. No exclusion or alternative is mentioned, so guidance is only implied.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_itemsList Sitecore child itemsA

List the immediate children of a Sitecore / XM Cloud item. Optionally filter by template id. Returns id, name, path, template name and display name.

ParametersJSON Schema
NameRequiredDescriptionDefault
languageNoLanguage/locale code, e.g. 'en' or 'en-US'. Defaults to 'en'.en
parentIdYesThe GUID of the parent item whose immediate children should be listed.
templateIdNoOptional template GUID. When provided, only children of this template are returned.

TDQS

A3.8/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the burden of behavioral disclosure. It does add useful details: lists only immediate children, supports an optional template filter, and specifies the returned fields (id, name, path, template name, display name). However, it omits other behavioral aspects such as sorting, pagination, error behavior when parentId is invalid, or language handling. It provides some transparency but not comprehensive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two concise sentences, front-loaded with the core purpose ('List the immediate children'). Every clause adds value: the scope ('immediate'), the optional filter, and the return fields. No fluff or redundant repetition of the title or tool name.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the moderate complexity, full schema coverage, and absence of an output schema, the description is mostly complete. It explains the purpose, the key behavior (immediate children, optional filter), and the return fields. However, it does not mention the language parameter's role or any edge cases, and the sibling tool relationship is not addressed. Still, it provides a solid understanding for an agent to select and use the tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. The description adds little beyond the schema: it mentions 'immediate children' and optional template filter, both of which are already captured in the parameter descriptions. It does not add new meaning about the language parameter or parameter relationships. The schema fully documents the parameters, so the description does not need to compensate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'List' and the resource 'immediate children of a Sitecore / XM Cloud item', which is specific and distinguishes it from the sibling tool get_item_detail that retrieves a single item. It also mentions optional filtering by template ID and the returned fields, making the purpose unmistakable.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for listing immediate children, but does not explicitly state when to use this tool versus the sibling get_item_detail, nor does it give guidance on when not to use it. The optional template filter is mentioned, but no contextual triggers or exclusions are provided. The usage is clear by implication but not explicitly framed against alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Disambiguation5/5

The two tools have clearly distinct purposes: one fetches detailed information about a single item, while the other lists children of an item. There is no overlap or ambiguity.

Naming Consistency5/5

Both tools follow a consistent verb_noun pattern: 'get_item_detail' and 'list_items'. The naming is predictable and conventional.

Tool Count3/5

With only 2 tools, the server feels minimal but not unreasonable for a focused read-only item browsing scenario. The count is borderline per the calibration.

Completeness2/5

The tools only support reading item details and listing children. Missing write operations (create, update, delete), search, or other content management features leave significant gaps for a Sitecore server.
