## About

# requarks-wiki-mcp

MCP server for a [Wiki.js](https://js.wiki/) instance that lets agents use it like a knowledge base.

Features:

- **29 tools** (19 read + 10 write) covering pages, comments, tags, assets, users, navigation, and system info.
- Search, list, and browse pages for retrieval workflows (RAG-like usage).
- Fetch page content by path or page ID, view version history and restore previous versions.
- Browse site hierarchy with page tree, page links graph, and navigation structure.
- Full comment system: list, read, create, update, and delete comments on pages.
- Asset and folder browsing for media file discovery.
- User context: current user profile and user search.
- System diagnostics: version info, site config, and navigation tree.
- Tag management: list, search, update, and delete tags.
- Optional page create/update/delete/move/restore tools with explicit safety gates.
- Built-in resources: markdown syntax guide, Mermaid diagram guide, and API permissions guide.
- Typed error taxonomy with LLM-friendly error messages.
- GraphQL client with timeout, exponential-backoff retry, and request correlation.
- Security hardening: sensitive field filtering, URL validation, input length limits.

## Requirements

- Node.js 20+
- A reachable Wiki.js hostname
- Wiki.js API key (JWT) with proper permissions

```bash
cp .env.example .env
npm install

# Optional extra safety gate for writes. If set, write tools must pass matching confirm.
WIKI_MUTATION_CONFIRM_TOKEN=
WIKI_MUTATION_DRY_RUN=true
# Comma-separated path prefixes without leading slash (empty = no prefix restriction)
WIKI_ALLOWED_MUTATION_PATH_PREFIXES=

Wiki.js prerequisite (GraphQL + API key):

- This MCP uses Wiki.js GraphQL internally.
- In Wiki.js admin, go to `Administration -> API` and enable API access.
- Create an API key and set it as `WIKI_API_TOKEN`.

## Register MCP Via Local Path (Without npm Publish)

You can register this MCP server directly from your local project path without publishing/installing from npm.

1. Build in this repository

```bash
npm install
npm run build
```

2. Register local absolute path in `~/.mcp.json`

```json
{
  "mcpServers": {
    "requarks-wiki-local": {
      "command": "node",
      "args": ["/absolute/path/to/requarks-wiki-mcp/dist/index.js"],
      "env": {
        "WIKI_BASE_URL": "https://wiki.your-domain.dev",
        "WIKI_API_TOKEN": "your_wikijs_api_key_jwt",
        "WIKI_GRAPHQL_PATH": "/graphql",
        "WIKI_DEFAULT_LOCALE": "en",
        "WIKI_DEFAULT_EDITOR": "markdown",
        "WIKI_MUTATIONS_ENABLED": "true",
        "WIKI_MUTATION_CONFIRM_TOKEN": "",
        "WIKI_MUTATION_DRY_RUN": "false",
        "WIKI_ALLOWED_MUTATION_PATH_PREFIXES": "",
        "WIKI_HTTP_TIMEOUT_MS": "15000",
        "WIKI_HTTP_MAX_RETRIES": "2"
      }
    }
  }
}
```

Notes:

- Always use an absolute path.
- Re-run `npm run build` after code changes so `dist/index.js` stays up to date.

## Run

Development:

```bash
npm run dev
```

Build + run:

```bash
npm run build
npm start

### Mutation Safety

- When `WIKI_MUTATION_CONFIRM_TOKEN` is set, mutation tools require a matching `confirm` argument.
- When `WIKI_MUTATION_DRY_RUN=true`, write tools return a preview and do not mutate Wiki.js.
- If `WIKI_ALLOWED_MUTATION_PATH_PREFIXES` is set, page and comment-create mutations are limited to those path prefixes.
- All mutation attempts write a structured audit line to stderr.

| ---------------------------------- | --------------------------------------------------------------------------------------------------------------------- |
| `wikijs://markdown-guide`          | Wiki.js markdown syntax guide (CommonMark/GFM + Wiki.js-specific extensions) intended for page authoring and updates. |
| `wikijs://mermaid-guide`           | Mermaid 8.8.2 diagram syntax guide for Wiki.js (9 supported diagram types, unsupported feature warnings, version restrictions). |
| `wikijs://api-permissions-guide`   | Wiki.js API permission model, error codes, and API key configuration guide for self-diagnosing permission errors.     |

## Permission Notes (Wiki.js)

Wiki.js permission behavior can be surprising for API keys. In particular:

- Some operations may require `manage:pages`/`delete:pages` rules at page-rule level.
- Reading `content` may require `read:source` depending on schema/field-level checks.
- Comment operations require `read:comments`, `write:comments`, or `manage:comments`.
- System info and navigation require admin-level API key permissions.

Common error codes:

| Code | Meaning |
| --- | --- |
| 6013 | `PageViewForbidden` — check group permissions + page rules for `read:pages`/`read:source` |
| 6003 | Page does not exist |
| 8002 | `CommentPostForbidden` |
| 8003 | `CommentNotFound` |
| 8004 | `CommentViewForbidden` |
| 8005 | `CommentManageForbidden` |

For more details, read the `wikijs://api-permissions-guide` resource.

## Suggested Minimum API Key Permissions

For read-heavy KB use:

- `read:pages`, `read:source`
- `read:comments` (for comment browsing)
- Page rules allowing those permissions for intended paths/locales

For write workflows:

- `write:pages` (create and update)
- `manage:pages` or `delete:pages` (for delete/move operations)
- `write:comments`, `manage:comments` (for comment mutations)
- `manage:system` (for tag management)

## Security Guidance

- Keep API token server-side only.
- Start with read-only permissions.
- Keep `WIKI_MUTATIONS_ENABLED=false` unless updates are needed.
- Optional hardening: set a strong random `WIKI_MUTATION_CONFIRM_TOKEN` and pass matching `confirm` for write calls.
- Keep `WIKI_MUTATION_DRY_RUN=true` until you are ready for real writes.
- Use `WIKI_ALLOWED_MUTATION_PATH_PREFIXES` to constrain write scope.
- `wikijs_get_system_info` filters sensitive infrastructure fields (dbHost, configFile, etc.) by default.
- `scriptJs`/`scriptCss` fields in page create/update are length-limited (10,000 chars) and include browser execution warnings.
