How do I install the Carbone MCP server?
Carbone MCP is a hosted endpoint at https://mcp.carbone.io/, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

convert_document Convert Document ~1,576
Convert any document to another format without storing a template. Supports 100+ input/output format combinations: Office documents, PDFs, images, web pages, spreadsheets, and more. The source file can be a local path, a URL, or a base64 string. Carbone tags are PRESERVED, not resolved: converting a template keeps every {d.field} intact, so this is also how you proof a template in another format (DOCX template → PDF, or DOCX → ODT while it stays a template). Use render_document instead when you need data injection ({d.field} tags resolved), translations, or batch generation. Common conversions: DOCX → PDF (file: "report.docx", convertTo: "pdf"; add converter: "I" for the fastest DOCX→PDF path), XLSX → PDF (file: "data.xlsx", convertTo: "pdf"), PPTX → PDF (file: "slides.pptx", convertTo: "pdf", converter: "O" for best fidelity), HTML → PDF (file: "page.html", convertTo: "pdf", converter: "C" for full CSS/JS rendering), DOCX → HTML (file: "doc.docx", convertTo: "html"), XLSX → CSV (file: "sheet.xlsx", convertTo: "csv"), PDF → PNG (file: "doc.pdf", convertTo: "png"), PPTX → PNG (first slide as image), MD → PDF (file: "readme.md", convertTo: "pdf").
| Name | Type | Req | Description |

No examples provided.
delete_template Delete Template ~152
Delete a stored Carbone template. This is a soft delete: the template is marked for garbage collection and removed after a delay (default 24 hours). You can delete by Template ID (removes all versions) or by Version ID (removes only that specific version). For immediate or scheduled deletion, use update_template_metadata with expireAt = 42000000000 (NOW) or a future Unix timestamp.
| Name | Type | Req | Description |
|---|---|---|---|
| templateId | string | yes | Template ID (64-bit) or Version ID (SHA-256) to delete. Template ID — deletes the template record and all its versions. Version ID — deletes only that specific version, leaving other versions intact.… |
No output schema declared.
No examples provided.
download_template Download Template ~359
Download the original source file of a stored Carbone template (e.g. the DOCX, XLSX, PPTX, or HTML file that was uploaded). Use this to inspect, edit, or back up a template. Pass a Template ID to download the currently deployed version, or a Version ID to download a specific version. Set sample:true to fetch the JSON sample dataset stored with the template instead of the template file itself.
| Name | Type | Req | Description |
|---|---|---|---|
| asAttachment | boolean | – | If true, return the template as a downloadable file attachment (base64 resource) instead of inline text/image. Useful in HTTP mode where outputPath is unavailable. Default: false. Ignored when output… |

No output schema declared.
No examples provided.
get_api_status API Status ~40
Check Carbone API health and version. Returns the current API version and a status message. Useful for verifying connectivity and confirming which Carbone version is active.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| message | string | yes | Status message returned by the API. |
| version | string | yes | The running Carbone API version. |
No examples provided.
get_capabilities Capabilities ~46
Returns a summary of all Carbone capabilities: supported formats, features, tool usage examples, and links to full documentation. Call this first if you are unsure what Carbone can do.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_categories List Categories ~57
List all template categories currently in use in your Carbone account. Categories act like folders for organising templates (e.g. "invoices", "legal", "hr"). Use the returned names as the category filter in list_templates or upload_template.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| categories | array | yes | Template category names in use. |
No examples provided.
list_tags List Tags ~76
List all tags currently used across templates in your Carbone account. Tags are free-form labels attached to templates (e.g. "sales", "billing", "v2"). Note: the Carbone API does not support filtering list_templates by tag — use this tool to discover available tags, then call list_templates and filter the results manually.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| tags | array | yes | Template tag names in use. |
No examples provided.
list_templates List Templates ~335
List stored Carbone templates with filtering, search, and pagination. Filter by Template ID, Version ID, category, or upload origin. Use includeVersions to see the full version history of each template. Supports cursor-based pagination for large collections. Note: filtering by tags is not supported by the Carbone API — use list_tags to discover tags, then filter results manually. Note: templates uploaded with versioning disabled appear with id = null and are identified only by their versionId — pass that versionId where a Template ID is expected (e.g. delete_template, download_template).
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Filter by category (e.g. "invoices", "legal"). |
| cursor | string | – | Pagination cursor from the previous response nextCursor field. Use to fetch the next page. |
| id | string | – | Filter by Template ID (64-bit format). Cannot be a Version ID. |
| includeVersions | boolean | – | If true, returns all versions for each template. Default: false (only deployed version). |
| limit | integer | – | Maximum number of results to return, between 1 and 100. Default: 100. Use cursor to page beyond that. |
| origin | integer | – | Filter by upload origin. 0 = API, 1 = Carbone Studio, 2 = Salesforce, 3 = Odoo, 4 = HubSpot. Templates created through this MCP are origin 0. |
| search | string | – | Fuzzy search in template names, or exact match on Template ID / Version ID. |
| versionId | string | – | Filter by Version ID (SHA-256 format). |
| Name | Type | Req | Description |
|---|---|---|---|
| hasMore | boolean | yes | Whether more results are available via the cursor. |
| nextCursor | string | – | Cursor to pass to the next list_templates call. |
| templates | array | yes | The matching templates (all fields). |
No examples provided.
render_document Generate Document ~3,384
Generate a document by merging a Carbone template with JSON data. Two modes: (1) pass templateId to use a previously uploaded template; (2) pass template (file path, URL, or base64) to upload and render in a single request without storing a template. Supports output format conversion, multilingual rendering, currency conversion, batch generation, and advanced PDF options (watermark, password, PDF/A). Async mode: pass webhookUrl to render asynchronously — Carbone will POST the renderId to your URL when the document is ready. Async mode is required when using batch generation (batchSplitBy).
| Name | Type | Req | Description |

upload_template Upload Template ~593
Upload and store a reusable Carbone template. Once uploaded, use render_document with the returned Template ID to generate documents from it. Supports versioning: multiple versions can live under a single stable Template ID, with deployedAt controlling which version is active. Accepted formats: DOCX, XLSX, PPTX, ODT, ODS, ODP, ODG, HTML, XHTML, IDML, XML, Markdown, PDF, and more.
| Name | Type | Req | Description |
