# How to connect Api2pdf to Claude ```json { "title": "How to connect Api2pdf to Claude", "toolkit": "Api2pdf", "toolkit_slug": "api2pdf", "framework": "Claude Cowork", "framework_slug": "claude-cowork", "url": "https://composio.dev/toolkits/api2pdf/framework/claude-cowork", "markdown_url": "https://composio.dev/toolkits/api2pdf/framework/claude-cowork.md", "updated_at": "2026-10-04T17:19:33.367Z" } ``` ## Introduction Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf. This guide walks you through the easiest and most secure way to connect your Api2pdf account to Claude via Composio Connect, enabling it to merge monthly invoices into one PDF, extract specific pages from a large PDF, add custom header and footer to document, and more such actions on your behalf without compromising your account security. Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three. ## Also integrate Api2pdf with - [Claude Code](https://composio.dev/toolkits/api2pdf/framework/claude-code) - [OpenAI Agents SDK](https://composio.dev/toolkits/api2pdf/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/api2pdf/framework/claude-agents-sdk) - [Codex](https://composio.dev/toolkits/api2pdf/framework/codex) - [OpenClaw](https://composio.dev/toolkits/api2pdf/framework/openclaw) - [Hermes](https://composio.dev/toolkits/api2pdf/framework/hermes-agent) - [Atomic Agent](https://composio.dev/toolkits/api2pdf/framework/atomic-agent) - [Google ADK](https://composio.dev/toolkits/api2pdf/framework/google-adk) - [LangChain](https://composio.dev/toolkits/api2pdf/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/api2pdf/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/api2pdf/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/api2pdf/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/api2pdf/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/api2pdf/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/api2pdf/framework/autogen) ## Connect Api2pdf to Claude Cowork ### Connecting Api2pdf to Claude Web, Desktop, and Cowork Two ways to add the Composio connector. Pick whichever you prefer. ### 1. Add with one click Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2. [Add to Claude](https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=Composio&connectorUrl=https%3A%2F%2Fconnect.composio.dev%2Fmcp) ### Add manually In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top. Click Add custom connector and paste in the Composio MCP server URL: ```bash https://connect.composio.dev/mcp ``` ## What is the Api2pdf MCP server, and what's possible with it? The API2PDF MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your API2PDF account. It provides structured and secure access to PDF and document processing tools, so your agent can create PDFs with headers and footers, merge documents, rearrange pages, reduce file sizes, and generate barcodes or QR codes on your behalf. - PDF creation and customization: Have your agent convert HTML into a PDF with customizable headers and footers using Headless Chrome. - Document assembly and page control: Direct your agent to merge multiple PDFs, extract selected pages, or reorder pages into a new sequence. - PDF optimization and conversion: Let the agent reduce a PDF's file size or convert a PDF document into HTML using LibreOffice. - Document thumbnail generation: Instruct your agent to create a thumbnail image from a document using LibreOffice. - Barcode and QR code creation: Have your agent generate barcodes or QR codes for labels, documents, and other workflows. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `API2PDF_ADD_HEADER_FOOTER` | Add Header Footer | Convert HTML to PDF with customizable headers and footers using Headless Chrome. Use for generating reports, invoices, or documents with consistent page numbering, titles, dates, or branding on every page. | | `API2PDF_CHECK_STATUS` | Check API Status | Tool to check the health status of the API2PDF service. Use when you need to verify if the API is available and responding. This endpoint does not require authentication and returns a simple status indicator. | | `API2PDF_DELETE_PDF` | Delete PDF | Delete a previously generated PDF from API2PDF storage by its response ID. By default, API2PDF automatically deletes PDFs after 24 hours. Use this tool when you need to immediately remove a PDF for security or cleanup purposes. The response_id parameter is the ResponseId returned from any PDF generation operation (e.g., merge, convert HTML to PDF, etc.). | | `API2PDF_EXTRACT_PAGES` | Extract PDF Pages | Tool to extract specific pages from a PDF document. Use when you need only certain pages from a larger PDF file. Provide a URL to the source PDF and optionally a page range (0-indexed, end exclusive). Returns a URL to the extracted PDF. | | `API2PDF_LIBREOFFICE_PDF_TO_HTML` | LibreOffice PDF to HTML | Tool to convert a PDF document to HTML using LibreOffice. Use when you need HTML output of a PDF file (experimental; images may be excluded). | | `API2PDF_LIBREOFFICE_THUMBNAIL` | LibreOffice Thumbnail | Tool to generate a thumbnail image of a document using LibreOffice. Use when you need a quick visual preview of a PDF or Office file's first page. | | `API2PDF_MERGE_PDFS` | Merge PDFs | Merge multiple PDF documents into a single PDF file. Provide a list of publicly accessible PDF URLs, and they will be combined in the order specified. The merged PDF is available via a download URL for 24 hours. | | `API2PDF_OPTIMIZE_PDF` | Optimize PDF | Tool to optimize a PDF document to reduce file size while maintaining quality. Use when you need to minimize storage or bandwidth for an existing PDF. | | `API2PDF_REORDER_PAGES` | Reorder PDF Pages | Reorder pages of a PDF document by specifying a new page sequence. Provide a URL to the source PDF and a list of zero-based page indices in the desired order. For example, to reverse a 3-page PDF, use pages=[2,1,0]. The reordered PDF is available via a download URL for 24 hours. | | `API2PDF_ZEBRA_GENERATE_BARCODE` | Generate Barcode or QR Code | Tool to generate barcodes or QR codes using Zebra Crossing (ZXING). Use when you need a barcode or QR code image from text values. | ## Supported Triggers None listed. ## Troubleshooting ### 1. Why does Claude not use the Composio connector for Api2pdf? The connector can show as connected, but Claude must use it in each Api2pdf conversation. - Click + at the lower left of the chat, or type /. - Hover Connectors. - Turn on Composio. - Ask Claude to connect to Api2pdf again. ### 2. Why does Claude show an MCP server error before Api2pdf connects? Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Api2pdf. - Check that the connector URL is https://connect.composio.dev/mcp. - Connectors run from Anthropic's cloud, so your device network is usually not the problem. - Add the connector again from Customize > Connectors, then ask Claude to connect Api2pdf. - If it fails again, send the error and the ofid_ reference id to support@composio.dev. ### 3. Why does the Api2pdf authorization link not work? The Composio connector is one server. Your Api2pdf account connects separately when Claude asks for it. - If the browser does not open, or the link expires, ask Claude to retry the Api2pdf connection. - Composio creates a fresh Api2pdf authorization link. - Open that link in your browser and finish the Api2pdf sign-in. ### 4. Why do Api2pdf actions fail after they worked before? The Api2pdf connection can expire or lose permission. - Ask Claude to inspect the Api2pdf connection. - If the connection is unhealthy, disconnect it when Claude prompts you. - Reconnect the Api2pdf account and retry the action. - If Claude shows a permission prompt, approve it before Claude changes data in Api2pdf. - If the action still fails with a permission error, check that the connected account has that permission in Api2pdf itself. ### 5. How do I switch to a different Api2pdf account? Claude can manage the Api2pdf connection for you. - Ask Claude to disconnect or delete the current Api2pdf account. - Ask Claude to connect Api2pdf again. - Open the new Composio authorization link for Api2pdf. - Sign in with the other Api2pdf account in the browser. - After the account connects, ask Claude to retry the Api2pdf task. ### 6. Why is my Api2pdf connection missing in Claude Desktop or on a Team plan? The connector belongs to your Claude account, so your Api2pdf connection works in Claude Web, Desktop, and Cowork. - In Claude Desktop, open Customize > Connectors. - Next to Composio, click ⋮ and click Clear cache. - If Api2pdf tools still do not appear, click ⋮, disconnect, remove the connector, and add it again. - On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Api2pdf. ## Creating MCP Server - Stand-alone vs Composio SDK The Api2pdf MCP server connects Claude Web, Desktop, and Cowork to your Api2pdf account through Composio. Once connected, Claude can use the available Api2pdf tools and triggers to complete tasks on your behalf. ## Complete Code None listed. ## How to build Api2pdf MCP Agent with another framework - [Claude Code](https://composio.dev/toolkits/api2pdf/framework/claude-code) - [OpenAI Agents SDK](https://composio.dev/toolkits/api2pdf/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/api2pdf/framework/claude-agents-sdk) - [Codex](https://composio.dev/toolkits/api2pdf/framework/codex) - [OpenClaw](https://composio.dev/toolkits/api2pdf/framework/openclaw) - [Hermes](https://composio.dev/toolkits/api2pdf/framework/hermes-agent) - [Atomic Agent](https://composio.dev/toolkits/api2pdf/framework/atomic-agent) - [Google ADK](https://composio.dev/toolkits/api2pdf/framework/google-adk) - [LangChain](https://composio.dev/toolkits/api2pdf/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/api2pdf/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/api2pdf/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/api2pdf/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/api2pdf/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/api2pdf/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/api2pdf/framework/autogen) ## Related Toolkits - [Google Drive](https://composio.dev/toolkits/googledrive) - Google Drive is a cloud storage platform for uploading, sharing, and collaborating on files.

With a standalone Api2pdf MCP server, the agents and LLMs can only access a fixed set of Api2pdf tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Api2pdf and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Claude Cowork? Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Api2pdf tools. ### Can I manage the permissions and scopes for Api2pdf while using Tool Router? Yes, absolutely. You can configure which Api2pdf scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Api2pdf data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
