## Introduction

### How to connect PDF Vector MCP with ChatGPT Work
[ChatGPT Work](https://openai.com/chatgpt-work/) is an agent inside ChatGPT built for your most ambitious work. It takes action across your apps and files, stays with a project for hours, and turns a goal into finished materials like sheets, slides, and docs - not just answers.
In this guide, I will explain the easiest and most secure way to connect your PDF Vector account to ChatGPT Work via Composio Connect, so it can parse PDFs into markdown, extract structured data, answer document questions, index academic papers, and search grants through natural language commands without ever putting your account credentials at risk.

## TL;DR

### Why use Composio over default connectors?
- Apps with read and write access. Default connectors mostly can read your data. Composio's PDF Vector integration lets ChatGPT Work take actions like creating drafts, sending updates, labeling records, and more.
- 1,500+ SaaS toolkits out of the box. Composio gives you instant access to a vast catalog of pre-built connectors, from Gmail and Slack to Notion, Linear, and Salesforce.
- One MCP server for every app. Connect any of your applications on demand through a single endpoint, rather than juggling a separate server for each app.
- Smart, context-aware tool loading. Unlike traditional MCP servers that dump every available tool into the LLM context window, Composio searches for and loads only the tools relevant to the task at hand.
- Cross-app automation. Chain actions across multiple apps in a single run - fetch a thread, summarize it in Notion, and post highlights to Slack without leaving the conversation.

## Connect PDF Vector to ChatGPT Work

### Prerequisites
- A ChatGPT account with access to ChatGPT Work (rolling out across Pro, Enterprise, Edu, Plus, and Business plans). We will use the [ChatGPT desktop app](https://openai.com/chatgpt/download/), which is available on every plan.
- Access to the PDF Vector workspace you want to connect.
- [Composio MCP](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=chatgpt&utm_content=composio_connect&next=%2F~%2Forg%2Fconnect%2Fclients%2Fchatgpt).
Note: Composio connects through OAuth. You will be asked to sign in and approve specific permissions. Review the permission screen carefully if you are using a work account.
### Step-by-step: Connect PDF Vector to ChatGPT Work
### 1. Open the MCP settings
In ChatGPT Work, go to Settings and open the Plugins section. Inside the Plugins page, click the MCP tab.
### 2. Add the server
Click Add server. In the Name field enter Composio, for Type select Streamable HTTP, and in the URL field paste the Composio MCP server URL:

```bash
https://connect.composio.dev/mcp
```

## What is the PDF Vector MCP server, and what's possible with it?

The PDF Vector MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your PDF Vector account. It provides structured and secure access so your agent can perform PDF Vector operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `PDF_VECTOR_ASK_DOCUMENT` | Ask Document | Answer one question from a general, identity, invoice, or bank-statement document. Processing consumes credits; the response reports the actual model and credit cost. The tool never retries with a higher model automatically. |
| `PDF_VECTOR_EXTRACT_DOCUMENT` | Extract Document Data | Extract schema-constrained structured data from a general, identity, invoice, or bank-statement document. Processing consumes credits and never retries with a higher model automatically. |

| `PDF_VECTOR_FIND_CITATIONS` | Find Citations | Find relevant academic citations for each sentence in a paragraph and preserve provider-specific partial errors. |
| `PDF_VECTOR_FIND_SIMILAR_PAPERS` | Find Similar Papers | Find papers related to a seed publication using citation-network similarity, optionally including relationship edges. |
| `PDF_VECTOR_GET_PAPER_GRAPH` | Get Paper Graph | Retrieve a publication plus one independently offset-controlled page of citing papers and one page of referenced papers. |
| `PDF_VECTOR_PARSE_ACADEMIC_PAPER` | Parse Academic Paper | Resolve an academic identifier or provider URL to a public PDF and parse it to markdown. Processing consumes credits, returns the actual model and credit cost, and never retries with a higher model automatically. |
| `PDF_VECTOR_PARSE_DOCUMENT` | Parse Document | Convert a general, identity, invoice, or bank-statement document to markdown. Processing consumes credits; returns the actual model and credit cost and never retries with a higher model automatically. |
| `PDF_VECTOR_SEARCH_PUBLICATIONS` | Search Publications | Search academic publications across selected databases and return one offset-controlled page, including any provider-specific partial errors. |
| `PDF_VECTOR_SEARCH_RESEARCH_GRANTS` | Search Research Grants | Search US, EU, and UK research-grant providers and return one explicit offset-controlled page with partial provider errors. |

## Frequently Asked Questions

### What are the differences in Tool Router MCP and PDF Vector MCP?

With a standalone PDF Vector MCP server, the agents and LLMs can only access a fixed set of PDF Vector tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from PDF Vector and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with ChatGPT Work?

Yes, you can. ChatGPT Work 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 PDF Vector tools.

### Can I manage the permissions and scopes for PDF Vector while using Tool Router?

Yes, absolutely. You can configure which PDF Vector 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 PDF Vector data and credentials are handled as safely as possible.
