Overview

AI-generated overview

Hosted Extend MCP server that lets an assistant parse, extract, classify, split and fill PDF forms from unstructured documents.

What you can do
  • Parse PDFs, images, Office files and spreadsheets into structured data
  • Extract fields, classify documents and split them into parts
  • Fill and edit PDF forms
  • Run multi-step document workflows and manage files and webhooks
  • Run evaluations and consult guidance for writing Extend API or CLI integration code
When to use it
Useful when an assistant needs to turn batches of real-world documents into structured, machine-readable data, or to build and check document-processing pipelines against the Extend platform.
Requirements
Remote Streamable HTTP endpoint at mcp.extend.ai; no local package. OAuth sign-in is required, and the browser flow asks which workspace and environment the connection may use. Network access to Extend's servers.
Before you install
The server calls the Extend API on your behalf under the workspace and environment approved at sign-in, so documents you send are processed by a third party. It can create and change files, workflows and webhooks in that workspace. Review Extend's privacy policy, terms and security overview before connecting.

Installation

In SourceWeft

  1. Open Extend in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/ai.extend%2Fextend/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

Extend Agent Plugin

[smithery badge]

Document processing for agents, packaged as a plugin. Extend turns unstructured documents (PDFs, images, Office files, spreadsheets) into structured data: parsing, field extraction, classification, splitting, PDF form filling, and multi-step document workflows.

This plugin bundles:

  • The hosted Extend MCP server (https://mcp.extend.ai/mcp): 80+ tools covering extraction, parsing, classification, splitting, PDF editing, workflows, files, webhooks, and evaluations. Sign-in is OAuth: your client opens a browser window where you choose the workspace and environment the connection may use. The server teaches its own cross-tool usage patterns through MCP server instructions and per-response guidance, so no companion skill is needed for it.
  • extend-api skill: a compact brief for agents writing integration code against the Extend API and SDKs: endpoints, schema rules, sync-vs-async patterns, webhooks, and error handling.
  • extend-cli skill: how to drive the extend CLI for shell, script, and CI work against local files.

The skills also install standalone, without the plugin:

bash
npx skills add extend-hq/extend-agent-plugin

Install

  • Cursor: install "Extend" from the Cursor Marketplace, or load this repository from ~/.cursor/plugins/local/ for development.
  • Claude Code: claude plugin install extend once listed in the plugin directory, or add this repository as a plugin marketplace.
  • Any MCP client: you don't need the plugin to use Extend; connect directly to https://mcp.extend.ai/mcp (Streamable HTTP + OAuth). See the connection guide for per-client instructions.
