About
Extend document processing for agents: plugin bundling the hosted Extend MCP server with platform and CLI skills (Agent Plugins + Claude plugin formats)
README
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-apiskill: 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-cliskill: how to drive the extend CLI for shell, script, and CI work against local files.
The skills also install standalone, without the plugin:
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 extendonce 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.
Repository layout
Two manifest formats coexist so one repository serves both ecosystems:
| Path | Purpose |
|---|---|
plugin.json, mcp.json |
Agent Plugins standard (Cursor and other conformant clients) |
.claude-plugin/plugin.json, .mcp.json |
Claude plugin manifest |
skills/ |
Agent Skills shared by both formats |
