What is the Octoparse MCP Server?
Connect your Octoparse framework to your AI agent and turn cloud-based web scraping into a fully conversational command center.
What you can do
- Task Execution — Trigger the launch engine using
start_taskwhenever data refresh is needed, or invokestop_taskto halt runaway crawlers instantly. - Status Monitoring — Keep a pulse on active bots by calling
get_task_status, or systematically drill down through your project taxonomy vialist_task_groupsandlist_tasks. - Data Ingestion — Dump the latest extracted web rows natively into the AI's context using
get_task_data, allowing the LLM to format, structure, or summarize the results immediately. - Token Operations — Authenticate dynamically utilizing
get_tokenwith your core credentials.
How it works
- Subscribe to this server
- Enter your Premium Octoparse API Credentials (Username/Email and Password)
- Command your agent (e.g., Claude or Cursor) to spin up scrapers and read the downloaded data directly onto your IDE
Who is this for?
- Data Engineers — trigger scheduled pipelines, check extraction states, and dump JSON samples to debug schemas without leaving your terminal.
- Growth Hackers — quickly spin up an Amazon or LinkedIn scraper, grab the extracted table data, and have the AI formulate email lists simultaneously.
- Business Analysts — fetch the competitive pricing matrices scraped overnight and ask the AI to summarize price drops directly in the conversation.
Built-in capabilities (10)
Done to purge testing footprints before production crawls. Delete all securely stored data for an Octoparse task
Use offset-based pagination strictly to prevent memory crash exceptions (max 1000 limit). Export un-exported data from a completed Octoparse scraping task
Get the current running status of an Octoparse cloud task
0 password grant. Returns an access_token. The access_token must be stored and reused for API calls until expiration. Obtain an OAuth 2.0 access token from Octoparse
Use these IDs to filter executing scraping tasks nested inside a specific folder limit. List all task groups (folders) in the Octoparse account
Each task includes a taskId, status, and creation date. Use the taskId for starting or polling data. List all configured cloud scraping tasks on Octoparse
Execute this immediately after a successful `get_task_data`. Mark all currently stored data in an Octoparse task as extracted
Task changes status to Running instantly. Start a cloud scraping task on Octoparse

Frequently asked questions
Can I have my AI format the scraped JSON into a clean Markdown table?
Absolutely. Because Octoparse MCP connects natively via the get_task_data capability directly into the AI's isolated context window, the language model can instantly translate cumbersome JSON fields into polished, structured, and legible tabular outputs on demand.
Is it possible to track task progress percentage in the chat?
Yes. When you instruct your agent to run get_task_status, it fetches the real-time runtime progress metrics from Octoparse's cloud. You'll see whether it's Waiting, Running, or Completed, along with how many rows have been extracted so far.
Do I need a paid Octoparse plan for API capabilities to work?
Yes. Octoparse explicitly limits their Advanced Cloud APIs strictly to their paid subscription levels. A Free tier account will reject the authentication tokens when attempting to fetch the runtime data.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
