Compatible with every major AI agent and IDE
What is the Portfolio CSV Analyzer MCP Server?
When you export your trading history from DEGIRO, XTB, or Interactive Brokers, you get a massive CSV file with thousands of rows. If you upload this directly to Claude, it will exhaust its context window, hallucinate data, and eventually crash.
This MCP acts as your local AI data scientist. It uses a high-speed streaming CSV parser to process the file line-by-line entirely local. Instead of dumping everything into the chat, it intelligently extracts the column headers and a small representative sample. This provides the AI with the exact schema it needs without overwhelming it. The AI can then guide you to write specific aggregation scripts or understand your portfolio safely.
The Superpowers
- 100% Local Processing: Your entire financial trading history is read locally.
- Massive File Support: Streams CSV files of any size without crashing Node.js or your AI.
- Smart Schema Extraction: Automatically detects column headers, separators, and data types.
- Assistant Ready: Ask the AI: 'Based on this broker export schema, what columns are available for calculating my P&L?'
Built-in capabilities (1)
Provide the absolute file path. Parse massive CSV exports from brokers (DEGIRO, XTB, Trading212) locally. Streams the file to prevent RAM crashes and returns column schemas and sample data

Frequently asked questions
Will it send my entire trading history to the AI?
No! To protect your privacy and prevent context crashes, it only sends the column headers (the schema), the total row count, and a tiny 20-row sample to the AI.
What brokers does this work with?
It works with ANY standard CSV file. Whether it's from DEGIRO, Interactive Brokers, Robinhood, or Trading212, this engine will parse the schema dynamically.
Can it calculate live market P&L?
This specific tool focuses purely on parsing the historical CSV data local. For live market prices, a separate API MCP (like Yahoo Finance) would be needed.
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.
