AI Agent Integration

MCP Server for AI Coding Agents

The official cas-parser-node-mcp package turns your AI coding agent into a portfolio data expert. 17 live API tools auto-generated from our OpenAPI spec. Claude, Cursor, Windsurf, and Codeium can parse CAS PDFs, fetch CDSL holdings, import from Gmail, and more.

What Your AI Agent Gets

Parse Any CAS

CDSL, NSDL, CAMS, KFintech. Auto-detect type, extract JSON

CDSL OTP Fetch

2-step OTP flow to pull real-time demat holdings from CDSL

Gmail Import

OAuth flow + list CAS files from user's Gmail inbox

Code Mode

Agent writes TypeScript code that runs in a sandboxed runtime

Claude Code (Recommended)

1 command

claude mcp add cas_parser_node_mcp \
  -e CAS_PARSER_API_KEY=your-api-key \
  -- npx -y cas-parser-node-mcp@latest

Use sandbox-with-json-responses for testing without an API key.

Cursor / Windsurf / Codeium

mcp.json

{
  "mcpServers": {
    "cas_parser_node_mcp": {
      "command": "npx",
      "args": ["-y", "cas-parser-node-mcp@latest"],
      "env": { "CAS_PARSER_API_KEY": "your-key" }
    }
  }

Agents Can Sign Up Too

Your agent can obtain an API key without you leaving the terminal. No copy-paste needed.

Agent generates a one-time URL

No API call needed — the token is created locally

You open the URL and approve

Agent gets the key automatically

Polls a single endpoint, writes to .env, done

# Agent generates a token and asks you to open a URL
TOKEN=$(openssl rand -hex 32)
echo "Open https://app.casparser.in/agent-auth?token=${TOKEN}"

# Agent polls until you approve
curl -s https://api.casparser.in/v1/agent-auth/token/${TOKEN}
# → {"status": "approved", "api_key": "sk_...", "email": "..."}

Works with any agent that can run shell commands. No SDK or CLI required.
