openfigi-mcp

MCP (Model Context Protocol) server for using OpenFIGI with Claude and other AI assistants.

Terminal

npm install openfigi-mcp

Add to Claude Desktop config:

config.json

{
  "mcpServers": {
    "openfigi": {
      "command": "npx",
      "args": ["openfigi-mcp@latest"],
      "env": {
        "OPENFIGI_API_KEY": "your-api-key-here"
      }
    }
  }
}

Features:

Auto-detection: Parse CSV/text and detect identifier types (ISIN, CUSIP, SEDOL, Bloomberg ID, Ticker)
Batch operations: Process up to 100 identifiers at once
Ticker + Exchange: Supports formats like AAPL US, ABLI SS, VOD LN

Using with Vercel AI SDK

Terminal

npm install ai @ai-sdk/mcp @ai-sdk/anthropic @modelcontextprotocol/sdk

server.ts

import { createMCPClient } from '@ai-sdk/mcp'
import { StdioClientTransport } from '@modelcontextprotocol/sdk/client/stdio.js'
import { generateText } from 'ai'
import { anthropic } from '@ai-sdk/anthropic'

const mcpClient = await createMCPClient({
  transport: new StdioClientTransport({
    command: 'npx',
    args: ['openfigi-mcp'],
    env: { OPENFIGI_API_KEY: process.env.OPENFIGI_API_KEY }
  }),
})

const tools = await mcpClient.tools()

const { text } = await generateText({
  model: anthropic('claude-sonnet-4-20250514'),
  tools,
  maxSteps: 5,
  prompt: 'Find the FIGI for Apple Inc using ISIN US0378331005',
})

await mcpClient.close()

Note: For AI SDK 5.x, use experimental_createMCPClient from 'ai' instead of createMCPClient from '@ai-sdk/mcp'.
