Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "openfigi": {
      "command": "npx",
      "args": [
        "-y",
        "openfigi-mcp"
      ],
      "env": {
        "OPENFIGI_API_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add openfigi --env OPENFIGI_API_KEY=your-value -- npx -y openfigi-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "openfigi": {
      "command": "npx",
      "args": [
        "-y",
        "openfigi-mcp"
      ],
      "env": {
        "OPENFIGI_API_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "openfigi": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "openfigi-mcp"
      ],
      "env": {
        "OPENFIGI_API_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

OPENFIGI_API_KEY secret env
OpenFIGI API key (optional but recommended for higher rate limits)

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Openfigi safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: OPENFIGI_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.4) reached the registry 10 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Search by identifier type: ISIN, CUSIP, SEDOL, Ticker, Bloomberg ID
Auto-detection: Automatically detect identifier types from text/CSV data
Ticker + Exchange: Parse formats like AAPL US, ABLI SS, VOD LN
Batch operations: Process up to 100 identifiers in a single request
Not Found reporting: Clear indicators when identifiers don't exist
Reference resources: Access identifier types, exchange codes, security types

Installation

Using npx (easiest)

No installation required - just configure Claude Desktop:

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

Global Installation

npm install -g openfigi-mcp

"mcpServers": { "openfigi": { "command": "openfigi-mcp", "env": { "OPENFIGI_API_KEY": "your-api-key-here" } } } }

Search Tools

Tool	Description	Example
`search_by_isin`	Search by ISIN	`US0378331005` (Apple)
`search_by_cusip`	Search by CUSIP	`037833100` (Apple)
`search_by_sedol`	Search by SEDOL	`2046251` (Apple)
`search_by_ticker`	Search by ticker (smart search)	`AAPL` with exchCode `US`
`search_by_bloomberg_id`	Search by Bloomberg ID	`BBG000B9XRY4`

Smart Ticker Search

The search_by_ticker tool automatically tries multiple security types when searching, so you don't need to know if a stock is common or preferred:

# These all work automatically:

AAPL US → Common Stock (Apple) VOW3 GY → Preference shares (Volkswagen preferred) P911 GY → Preference shares (Porsche) RR. LN → Common Stock (Rolls-Royce) BA. LN → Common Stock (BAE Systems)

If you need to search for a specific security type, you can use the optional securityType2 parameter:

securityType2	Description
`Common Stock`	Regular common shares
`Preference`	Preferred/preference shares
`Depositary Receipt`	ADRs, GDRs
`ETP`	ETFs and other exchange-traded products

Auto-Detection Tools

Tool	Description
`search_auto_detect`	Auto-detect identifier type and search a single identifier
`parse_identifiers`	Parse CSV/text and detect identifier types (no API call)
`batch_search_auto_detect`	Parse and search multiple identifiers in one request

Utility Tools

Tool	Description
`batch_mapping`	Map up to 100 identifiers with explicit types
`validate_identifier`	Validate identifier format without searching
`get_rate_limit_status`	Check current API rate limit status

Auto-Detection Examples

Tickers with Exchange Codes

The tools recognize the Bloomberg Terminal format TICKER EXCHANGE:

Ticker

ABLI SS ABSO SS AAPL US VOD LN 7203 JP

Common exchange codes:

Code	Exchange
`US`	United States
`SS`	Stockholm (Nasdaq Stockholm)
`LN`	London
`GY`	Germany (Xetra)
`JP`	Japan
`HK`	Hong Kong
`FP`	France (Euronext Paris)

Mixed Identifiers

The tools auto-detect different identifier types:

US0378331005      → ISIN [high confidence]

BBG000B9XRY4 → Bloomberg ID [high confidence] AAPL US → Ticker with exchange [high confidence] 037833100 → CUSIP [medium confidence] 2046251 → SEDOL [medium confidence] AAPL → Ticker [low confidence]

Not Found Handling

When identifiers don't exist in OpenFIGI, the output clearly indicates:

Single search:

Detected type: TICKER (Exchange: SS) [high confidence]

⚠️ NOT FOUND: "BLABLABLA" on exchange SS returned no results.

No results found

Batch search:

Detected 3 identifiers:

Ticker: 3

[1] TICKER: AAPL [US] Result 1: FIGI: BBG000B9XRY4 Name: APPLE INC ...

[2] TICKER: INVALID [SS] ⚠️ NOT FOUND No results found

[3] TICKER: MSFT [US] Result 1: FIGI: BBG000BPH459 ...
