fmp-stable-api 2.0.0

Financial Modeling Prep API client — auto-updating endpoints, GUI, and MCP server

fmp-stable-api

Financial Modeling Prep API client — auto-updating endpoints, GUI manager, and optional MCP server.

Install

pip install fmp-stable-api           # API client + GUI
pip install fmp-stable-api[mcp]      # also includes the MCP server

Quick start

from fmp_stable_api import FMP

client = FMP(client_type="Premium", client_key="your_api_key")

# Dynamic endpoint access — categories and endpoints loaded from fmp_endpoints.json
results = client.Search.search_symbol(symbol="AAPL")

# Raw URL request
data = client.request("https://financialmodelingprep.com/stable/profile", {"symbol": "AAPL"})

# Show all available categories
client.help()

# Show endpoints in a category
client.Search.help()

Endpoints auto-update

On first use and once every 24 hours, the client fetches the latest fmp_endpoints.json from GitHub and caches it at ~/.fmp/fmp_endpoints.json. A bundled fallback is used when the network is unavailable.

# Force an immediate refresh
from fmp_stable_api import update_endpoints
update_endpoints(force=True)

# Or via the client
client.update_endpoints(force=True)

GUI manager

A tkinter-based GUI for browsing and editing fmp_endpoints.json:

fmp-gui

MCP server (Claude Desktop / AI assistants)

pip install fmp[mcp]

Add to your Claude Desktop claude_desktop_config.json:

{
  "mcpServers": {
    "fmp": {
      "command": "fmp-mcp",
      "env": {
        "FMP_API_KEY": "your_api_key_here",
        "FMP_CLIENT_TYPE": "Premium"
      }
    }
  }
}

Tools are named {Category}__{endpoint}, e.g. Search__search_symbol.

Cache files

~/.fmp/api_keys.json	GUI API key storage

Security

API Keys:

• Never commit API keys to git. The GUI stores keys in ~/.fmp/api_keys.json automatically.
• If you had an API key in a config file that was committed to a git repository, rotate it immediately in your FMP account dashboard. Treat any committed key as compromised.
• Do not share ~/.fmp/api_keys.json.

Endpoint Updates:

• Downloaded fmp_endpoints.json is validated to ensure stable_url stays on financialmodelingprep.com. Tampered configs with off-domain base URLs are rejected.
