SNACS Data
SEC dilution data, live market data, and news for U.S. equities, with point-in-time as-of queries.
What can you do with SNACS Data?
- "Pull the full dilution chain state for TICKER - active shelfs, ATMs, warrants, converts."
- "What was this company's cash, float, and active facilities on 2024-12-31?" (point-in-time, no lookahead bias)
- "Screen for stocks under $5 with an active ATM and less than 6 months of runway."
- "Summarize today's 8-Ks and offering-related news for my watchlist."
Install
Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).
claude mcp add --transport http snacs-data 'https://mcp.snacs.trade/' --header 'Authorization: <Bearer <your SNACS API key (snacs_sk_...)>. Optional: clients supporting MCP OAuth (claude.ai) can connect with no key via the one-click sign-in flow.>'{

SNACS MCP Server
Connect your AI assistant to live SEC dilution forensics, market data, and news for U.S. equities updated in real-time.
https://mcp.snacs.trade - remote MCP server, HTTP transport, no local install.
What you can ask
- "Pull the full dilution chain state for TICKER - active shelfs, ATMs, warrants, converts."
- "What was this company's cash, float, and active facilities on 2024-12-31?" (point-in-time, no lookahead bias)
- "Screen for stocks under $5 with an active ATM and less than 6 months of runway."
- "Summarize today's 8-Ks and offering-related news for my watchlist."
Setup
You need an API key: snacs.trade/api -> subscribe -> account settings -> API keys (snacs_sk_live_...).
On claude.ai (web), no key is needed: Settings -> Connectors -> Add custom connector -> URL https://mcp.snacs.trade (leave the advanced fields empty) -> Connect, then sign in with your SNACS account and approve. The server is an OAuth 2.1 protected resource (PKCE S256, DCR); clients that speak MCP OAuth discover it automatically. API keys keep working everywhere else.
The server accepts the key two ways: Authorization: Bearer snacs_sk_... (shown below) or a plain X-API-Key: snacs_sk_... header (useful for gateways and directories that inject a single key header).
