Overview

Form4API MCP Server

Wraps the Form4API REST service as an MCP server, giving any MCP-compatible AI assistant direct access to real-time US insider trading data from the SEC's EDGAR system.

Example prompts

Once configured, ask your AI assistant questions like:

"What insider trades happened at NVDA this week, excluding 10b5-1 plan trades?"
"Show me cluster buy signals from the last 7 days"
"What is Tim Cook's CIK and how many times has he bought AAPL stock?"
"Pull all open-market purchases over $500K at Tesla in 2026"
"What has the CFO of Microsoft been doing with their shares this year?"
"Check my Form4API usage and plan"

Tools (9)

Tool	Description
`get_transactions`	Search insider transactions — filter by ticker, insider, code, date range,
exclude 10b5-1 plan trades
`get_recent_filings`	Most recent Form 4 filings, optionally filtered by ticker
`get_filing`	Single filing by SEC accession number
`get_insider_profile`	Insider profile — name, title, director / officer / 10% owner flags
`get_insider_transactions`	All transactions for a specific insider by CIK
`get_company_overview`	Company profile — name, CIK, SIC sector, state, website, filing counts
`get_company_insiders`	All insiders who have filed Form 4s for a company
`get_signals`	Cluster buy/sell signals — excludes 10b5-1 plan trades (Business plan+)
`check_usage`	Your API key usage stats — plan, requests today, daily limit

Setup

Get a free API key at form4api.com/dashboard (1,000 requests/day, no credit card).
Add to your MCP client config (Claude Desktop, Cursor, Windsurf, Zed):

{
  "mcpServers": {
    "form4api": {
      "command": "npx",
      "args": ["-y", "form4api-mcp"],
      "env": {
        "FORM4API_KEY": "fapi_live_your_key_here"
      }
    }
  }
}

3. Restart your client. The 9 tools appear automatically.

Features

- Real-time data from SEC EDGAR (10-minute poll cycle)
- Amendment-aware — handles Form 4/A filings correctly (most competitors silently double-count)
- 10b5-1 plan detection — discretionary trades flagged separately from pre-scheduled plan trades
- Cluster signals — fires when 3+ insiders at the same company buy or sell within a 5-day window
- Plan-aware errors — Free users calling get_signals get a clear upgrade message, not a cryptic 402
- 100% public data — sourced from SEC EDGAR; zero proprietary data acquisition cost

Linux Info Mcp

@ranglust

62(and growing) read-only diagnostic tools that let Claude inspect your Linux fleet without touching it. Files, systemd, performance, networking, processes, disks, kernel, packages, Docker — each a hardened wrapper around a command you already trust, run over your own SSH config. Read-only by construction: there is no code path that restarts a service, edits a file, installs a package, or runs anything that mutates state. Every argument is validated and shell-quoted, flag injection is killed by per-tool whitelists, and hosts can be pinned to an allowlist. Point it at production and sleep. Run any tool on one host, or pass a list to fan out in parallel — bounded, with a hard 25-host ceiling so a curious model can't trigger an SSH storm. Why - Can't break anything — no mutate path exists. No restart, no edit, no install, no -exec. - Injection-hardened — shlex.quote everywhere, flag whitelists, NUL/newline rejection, host allowlist. - Your SSH, your rules — uses your ssh/agent or any wrapper (tsh ssh, jump hosts). Server never sees a credential. - Bounded — byte-capped output, per-call timeouts, capped multi-host fan-out. - Auditable — structured {stdout, stderr, exit_code, truncated} + optional JSONL logs with per-call IDs. Setup Python via uv. One mcpServers entry, tuned by env vars. Works with Claude Desktop and Claude Code.
