Orbit Sentinel MCP Server

MCP (Model Context Protocol) server for Orbit Sentinel — 418,000+ extracted space regulatory filings from FCC, ITU, UNOOSA, and FAA-AST, queryable from Claude Desktop, Claude Code, Cursor, or any MCP client.

An API key is required. Beta access: https://console.viventine.com.

The server is a thin, open-source (MIT) stdio client of the public REST API — five Go files, easy to audit before you run it.

Install

Homebrew (macOS — recommended)

brew install --cask acaracappa/tap/orbit-sentinel-mcp

Installs to $(brew --prefix)/bin/orbit-sentinel-mcp, handles the quarantine flag for you, and upgrades with brew upgrade.

Manual download

Download the archive for your platform from the latest release, then:

tar -xzf orbit-sentinel-mcp_*.tar.gz
mkdir -p ~/bin && mv orbit-sentinel-mcp ~/bin/

macOS only — the binary is not notarized yet, so clear the quarantine flag once:

xattr -d com.apple.quarantine ~/bin/orbit-sentinel-mcp

Windows: unzip and note the full path to orbit-sentinel-mcp.exe.

Build from source

go install github.com/acaracappa/orbit-sentinel-mcp@latest

Configure

The server reads two environment variables:

| Variable | Purpose | |---|---| | MCP_API_URL | Orbit Sentinel API base URL (https://orbit-sentinel.viventine.com) | | MCP_API_KEY | Your API key from the console |

Claude Desktop — add to ~/Library/Application Support/Claude/claude_desktop_config.json (Windows: %APPDATA%\Claude\claude_desktop_config.json), using the absolute path to the binary (~ is not expanded):

{
  "mcpServers": {
    "orbit-sentinel": {
      "command": "/absolute/path/to/orbit-sentinel-mcp",
      "env": {
        "MCP_API_URL": "https://orbit-sentinel.viventine.com",
        "MCP_API_KEY": "<your-key>"
      }
    }
  }
}

Claude Code — one command:

claude mcp add orbit-sentinel \
  --env MCP_API_URL=https://orbit-sentinel.viventine.com \
  --env MCP_API_KEY=<your-key> \
  -- ~/bin/orbit-sentinel-mcp

Restart your client; the Orbit Sentinel tools (research, search_filings, get_entity_profile, …) appear in the tools menu.

Releasing (maintainers)

Tag and push — GitHub Actions builds and publishes all platforms:

git tag v0.x.y && git push origin v0.x.y

Asset names are version-stable (orbit-sentinel-mcp_<os>_<arch>.tar.gz), so releases/latest/download/... URLs always serve the newest build.
