Orbit Sentinel MCP Server

MCP (Model Context Protocol) server for Orbit Sentinel — 419,000+ 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

Claude Desktop (one-click)

Download orbit-sentinel-mcp.mcpb and double-click it — Claude Desktop installs the extension and prompts for your API key. Bundles macOS (universal), Linux, and Windows binaries.

Homebrew (macOS — recommended)

brew install --cask viventine-space/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/viventine-space/orbit-sentinel-mcp@latest

Configure

The server reads two environment variables:

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.

Also rebuild and upload the Claude Desktop bundle so the releases/latest one-click link stays valid: rebuild the three platform binaries into the MCPB layout, mcpb pack, then gh release upload v0.x.y orbit-sentinel-mcp.mcpb (candidate for goreleaser automation next cycle).

Then repeat the Glama release — it does not auto-update from GitHub, and it gates the quality score on the badge above. On the Dockerfile admin page, the saved build spec should carry over (build steps install Go and go build; placeholder parameters need a dummy MCP_API_KEY to satisfy the env schema) — click Build, then Make Release with the new version. Manual for now; consider Glama API integration next release cycle.
