Orbit Sentinel

The server is a thin, open-source (MIT) client of the public REST API — nine Go files, easy to audit before you run it. Run it locally over stdio, or skip the install entirely and point your client at the hosted remote endpoint (below).

The lowest-friction path — no binary, no updates. Point any HTTP-capable MCP client at:

https://orbit-sentinel.viventine.com/mcp

Transport is Streamable HTTP (stateless). Two ways to authenticate:

claude mcp add --transport http orbit-sentinel https://orbit-sentinel.viventine.com/mcp

API key— if you'd rather use a static key (or your client can't do OAuth), pass your console key as a bearer token:

claude mcp add --transport http orbit-sentinel \ https://orbit-sentinel.viventine.com/mcp \ --header "Authorization: Bearer <your-key>"

Generic MCP clients— any Streamable HTTP client works via OAuth 2.1 (RFC 9728 protected-resource discovery) or anAuthorization: Bearer <key>header. For a stdio-only client, bridge withnpx mcp-remote https://orbit-sentinel.viventine.com/mcp.

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 withbrew upgrade.

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 toorbit-sentinel-mcp.exe.

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

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 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.

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), soreleases/latest/download/...URLs always serve the newest build.

The Claude Desktop bundle (orbit-sentinel-mcp.mcpb) is packed and uploaded by the release workflow — the manifest template lives atmcpb/manifest.json(itsversionis stamped from the tag at pack time).
