Overview

What is subspace-api?

subspace-api is an Express-based RESTful API and stateless Model Context Protocol (MCP) server. It integrates with weather alerts (NWS), real-time stock quotes (yahoo-finance2), DC Metro transit data (WMATA), live flight tracking (AeroDataBox), and Discord activities. It is designed for developers and system integrators building AI agent tools that require live data from these sources.

How to use subspace-api?

Install via Docker Compose (docker compose build && docker compose up -d) or by manually running npm run build && npm run start. Configure required environment variables (OAuth client credentials, auth server URL, MCP server URL) and optional ones for TRMNL plugins and Discord activity. The server then exposes MCP tools over HTTP secured with OAuth 2.0 bearer tokens.

Key features of subspace-api

  • Stateless MCP server secured with OAuth 2.0 bearer tokens
  • Real-time stock quotes via yahoo-finance2
  • NWS weather alerts and forecasts as MCP tools
  • DC Metro rail incidents and arrival predictions
  • Live flight status via AeroDataBox with TRMNL plugin support
  • Discord OAuth token exchange endpoint for activities

Use cases of subspace-api

  • AI agents querying live weather alerts for operational decision-making
  • Automated stock price retrieval for financial analysis tools
  • Monitoring DC Metro rail status in transit or navigation apps
  • Displaying live flight status on TRMNL e-ink devices
  • Integrating Discord activity authentication with OAuth token exchange

Frequently asked questions

1

What is the difference between the hosted version and self-hosted?

The hosted version requires abiding by the Terms of Service (TOS). If you self-host the code under the GNU GPLv3 license, the TOS does not apply.

2

What are the runtime dependencies?

Node.js and npm for manual builds, or Docker with Docker Compose. External APIs require their own API keys (WMATA, AeroDataBox, etc.) as configured via environment variables.

3

Where does the data come from?

Data is fetched live from external APIs: NWS for weather, yahoo-finance2 for stocks, WMATA for DC Metro, and AeroDataBox (via RapidAPI) for flights. The server itself stores no persistent data.

4

What transport and authentication does the MCP server use?

The MCP server runs over HTTP and uses OAuth 2.0 bearer token authentication. Tokens are validated via token introspection against a Keycloak-compatible identity provider.

5

Are there any known limitations?

The README does not list specific limitations, but notes that the Discord activity endpoint is deprecated. No other constraints are stated.
