Jarvis Market Signals
io.github.CasterdlyPublished by GitHub account Casterdlyv0.1.0Updated Oct 24, 2026
Live crypto market signals for AI agents: perp liquidations, funding, OI positioning, yield, FX.
The publisher's own server: SIGNALS Loyalty Agent Platform
Overview
Remote MCP endpoint serving live crypto-derivatives market signals — perp liquidations, funding rates, open-interest positioning, stablecoin yields and FX…
- What you can do
- Summarize market-wide perp liquidations over a recent window, with long vs short notional and top coins
- Inspect a single coin's liquidations, including the largest individual prints
- Read current perp funding rates and surface the most stretched ones
- Judge whether leveraged positioning is building or unwinding from open-interest change, funding crowding and liquidation side
- Rank safe single-asset stablecoin lending yields and compare holding versus deploying against a T-bill floor
- Convert fiat currencies at live ECB reference rates
- When to use it
- Useful when an assistant needs current crypto-derivatives context that a static model cannot know: liquidation cascades, funding crowding, positioning shifts, stablecoin yield comparisons, or exact FX conversion. It is informational market data, not trading execution.
- Requirements
- A remote streamable HTTP endpoint; no local install. Tool calls need a bearer key in the Authorization header, obtained free by opening a GitHub issue; the free tier allows 100 calls per day. Discovery calls (initialize, tools/list) work without a key. Network access to the endpoint is required.
Installation
In SourceWeft
- Open Jarvis Market Signals in the dashboard and add it to a workspace.
- Connect Authorization token credentials. They are stored privately and never shown on public pages.
- Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.Casterdly%2Fjarvis-market-signals/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Other MCP clients
Add this to your client's mcpServers config.

Jarvis Market Signals — MCP server
Live crypto-derivatives and market signals for AI agents: perp liquidations, funding-rate crowding, open-interest positioning, safe stablecoin yield, and FX — fresh streaming data a static model can't know, served over a metered MCP endpoint.
Endpoint: https://jarvis.tail12fa6b.ts.net:8443/mcp (streamable HTTP)
Free tier: 100 calls/day — open an issue to get a key.
Discovery is open: initialize and tools/list need no key, so any MCP client or registry scanner can inspect the tools before authenticating.
Tools
Liquidation and positioning tools query a rolling 24-hour buffer fed by always-on ingesters; window_minutes is capped to that buffer.
Quick start
Claude Code
Cursor / generic MCP client config
curl (no key needed for discovery)
tools/call requires Authorization: Bearer <key> (or x-api-key). Without one you get a plain JSON 401.
Auth and limits
- Anonymous:
initialize,tools/list— open for discovery. - Keyed:
tools/call—Authorization: Bearer jvk_…, free tier 100 calls/day (rolling 24h), HTTP 429 over quota. - No OAuth; keys are issued manually via GitHub issue while the service is small.
Notes
- Market data is informational only — not financial advice. Yield figures are estimates from public feeds; verify before acting.
- The server runs on dedicated home infrastructure behind a Tailscale Funnel TLS relay; brief maintenance windows can occur.
- Source for the gateway lives in a private repo; this repo is the public listing, key-request channel, and issue tracker.
