Overview

AI-generated overview

SignalStack is a remote MCP server that gives an assistant a daily 0-100 crypto market score, with category breakdowns and history.

What you can do
  • Read today's composite Candle Review score and its label
  • Retrieve historical daily reviews, up to a chosen limit
  • Fetch a per-category breakdown (price action, on-chain, derivatives, ETF flows, macro, dominance, sentiment) on the paid tier
When to use it
Useful when an assistant needs a quick, pre-computed read on overall crypto market conditions, or a short history of daily scores, rather than raw market data.
Requirements
A remote SSE endpoint; no local install. The free tier needs no key. The category breakdown requires an X-API-Key header on the connection, obtained by contacting the provider or through its RapidAPI listing.
Before you install
Pro access depends on a paid API key passed as X-API-Key; the README lists Stripe billing as planned. Scores are third-party opinions derived from DefiLlama, CoinGecko and Dune data, updated about once a day, and are not investment advice. The README documents the endpoint over plain HTTP.

Installation

In SourceWeft

  1. Open SignalStack in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via SSE. 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.ud4090v%2Fsignalstack-mcp/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.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.
