Overview

AI-generated overview

Signalcrest is a remote MCP server that gives an assistant ranked technology trend signals and entity momentum scored every 30 minutes across ten developer…

What you can do
  • List top technology signals ranked by current momentum across ten developer and builder communities
  • Read one topic's full detail, score history, cross-source corroboration and lifecycle stage by id
  • List trending entities such as products, companies, libraries and technologies ranked by cross-source momentum
  • Read one entity's composite score, score history, contributing communities and the member items behind the score
When to use it
Useful when you want to know what is gaining traction in developer and builder communities before it becomes obvious, or to trace how a specific technology, library or company has trended over time across sources.
Requirements
A remote endpoint at signalcrest.app over streamable HTTP; a Signalcrest API key sent as a bearer token in the Authorization header. Free accounts are limited to 100 requests a month.
Before you install
The API key is a secret sent in the Authorization header; keep it out of shared logs and prompts. Requests count against a monthly quota on free accounts, so heavy polling can exhaust it. Trend scores are third-party aggregates of public community activity and should be treated as signals, not verified facts.

Installation

In SourceWeft

  1. Open Signalcrest in the dashboard and add it to a workspace.
  2. Connect Authorization token credentials. They are stored privately and never shown on public pages.
  3. 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.apolloprojectsllc-svg%2Fsignalcrest/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

Tools

list_signals

List live signals

Top technology signals ranked by momentum right now, scored every 30 minutes across ten developer and builder communities (Hacker News, GitHub, Stack Overflow, npm, Hugging Face, Dev.to, Lobsters, Product Hunt, arXiv, crypto governance forums). Call this to find what is gaining traction before it reaches search-trend tools — e.g. when the user asks what is emerging, trending, or worth paying attention to in a technology area. Returns live unredacted data with no delay.

Parameterslimitcategory

get_topic

Get topic detail

Full detail and complete score history for one topic, by id (e.g. "hn:48910545", "gh:1287845516"). Call this after list_signals to see how a specific signal has moved over time, its cross-source corroboration, and its lifecycle stage. Ids come from list_signals.

Parametersidrequired

list_entities

List trending entities

Trending entities (products, companies, libraries, technologies) ranked by cross-source momentum. An entity aggregates every post, repo and release mentioning it across ten developer and builder communities — one row per trend rather than per post. Prefer this over list_signals when the user asks about trends or technologies; use list_signals for individual posts.

Parameterslimitcategory

get_entity

Get entity detail

Full detail for one entity by name (e.g. "kubernetes"): current composite score, complete score history, which communities are talking about it, and the live member items (evidence) behind the score. Names come from list_entities.

Score

83% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
