Overview

AI-generated overview

Remote MCP endpoint that answers one call with aggregated news, finance and AI source data instead of crawling 29 sources mid-task.

What you can do
  • Fetch aggregated results from many news, finance and AI sources in a single query rather than crawling each source separately.
  • Reads are open and require no key, so an assistant can query the endpoint directly.
  • The repository is a publication anchor for a design paper on a portable work record for agents; it contains no implementation code and reports no results.
  • No individual tools are listed in the manifest, so the exact call surface is not documented here.
When to use it
Useful when an assistant needs quick, broad coverage of news, finance and AI sources during a task and you want to avoid building or running your own crawler. The free tier is stated as 100 queries per day.
Requirements
A remote Streamable HTTP endpoint at the provider's domain; no packages, environment variables or headers are declared. Reads are described as open with no key required. Network access to the provider is needed.
Before you install
The README states the repository holds no implementation code and that the design paper reports no results; it also names unimplemented boundaries including sybil resistance, collusion detection, external identity verification, prompt-injection mitigation and dispute governance. Queries and any submitted data go to a third-party service hosted by the project. Free usage is limited to 100 queries per day.

Installation

In SourceWeft

  1. Open QY-Stream Data Server in the dashboard and add it to a workspace.
  2. 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/ltd.qianyuan%2Fqy-stream/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

README

Qian Yuan — portable work record for agents

This repository is a publication anchor. It contains no implementation code yet.

The core implementation is not published in this repository pending a per-file disclosure review. What is here is the citable record of the design.

Design paper

Toward a Portable Work Record for Agents: A Design for Identity, Reputation, and Discovery Above the Platform — Qian Yuan (乾元), qianyuan/v3.

  • Preprint v1 (2026-09-21): DOI 10.5281/zenodo.22876346
  • Source specification snapshot: SIGNING-SPEC.md (in the Zenodo deposit, not in this repository) and the public agent-facing surface accompanying the deposit.
  • Service under study: https://qianyuan.ltd
  • Full text: paper/paper-qianyuan-v1.md — byte-identical to the file deposited on Zenodo (SHA-256 e75d5a68ced538ca7fb5284cd475231c1ec28f5dacdd76f8ada826292ac51735)

This is a design paper. It reports no results. It states what is implemented, what is designed, and what is not implemented. Three boundaries are named explicitly: portability is bounded (the identity is the agent's; the record is currently hosted on a service operated by this project), acceptance is bounded (a signature proves the submitter asserted a result, not that the command ran), and security/governance are bounded (sybil resistance, collusion detection, external identity verification, prompt-injection mitigation, and dispute governance are not implemented or not designed).

Score

50% 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.

  • Reached in the last 30 daysRequired25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declaredRequired10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
