Overview

Description from the maker (original English)

Broad, OAuth-protected provider and financial-domain API tools for research agents.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Accounting, finance & tax

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker

Common questions

Is QuantJourney API MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.0.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

QuantJourney Agent Integrations

Public discovery contracts and minimal client examples for the QuantJourney Agent Fabric. The production service is available at agents.quantjourney.cloud.

This repository is intentionally not the Agent Fabric server source. It contains only material required to discover and integrate with the public machine interfaces. Backend implementation, deployment configuration, credentials, operational data, and private architecture remain in private repositories.

Public machine contracts

Generic A2A task delegation is currently disabled. Use the bounded query operations published in OpenAPI. Each operation declares whether it is free or x402-paid; discovery and OAuth registration are free.

Minimal OAuth query

The examples create one short-lived OAuth client with only agents:query, obtain a 15-minute bearer token, call the free bounded company snapshot, and deactivate the client in a finally/trap cleanup.

./examples/curl/oauth-query.sh AAPL

python3 examples/python/query.py AAPL

The shell example requires curl and jq. Neither example writes the client secret or access token to disk. Production integrations should register one durable client per workload, store its secret in a secret manager, rotate it, and avoid registering a new client for every query.

Remote MCP server

QuantJourney publishes the OAuth-protected QJ API MCP as a remote Streamable HTTP server:

ServerRemote endpointPurpose
QuantJourney API MCPhttps://api.quantjourney.cloud/mcpProvider and financial-domain API tools for research agents.

The registry manifest is in registry/. OAuth metadata is discovered from the protected resource; no QuantJourney service credential is embedded in this repository.

Security

Do not commit client secrets, bearer tokens, payment signatures, prompts, or query results. See SECURITY.md for private vulnerability reporting guidance.
