Overview

AI-generated overview

A remote, OAuth-protected MCP server exposing QuantJourney provider and financial-domain API tools for research agents.

What you can do
Gives research agents access to QuantJourney's provider and financial-domain API tools through a remote Streamable HTTP endpoint, aimed at bounded query operations rather than generic task delegation. The published contracts include an Agent Card, a bounded-query OpenAPI specification, agent instructions and a query catalogue. Each operation declares whether it is free or x402-paid; discovery and OAuth registration are free. A free bounded company snapshot is the documented example query.
When to use it
Worth adding when an assistant needs financial-domain data and provider API queries from QuantJourney for research work, and you are prepared to authenticate through OAuth. Not suitable if you need generic A2A task delegation, which the README says is currently disabled.
Requirements
A remote endpoint at api.quantjourney.cloud over Streamable HTTP; no local package or runtime. OAuth is required: register a client with the agents:query scope and obtain a short-lived bearer token. The shell example needs curl and jq. Network access to the service is required.
Before you install
Some query operations are x402-paid, so calls can incur charges; check each operation's declared pricing before use. OAuth client secrets and bearer tokens are credentials: the README advises storing secrets in a secret manager, rotating them, and not committing secrets, tokens, payment signatures, prompts or query results. Generic A2A task delegation is disabled.

Installation

In SourceWeft

  1. Open QuantJourney API MCP in the dashboard and add it to a workspace.
  2. Connect the required 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.QuantJourneyOrg%2Fqj-api-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. The client completes OAuth sign-in on first connect.

README

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.

bash
./examples/curl/oauth-query.sh AAPLpython3 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
