The OpenNews MCP server is a community-maintained MCP server that provides comprehensive financial and cryptocurrency news aggregation with AI analysis. It requires an API token for authentication and communicates with external services via HTTP and WebSocket. Installation involves setting environment variables and configuring the client JSON. Since the server has network permissions and reads local configuration, there is a risk of API key leakage, but a source code review can help verify that the server only connects to expected endpoints. It is suitable for traders, researchers, and AI assistant users interested in real-time market information.

Why each score

Reliability 7/20: Only the README and repository metadata were available; no actual source under src/opennews_mcp, no CI configuration, and no tests were supplied. The README claims 15+ tools and WebSocket push, but tool behavior, error handling, and dependency control cannot be verified from source. The static rule forbids awarding above 12 without execution evidence, and missing evidence must be a deduction, so 7 is given.
Security and permissions 8/20: The README shows that tokens are read from environment variables or config.json, claims connections only to ai.6551.io, and includes a prompt for AI-assisted source review. No red-line issue is visible. However, without the source code it is impossible to verify data-flow boundaries, exfiltration resistance, least-privilege behavior, or safety of the OPENNEWS_API_BASE/OPENNEWS_WSS_URL overrides; these unknowns justify a deduction.
Maintenance 10/20: The repository is not archived, has an MIT license, shows only 1 open issue, and the README appears actively maintained with multi-language and multi-client documentation. Still, commit frequency, release cadence, dependency updates, and security-response channels were not evidenced, so full marks cannot be given.
Documentation 16/20: The README is comprehensive: quick install, configuration for many clients, a full tool list, tables of 85+ sources, WebSocket subscription protocol, data structures, and config examples. It lacks explicit cost/limits, rate-limit guidance, troubleshooting, and error-code documentation, so the score is capped at 16.
Setup experience 14/20: The setup path is clear: obtain a token, then run via uv with ready-made JSON/YAML examples for Claude Code, Claude Desktop, Cursor, Windsurf, Cline, Continue.dev, Zed, and other clients. However, no CI workflow or committed tests verify those steps, so under the static calibration rule the score cannot exceed 15; given the clarity and multi-platform coverage, 14 is assigned.

Fit and risk

What it can accessUses the network

Best for

Traders and investors who want real-time financial and crypto news at their fingertips.
Developers seeking AI-powered market insights with scores and signals.
Researchers aggregating news within AI assistant environments like Claude.

Not for

Users who require fully local data processing or no API key.
Users needing historical data or deep archive access.
Users who need purely offline news aggregation without external dependencies.

Required permissions

Requires network access to connect to the 6551 API (ai.6551.io) and WebSocket server.
Requires an API token (OPENNEWS_TOKEN) for authentication.
Requires filesystem permissions to read the config file (config.json) and run commands in the local project directory.

Risks and side effects

This server is not an official product; it is third-party (6551Team) and relies on an external API.
API key could be exposed if misconfigured or leaked in logs.
News content may be subject to copyright or usage terms; users should ensure compliance.
External API could be down or change, affecting functionality.
Server may send push notifications or inaccurate data due to third-party sources.

Setup

Before you start

Runtime：Python

OPENNEWS_TOKEN requiredsecret 6551 API Bearer Token, obtained at https://6551.io/mcp; required.

Other optional settings (3)

OPENNEWS_API_BASE optional Optional override for the REST API base URL (default https://ai.6551.io).

OPENNEWS_WSS_URL optional Optional override for the WebSocket URL (default wss://ai.6551.io/open/news_wss).

OPENNEWS_MAX_ROWS optional Optional max results per request, default 100.

Get an API token at https://6551.io/mcp.
Clone the repository: git clone https://github.com/6551Team/opennews-mcp.git.
Set the environment variable: export OPENNEWS_TOKEN="<your-token>".
Add the JSON configuration to your MCP client (e.g., Claude Desktop) as per the README, replacing /path/to/opennews-mcp with your actual path.
Restart your client.

claude_desktop_config.json

{
  "mcpServers": {
    "opennews": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/opennews-mcp",
        "run",
        "opennews-mcp"
      ],
      "env": {
        "OPENNEWS_TOKEN": "<your-token>"
      }
    }
  }
}

Shown for Claude Desktop. Other clients may use a different file or key (VS Code uses "servers") — the configurator below converts it.

.vscode/mcp.json

{
  "servers": {
    "opennews": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/opennews-mcp",
        "run",
        "opennews-mcp"
      ],
      "env": {
        "OPENNEWS_TOKEN": "<your-token>"
      }
    }
  }
}

Goes in your project's .vscode/mcp.json (VS Code uses a "servers" key).

Terminal

claude mcp add opennews -e 'OPENNEWS_TOKEN=<your-token>' -- uv --directory /path/to/opennews-mcp run opennews-mcp

Run it in a terminal; replace any <…> placeholders with your own values first.

Generate and validate client config

Check that it works

After install, ask "Get the latest crypto news"; if the client calls get_latest_news and returns articles with aiRating fields, the connection works.

Troubleshooting

Ensure OPENNEWS_TOKEN environment variable is correctly set and the token is valid.
Check network connectivity and firewall blocking ai.6551.io.
Verify the `/path/to/opennews-mcp` path is correct and the project is properly synced.
If connection fails, check the API base URL and WebSocket URL configurations.
Ensure that the MCP client supports stdio transport and the uv command is correctly configured.
Check server logs for detailed errors.
