Overview

MCP server enabling Claude to use OpenAI models via API calls, supporting multiple models and basic error handling.

This server is relatively safe for read operations, but the ability to send messages to OpenAI's API introduces moderate risk. The primary risk stems from potential API key exposure and prompt injection vulnerabilities. It's safer when used in controlled environments with trusted users.

Performance depends on the OpenAI API response times. Network latency and API load can impact the overall performance. Consider using smaller models for faster responses.

Using this server incurs costs associated with OpenAI API usage, based on token consumption. Costs vary depending on the model used and the length of the prompts and responses.

Environment Variable

Known Risks

!Exposure of OpenAI API key if environment is compromised.
!Prompt injection attacks leading to unintended model behavior.
!Reliance on OpenAI API availability and security.
!Lack of input validation could lead to unexpected errors or vulnerabilities.
!Potential for excessive API usage leading to unexpected costs.

Safety Score

moderate risk

Positive

+Requires an OpenAI API key, limiting unauthorized access.
+Uses a defined message passing interface.
+No direct filesystem access.
+Limited toolset with specific functions.

Risks

-Relies on external OpenAI API, subject to its vulnerabilities.
-API key is stored in environment variables, posing a risk if exposed.
-Error handling is basic, potentially leading to unhandled exceptions.
-No explicit input sanitization documented, raising injection concerns.
-Potential for prompt injection via user-provided messages to OpenAI.

Who Is This For?

Best For

Users who want to leverage OpenAI models within Claude.
Prototyping and experimenting with different OpenAI models.
Tasks that benefit from the specific capabilities of OpenAI models (e.g., advanced reasoning, code generation).
Scenarios where cost is not a primary constraint.

Not Ideal For

Applications requiring real-time or low-latency responses.
Handling sensitive or confidential data without proper security measures.
High-volume production environments without careful cost management.
Systems requiring strict data residency or compliance.

Autonomy & Execution

Default ModeConfigurable

Autonomy is limited by the capabilities exposed through the OpenAI API and the configuration of the MCP server. User input to Claude directly influences the prompts sent to OpenAI.

StatelessYes

Retry LogicNot documented

ConcurrencySingle-threaded

Production Tip

Monitor OpenAI API usage and costs to prevent unexpected charges. Implement rate limiting if necessary.

FAQ

What OpenAI models are supported?

The server supports gpt-4o, gpt-4o-mini, o1-preview, and o1-mini.

How do I set up the OpenAI API key?

Add the OPENAI_API_KEY environment variable to the mcpServers configuration in claude_desktop_config.json.

How do I specify which model to use?

You can specify the model in the 'model' argument of the openai_chat tool. If not specified, it defaults to gpt-4o.

Where can I find the MCP logs?

The MCP logs are located in ~/Library/Logs/Claude/mcp*.log on macOS.

What are the security risks?

The main risks are API key exposure and prompt injection. Ensure the API key is securely stored and sanitize user inputs.

Can I use this server with other clients besides Claude?

While designed for Claude Desktop, it might be adaptable to other MCP-compatible clients with some modifications.

How do I update the server?

The server is installed via `npx @mzxrai/mcp-openai@latest`, so re-running that command will update it to the latest version.
