Frequently asked questions

What LLM providers are supported?

Mcpixir works with any LLM that supports tool calling, including OpenAI, Anthropic, and Groq. You must configure the corresponding API keys.

Can I use multiple MCP servers at the same time?

Yes. Mcpixir supports multi-server configuration. An agent can access tools from all configured servers, and dynamic server selection can be enabled to choose the best server per task.

How do I restrict potentially dangerous tools?

You can provide a list of disallowed tool names when creating the agent (e.g., `disallowed_tools: ["file_system", "network"]`) to control what the agent can use.

Does Mcpixir support HTTP/SSE connections?

Yes. Mcpixir can connect to MCP servers via HTTP using SSE endpoints, configured via the `url` field in the server configuration.

What are the runtime requirements?

Elixir 1.15 or later, and API keys for the chosen LLM provider. The library is available on Hex.pm.
