Frequently asked questions

Jacobian is categorized under Data Science Tools and uses a local stdio subprocess. MCP Numpy belongs to Data Science Tools and uses a local stdio subprocess. Pick Jacobian for data science tools work and MCP Numpy for data science tools.

Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.

Jacobian has no declared pricing — check the project's own site. MCP Numpy has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.

Yes. MCP clients support multiple servers: add jacobian and mcp-numpy as separate keys in the same mcpServers object, and your assistant will call tools from either one.
