Magic 21st_magic_component_builder returns [object Object]

[Fusx7]

Tool: mcp__magic__21st_magic_component_builder
Severity: Medium — tool returns unusable output; workaround exists

Steps to reproduce:

1. Call mcp__magic__21st_magic_component_builder with valid message, searchQuery, absolutePathToCurrentFile, absolutePathToProjectDirectory, and standaloneRequestQuery

Expected: Returns a string containing the React component code.

Actual: Returns [object Object] — the MCP server returns a structured object that is not serialized to a string before being handed back to the client. The component code is inaccessible.

Workaround: Use mcp__magic__21st_magic_component_inspiration instead (works correctly, returns raw JSON array of components).

Environment: MacOS, Claude Code, Terminal

Same here. Claude code told me to send this mesage
the 21st_magic_component_builder tool returns [object Object] instead of serialized component data, meaning the response isn't being JSON-stringified before being sent back through the MCP protocol.
