Run this in a terminal to add the server to Claude Code.
What this does
fiber exposes a set of tools to Claude over the Model Context Protocol. After you add it to claude_desktop_config.json (snippet above) and restart Claude Desktop, those tools become callable inside any conversation.
Requirements
This server needs the following environment variables to be set before it can run:
FIBER_API_URL FIBER_API_KEY FIBER_ENABLE_WRITE FIBER_MCP_TOOLS_ALLOWLIST FIBER_HTTP_TIMEOUT
Set these via the env object in your MCP config (see claude_desktop_config.json snippet above).
