claude mcp add codebase-memory-mcp -- npx -y codebase-memory-mcpScopes and team sharing
- Every server has a scope. Local, the default, is only for you in the current project;
--scope usermakes it available in every project;--scope projectwrites it to.mcp.jsonso the whole team gets it. claude mcp add-json <name> '<json>'takes a full server entry when the plainaddflags are not enough.- Project servers from
.mcp.jsonask for approval the first time;claude mcp reset-project-choicesasks again. - Servers already set up in Claude Desktop can be imported on macOS and WSL.

MCP_TIMEOUTenvironment variable. - Large tool output is capped;
MAX_MCP_OUTPUT_TOKENSraises the cap. ${VAR}and${VAR:-default}are expanded in command, args, env, url and headers.

Claude CodeのMCPに関する質問
How do I add an MCP server to Claude Code?
Run claude mcp add <name> -- <command> for a local server, or claude mcp add --transport http <name> <url> for a remote one. Every server page on HostedMCP has the exact command.
Where does Claude Code store MCP servers?
Local and user scope servers go in ~/.claude.json. Project scope servers go in .mcp.json at the project root, which you can commit for your team.
Does Claude Code support remote MCP servers with OAuth?
Yes. Add the server with --transport http and sign in from /mcp when Claude Code asks.
How do I check that a server loaded?
Run claude mcp list, or open /mcp in a session; a connected server shows a check mark.
