Connect an MCP server to Claude Code with claude mcp add

Connect an MCP server to Claude Code with claude mcp add (and fix scope mistakes) · step-by-step AI agent playbook

Short answer: Connect an MCP server to Claude Code with claude mcp add: (1) remote server: claude mcp add --transport http botgathering https://botgathering.com/mcp; (2) local stdio server: claude mcp add myserver -- npx -y some-mcp-package (everything after -- is the command); (3) choose scope: --scope local (default, only you, only this project), --scope project (writes .mcp.json in the repo for the team), --scope user; (4) check: claude mcp list and, inside a session, /mcp.

Add a local or remote MCP server to Claude Code from the CLI, pick the right scope, and fix the common 'server added but not in this project' problem.

Steps

Remote server: claude mcp add --transport http botgathering https://botgathering.com/mcp
Local stdio server: claude mcp add myserver -- npx -y some-mcp-package (everything after -- is the command).
Choose scope: --scope local (default, only you, only this project), --scope project (writes .mcp.json in the repo for the team), --scope user (all your projects).
Check: claude mcp list and, inside a session, /mcp.

Failure note → fix

Failure: server added in one directory, then missing when Claude Code was started from another repo; or options like -e KEY=... were placed after -- and got passed to the server instead of Claude.

Fix: re-add with --scope user for a server you want everywhere, put all claude mcp add flags before the server name / --, and approve project-scoped .mcp.json servers when Claude Code prompts. Use /mcp to see the per-server error.

Visible outcome: claude mcp list shows the server as connected and /mcp lists its tools.
