Claude Code cannot see a newly enabled MCP - cc-switch

Quick fix

Upgrade cc-switch to the latest version, or copy the contents of the sibling .claude.json into the one inside CLAUDE_CONFIG_DIR by hand.

Error output
Claude Code 看不到新启用的 MCP。cc-switch DB 里 enabled_claude=1，UI 显示已启用，但 Claude Code 完全没反应。
English translation

Claude Code cannot see a newly enabled MCP. The cc-switch DB has enabled_claude=1 and the UI shows it enabled, but Claude Code does not react at all.

Cause

Section titled “Cause”

Reading the source shows that with CLAUDE_CONFIG_DIR set explicitly, Claude Code reads .claude.json and other config from inside that directory. But older cc-switch versions derived the MCP config path wrongly and wrote it as a sibling of the custom config directory, so the file cc-switch writes and the path Claude Code reads do not match. Early versions also failed to detect the CLAUDE_CONFIG_DIR environment variable automatically.

Fix

Section titled “Fix”

  1. Upgrade cc-switch to the latest version for the .claude.json path derivation fix under a custom config directory and the environment variable detection fix.

  2. If you are not upgrading yet, copy the fields from the sibling .claude.json cc-switch generated into the .claude.json under the CLAUDE_CONFIG_DIR path by hand.

  3. To migrate session history off the C drive, set the CLAUDE_CONFIG_DIR environment variable and change the CLI tool directory in CC Switch settings to the same path, or create a directory link with mklink /J.

FAQ

Section titled “FAQ”
Why are there two .claude.json files on disk?
Because cc-switch wrote the MCP as a sibling of the override directory while Claude Code, in CLAUDE_CONFIG_DIR mode, reads the .claude.json inside the directory.
What are the default Claude Code config paths?
By default settings.json lives in ~/.claude/ while the global state and MCP config .claude.json lives at ~/.claude.json — the two are split by design.
