Why do account-level MCP connectors silently eat 100K tokens before you've typed a single word?

Every connector configured at the Claude.ai account level auto-loads into every CLI session with no per-environment opt-out, burning roughly 90K tokens of schema cost across ~240 tools before the user does anything.

What is the “Why do account-level MCP connectors silently eat 100K tokens before you've typed a single word?” problem in 2026?

Every connector configured at the Claude.ai account level auto-loads into every CLI session with no per-environment opt-out, burning roughly 90K tokens of schema cost across ~240 tools before the user does anything.

Who has this problem?

Claude Code CLI users who also have Claude Desktop connectors configured.

Recorded source context

Dataset source note: In a typical setup this silently consumes ~100K tokens of context before the user types anything... ~12 account connectors x avg 20 tools each ~= ~240 tools with combined schema cost of ~90K tokens.

Existing players in this space

  • Revoke OAuth entirely: Only full-scope workaround, kills Desktop integrations too.
  • Disable each connector by hand: Tedious, must be redone if connectors change.

What existing players are missing

A per-environment opt-out (env var, allowlist, or scope-aware login) that keeps account connectors available in Claude Desktop while excluding them from CLI sessions by default.
