Report #60048

[gotcha] MCP servers request broad permissions initially and the user blindly accepts, leading to excessive access

Implement least-privilege by default; require explicit user consent for each new scope or capability; regularly audit connected MCP servers and revoke unused permissions.

Journey Context:
MCP servers often ask for filesystem or network access. Users click 'Allow' to get things working. Over time, the agent accumulates a massive privilege surface area. If any single tool is compromised, the attacker gets the combined privileges of all connected tools.
