Manual validation: MCP permissions for Loki and Eitri tools

[DylenTurnbull]

Summary

After #403, manually validate MCP permission behavior across the full supported tool set for Loki and Eitri.

Validation scope

For each supported Loki and Eitri MCP tool:

• invoke the tool through a remote Council session;
• confirm the remote approval request is shown and can be answered;
• verify the tool completes after approval;
• verify decline remains declined;
• verify Loki and Eitri Explore remain within Mjolnir’s read-only boundaries.

Expected

Remote MCP approval should work for every supported Loki and Eitri tool without restoring Council-owned permission injection or elevating role access.

Notes

This is a manual testing follow-up for #403, not a feature request or implementation task.
