v1.8.1 — Two-tier MCP tools (53% token reduction)

v1.8.1 — Two-tier MCP tools

Reduces MCP tool definition overhead by 53% while maintaining 100% CLI parity.

Before (v1.8.0): 23 tools, 2487 tokens per API call

Every CLI command was an individual MCP tool. The tool definitions were injected into every LLM call, costing ~2500 tokens.

After (v1.8.1): 9 tools, 1158 tokens per API call

8 core tools (agent uses these mid-task, ~966 tokens):

• memgraph_projects — discover projects
• memgraph_recall — search memories
• memgraph_read — read memory or section
• memgraph_save — store new memory
• memgraph_list — browse memories
• memgraph_edit — update memory
• memgraph_delete — remove memory
• memgraph_recommend — skill recommendations

1 admin meta-tool (~192 tokens):

• memgraph_admin — takes {command, args} and dispatches to 15 rare operations:
  status, config, profile, sessions, init, demo, import, attach, bridge, setup, feedback, query, related, plans, graph_from_dir

Impact

Metric	v1.8.0	v1.8.1	Change
Tools advertised	23	9	-61%
Tokens per API call	2487	1158	-53%
CLI operations covered	23	23	100%

All 23 operations are still accessible — the admin meta-tool just doesn't advertise each one individually in the tool list.
