MCP Phase 3 — Context Enrichment

Richer context for AI agents — project metadata and memory access.

Tools to add:

Tool	Input	Description
cora.get_project_info	—	Repo name, branch, cora version, index status
cora.get_memory	query	Uteke memory recall (if uteke installed)

Design:

• get_project_info is instant (local only)
• get_memory calls uteke subprocess (graceful if not installed)
• JSON output
• Read-only

Depends on:

• feat: MCP Phase 1 — Code Intelligence tools (5 tools) #284 MCP Phase 1
