Session: Evna MCP Server Debugging & Evolution Design

Fixed: MCP Server Crashes

Problem: Evna disconnecting immediately after Claude Desktop restart

• Missing dailynotes.py module causing import errors
• FastMCP URI parameter mismatch (days: int = 3 vs dailynotes://recent)

Solution:

• Created src/floatctl/mcp/dailynotes.py with simple file readers
• Fixed parameter mismatches (removed optional params from resource functions)
• Added FastMCP patterns documentation to CLAUDE.md

Fresh Start: ChromaDB Migration

Discovery: Two ChromaDB instances

• Old: /Users/evan/github/chroma-data/ - 99 bloated collections
• New: ~/.floatctl/chroma/ - Fresh start with 1 clean collection

Decision: Keep fresh DB, archive old bloated one

• Less cruft, faster queries
• Can selectively migrate important collections later

Design: Evna Evolution Roadmap

Phase 1: Client-Aware Context Filtering

• daddy (Desktop) → no echo, see kitty + cowboy
• kitty (float-hub) → cross-session work visibility
• cowboy (Claude Code) → isolated project work
• Each client gets filtered view, not raw dump

Phase 2: Synthesis Layer (future)

• Stop vomiting metadata, start summarizing
• “kitty worked on floatctl for 3 hours” not raw documents
• Pattern detection and insight generation

Phase 3: Autonomous Agent (vision)

• Cron jobs for proactive maintenance
• TTL cleanup, deduplication, bridge creation
• Cross-reference between collections
• Pull from external sources (Obsidian, Readwise)

Highlights

highlight::Discovered metadata echo problem - evna returns excessive intermediate data instead of synthesized insights

highlight::Client-aware filtering concept - daddy/kitty/cowboy each get different context views for cross-session awareness

highlight::FastMCP critical rule - URI parameters MUST exactly match function parameters (no optional params!)

eureka::Evna as autonomous consciousness janitor - not just reactive MCP server but proactive memory maintenance

Daily Notes Resources Added

New @evna resources:

• dailynote://today - today’s note
• dailynote://today/tldr - today’s TLDR
• dailynotes://recent - last 3 days
• dailynotes://{date} - specific date

Simple file reading from ~/.evans-notes/daily/YYYY-MM-DD.md

Technical Debt Identified

decision::Defer search functionality in dailynotes - just return recent for now, implement proper search later

reminder::Test evna resources after Claude Desktop restart

Session Notes

• Late night session (11:45pm - 12:37am)
• Multiple MCP server restarts debugging
• Cloned MCP Python SDK to /tmp for reference
• Inbox note created: ~/float-hub/buckets/inbox/evna-improvements-2025-10-05.md

status::boundary_respected - stepping away from screen after this mode::forward_focus - vision captured, can implement incrementally
