mcp-predictive-market plugin has unimplemented TODOs

[EricGrill]

Problem

The mcp-predictive-market plugin has 4 unimplemented TODO comments in its memvid client.

Current state:
File: plugins/mcp-predictive-market/src/mcp_predictive_market/state/memvid_client.py

Lines 44, 63, 82, 99 all contain:

# TODO: Implement MCP client call to memvid-state-service

These are core methods for:

• store_state() - Storing market state
• get_state() - Retrieving market state
• get_conversation_history() - Getting conversation context
• search_similar() - Vector search for similar markets

Why it matters:
Publishing a plugin with unimplemented core functionality misleads users and creates a poor experience. The plugin appears to work but critical features are stubs.

Suggested Solution

1. Implement the actual MCP client calls to memvid-state-service
2. Or, document clearly which features are pending
3. Or, remove the plugin from the marketplace until complete
4. Add integration tests for these methods

Acceptance Criteria

• All 4 TODOs resolved with actual implementation
• Integration tests added for memvid client
• Documentation updated to reflect actual capabilities
• Or: Plugin marked as "incomplete" in catalog

Decision: Add to Q2 roadmap.
Milestone: v1.1.0 — Plugin Quality
Priority: P1
Action needed: Implement MCP client calls to memvid-state-service or mark plugin as incomplete in catalog.
