# MCP Tool Combinations Explored

Track which combinations of MCP servers have been used in agent designs.

## Combination Matrix

| Primary Tools | Agent Name | Date | Notes |
|--------------|------------|------|-------|
| memory + web + fetch + filesystem | Knowledge Gardener | 2025-11-25 | Async human collaboration via inbox/outbox |
| grep + filesystem + memory + shell | Codebase Archaeologist | 2025-11-25 | Multi-modal: survey, conversational, patrol |

## Tool Affinity Notes

### High-Synergy Combinations
- **memory + web**: Research agents that build persistent knowledge graphs
- **filesystem + grep + shell**: Code analysis and maintenance agents
- **fetch + memory**: Web monitoring and change tracking agents
- **filesystem + text-editor**: Documentation and writing agents

### Underexplored Combinations
- memory + shell: Stateful command orchestration
- grep + web: Cross-referencing local code with online documentation
- fetch + filesystem: Web archiving and local mirroring
