MCP Setup
Configure required MCP servers for agent-harness token efficiency and learning loops.
Required MCP Servers
| Server | Purpose | API Key |
|--------|---------|---------|
| token-efficient | CSV/log processing, sandbox execution (98% token savings) | None |
| context-graph | Semantic decision trace search | Voyage AI |
Setup Instructions
Quick setup - Run scripts/setup-all.sh in your project directory:
cd /path/to/your/project
bash ~/.claude/skills/mcp-setup/scripts/setup-all.sh
This will:
- Create
mcp/folder in your project - Clone and build token-efficient MCP
- Clone and install context-graph MCP
- Prompt for Voyage AI API key
- Generate
.mcp.jsonin project root
Manual setup (if needed):
1. Install token-efficient MCP in mcp/
mkdir -p mcp
git clone https://github.com/gurusharan/token-efficient-mcp.git mcp/token-efficient-mcp
cd mcp/token-efficient-mcp
npm install
npm run build
2. Install context-graph MCP in mcp/
git clone https://github.com/gurusharan/agent-harness.git mcp/context-graph-mcp
cd mcp/context-graph-mcp/context-graph-mcp # or just mcp/context-graph-mcp
pip install -r requirements.txt
3. Create .mcp.json in project root
{
"mcpServers": {
"token-efficient": {
"command": "node",
"args": ["mcp/token-efficient-mcp/dist/index.js"]
},
"context-graph": {
"command": "uv",
"args": ["--directory", "mcp/context-graph-mcp", "run", "python", "server.py"],
"env": {
"VOYAGE_API_KEY": "your_key_here"
}
}
}
}
4. Restart Claude Code
After setup, restart Claude Code to load MCP servers.
Verification
After setup, test:
# Via context-graph MCP
context_store_trace(decision="Test setup", category="general")
context_list_categories()
Troubleshooting
| Issue | Solution |
|-------|----------|
| module 'chromadb' not found | pip install chromadb |
| VOYAGE_API_KEY not found | Set env var or add to mcp.json env |
| Tools not available | Restart Claude Code |
| srt: command not found | Install token-efficient MCP |
Scripts
| Script | Purpose |
|--------|---------|
| scripts/setup-all.sh | Use this - Auto-detects paths, sets up both MCP servers |
| scripts/verify-setup.sh | Check if MCP servers are working |
| scripts/install-token-efficient.sh | Standalone token-efficient MCP installer |
