# MCP Tool Execution
Execute MCP operations via **Gemini CLI** to preserve context budget.
## Execution Steps
1. **Execute task via Gemini CLI** (using stdin pipe for MCP support):
```bash
# IMPORTANT: Use stdin piping for MCP tasks (historically more reliable for MCP server init)
# Read model from .claude/.ck.json: gemini.model (default: gemini-3-flash-preview)
echo "$ARGUMENTS. Return JSON only per GEMINI.md instructions." | gemini -y -m <gemini.model>
```
2. **Fallback to mcp-manager subagent** (if Gemini CLI unavailable):
- Use `mcp-manager` subagent to discover and execute tools
- If the subagent got issues with the scripts of `ak:mcp-management` skill, use `ak:mcp-builder` skill to fix them
- **DO NOT** create ANY new scripts
- The subagent can only use MCP tools if any to achieve this task
- If the subagent can't find any suitable tools, just report it back to the main agent to move on to the next step
## Important Notes
- **MUST use stdin piping for MCP tasks** — historically more reliable for MCP server initialization
- Use `-y` flag to auto-approve tool execution
- **GEMINI.md auto-loaded**: Gemini CLI automatically loads `GEMINI.md` from project root, enforcing JSON-only response format
- **Parseable output**: Responses are structured JSON: `{"server":"name","tool":"name","success":true,"result":<data>,"error":null}`
- **Error handling**: Check gemini exit code — if non-zero or output contains `GaxiosError`/`RESOURCE_EXHAUSTED`/`MODEL_CAPACITY_EXHAUSTED`/`PERMISSION_DENIED`/`UNAUTHENTICATED`, fall back to mcp-manager subagent
## Anti-Pattern for MCP Tasks
```bash
# AVOID for MCP tasks - historically reported MCP init issues in headless mode
gemini -y -m <gemini.model> --prompt "..."
# Use stdin piping instead for MCP tool execution
echo "..." | gemini -y -m <gemini.model>
```
**Note**: `--prompt` is fine for non-MCP tasks (research, analysis). Only MCP tool execution requires stdin piping.
