tg-delete-mcp-tool

Synopsis 

tg-delete-mcp-tool [OPTIONS] --id ID

Description

The tg-delete-mcp-tool command removes MCP (Model Context Protocol) tool configurations from the TrustGraph system. This command deletes MCP tool configurations by ID from the ‘mcp’ configuration group.

Once deleted, the MCP tool will no longer be available for use by agent tools. Any agent tools that reference the deleted MCP tool will need to be updated or removed.

The command includes safety checks to verify the tool exists before attempting deletion and provides clear feedback on the operation status.

Options

  • -u, --api-url URL
    • TrustGraph API URL to connect to
    • Default: http://localhost:8088/ (or TRUSTGRAPH_URL environment variable)
    • Should point to a running TrustGraph API instance
  • --id ID
    • Required: ID of the MCP tool to delete
    • Must match an existing MCP tool identifier
    • Case-sensitive
  • -h, --help
    • Show help message and exit

Examples

Basic MCP Tool Deletion

Remove a weather MCP tool:

tg-delete-mcp-tool --id weather

Custom API URL

Delete MCP tool from a specific TrustGraph instance:

tg-delete-mcp-tool --api-url http://localhost:9000/ --id calculator

Remote Instance

Remove MCP tool from a remote TrustGraph deployment:

tg-delete-mcp-tool -u http://trustgraph.example.com:8088/ --id file-reader

Safety and Verification

The command includes built-in safety features:

Pre-deletion Check

Before deletion, the command verifies the MCP tool exists:

tg-delete-mcp-tool --id nonexistent-tool
# Output: MCP tool 'nonexistent-tool' not found.

Successful Deletion Confirmation

When deletion succeeds:

tg-delete-mcp-tool --id weather
# Output: MCP tool 'weather' deleted successfully.

Verification After Deletion

Confirm the tool was removed:

# List remaining MCP tools
tg-show-mcp-tools

# Verify specific tool is gone
tg-show-mcp-tools | grep "weather" || echo "Tool successfully removed"

Impact on Dependent Agent Tools

Before deleting an MCP tool, consider its usage by agent tools:

Check for Dependencies 

# Show all agent tools and check for MCP tool references
tg-show-tools | grep -A 10 -B 5 "mcp-tool.*weather"

Clean Up Dependent Tools

If agent tools reference the MCP tool being deleted:

# Remove dependent agent tools first
tg-delete-tool --id weather-lookup

# Then remove the MCP tool
tg-delete-mcp-tool --id weather

Batch Operations

Delete Multiple MCP Tools 

#!/bin/bash
MCP_TOOLS=("weather" "calculator" "file-reader")

for tool in "${MCP_TOOLS[@]}"; do
    echo "Deleting MCP tool: $tool"
    tg-delete-mcp-tool --id "$tool"
done

Conditional Deletion 

#!/bin/bash
# Delete MCP tool only if it exists
if tg-show-mcp-tools | grep -q "weather"; then
    tg-delete-mcp-tool --id weather
    echo "Weather MCP tool deleted"
else
    echo "Weather MCP tool not found"
fi

Error Handling

The command handles various error conditions gracefully:

Tool Not Found 

tg-delete-mcp-tool --id nonexistent
# Output: MCP tool 'nonexistent' not found.

API Connection Issues 

tg-delete-mcp-tool --id weather -u http://invalid-host:8088/
# Output: Exception: [Connection error details]

Permission Errors 

# If API access is denied
# Output: Error deleting MCP tool 'weather': [Permission error details]

Network Timeouts 

# If API request times out
# Output: Error deleting MCP tool 'weather': [Timeout error details]

Workflow Integration

Environment Cleanup 

#!/bin/bash
echo "=== Cleaning up test MCP tools ==="

# List all MCP tools starting with 'test-'
test_tools=$(tg-show-mcp-tools | grep -E "^test-" | cut -d: -f1)

for tool in $test_tools; do
    echo "Removing test MCP tool: $tool"
    tg-delete-mcp-tool --id "$tool"
done

echo "Test cleanup complete"

Configuration Migration 

#!/bin/bash
echo "=== Migrating MCP tool configuration ==="

# Export current configuration
tg-show-mcp-tools > old_mcp_config.txt

# Remove old tools
tg-delete-mcp-tool --id old-weather-service

# Add new tools
tg-set-mcp-tool --id weather --tool-url "http://new-weather-api:3000"

echo "Migration complete"

Recovery

If you accidentally delete an MCP tool:

Re-create from Documentation 

# If you have the configuration documented
tg-set-mcp-tool --id weather \
  --tool-url "http://localhost:3000/weather" \
  --remote-name weather-service

Restore from Backup 

# If you have configuration backups
# Parse backup file and recreate tools
source restore_mcp_tools.sh

Best Practices

  1. Verify dependencies: Check for agent tools using the MCP tool before deletion
  2. Backup configurations: Keep records of MCP tool configurations
  3. Clean up dependencies: Remove dependent agent tools first
  4. Test after deletion: Verify system functionality after removing tools
  5. Document changes: Record why MCP tools were removed

Monitoring

Audit Trail 

#!/bin/bash
echo "MCP Tool Deletion Audit - $(date)" >> mcp_audit.log
echo "Deleting MCP tool: $1" >> mcp_audit.log
tg-delete-mcp-tool --id "$1" 2>&1 | tee -a mcp_audit.log

System Health Check 

#!/bin/bash
echo "=== Post-deletion Health Check ==="
echo "Remaining MCP tools:"
tg-show-mcp-tools

echo "Agent tools status:"
tg-show-tools | grep -c "mcp-tool" || echo "No MCP-based agent tools found"
