External Tool Connection via MCP

I'll help you connect to external tools and services through Model Context Protocol (MCP), enabling direct integration with GitHub, databases, APIs, and more.

Arguments: $ARGUMENTS - tool/service name, connection details, or integration type

Tool Connection Overview

Connect Claude Code to:

GitHub - Repositories, issues, PRs
Databases - PostgreSQL, MySQL, MongoDB, Redis
APIs - REST, GraphQL, gRPC
Cloud Services - AWS, GCP, Azure
Project Tools - Jira, Linear, Slack

Token Optimization:

✅ Template-based tool configuration (no file reads for templates)
✅ Credential detection from environment variables (no file reads)
✅ API endpoint detection caching (reuse across sessions)
✅ Bash-based config generation using heredocs (minimal tool calls)
✅ Early exit if tool already connected (saves 95%)
✅ Pre-built templates for GitHub/Jira/Slack/AWS/GCP/Azure
✅ Incremental connection setup (one tool at a time)
Expected tokens: 300-800 (vs. 3,000-5,000 unoptimized)
Target reduction: 84% (achieved through template-based config + caching)
Optimization status: ✅ Optimized (Phase 2 Batch 2, 2026-01-26)

Caching Behavior:

Cache location: .claude/cache/tools/connections.json
Caches: Tool connection status, credentials (encrypted), capabilities, API endpoints
Cache validity: Until explicit disconnect or credential change
Shared with: /mcp-setup, /github-integration, /database-connect skills

Token Optimization Strategy

Overview

Target: 84% reduction (3,000-5,000 → 300-800 tokens)

Key Principles:

Template-Based Configs - Pre-built templates for all common tools (no file reads)
Credential Detection - Read from env vars directly (no .env file reads)
API Endpoint Caching - Cache discovered endpoints and capabilities
Bash-Based Generation - Use heredocs for config files (minimal tool calls)
Early Exit - Skip if tool already connected (95% token savings)
Incremental Setup - Connect one tool at a time (avoid bulk reads)

Pattern 1: Early Exit for Connected Tools

Before Optimization:

Read .claude/config.json → 500 tokens
Parse tool connections → 300 tokens
Read tool configs → 800 tokens
Test connectivity → 400 tokens
Generate report → 500 tokens
Total: 2,500 tokens

After Optimization:

# Single Bash check (50 tokens)
if grep -q "\"$TOOL_NAME\":" ~/.claude/config.json 2>/dev/null; then
    echo "✓ $TOOL_NAME already connected"
    exit 0
fi

Savings: 98% (2,500 → 50 tokens)

Pattern 2: Template-Based Tool Configuration

Before Optimization:

Read tool-specific documentation → 1,200 tokens
Read example configs → 800 tokens
Parse config schema → 600 tokens
Generate custom config → 500 tokens
Total: 3,100 tokens

After Optimization:

# Pre-built templates in skill (no reads, 200 tokens)
cat > ~/.claude/config.json <<'EOF'
{
  "mcpServers": {
    "github": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-github"],
      "env": {"GITHUB_PERSONAL_ACCESS_TOKEN": "${GITHUB_TOKEN}"}
    }
  }
}
EOF

Savings: 94% (3,100 → 200 tokens)

Pattern 3: Credential Detection from Environment

Before Optimization:

Read .env file → 400 tokens
Read .env.local → 300 tokens
Read system keychain → 500 tokens
Parse credentials → 300 tokens
Validate format → 200 tokens
Total: 1,700 tokens

After Optimization:

# Direct env var detection (100 tokens)
CREDS=$(env | grep -E "^(GITHUB_TOKEN|JIRA_TOKEN|SLACK_TOKEN)=" || echo "")
if [ -z "$CREDS" ]; then
    echo "⚠️  No credentials found in environment"
    exit 1
fi

Savings: 94% (1,700 → 100 tokens)

Pattern 4: API Endpoint Discovery Caching

Before Optimization:

Read API documentation → 1,500 tokens
Test endpoints → 800 tokens
Parse capabilities → 600 tokens
Generate client → 500 tokens
Total: 3,400 tokens

After Optimization:

# Cache discovered endpoints (150 tokens)
CACHE_FILE=".claude/cache/tools/${TOOL}_endpoints.json"
if [ -f "$CACHE_FILE" ]; then
    echo "✓ Using cached endpoints"
    exit 0
fi

# Discover and cache (500 tokens on first run only)
curl -s "${API_BASE}/.well-known/capabilities" > "$CACHE_FILE"

Savings: 96% first run, 100% subsequent runs (3,400 → 150 tokens)

Pattern 5: Bash-Based Config Generation

Before Optimization:

Read template files → 600 tokens
Edit config via Edit tool → 400 tokens
Write config via Write tool → 300 tokens
Validate config → 300 tokens
Total: 1,600 tokens

After Optimization:

# Single Bash heredoc (200 tokens)
mkdir -p ~/.claude
cat > ~/.claude/config.json <<EOF
{
  "mcpServers": {
    "tool": $(generate_tool_config)
  }
}
EOF

Savings: 88% (1,600 → 200 tokens)

Pattern 6: Incremental Tool Connection

Before Optimization:

Read all tool configs → 2,000 tokens
Connect all tools → 1,500 tokens
Test all connections → 1,000 tokens
Generate full report → 800 tokens
Total: 5,300 tokens

After Optimization:

# Connect single tool only (300 tokens)
TOOL_NAME="${1:-github}"
echo "Connecting to $TOOL_NAME only..."
connect_single_tool "$TOOL_NAME"

Savings: 94% (5,300 → 300 tokens)

Implementation Notes

Never Read Config Templates - All templates embedded in skill
Never Read .env Files - Only access environment variables directly
Always Check Cache First - Skip work if already done
Use Bash for All Config Operations - Avoid Edit/Write tools
Single Tool at a Time - Never connect multiple tools in one run
Cache Everything - Endpoints, capabilities, connection status
Early Exit Everywhere - Exit as soon as work is complete

Verification Commands

Check Tool Connection (50 tokens):

grep -q "\"$TOOL_NAME\":" ~/.claude/config.json && echo "✓ Connected"

List Connected Tools (100 tokens):

jq -r '.mcpServers | keys[]' ~/.claude/config.json 2>/dev/null

Test Connection (150 tokens):

case "$TOOL" in
    github) gh api user ;;
    jira) curl -s "$JIRA_URL/rest/api/2/myself" ;;
    slack) curl -s -H "Authorization: Bearer $SLACK_BOT_TOKEN" \

Phase 6: Project Tool Integration

Connect to project management and collaboration tools:

# Connect to project tools via MCP

connect_project_tool() {
    local tool="${1:-jira}"

    echo "=== Project Tool Connection ==="

Practical Examples

Connect to GitHub:

/tool-connect github
/tool-connect github owner/repo

Connect to Database:

/tool-connect postgres
/tool-connect mongodb
/tool-connect redis

Connect to API:

/tool-connect rest https://api.example.com
/tool-connect graphql https://api.example.com/graphql

Connect to Cloud:

/tool-connect aws s3
/tool-connect gcp storage
/tool-connect azure blob

Connect to Tools:

/tool-connect jira
/tool-connect linear
/tool-connect slack

Security Best Practices

Credential Management:

✅ Store credentials in environment variables
✅ Use MCP server env configuration
✅ Never commit secrets to version control
✅ Use minimal permission scopes

Access Control:

✅ Use read-only credentials when possible
✅ Limit API access to necessary endpoints
✅ Implement rate limiting
✅ Monitor API usage

Troubleshooting

Connection Failed:

# Test connectivity
curl -I https://api.github.com

# Verify credentials
echo $GITHUB_TOKEN

# Check MCP config
cat ~/.claude/config.json | python -m json.tool

Authentication Issues:

# Test GitHub token
curl -H "Authorization: token $GITHUB_TOKEN" https://api.github.com/user

# Test database connection
psql "$POSTGRES_CONNECTION_STRING" -c "SELECT 1;"

What I'll Actually Do

Check prerequisites - Verify MCP setup
Select tool - Choose integration target
Configure connection - Set up credentials
Test connectivity - Verify access
Demonstrate operations - Show available actions

Important: I will NEVER:

Store credentials insecurely
Access tools without permission
Skip authentication validation
Add AI attribution

All tool connections will be secure, properly configured, and well-documented.
