Features

• Semantic Search: AI-powered search across your logs using vector embeddings
• Exact Text Search: Traditional text matching with case-sensitive options
• Documentation Search: AI-powered semantic search across indexed documentation
• Time Filtering: Search logs by time periods (5m, 1h, today, yesterday, 7d, etc.)
• Log Level Filtering: Filter by log levels (info, warn, error, debug)
• Easy Integration: Works with Claude Desktop, Cline, and other MCP clients

3. search_documentation

Semantic (AI-powered) search across indexed documentation.

Parameters:

• query (required): Search query in natural language
• source_id (optional): Specific documentation source ID to search within
• limit (optional): Max results (default 5)
• use_ai (optional): Use AI to structure the answer (default True)

4. list_time_periods

List all supported time period formats.

Time Period Formats

Minutes

• 5m, 5_minutes, 5_mins - Last 5 minutes
• 10m, 15m, 30m - Last 10, 15, 30 minutes

Hours

• 1h, 2h, 6h, 12h - Last 1, 2, 6, 12 hours
• 24h, last_24_hours - Last 24 hours

Days

• today - Today from 00:00 UTC
• yesterday - Full yesterday
• 7d, last_7_days - Last 7 days
• 30d, last_30_days - Last 30 days

Usage Examples

With Claude Desktop

Simply ask Claude:

"Search my logs for authentication errors in the last hour"

"Find all database connection issues from today"

"Show me exact text 'null pointer' in error logs"

"Search documentation for how to implement user authentication"

Development/Testing

Run the server directly:

export STRAYL_API_KEY="your_api_key_here"
strayl-mcp-server

Logging Your Application

To send logs to Strayl, use the Strayl Log API:

import httpx

api_key = "st_your_api_key"
api_url = "https://ougtygyvcgdnytkswier.supabase.co/functions/v1"

async def log_message(message: str, level: str = "info", context: dict = None):
    async with httpx.AsyncClient() as client:
        await client.post(
            f"{api_url}/log",
            json={
                "message": message,
                "level": level,
                "context": context or {}
            },
            headers={"Authorization": f"Bearer {api_key}"}
        )

# Usage
await log_message("User logged in", "info", {"user_id": "123"})
await log_message("Database connection failed", "error", {"db": "postgres"})

Troubleshooting

API Key Issues

If you get authentication errors:

1. Verify your API key starts with st_
2. Check the API key is correctly set in your MCP config
3. Ensure there are no extra spaces or quotes around the key

Connection Issues

If the server fails to connect:

1. Check your internet connection
2. Verify the Strayl API is accessible
3. Check for any firewall or proxy issues

No Results

If searches return no results:

1. Verify you've sent logs to Strayl
2. Check the time period filter isn't too restrictive
3. For semantic search, wait a few seconds for embeddings to generate
