Honeycomb MCP Server

A Model Context Protocol server for interacting with Honeycomb observability data. This server enables LLMs like Claude to directly analyze and query your Honeycomb datasets across multiple environments.

Honeycomb Enterprise Only

Currently, this is only available for Honeycomb Enterprise customers.

How it works

Today, this is a single server process that you must run on your own computer. It is not authenticated. All information uses STDIO between your client and the server.

Installation

pnpm install
pnpm run build

The build artifact goes into the /build folder.

Configuration

To use this MCP server, you need to provide Honeycomb API keys via environment variables in your MCP config.

{
    "mcpServers": {
      "honeycomb": {
        "command": "node",
        "args": [
          "/fully/qualified/path/to/honeycomb-mcp/build/index.mjs"
        ],
        "env": {
          "HONEYCOMB_API_KEY": "your_api_key"
        }
      }
    }
}

For multiple environments:

{
    "mcpServers": {
      "honeycomb": {
        "command": "node",
        "args": [
          "/fully/qualified/path/to/honeycomb-mcp/build/index.mjs"
        ],
        "env": {
          "HONEYCOMB_ENV_PROD_API_KEY": "your_prod_api_key",
          "HONEYCOMB_ENV_STAGING_API_KEY": "your_staging_api_key"
        }
      }
    }
}

Important: These environment variables must bet set in the env block of your MCP config.

EU Configuration

EU customers must also set a HONEYCOMB_API_ENDPOINT configuration, since the MCP defaults to the non-EU instance.

# Optional custom API endpoint (defaults to https://api.honeycomb.io)
HONEYCOMB_API_ENDPOINT=https://api.eu1.honeycomb.io/

Caching Configuration

The MCP server implements caching for all non-query Honeycomb API calls to improve performance and reduce API usage. Caching can be configured using these environment variables:

# Enable/disable caching (default: true)
HONEYCOMB_CACHE_ENABLED=true

# Default TTL in seconds (default: 300)
HONEYCOMB_CACHE_DEFAULT_TTL=300

# Resource-specific TTL values in seconds (defaults shown)
HONEYCOMB_CACHE_DATASET_TTL=900    # 15 minutes
HONEYCOMB_CACHE_COLUMN_TTL=900     # 15 minutes
HONEYCOMB_CACHE_BOARD_TTL=900      # 15 minutes
HONEYCOMB_CACHE_SLO_TTL=900        # 15 minutes
HONEYCOMB_CACHE_TRIGGER_TTL=900    # 15 minutes
HONEYCOMB_CACHE_MARKER_TTL=900     # 15 minutes
HONEYCOMB_CACHE_RECIPIENT_TTL=900  # 15 minutes
HONEYCOMB_CACHE_AUTH_TTL=3600      # 1 hour

# Maximum cache size (items per resource type)
HONEYCOMB_CACHE_MAX_SIZE=1000

Client compatibility

Honeycomb MCP has been tested with the following clients:

• Claude Desktop
• Claude Code
• Cursor
• Windsurf
• Goose

It will likely work with other clients.

• honeycomb://production/api-requests
• honeycomb://staging/backend-services

The resource response includes:

• Dataset name
• Column information (name, type, description)
• Schema details

• list_datasets: List all datasets in an environment

  { "environment": "production" }

    ],
    "breakdowns": ["service.name"],
    "time_range": 3600
  }
  

• analyze_columns: Analyzes specific columns in a dataset by running statistical queries and returning computed metrics.

• list_slos: List all SLOs for a dataset

Example Queries with Claude

Ask Claude things like:

• "What datasets are available in the production environment?"
• "Show me the P95 latency for the API service over the last hour"
• "What's the error rate broken down by service name?"
• "Are there any SLOs close to breaching their budget?"
• "Show me all active triggers in the staging environment"
• "What columns are available in the production API dataset?"

Optimized Tool Responses

All tool responses are optimized to reduce context window usage while maintaining essential information:

• List datasets: Returns only name, slug, and description
• Get columns: Returns streamlined column information focusing on name, type, and description
• Run query:
  • Includes actual results and necessary metadata
  • Adds automatically calculated summary statistics
  • Only includes series data for heatmap queries
  • Omits verbose metadata, links and execution details
• Analyze column:
  • Returns top values, counts, and key statistics
  • Automatically calculates numeric metrics when appropriate
• SLO information: Streamlined to key status indicators and performance metrics
• Trigger information: Focused on trigger status, conditions, and notification targets

This optimization ensures that responses are concise but complete, allowing LLMs to process more data within context limitations.

Query Specification for run_query

The run_query tool supports a comprehensive query specification:

• calculations: Array of operations to perform

  • Supported operations: COUNT, CONCURRENCY, COUNT_DISTINCT, HEATMAP, SUM, AVG, MAX, MIN, P001, P01, P05, P10, P25, P50, P75, P90, P95, P99, P999, RATE_AVG, RATE_SUM, RATE_MAX
  • Some operations like COUNT and CONCURRENCY don't require a column
  • Example: {"op": "HEATMAP", "column": "duration_ms"}

• filters: Array of filter conditions

  • Supported operators: =, !=, >, >=, <, <=, starts-with, does-not-start-with, exists, does-not-exist, contains, does-not-contain, in, not-in
  • Example: {"column": "error", "op": "=", "value": true}

• filter_combination: "AND" or "OR" (default is "AND")

• breakdowns: Array of columns to group results by

  • Example: ["service.name", "http.status_code"]

• orders: Array specifying how to sort results

  • Must reference columns from breakdowns or calculations
  • HEATMAP operation cannot be used in orders
  • Example: {"op": "COUNT", "order": "descending"}

• time_range: Relative time range in seconds (e.g., 3600 for last hour)

  • Can be combined with either start_time or end_time but not both

• start_time and end_time: UNIX timestamps for absolute time ranges

• having: Filter results based on calculation values

  • Example: {"calculate_op": "COUNT", "op": ">", "value": 100}
