MCP server for the BLS Occupational Employment and Wage Statistics (OEWS) API. Market wage data for IGCEs and price analysis.

bls-oews-mcp

MCP server for the BLS Occupational Employment and Wage Statistics (OEWS) API. Market wage data for IGCE development, price analysis, and labor market research.

Optional free API key for higher rate limits. Works without a key at reduced limits.

What it does

Exposes the BLS OEWS API as 7 MCP tools:

Core

• get_wage_data - Wage statistics for an occupation by SOC code (national, state, or metro)
• compare_metros - Compare wages for one occupation across multiple metro areas
• compare_occupations - Compare wages across multiple occupations in one location

Workflow

• igce_wage_benchmark - Wage benchmarks with burdened rate estimates for IGCE development
• detect_latest_year - Check if newer OEWS data has been released

Reference

• list_common_soc_codes - SOC code mappings for federal IT/professional services
• list_common_metros - Metro area MSA codes

Authentication (optional)

Without a key, the server uses BLS v1 API (25 queries/day). With a key, it uses v2 (500 queries/day). Register free at data.bls.gov/registrationEngine.

Installation

uvx bls-oews-mcp

Claude Desktop configuration

Without key:

{
  "mcpServers": {
    "bls-oews": {
      "command": "uvx",
      "args": ["bls-oews-mcp"]
    }
  }
}

With key (recommended):

{
  "mcpServers": {
    "bls-oews": {
      "command": "uvx",
      "args": ["bls-oews-mcp"],
      "env": {
        "BLS_API_KEY": "your-api-key-here"
      }
    }
  }
}

Example prompts

• "What's the national median salary for Software Developers (SOC 151252)?"
• "Compare Systems Analyst wages in DC, Seattle, and Baltimore."
• "Build IGCE wage benchmarks for Program Manager, Software Developer, and Help Desk at the DC metro area with a 2.0x burden factor."
• "Is $195/hr reasonable for a Senior Software Developer? Show me the BLS market data."
• "What do Information Security Analysts earn in Virginia vs nationally?"

Important: base wages, not burdened rates

BLS OEWS data represents employer-reported base wages (no fringe, overhead, G&A, or profit). To estimate fully burdened hourly rates for an IGCE, apply a burden multiplier:

• 1.5x-1.7x: lean contractor
• 1.8x-2.2x: mid-range professional services
• 2.0x-2.5x: large contractor with clearance overhead
• 2.5x-3.0x: high-overhead (SCIF, deployed)

The igce_wage_benchmark tool applies the multiplier automatically.

Data year

OEWS data lags ~2 years. The server defaults to 2024 (May 2024 estimates, released April 2025). Do NOT query 2025 or 2026. Use detect_latest_year to check for newer releases.

Companion tools

Use alongside gsa-calc-mcp (GSA CALC+ ceiling rates) for complete pricing analysis. BLS provides what the market pays; CALC+ provides what GSA contractors charge. Together they form the IGCE pricing toolkit.
