Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code.

This is ddoriboo/pension-mcp's own configuration. It tells Claude Code how to work on pension-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything pension-mcp configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

pension-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

This is an MCP (Model Context Protocol) server that integrates with Korea's Financial Supervisory Service (FSS) pension portal APIs. It provides access to 12 different pension-related APIs for collecting and analyzing Korean pension data, including pension savings, retirement pensions, and pension statistics.

Core Commands

Running the Server

python fss_pension_mcp_server/fss_pension_server.py

Installing Dependencies

pip install -r fss_pension_mcp_server/requirements.txt

Testing the Server

python fss_pension_mcp_server/test_server.py

Demo Client

python fss_pension_mcp_server/demo_client.py

Architecture

Main Components

  1. FSSPensionServer Class (fss_pension_server.py:40-231)

    • Core server class that handles all FSS API interactions
    • Manages async HTTP client for API calls
    • Handles XML/JSON response parsing with xmltodict

  2. MCP Server Integration (fss_pension_server.py:230-580)

    • Uses mcp.server framework for protocol compliance
    • Implements 14 tools (12 basic APIs + 2 advanced analysis functions)
    • Handles tool registration and execution

  3. API Endpoints

    • 12 FSS OpenAPI endpoints for different pension data types
    • Base URL: https://apis.data.go.kr/1160100/service
    • Requires service key from Korean government data portal

  4. Advanced Analysis Functions

    • analyze_pension_performance(): Multi-API data analysis
    • generate_pension_recommendation(): Personalized pension advice

Key Dependencies

  • mcp==1.0.0 - Model Context Protocol framework
  • httpx==0.27.0 - Async HTTP client for API calls
  • xmltodict>=0.13.0 - XML to dict conversion for API responses
  • pandas>=2.1.4 - Data manipulation for analysis functions

API Configuration

Service Key Setup

The server requires a valid service key from Korea's public data portal (data.go.kr):

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
