What is bitso-mcp CLAUDE.md?

Project instructions for a TypeScript MCP server template. TypeScript is a programming language that adds type checking to JavaScript, while MCP connects assistants to tools.

Use them when building, testing, debugging, or extending a TypeScript MCP server.

They explain the project’s architecture, testing approach, configuration, logging, and supported connection methods before development begins.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01371	$0.01371
Opus 5	$0.00685	$0.00685
Sonnet 5	$0.00274	$0.00274
Haiku 4.5	$0.00137	$0.00137

Security

Grade A, and why

bitso-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 5d 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.

Claude Context - TypeScript MCP Template

Expertise Areas

I am an expert TypeScript MCP (Model Context Protocol) developer with deep knowledge of:

MCP server architecture and tool registration patterns
TypeScript/ESM module systems and build tooling
Two-tier testing strategies (unit + integration)
Production logging and debugging systems
API client design with caching and error handling

Project Context

This is a production-ready TypeScript MCP template that demonstrates best practices for building MCP servers. It serves as a foundation for developers to create their own MCP servers with:

Dual transport support (stdio for Claude, HTTP for development)
Comprehensive testing infrastructure
Type-safe configuration management
Robust error handling and logging
Tool generation utilities

Key Architecture Decisions

Dual Transport Support

stdio: Production mode for Claude Desktop integration
HTTP: Development mode for debugging and testing
Seamless switching via command-line arguments

Two-Tier Testing Strategy

Unit tests (tests/unit/): Fast, MSW-mocked, business logic focused
Integration tests (tests/integration/): Real MCP protocol testing
No inline function duplications - tests use actual server instances

Project-Root-Aware Logging

Logs written to mcp-debug.log in project root
Works correctly from both src/ and dist/ locations
Structured logging with timestamp and component prefixes

Type-Safe Configuration

Zod schemas for environment variable validation
Clear error messages for missing/invalid configuration
Default values and optional parameters

Development Workflow

Building and Testing Changes

IMPORTANT: After making changes to TypeScript files, always rebuild:

npm run build

Development cycle:

Make changes to TypeScript files in src/
Run npm run build to compile changes
IMPORTANT: Restart Claude Desktop to get latest MCP server build
Test changes in Claude Desktop or via HTTP mode
Debug using logs in mcp-debug.log
Run tests: npm test

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.
