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 | $0.00948 | $0.00948 |
| Opus 5 | $0.00474 | $0.00474 |
| Sonnet 5 | $0.00190 | $0.00190 |
| Haiku 4.5 | $0.00095 | $0.00095 |
Grade A, and why
mcp-ts-toolskit 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 @thomas92fr/mcp-ts-toolskit - a comprehensive Model Context Protocol (MCP) server providing secure, configurable tools for file system operations, web searches, document conversion, project management, and generative AI capabilities via PiAPI.ai integration.
Common Commands
Building and Development
npm run compile- Compile TypeScript source code and make scripts executablenpm run build- Full build process (compile + webpack bundle)npm run watch- Watch mode for development with automatic recompilationnpm run inspector- Build and run with MCP inspector for debugging
Key Build Files
- Main entry point:
src/index.ts - Compiled output:
build/ - Bundled distribution:
dist/bundle.cjs
Architecture Overview
Core Structure
The project follows a modular architecture with tools organized by category:
- FastMCP Framework: Uses
fastmcpas the MCP server foundation - Configuration System: JSON-based config with path validation and security
- Logging: Winston-based logging with daily rotation
- Tool Categories: FileSystem, Web, Git, Pandoc, NPM, .NET, System, PiAPI
Main Application Flow (src/index.ts)
- Loads configuration from
MCP_TOOLSKIT_CONFIG_PATHenvironment variable - Initializes Winston logger with file rotation
- Creates FastMCP server instance
- Registers all tool categories and their individual tools
- Adds resource endpoints for logs and prompts
- Starts server on stdio transport
Tool Architecture Pattern
Each tool follows a consistent pattern:
- Located in
src/tools/{category}/{tool_name}.ts - Exports an object with
Add_Tool(server, config, logger)method - Uses Zod schemas for parameter validation
- Implements security through config.validatePath() and config.validateTool()
Configuration System (src/models/appConfig.ts)
- IAppConfig Interface: Defines configuration structure
- Security: Path validation ensures operations stay within
AllowedDirectories - Tool Control:
ForbiddenToolsarray can disable specific tools - API Integration: Separate config sections for BraveSearch and PiAPI
- Environment Support: Configuration loaded via JSON file path from env var
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.
