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 | $0.00835 | $0.00835 |
| Opus 5.5 | $0.00334 | $0.00334 |
| Sonnet 5.5 | $0.00167 | $0.00167 |
| Haiku 4.5 | $0.00084 | $0.00084 |
Grade A, and why
mcp-file-context-server 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 1mo 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.

Development Commands
Build and Run
npm run build- Compile TypeScript to JavaScript in/distnpm run dev- Build and run the server in development modenpm start- Start the compiled server from/distnpm test- Run Jest tests
Environment Configuration
MAX_CACHE_SIZE- Maximum cached entries (default: 1000)CACHE_TTL- Cache time-to-live in milliseconds (default: 1 hour)MAX_FILE_SIZE- Maximum file size in bytes for reading
Architecture Overview
This is a Model Context Protocol (MCP) server that provides file system context and analysis to LLMs. The server is built using the MCP SDK and provides tools for reading, searching, and analyzing code files.
Core Components
Main Server Class (src/index.ts):
FileContextServer- Main server implementation handling MCP protocol- Implements streaming, compression, and chunking for large files
- Provides file watching with automatic cache invalidation
- Handles cross-platform path compatibility (Windows/macOS/Linux)
Services (src/services/):
CodeAnalysisService- Analyzes code complexity, dependencies, and quality metricsFileWatcherService- Real-time file system monitoring with chokidarProfileService- Context generation profiles for different use casesTemplateService- Template rendering for prompts and context
Type Definitions (src/types.ts):
- Complete type definitions for file operations, caching, and analysis
- Error handling with custom
FileOperationErrorclass - Profile and context specification interfaces
Key Features
File Operations:
- Cross-platform path handling using POSIX-style paths for globs
- Streaming support for large files with configurable chunk sizes
- Automatic encoding detection (UTF-8, UTF-16LE with BOM support)
- LRU caching with TTL for performance optimization
Code Analysis:
- Cyclomatic complexity calculation
- Dependency extraction and analysis
- Code quality metrics (duplicate lines, long lines, complex functions)
- Language-specific analysis for TypeScript, JavaScript, Python
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.

mcp-file-context-server CLAUDE.md is an instructions file published in the GitHub repository bsmi021/mcp-file-context-server (39 stars, last pushed 1y ago), licensed MIT. It adds 835 tokens to every session, about $0.0033 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
