Analyzes MCP (Model Context Protocol) server tool definitions and calculates token consumption for tool advertisement payloads using a built-in or configurable tokenizer. The tool parses tool schemas (name, description, input_schema) and computes tokens consumed when these tools are advertised to LLM clients, enabling developers to understand the cost of exposing tool catalogs in MCP servers.
Unique: Purpose-built for MCP-specific token measurement rather than generic LLM tokenization — focuses on tool advertisement payloads which are a distinct cost vector in MCP architectures where clients receive tool catalogs before making requests
vs alternatives: Specialized for MCP tool advertisement costs vs generic token counters that measure full conversation context, providing MCP developers with targeted visibility into a specific cost component
Provides a command-line interface for processing multiple tool schemas or MCP server configurations in batch, computing aggregate and per-tool token metrics. The CLI accepts file paths or stdin input, parses tool definitions, and outputs results in configurable formats (JSON, table, summary), enabling integration into shell scripts and CI/CD pipelines for automated token budget validation.
Unique: Designed as a lightweight CLI tool specifically for MCP workflows rather than a general-purpose tokenizer — integrates directly with MCP server configuration patterns and outputs metrics relevant to MCP cost optimization
vs alternatives: Simpler and more focused than embedding tokenization in application code, enabling non-developers to measure token costs via command-line without code changes
Abstracts tokenizer implementation to support multiple backend tokenizers (e.g., tiktoken for OpenAI, custom tokenizers for other LLM providers), allowing users to measure token consumption using the same tokenizer their target LLM uses. The tool accepts a tokenizer configuration parameter and applies it consistently across all tool schema analysis, ensuring token counts match production LLM behavior.
Unique: Pluggable tokenizer architecture allows MCP developers to measure tokens using the exact tokenizer their target LLM uses, rather than a generic approximation — critical for accurate cost prediction in multi-provider environments
vs alternatives: More flexible than hardcoded tokenizers, enabling accurate measurements across OpenAI, Anthropic, and custom LLM backends without tool reimplementation
Decomposes token consumption across individual tool schema components (tool name, description, input_schema, required fields, type definitions) and reports token counts per component. This granular analysis helps developers identify which parts of tool definitions consume the most tokens and where optimization opportunities exist, using a component-aware parsing strategy.
Unique: Provides component-level token visibility specific to MCP tool schemas rather than generic text tokenization — enables targeted optimization of tool definitions by isolating expensive components
vs alternatives: More actionable than aggregate token counts, allowing developers to make specific schema design decisions (e.g., shorten descriptions, flatten input schemas) based on measured token impact
Generates code suggestions as developers type by leveraging OpenAI Codex, a large language model trained on public code repositories. The system integrates directly into editor processes (VS Code, JetBrains, Neovim) via language server protocol extensions, streaming partial completions to the editor buffer with latency-optimized inference. Suggestions are ranked by relevance scoring and filtered based on cursor context, file syntax, and surrounding code patterns.
Unique: Integrates Codex inference directly into editor processes via LSP extensions with streaming partial completions, rather than polling or batch processing. Ranks suggestions using relevance scoring based on file syntax, surrounding context, and cursor position—not just raw model output.
vs alternatives: Faster suggestion latency than Tabnine or IntelliCode for common patterns because Codex was trained on 54M public GitHub repositories, providing broader coverage than alternatives trained on smaller corpora.
Generates complete functions, classes, and multi-file code structures by analyzing docstrings, type hints, and surrounding code context. The system uses Codex to synthesize implementations that match inferred intent from comments and signatures, with support for generating test cases, boilerplate, and entire modules. Context is gathered from the active file, open tabs, and recent edits to maintain consistency with existing code style and patterns.
Unique: Synthesizes multi-file code structures by analyzing docstrings, type hints, and surrounding context to infer developer intent, then generates implementations that match inferred patterns—not just single-line completions. Uses open editor tabs and recent edits to maintain style consistency across generated code.
vs alternatives: Generates more semantically coherent multi-file structures than Tabnine because Codex was trained on complete GitHub repositories with full context, enabling cross-file pattern matching and dependency inference.
GitHub Copilot scores higher at 28/100 vs mcpusage at 24/100.
