What it can do
| Tool | What it says it does |
|---|---|
convert_schema | Turn one JSON Schema into OpenAI, Anthropic, and MCP tool definitions with the same name and description. It rewrites the envelope only. It does not validate that the schema is a good tool description. |
estimate_tokens | Estimate input tokens for a text and the USD list-price cost across the models in the Agent Toolbox price table (verified 2026-11-07). The count is a rough heuristic (about 4 characters or 1.3 words per token), not a provider tokenizer. Use it to compare models before a run. It does not call a… |
mcp_config | Build a generic mcpServers JSON object for one local stdio command or one remote URL. Client-specific files (Claude Code type, VS Code servers, Codex TOML) are documented on /tools/mcp. This tool does not contact the server. |
search_directory | Search the hand-curated Agent Toolbox directory by words and category. Matching is a case-insensitive substring over the name, description, and tags. It does not crawl the web or claim a server is healthy. |
In its maker's words
Free, no-key MCP server: token estimates, JSON Schema conversion, MCP configs, tool search.
