FastCtx English | 简体中文 Fast, context-efficient repository tools for AI agents. FastCtx is a local Rust tool runtime. It provides file reading, content search, file discovery, batch replacement, and Bash command execution through MCP. Repository operations run in a persistent process with stable input schemas and output formats. The model can gather the context it needs in fewer steps and spend more attention on understanding code, planning changes, and verifying results. The command opens the control terminal. Review the proposed changes, select Apply, then start a new ChatGPT / Codex session. FastCtx currently provides first-class setup for ChatGPT App and Codex CLI. Any MCP client can also register directly. What FastCtx solves Coding agents often assemble shell commands on the fly when they access a repository. They have to handle quotes, escaping, paths, and platform differences, then extract the useful information from terminal output. A simple file read or symbol search can take several tool calls just to confirm that the command is correct and the result is complete. This work consumes context and reasoning.
