Add diagnosable web and platform access to a coding Agent

Agent Reach is an open-source capability layer for a coding Agent. Rather than recreating every scraper, it selects upstream tools for web pages, YouTube, GitHub, RSS, X, Reddit, Xiaohongshu, and other platforms, installs dependencies, checks health, and can use fallback routes where available.

What “supported” actually means

Public web pages, YouTube captions, RSS, and public GitHub repositories have zero-configuration or lower-setup paths in the current upstream channel matrix. Semantic web search connects through MCP. Other channels can need credentials or another tool: private GitHub work needs gh sign-in; X needs cookies or a browser session; Reddit needs desktop OpenCLI or cookies; Facebook and Instagram use browser sign-in; Xiaohongshu needs an existing Chrome session or exported cookies; LinkedIn detail work depends on MCP or browser automation.

Install support does not mean immediate access. agent-reach doctor checks whether a command and the chosen path actually work, then reports repairs. That matters when anti-bot controls or an upstream dependency changes.

Safer first workflow

Read docs/install.md, run the default check or --dry-run, inspect Python, Node.js, CLI, and MCP changes, and only use --system after accepting them. The default agent-reach install checks the environment without automatically installing system packages or writing configuration. Validate no-login channels first. Use dedicated test accounts for cookie-dependent platforms.

Cookies can carry full login authority. A leak can expose a session, and automated behavior can trigger limits or account suspension. Even when stored locally, assess file permissions, backups, logs, and other local programs. "Zero API fees" also does not mean zero cost: proxy, installation, maintenance, accounts, and failure handling remain. Respect platform terms, copyright, personal-data rules, and local law.

Source and license

Platform login and retrieval paths can change with anti-bot controls. Run agent-reach doctor after installation or updates to see the backend and current status for each channel.
