v0.5.3: The Security-First & Token-Slimming Milestone

🚀 What's New in v0.5.3

• Zero-Trust Host Authorization Guardrail (#56): Enforces secure-by-default host authorization requiring explicit allow_hosts to prevent AI agents from probing unauthorized SSH infrastructure.
• Token & Quota Impact: Slashes context window consumption by 98.8% using concise, structured telemetry summaries instead of raw terminal dumps.
• MCP Registry Official Ownership Verification: Added visible mcp-name: io.github.sandbanks/agentic_ssh metadata for automated registry sync.
• Multi-Architecture Linux & Nix CI: Native Linux ARM64 (aarch64-linux) support and automated Cachix binary cache distribution.
• Sponsorship & Sandbanks VIP Integration: Enabled GitHub Sponsors and private VIP community integration.

v0.4.10

What's Changed in v0.4.10

🚀 Highlights & Features

• MCP Tool Discovery (agentic_ssh tools): Added a dedicated CLI command (and alias agentic_ssh list-tools) to inspect all built-in and dynamically registered custom MCP tools, parameter types, requirements, and descriptions in human-readable terminal format or machine-readable JSON (--json). (#50)
• Nix Flake & Cachix Binary Cache: Added first-class Nix packaging with flake.nix for zero-compile instant execution (nix run github:sandbanks/agentic_ssh), devShells, and automated binary uploads to sandbanks.cachix.org. (#52, #53)
• Bounded Connection Timeouts & OpenSSH ConnectTimeout: Added configurable connect_timeout_secs, native OpenSSH ConnectTimeout parsing from ~/.ssh/config, guarded async handshakes / agent auth, and single-host execution timeout parity. (#51)
• Command Execution Timeouts: Added timeout_secs option to run_command for bounded remote execution.

v0.4.9

What's Changed

🚀 Dependency & Engine Upgrades

• Upgrade core SSH library russh to 0.63.1 (using ^0.63 in Cargo.toml)
• Adapt ClientHandler::check_server_key to accept &russh::keys::PublicKeyOrCertificate for russh 0.63 compatibility (#49)
• Refresh transitive crypto and utility dependencies (aws-lc-rs, rustls, thiserror, uuid)

📖 Documentation

• Update MCP Toplist badge URL to io.github.sandbanks/agentic_ssh

Full Changelog: v0.4.8...v0.4.9

v0.4.8

Update MCP Registry verification metadata.

v0.4.6

Add MCP Registry verification metadata.

v0.4.5

🚀 Features & Enhancements

1. agentic_ssh clean Subcommand & Log Storage Telemetry

• New clean Subcommand: Purge session telemetry log files from ~/.agentic_ssh/sessions.
• agentic_ssh clean: Deletes logs older than 3 days by default.
• agentic_ssh clean --numdays N / -n N: Deletes logs older than N days.
• agentic_ssh clean --all / -a: Deletes all session logs regardless of age.
• Configurable Retention: Set a custom default retention period in ~/.config/agentic_ssh/config.toml or .agentic_ssh.toml using clean_days = 5 (or alias log_retention_days = 5).
• Log Telemetry in agentic_ssh doctor: doctor now features a Session Logs & Storage health check section showing total log file count, disk usage, and a breakdown of reclaimable space for logs older than 2, 3, and 7 days.

2. ANSI Color Rendering in watch Logs

• Log viewports in agentic_ssh watch now parse and render ANSI escape sequences natively using ansi-to-tui.

• Terminal color codes (e.g. \x1b[1;34m...) are displayed as rich colored text in both live grid view and post-execution split-pane inspection view instead of raw escape strings like ^[[1;34m.

🐛 Bug Fixes & CLI Output Refinements

3. Clean JSON Output for agentic_ssh json

• MCP Envelope Unwrapping: agentic_ssh json <tool> now unwraps inner JSON text payloads from the MCP CallToolResult response wrapper, producing clean JSON directly pipeable into jq.

• Silenced Connection Telemetry: Suppressed SSH connection logs (Connecting to..., Trying agent key...) and progress tickers when invoking tools via agentic_ssh json.

• run_command quiet Default Fix: Corrected the default value of the quiet argument in run_command from false to true, matching tool schema documentation and preventing raw stdout stream chunks from leaking onto console outputs.
