"Understanding Abstract Syntax Trees (AST)" matching MCP servers:

Enables AI to execute registered system commands across platforms using a stable program + args interface, without requiring shell-specific syntax or tool discovery.

An enhanced Model Context Protocol filesystem server that fixes common limitations and adds features like glob pattern search, head/tail reading, intelligent file editing with syntax validation, and new tools for delete and command execution.

An MCP server for driving an ITS session on a PiDP-10 emulator over raw TCP, supporting persistent connections, raw control-byte transmission, and escape syntax for DDT commands. It enables interaction with ITS systems through natural language via MCP tools like open, send, read, and status.

macctl is an accessibility-first macOS desktop automation MCP server that lets AI clients see the screen, inspect app accessibility trees, control mouse/keyboard, manage windows, and run commands, all behind tiered permissions and audit logging.

Validate any shell command before execution. AI agents call Check to know if a command will work before running it: returns runnable or invalid. $0.04 AUD per check.

Turns Markdown files into local MCP servers, enabling users to define and run tools using simple Markdown syntax with zero dependencies.

Enables a local Windows developer agent to perform atomic filesystem operations, validated AST-based code edits, PowerShell/CMD process execution, and durable SQLite-backed background jobs with system diagnostics. It can run either as a loopback Streamable HTTP server or over an outbound encrypted OpenAI Secure MCP Tunnel with a local supervisor control panel.

Enables autonomous AI agents and MCP clients to route tool calls through a zero-trust firewall that blocks dangerous shell commands, redacts secrets and PII, restricts sensitive file access, and logs verdicts. It provides an MCP interceptor decorator to protect MCP server tools with AST-based command injection checks and allow, block, or redact decisions.
