MCP server that visualizes agent execution flows as directed acyclic graphs (DAGs) using Mermaid diagram format
This server is fundamentally non-functional as an MCP implementation. The mcp_server.py file does not implement the MCP protocol at all, it prints a JSON status message and exits. There is no actual tool registration, no schema definitions, no parameter handling, and no request/response loop. The 'execute_skill_action' tool mentioned in the metadata is not registered anywhere in the code. The client.py and example_usage.py files are standalone Python code unrelated to MCP. This is not a working MCP server; it is a misrepresentation of what an MCP server is.
Tool for executing skill actions within the agent execution tree visualization
No actual MCP protocol implementation. The mcp_server.py file prints a status message and exits, it does not implement the MCP message loop (initialize, tool calls, responses). Agents cannot invoke any tools.
Tool 'execute_skill_action' is mentioned in metadata but not registered anywhere in the source code. No tool definition, schema, or handler is visible.
Tool description is generic and under 20 characters when expanded ('Tool for executing skill actions within the agent execution tree visualization' is ~85 chars, but tells the LLM nothing actionable: what is a 'skill action'? what does 'execution tree visualization' mean? when should this be called instead of other tools?).

No parameters documented. The tool name suggests it accepts skill action specs, but there are no parameter definitions, types, descriptions, enums, or validation rules visible in the code.
No output schema documented. LLMs cannot plan what data will be returned or chain this tool with others.
No error handling. No guidance on what errors might occur or how to recover (e.g., if an action is invalid, what should the LLM do next?).
client.py and example_usage.py are standalone Python utilities unrelated to MCP. They do not integrate with the server and cannot be invoked by MCP clients.
