merge of MCP configuration files #28
Description
Currently, the config resolution will take the first file found in this order:
MCP_CONFIG_PATH environment variable
-c/--config command line argument
./mcp_servers.json (current directory)
~/.mcp_servers.json
~/.config/mcp/mcp_servers.json
Sometimes I want to use both my personal MCP servers and the project's MCP servers. E.g. I might want the AI agent to write a task to my personal Todo app (say Todoist) so I remember to work on this Playwright issue. I would prefer to store the Todoist MCP in my user config (e.g. ~/.config/mcp/mcp_servers.json), but the Playwright MCP is project-related and shared between my teammates and would go into the workspace config (e.g. ./mcp_servers.json). This currently cannot be done.
Is it possible to implement a merge of the configuration files instead? Same-named ones would be overwritten (which would cater for MCP hiding, e.g., my personal GitHub MCP can be hidden by my company's GitHub MCP).
