While attempting to use the read-resource command to troubleshoot an issue with an MCP server I am currently working on, I was seeing the following error (mcptools dev@5d86d52):

$ mcptools read-resource 'coder://user/me' path/to/my/mcp/server
Error: invalid JSON for params: invalid character 'p' looking for beginning of value

Upon closer inspection, it appears the read-resource command was trying to marshal the required commands to run the given MCP server as JSON. I could not find any reason to do this -- it seems to have been an errant copy-pasta after recent refactors? After removing it, the command worked for me. I also fixed up a couple of other things while I was in the area.

• cmd/mcptools/commands:
  • Removes errant json.Unmarshal of parsedArgs in ReadResourceCmd()
  • Adds test for ReadResourceCmd()
• pkg/jsonutils:
  • Fixes incorrect column alignment in formatGenericMap() due to colour escape sequences.
