Describe the Bug
hey everyone, not sure why but i’m unable to add MCP servers in codex when using cursor.
I’m trying to add 2 different MCP servers which is context7 and shadcn.
However, this errors keep showing up:
■ MCP client for shadcn-ui failed to start: program not found
■ MCP client for context7 failed to start: program not found
This is in the codex cli within cursor.
not experienced in any way and have been trying to fix it but no progress.
has anyone solved this issue?
Steps to Reproduce
[mcp_servers.context7]
command = “npx”
args = [“-y”, “@upstash/context7-mcp”]
[mcp_servers.shadcn-ui]
command = “npx”
args = [“-y”, “@jpisnice/shadcn-ui-mcp-server”]
env = { “API_KEY” = “xxx” }
This is what i added in the config
Expected Behavior
Not supposed to show errors and connected to mcp
