[Bug] MCP tools invoked as Bash commands instead of proper tool calls

Bug Description
Context7 works fine from here. The issue you saw was a bug in the other session where Claude incorrectly tried to run mcp__context7__resolve-library-id as a Bash command instead of using the MCP tool properly.

Summary of what went wrong in that session:

1. Permission prompt appeared (shouldn't have - it's in your allow list)
2. Claude tried to run MCP tool as Bash command: Bash(mcp__context7__resolve-library-id --libraryName "...")
3. Obviously failed with "command not found"
4. Then Claude gave up saying "Context7 isn't available"

This is a Claude Code bug - MCP tools should never be called via Bash.

Your current setup should be correct - Context7 is working in this session. If you keep seeing permission prompts in other projects, you may want to add to your project-level .claude/settings.json:

{
"permissions": {
"allow": [
"mcp__context7"
]
}
}

The mcp__context7 (without tool suffix) should auto-approve all tools from that server.

Was there something specific you wanted to do with Context7/ky, or were you just reporting this bug?
