[BUG]: Denied MCP tools have their tool prompt in the context
Resolved 💬 6 comments Opened Aug 22, 2025 by egalanos Closed Jan 17, 2026
I have the Sentry MCP server configured.
I have disabled a number of the tools:
"deny": [
"NotebookRead",
"NotebookEdit",
"mcp__ide__executeCode",
"mcp__sentry__analyze_issue_with_seer",
"mcp__sentry__create_team",
"mcp__sentry__create_project",
"mcp__sentry__update_project",
"mcp__sentry__create_dsn"
]
The newly add /context command reveals that the denied MCP tools are still added to the context. The denied built-in tools are not added though.
Permanently denied MCP tools shouldn't be provided to Claude.
