pendnt — Claude Code MCP server: features and setup
Connects an agent to human approvals, notifications and inbound webhooks. Use it when actions need an explicit review or a run should send a completion signal.
claude mcp add --transport http pendnt https://api.pendnt.dev/mcpWhat pendnt does
pendnt connects Claude Code to a workspace through MCP. Its tools let an agent request or check approval, send notifications, manage inbound endpoints, schedule wake-ups and work with key-value storage. A person can review an action before the agent proceeds.
The package includes hooks for permission requests, notifications and run completion. Approval is fail-closed: errors, timeouts and operator denials prevent the action from going ahead. The hooks need PENDNT_API_KEY to call the service.
Hook scripts run on Node 18+ and use no npm dependencies. Claude Code can handle headless approvals through the PermissionRequest hook or the permission_prompt MCP tool. When both are configured, --permission-prompt-tool takes precedence.
What it helps with
- ask a person to approve an agent action
- check whether an approval request has been answered
- notify a user when a run ends
- create an endpoint for an inbound event
- schedule an agent wake-up
Example prompts for the agent
- Ask for approval before carrying out this action.
- Check whether the approval request has been answered.
- Send me a notification when the run finishes.
