Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@mcp-datetime How many days until December 25?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.

Scored across 10 tools
Most tools have distinct purposes, but date_diff, countdown, and business_days all involve date differences, creating potential confusion. Descriptions help clarify boundaries, but the overlap between date_diff and countdown remains somewhat vague.
Tool names use a mix of verb_noun (convert_timezone, format_date, explain_cron), noun phrases (date_math, unix_timestamp, business_days, countdown, date_info), and a bare keyword (now). No consistent convention is followed.
10 tools is well-scoped for a datetime utility server, covering current time, conversions, arithmetic, formatting, business days, and cron explanation without unnecessary bloat.
The set covers most core datetime operations, but lacks a general date string parser (only unix_timestamp converts to/from ISO) and business_days excludes holidays, not just weekends. These are minor gaps that agents can work around.
MCP server for your apps' tools and custom tools, plus hosted AI agents and approval-gated workflows
MCP server connecting AI agents to 100+ apps (Gmail, Slack, Notion, GitHub) via one-click OAuth.
The Remote MCP server acts as a standardized bridge between LLM applications (like Claude, ChatGPT, and Cursor) and external services, enabling AI agents to access external tools and resources. Its primary capability is providing a centralized search tool to discover other MCP servers and their respective tools. Unlike local implementations, it runs remotely with OAuth authentication and permission controls for security.
MCP server unifying ERPs, CRMs, APIs and knowledge base for Claude, ChatGPT and Gemini.
