Ultra Prompt MCP Server — Your prompt library, inside your AI

Stop pasting prompts. Let your AI fetch them.

MCP (Model Context Protocol) is the open standard that lets an AI assistant call external tools. Point yours at Ultra Prompt and it gains five new abilities — search your template library, read a template's fields, assemble a finished prompt, suggest curated vocabulary, and recommend the next step in your workflow. All without you ever leaving the chat.

Command legend

Eight tools, one connection

You don't type these — just talk naturally and your assistant picks the right tool. Here's what each one does and the kind of thing you'd say to trigger it. Tools marked PRO need an Ultra Prompt Pro account.

Tool	What it does	Just say to your assistant…
`search_templates`	Finds the right template across 1,000+ professionally engineered prompts.	"Find me an Ultra Prompt template for cold outreach"
`get_template`	Reads a template's fields — every input, type, and option — so it knows what to ask you.	"What details does that template need?"
`build_prompt`	Assembles the finished prompt — optionally upgraded with a reasoning framework, quality guards & output format. Stamped "Built with Ultra Prompt."	"Build it as a report, first-principles style, no fabrication"
`list_enhancements`	Lists the pro upgrades for build_prompt: 12 reasoning frameworks, 5 quality guards, and output formats.	"What frameworks can you apply?"
`suggest_vocab`	Pulls curated, expert vocabulary for any field, with plain-English definitions.	"What are good options for the style field?"
`recommend_next`	Suggests the natural next templates in your workflow, via the template genome.	"What should I make after this?"
`build_pipeline` PRO	Chains several templates into one multi-step mega-prompt (like Power Creator).	"Chain these into a 3-step content pipeline"
`save_playbook` PRO	Saves a workflow to your account — it appears in your web-app Playbooks tab, ready to run or edit.	"Save that as a playbook called Weekly Content"

✦ Not just templates — pro-grade prompts

Ask your assistant to apply Ultra Prompt's 6 frameworks (RTCEE, CO-STAR, RACE, RISEN, APE, BROKE), quality guards (no fabrication, cite sources, flag assumptions…), and output formats — the same controls power users get in the web app. It even auto-applies the best framework for each template — just say "use the recommended framework." These upgrades, plus Pipelines & Playbooks, are Pro features.

Questions

Good to know

What exactly is MCP?

The Model Context Protocol is an open standard for connecting AI assistants to external tools. When you add the Ultra Prompt MCP server, your assistant can call our prompt library directly — like giving it a new set of skills.

Do I need an account?

Yes — a free Ultra Prompt account is required to generate a key. That's how we keep the service abuse-free and tie usage to you. Free accounts get 5 tool calls per month; Pro is unlimited.

Which clients work?

Any client that supports remote (HTTP / Streamable) MCP servers — Claude Code, Claude Desktop, claude.ai, Cursor, and a growing list of others. Same URL and key everywhere.

Is my key safe to share?

Treat it like a password — anyone with it uses your monthly allowance. You can revoke and regenerate it anytime from Account → MCP Server if it ever leaks.

Does it cost extra to run prompts?

No. The MCP server assembles prompts from your template library — there's no AI inference on our end, so it's just the tool calls counting toward your monthly allowance.

Bring Ultra Prompt everywhere you work.
