Connect the PromptSpace MCP

Add the PromptSpace Model Context Protocol server to Claude, ChatGPT or Claude Code once; after that, any skill on this site becomes a one-line paste away. No account, no payment, read-only, open-standard.

How to add the PromptSpace Agent Skills Library

What is an MCP? A one-time connection that lets Claude or ChatGPT read our skills library — like a library card. Without it, your assistant has never heard of a skill like PS01, so it guesses. With it, pasting a skill's starter prompt hands your assistant the real procedure and reference material behind that skill. You add the connection once; it stays there for every skill on this page.

Copy the MCP address

You'll paste this into Claude or ChatGPT in step 2.

Paste it into Claude or ChatGPT

Add to Claude

Or manually: open Claude → Settings → Connectors → Add custom connector → paste the address → Add. Nothing to sign in to. Then in a chat, open the + menu → Connectors and switch it on. Free accounts hold one custom connector. Desktop, mobile and Claude in Chrome pick it up once added on the web. On Team / Enterprise, an Owner adds it under Organization settings → Connectors.

Paste a starter prompt

Back in the chat, paste any skill's starter prompt below. That one line is all it takes — it fetches the real skill and hands the chat over. Every skill below has its own line, ready to copy.

Start PS01 using the PromptSpace Agent Skills Library.

Verify the connection

Once added, in a new chat ask: "Using the PromptSpace MCP, list the first 5 skills."The assistant should return a real list of skill IDs and names. If it hallucinates names like "AC21" that aren't on our library, the connector isn't active in that chat.

Security & privacy

Read-only. The server exposes no write, no account, no file-system or outbound-network tools.
No authentication required and no cookies set. The server does not know who you are.
Only public skills (isPublic: true) are reachable; private skills are filtered server-side.
Slug and ID lookups are validated against a strict regex before any filesystem access — path traversal is not possible.
Rate limited at the Cloudflare edge; abuse → IP block, not an account block.

FAQ

What is MCP?

MCP (Model Context Protocol) is an open standard from Anthropic that lets AI assistants talk to external tools and data sources through a single consistent connector. The PromptSpace MCP exposes read-only access to our skill catalogue so a connected assistant can resolve a skill ID (e.g. PS01) to the real skill content on demand.

Do I need an account to use the PromptSpace MCP?

No. The MCP server is public, read-only, and requires no authentication. Point any MCP-compatible client at https://www.promptspace.in/mcp and it works.

Which assistants support MCP?

Claude Desktop (Plus/Pro/Team/Enterprise), Claude Code (CLI), and ChatGPT in Developer mode on web (Plus/Pro/Business/Enterprise/Edu). Cursor, Codex, Zed and other MCP-compatible IDEs also work.

Why do I see a security warning when adding the connector?

Both Claude and ChatGPT warn that custom MCP servers can read your conversations in the chats where they are enabled. That warning is standard. The PromptSpace MCP is read-only — no write operations, no account data, no tracking.

The assistant says it does not know the skill I asked for.

Three fixes. 1) In Claude, open the chat's + menu → Connectors and make sure PromptSpace is switched on for this chat. 2) In Claude Code, run /mcp and reconnect. 3) Reload the chat; some clients cache the tool list for a few minutes after first connect.

Can I redistribute PromptSpace skills?

Yes. All public PromptSpace skills are licensed under CC-BY-4.0 unless the skill states otherwise. Keep attribution to PromptSpace and link back to the canonical skill URL at promptspace.in/skills-library/<slug>.

Is there a self-hosted or offline option?

Not yet. The MCP server is hosted on promptspace.in. If you need offline access, open the individual skill's page and save the SKILL.md body — it is a plain markdown file.
