Directory MCP
Find MCP servers
from inside your agent.
One MCP endpoint searches the PlugMCP directory of MCP servers and agent skills. Your agent gets ranked results, health and auth signals, and the install config for its client. No key needed to start.
https://plugmcp.ai/mcp-server
Install
Add it to your agent
Paste one of these. It works without a key; to raise the limit, add Authorization: Bearer <key> with a key from your dashboard.

Add a custom MCP server called plugmcp-directory at https://plugmcp.ai/mcp-server. If it needs a sign-in, show me the connect card.ChatGPT
In ChatGPT, open Settings, then Connectors, and add a custom connector with the URL https://plugmcp.ai/mcp-server. It uses the no-key tier.

- get_server
- Details for one server by slug: description, tools, auth, transport, health, packages, and links.
- get_install
- The exact config or command to install one server in one client: Cursor, Claude Code, Claude Desktop, VS Code, Windsurf, ChatGPT, Codex, Gemini CLI, Grok Build, Grok Bot, or plain JSON.
- list_categories
- Directory categories with listing counts.
- whats_new
- Servers added to the directory recently, best first, plus health changes.
- compare_servers

Limits
Free to start, more with a key
No key: 20 calls a day
Counted per address, at most 5 a minute and 10 an hour. Compact results, ten per page. Enough to try it, and what ChatGPT uses.
Free key: 400 calls a day
Sign up, create a directory key on the dashboard, and send it as a Bearer header. Up to 15 a minute and 60 an hour, with every field, including install configs in search results.
Paid plan: 20,000 a day
Any paid PlugMCP plan. Up to 300 a minute with no hourly cap, fifty results per page, and still served when the directory is busy.
Keys stay hashed
A key is shown once. We keep only its hash, and checking it never leaves the directory database.
FAQ
Questions
Do I need a key?
No. Without a key the directory MCP answers 20 tool calls a day per address, with compact results. A free PlugMCP account key raises that to 400 a day with every field, and a paid plan to 20,000.
Why can't I use the whole day at once?
Every tier is paced so one busy agent cannot take the server from everyone else. No key: 5 calls a minute and 10 an hour. Free key: 15 a minute and 60 an hour. Paid: 300 a minute with no hourly cap. When a limit is hit, the tool result says which one and when it resets. Repeated searches are answered from a cache, so they are fast.
How do I send the key?
As a header: "Authorization: Bearer <key>". Create the key on the PlugMCP dashboard. It is shown once and only its hash is stored.
Does it work in ChatGPT?
Yes, as a remote connector with the URL above. ChatGPT cannot send a key header, so it uses the no-key tier.
Does it work in Grok Bot?
Yes. Send "Add a custom MCP server called plugmcp-directory at https://plugmcp.ai/mcp-server" in a Grok Bot chat and confirm the card. Every Bot on your account gets it. Ask it for a server with client grok-bot and it returns the message that adds that server too, and get_skill returns the message that installs a skill.
Does it install or run servers for me?
It finds them and returns the install config for your client. The servers themselves run at their publishers, not on PlugMCP.
What does it log?
One line per tool call in our server logs (the tool, the search words, timing and an address hash that changes daily) and daily totals in the directory database. Nothing about a call is written to our account database.
The directory MCP also has its own listing: PlugMCP Directory. New to it? Read the step-by-step guide. Prefer a browser? Browse the directory.
