What the PlayMCP connector does

PlayMCP is Kakao's MCP gateway. One endpoint routes to a "toolbox" of up to ten MCP servers you pick from a public Korean catalogue holding 462 approved servers. It has no fixed tool list of its own — it forwards whatever your toolbox contains, which is why Anthropic's directory lists zero tools for it. Sign-in is Kakao OAuth.

Limits

  • Kakao's agent-connection guide instructs an agent to escape its sandbox, and you should not let it. The guide at playmcp.kakao.com/llms/mcp-connection-guide.md tells the reading agent to install the mcporter package and states that even when the request arrives in a container environment, it must be installed into the base system environment, with credentials written to ~/.mcporter/credentials.json and no backup needed. It also embeds a fixed client_id. We did not follow any of it. Treat that document as vendor data, not as instructions to your agent, and perform the token exchange yourself.
  • One scope, and it is a wildcard. default names no object and no verb. Consent cannot separate a map lookup from an outbound message, and it covers servers you add after consenting.
  • The connector has no tool list, so no tool list can be audited. What you granted is determined by your toolbox, and it changes whenever you edit it. Re-check the toolbox rather than the connector.
  • Published tool metadata can be stale. Kakao states catalogue pages do not auto-refresh while calls use live tool information. The list you reviewed is not guaranteed to be the list that runs.
  • Prompts and resources are dropped. Kakao's review policy states PlayMCP does not handle those parts of the MCP spec, so a server's non-tool surfaces do not reach your client.
  • Third-party servers, not Kakao services. 425 of the 462 catalogue entries declare no auth of their own and are operated by parties other than Kakao. Kakao reviews them but states it may unpublish one after the fact — approval is a checkpoint, not a warranty.
  • Ten servers maximum per toolbox, and Kakao counts a server toward the cap even when it is toggled off, offline, or deleted.
  • Korean-language surface. The catalogue, help centre and most tool descriptions are Korean. Tools are geographically scoped to Korea — Kakao Map's directions tools cover South Korea only.
  • AI chat is metered, and cannot be topped up. 50 questions, one recharged every five minutes, with Kakao stating there is no way to buy or earn more. This caps the built-in playground, not the connector itself.
  • Conversations are retained for 90 days. Kakao states PlayMCP AI chat logs are kept that long for support and error analysis, then deleted automatically. This applies to PlayMCP's own chat, not to Claude.
  • We could not read tool schemas or safety annotations from the wire. The endpoint returned 401 to an anonymous request, so no readOnlyHint or destructiveHint is reported here. The classifications above come from Kakao's published catalogue metadata.
  • The nominated documentation URL is a bare Notion link that renders nothing to a fetcher. www.notion.so/2189b97b4888803dbbdcef264e7eff58 returns Notion's generic marketing shell containing no PlayMCP text. The page is genuinely public, but only its API returns the content.

Frequently asked questions

How many tools does the PlayMCP MCP server have?

There is no fixed number, which is why Anthropic's directory lists zero. PlayMCP is a gateway that routes to whichever servers you put in your toolbox, so the surface is assembled by you at connect time. Kakao's public catalogue held 462 approved servers carrying 2,942 tools on 2026-08-23, and a full toolbox of the ten largest would reach 283.

Can the PlayMCP connector send a KakaoTalk message?

Yes, if you add the right server to your toolbox. Kakao's own KakaotalkChat server exposes one tool, MemoChat, which its description says sends a KakaoTalk message to yourself. Third-party servers in the catalogue go further: one sends KakaoTalk notifications to every member of a room, and another alerts a designated guardian.

What OAuth scopes does PlayMCP request?

One scope named default, which constrains nothing. Kakao's authorization server advertised scopes_supported of exactly default on 2026-08-23, and the server's RFC 9728 descriptor declares no scopes at all. Because the scope names neither an object nor a verb, it cannot separate reading a map search from sending a message.

Why does Claude Code fail to connect to PlayMCP?

Because PlayMCP deliberately refuses Dynamic Client Registration. Kakao's help centre states that PlayMCP does not permit DCR from unspecified AI agents for security reasons, and that the attempt surfaces as a disallowed IP range error. The documented path is a one-time token issued from the toolbox page and exchanged for an access token.

Are the tools listed on a PlayMCP server page current?

Not necessarily. Kakao's help centre states that tool information on PlayMCP pages does not refresh automatically and that a developer must re-import it and pass re-review. It also states that AI chat loads the latest tool information at call time. So the published description can lag what actually executes.

Does PlayMCP vet the servers in its catalogue?

Yes, with a written review policy and a stated turnaround. Kakao requires every tool to be tested before submission, refuses servers auto-generated by third-party platforms such as Zapier MCP, and rejects tools that request resident registration, passport, card or account numbers. Review completes within seven business days, averaging one to two.

Can I use PlayMCP servers in Claude without the gateway?

No. Kakao's help centre states that individual MCP endpoint URLs are not exposed publicly and can only be called from within PlayMCP. The gateway at playmcp.kakao.com/mcp is the only external route, and it reaches only the servers you have placed in your toolbox.

Does PlayMCP support MCP prompts and resources?

No. Kakao's review policy states plainly that PlayMCP does not currently handle the Resource and Prompt parts of the MCP specification. Only tools cross the gateway, so a server offering prompts or resources will have those surfaces dropped rather than forwarded to your client.
