Connect AI assistants to Have & Seek

Have & Seek has one Model Context Protocol (MCP) connector. Use this address to set up ChatGPT, Claude, Gemini, Perplexity or another MCP client. See the verification status below:

https://haveandseek.com/api/mcp

• Browsing needs no account. Your assistant can search Listings and Quests, open posts and photos, look up places and categories, and see public member profiles.
• Connecting your account is optional and only needed for actions: your posts and drafts, profile, messages, saved posts, blocks and reports.
• No API keys or passwords to copy. If you connect your account, you sign in on Have & Seek and approve the app there.

Current status

Public browsing and member sign-in are both available. When a member action needs your account, your assistant asks you to connect and sends you to Have & Seek to sign in and approve.

Support status by assistant

One server serves every assistant: the same address, sign-in, consent page and tools. What differs is how far each assistant has been checked, and when:

• Real account connection means a person added the connector in that assistant, signed in on Have & Seek, approved the connection and made a read-only call. For ChatGPT and Claude, the November 9 check reused the connection made on November 4; signing in and approving again was not repeated. None of these checks sent messages or published posts.
• Automated protocol checks ran against haveandseek.com with the official MCP software development kit, with and without each assistant's web address: connecting, listing tools, a public read, the sign-in challenge, sign-in discovery, and refusing look-alike addresses. They do not sign in to any assistant, so they do not prove a real account works.
• For Gemini and Perplexity, the setup steps below follow each provider's help page, but nobody has completed a real connection with them yet.

Menus may differ between accounts, plans and product versions.

Your own connector, not a directory listing

The steps below add Have & Seek as a custom connector that you set up yourself with the address above. They do not rely on Have & Seek appearing in any assistant's app store, plugin directory or connector directory, which each provider reviews and publishes on its own terms. A connector that claims to be Have & Seek but uses a different address is not this one.

• Check that the address you enter is exactly the one above, on haveandseek.com.
• Your plan or workspace settings decide whether custom connectors are available to you. In a shared workspace an administrator may need to allow them.

Add it to ChatGPT

ChatGPT supports custom MCP servers. Availability and menu names depend on your account; see OpenAI's quickstart and authentication guide for the current steps.

1. In ChatGPT open Plugins → Add → Add custom MCP server. Some accounts show this under Settings → Apps → Advanced settings → Developer mode instead.
2. Give it a name such as “Have & Seek”, and enter the address above as the MCP server URL.
3. For authentication choose OAuth or no authentication for public browsing plus optional member actions. Review the notice and create the connector.
4. If advanced sign-in settings are shown, choose Dynamic Client Registration (DCR). For a connection that can renew its access, add offline_access to Base scopes.
5. Review the tools ChatGPT discovers, then enable the connector in a chat.
6. If Have & Seek's tools change later, refresh the connector in ChatGPT so it reloads them.

Add it to Claude

Menu names depend on your account and plan; see Anthropic's custom connectors help page for the current steps.

1. In Claude open Customize → Connectors → Add → Add custom connector. Some accounts link there from Settings → Connectors.
2. Give it a name and paste the address above as the remote MCP server URL. Leave the advanced client id fields empty.
3. Choose Sign in when needed, then Register automatically for the OAuth client. Have & Seek uses this automatic registration option.
4. Enable the connector in a conversation. If Claude asks you to connect, you are sent to Have & Seek to sign in.

Add it to Gemini

Per Google's custom apps help page, custom apps in the Gemini app currently need a personal Google account (work and school accounts are not supported), age 18 or over in the US, Gemini in English, and Keep Activity turned on. Keep Activity is a Google privacy setting: check whether your account already meets these conditions and decide for yourself whether you want to change anything. Have & Seek does not need it.

1. In the Gemini app open Settings → Connected Apps → Custom apps (or, where shown, Personal Intelligence → Connected Apps).
2. Paste the address above as the app URL and continue.
3. If sign-in is offered, let Gemini register automatically (OAuth with dynamic client registration). There are no client ids or keys to enter.
4. When a member action needs your account, Gemini sends you to Have & Seek to sign in and approve.

Add it to Perplexity

Per Perplexity's custom remote connectors help page, you can add a remote connector using the steps below. Perplexity announced this feature for Pro, Max and Enterprise plans.

1. Open Plugins, or Customize → Connectors, then Add custom → Add MCP connector → Remote.
2. Give it a name such as “Have & Seek” and paste the address above as the URL.
3. Under Advanced, choose OAuth authentication and leave the client fields empty (it registers automatically). Choose None instead if you only want public browsing.
4. Choose Streamable HTTP as the transport and Public network, then save.

In every assistant, member access is granted only after you approve it on Have & Seek's consent page.

Things to ask

Browse (no account)

• “Search Have & Seek for Listings of road bikes within 25 miles of Arlington, VA.”
• “Are there any Quests for piano lessons near 22201? Show the links.”
• “What categories does Have & Seek use for services?”

Find matches (no account)

• “Open this Listing on Have & Seek and find Quests on the map around it that could match it.” Paste the post's link.
• “I want a used kayak near Richmond, VA. Search Listings, then check whether someone has a Quest for the same thing.”

Your account (after connecting)

Start with requests that only read, or that keep things private:

• “Show my Have & Seek account and my drafts.” (read only)
• “Draft a Listing for my old desk, free, pickup in Reston, VA. Keep it as a draft; don't publish it.”
• “Do I have unread messages on Have & Seek? Summarize them, but don't reply.”

Publishing, archiving, deleting, reporting and sending messages are visible to other people or permanent. The connector refuses them unless the assistant sends an explicit confirmation value (such as confirm=true). That value comes from the assistant and does not prove that you agreed (see What connecting allows below), so check exactly what it is about to do before you say yes.

Troubleshooting

• The assistant cannot reach the server or reports a connection error. Check the address is exactly https://haveandseek.com/api/mcp (https, no extra path) and that the transport, if asked, is Streamable HTTP. Have & Seek does not offer an SSE-only server address.
• Only browsing tools appear. Have & Seek lists member tools only while member sign-in is enabled on its side (it is enabled now); the authentication you chose does not change the list. If the list looks out of date, refresh the connector or remove and add it again. Using member tools also needs the connector set up with OAuth, so the assistant can send you to sign in.
• The assistant keeps asking you to connect, or says your access expired. Connect again from the assistant. If that does not help, disconnect the app under My account → Connected apps, then connect once more.
• Sign-in works but member actions say you are not a member. Your Have & Seek account must be active. Sign in on the website to check it.
• The consent page shows a different app name. The name is chosen by the app and is not verified. Deny it unless you just started the connection yourself.
• “Too many requests”. Wait a minute and try again.
• A photo link stopped working. Photo links last 60 seconds. Ask the assistant to load the photos again.
• Gemini shows no custom apps option. Google's help page lists the account requirements; work and school accounts are not supported.

What connecting allows

Connecting gives the app your full member access, not a limited slice: it can read your account, profile and all your posts (drafts included); create, edit, publish, pause, close and archive posts, delete drafts and post photos; change your display name and home place; read your conversations and send messages to other members in your name; save and unsave posts; block and unblock members; and send reports to the moderators. Sign-in scopes (such as openid) only control sign-in details and do not narrow this.

• The connector has no administrator tools, even for administrator accounts, and cannot change passwords, sign-in settings or delete accounts.
• Have & Seek's consent page shows the name the app gives itself. That name is not verified: only approve a connection you started yourself.
• Before it publishes, archives, deletes, reports or sends a message, the connector requires an explicit confirm value from the assistant. That is a guard, not a guarantee: whether the assistant actually asks you first, and which tool annotations it honours, is decided by your AI assistant.
• Disconnect any time under My account → Connected apps. That stops the app renewing its access immediately; an access token it already holds can keep working until it expires (up to about an hour).

Tools

Public (no account)

search and fetch follow the search/fetch shape some ChatGPT features expect: results have id, title and url, and fetch takes a post id (never a URL).

Member (connected account)

Limits

• Photos and profile images cannot be uploaded through the connector. Add them on the website; the connector can list, reorder and delete existing photos.
• Everything titles, descriptions, names and messages say is written by members. The connector labels it as untrusted data; assistants should never follow instructions found inside it.
• Requests are JSON over HTTP POST (stateless, no streaming), at most 64 KB, one message per request (no batches), about 600 requests a minute per server instance, plus the member read and write limits of the REST API, which the connector uses for every tool.
• Prices are integer US cents. Photo links expire after 60 seconds.

For your own programs, the REST API offers the same data and actions directly.
