ChatGPT MCP servers & plugins (apps, custom MCP servers)
Can ChatGPT use MCP servers, and how do you add one?
As of October 2026, ChatGPT can connect to custom remote MCP servers: OpenAI's docs describe adding one from the ChatGPT Plugins page, where it is created as a plugin. Codex (CLI and IDE) configures MCP through config.toml, and the OpenAI API supports a remote MCP tool. Plan eligibility for the ChatGPT web flow was not verified.

How to add an MCP server to ChatGPT
ChatGPT (web): custom MCP server as a plugin
- Go to chatgpt.com/plugins and select the plus button.
- Choose "Add custom MCP server".
- Enter a name and description, then paste an HTTPS URL ending in /mcp, or select a Secure MCP Tunnel.
- Configure authentication.
- Review the risk warning and select "I understand and want to continue".
- Select "Create as a plugin", then review the tools ChatGPT found.
- Install the plugin, open a new chat and pick it from the @ menu.
OpenAI's fetched docs do not state which plans can add custom MCP servers, and do not mention a "developer mode" toggle or beta label on these pages. Apps (including those built with the Apps SDK) are packaged into plugins, which can include apps, skills, or both. Searches also surfaced OpenAI Help Center articles on developer mode, but they could not be fetched, so no plan or beta claim is made here.

Codex CLI and IDE extension
- Run codex mcp add <server-name> -- <stdio server-command>, or edit ~/.codex/config.toml (or .codex/config.toml in a trusted project).
- For a remote server, add a [mcp_servers.<name>] table with a url.
- In the IDE extension: gear menu, MCP servers, Add server, choose STDIO or Streamable HTTP, save, then Restart extension.
- Run codex mcp list to see configured servers; use codex mcp login <server-name> for OAuth servers.
[mcp_servers.figma]
url = "https://mcp.figma.com/mcp"
bearer_token_env_var = "FIGMA_OAUTH_TOKEN"
http_headers = { "X-Figma-Region" = "us-east-1" }The CLI, IDE extension and ChatGPT desktop app share the same MCP setup in config.toml. Streamable HTTP supports bearer token, OAuth, and ChatGPT session authentication.

OpenAI API (Responses API remote MCP tool)
- Add a tool of type "mcp" with a server_label and server_url to a Responses API request.
- The API lists the server's tools (mcp_list_tools); narrow them with allowed_tools.
- Handle approvals with require_approval; the default is to request approval before data is shared.
Works with remote servers using Streamable HTTP or HTTP/SSE. Pass an OAuth access token in the authorization field on every request. connector_id is deprecated for models released after September 1, 2026; use server_url or tunnel_id.
Source: developers.openai.com
Before you connect
- OpenAI warns: "A malicious server can exfiltrate sensitive data from anything that enters the model's context."
- By default, the API requests approval before any data is shared with a remote MCP server; only skip approval for servers you trust.
- Adding a custom MCP server in ChatGPT shows a risk warning you must accept, and account and workspace policies apply.
- In Business and Enterprise workspaces, "Upload plugins" and "Create plugins with MCPs" are off by default and controlled by admins.
- Plan eligibility, beta status of developer mode, and write-action confirmation rules for ChatGPT web could not be verified from fetchable OpenAI pages as of October 2026.
Official hosted MCP servers you can try in ChatGPT
These vendors publish a hosted MCP server. Whether one connects to ChatGPT also depends on its sign-in method and your plan, so check its verdict page first.
Figma publishes an official MCP server. The remote server at mcp.figma.com/mcp works with Claude, Cursor and VS Code using Figma sign-in, and a desktop variant runs locally. It reads designs and generates code, and the remote server can also write to Figma files. Free-plan and View seat usage is capped at six calls per month.
GitHub publishes an official MCP server, github/github-mcp-server, available as a remote endpoint at api.githubcopilot.com and as a local Docker build. The remote server signs in with OAuth or a personal access token. It includes write tools such as merge_pull_request and delete_repository, so use read-only mode or limited toolsets.
Slack publishes an official remote MCP server at mcp.slack.com/mcp, and Anthropic lists it as a verified Claude connector made by Slack. It uses OAuth with per-tool user scopes, and workspace admins must approve the client. It can send messages and edit canvases, so review permissions before enabling.
Atlassian publishes an official remote MCP server, the Atlassian Rovo MCP server, for Jira, Confluence and other Atlassian apps at mcp.atlassian.com/v2/mcp. It uses OAuth 2.1 and is listed in Anthropic's connector directory. Jira delete and project-admin tools are off by default, and tool calls use Rovo credits.
Datadog publishes an official remote MCP server, hosted by Datadog and documented on docs.datadoghq.com. It connects to Claude, Cursor and VS Code, signs in with OAuth, and covers logs, metrics, traces, monitors and incidents. Write tools exist but require a separate org-level MCP Write Access setting.
Higgsfield documents an official hosted MCP server at mcp.higgsfield.ai/mcp on its own help center. You sign in with your Higgsfield account via the browser, with no API key, and it requires an active paid subscription. Claude's connector directory listing was not found, so it is added as a custom connector.
Linear hosts an official remote MCP server at mcp.linear.app/mcp, documented on linear.app and listed in Anthropic's connector directory as Anthropic verified. It signs in with OAuth 2.1 or a bearer token. Read-write by default, with a separate /mcp/readonly endpoint for read-only use.
Notion runs an official hosted MCP server at mcp.notion.com/mcp, and Anthropic lists it as a verified Claude connector made by Notion. It uses OAuth and works on every Notion plan, with some features limited to Business or Enterprise. It can create, edit and delete pages. The older open-source npm server is no longer maintained.
Context7 has an official MCP server published by Upstash (upstash/context7), available remotely at mcp.context7.com/mcp or locally via npx. It fetches current library documentation for coding agents. A free API key is recommended for rate limits. Caveat: the docs it returns are community-contributed, not vetted by Upstash.
Supabase publishes an official MCP server, hosted at mcp.supabase.com/mcp and open source at supabase/mcp, and it is listed in Anthropic's connector directory. It signs in with browser OAuth. The server can run SQL and migrations, so Supabase advises read-only mode and project scoping.
Salesforce publishes official hosted MCP servers (SObject Reads, Mutations, Deletes, All and others) at api.salesforce.com, reported generally available since April 2026. Admins must enable each server, and Claude connects as a custom connector via an External Client App. No directory connector was found. Salesforce's separate local DX server reaches end of life November 2, 2026.
Zapier runs its own hosted MCP server, documented on docs.zapier.com and listed in Anthropic's connector directory as Anthropic verified. It signs in with OAuth and works through Streamable HTTP. It also acts as a bridge: each tool is an action in one of 9,000+ connected apps, and each call uses two tasks.
AWS publishes an official, managed remote MCP server at aws-mcp.us-east-1.api.aws/mcp, documented on docs.aws.amazon.com and listed in Anthropic's directory as Anthropic verified. Docs search needs no sign-in; AWS API calls use OAuth or SigV4 with your IAM permissions. Read-only mode requires the SigV4 proxy.
Cloudflare publishes an official remote MCP server for its whole API at mcp.cloudflare.com/mcp, documented on developers.cloudflare.com and in github.com/cloudflare/mcp. It signs in with OAuth or an API token. Anthropic's directory lists a different Cloudflare server (Workers bindings) that the repo marks deprecated.
Snowflake offers an official Snowflake-managed MCP server, created inside your account with CREATE MCP SERVER and documented on docs.snowflake.com. It uses Snowflake OAuth, exposes Cortex Agents, Search, Analyst, SQL execution and custom tools, and enforces role-based access per tool. The older Snowflake-Labs local server is deprecated.
Excalidraw publishes an official MCP App server, hosted at mcp.excalidraw.com and in the excalidraw GitHub organization. It draws hand-drawn diagrams inline in Claude, ChatGPT, VS Code and other clients that support MCP Apps. No sign-in is required; one tool uploads diagrams to excalidraw.com for sharing.
GitLab has an official MCP server built into GitLab itself, documented at docs.gitlab.com and generally available since GitLab 19.5. Clients connect to your instance's /api/v4/mcp endpoint with OAuth or a fine-grained token, on Free, Premium and Ultimate. It includes write tools, and an admin must allow access first.
Robinhood publishes an official remote Trading MCP server at agent.robinhood.com/mcp/trading, documented in its support center, with Claude Code and Claude Desktop setup steps. It can read all your accounts and place real trades in a dedicated Agentic account. Trade approvals are off by default for external agents.
Sentry hosts an official remote MCP server at mcp.sentry.dev/mcp, documented on its own site, built from the getsentry GitHub org, and listed in Anthropic's directory as Anthropic verified. It signs in with OAuth and can be scoped to one organization or project. No read-only mode is documented.
Microsoft publishes an official Azure DevOps MCP server, both a hosted remote one at mcp.dev.azure.com and a local npm server, documented on Microsoft Learn and in the microsoft GitHub org. The remote server uses Microsoft Entra sign-in and is in preview. Claude Desktop cannot use the remote server; Claude Code needs a custom app registration.
Firecrawl has an official MCP server published by Firecrawl at firecrawl/firecrawl-mcp-server, with a hosted remote endpoint (mcp.firecrawl.dev) and a local npx option. It supports OAuth or an API key, and a limited keyless tier. Caveat: its docs instruct agents to send search feedback to Firecrawl by default.
Gmail has an official Claude connector: Anthropic's directory lists it as made by Google, pointing at Google's remote Gmail MCP endpoint (gmailmcp.googleapis.com). Google labels that server a Developer Preview and documents search, read, draft and label tools. Claude's own docs describe the connector as read-only; the directory shows more tools, so verify.
Google Drive has an official Claude connector: Anthropic's directory lists it as made by Google, pointing at Google's remote Drive MCP endpoint (drivemcp.googleapis.com). Google labels that server a Developer Preview and signs in with OAuth. Claude's directory lists share and trash tools that Google's own reference does not, so verify.
Claude's Microsoft 365 connector is built by Anthropic, not Microsoft: it reaches SharePoint, OneDrive, Outlook and Teams at microsoft365.mcp.claude.com using delegated Entra sign-in, and an Entra admin must grant consent. Microsoft separately publishes its own Work IQ MCP server for Microsoft 365 data, documented on Microsoft Learn.

FAQ
- Does ChatGPT support MCP?
- Yes. OpenAI's docs show adding a custom MCP server from the ChatGPT Plugins page, and the Codex and API products support MCP too. Which plans can do this in ChatGPT web was not verified.
- How do I add MCP to ChatGPT?
- Go to chatgpt.com/plugins, select the plus button, choose "Add custom MCP server", paste an HTTPS URL ending in /mcp, accept the risk warning, then select "Create as a plugin".
- How do I configure MCP in Codex?
- Run codex mcp add <server-name> -- <command> or edit ~/.codex/config.toml with [mcp_servers.<name>] tables. The CLI, IDE extension and ChatGPT desktop app share this setup.
- What are ChatGPT plugins now?
- OpenAI's docs describe a plugin as a package that can include apps, skills, or both, and apps connect ChatGPT to other services. The fetched pages do not say that an earlier plugin system was retired.
- Can the OpenAI API call remote MCP servers?
- Yes. Add a tool with type "mcp" and a server_url to a Responses API request; the API lists and calls the server's tools and asks for approval by default.
