How it works
- 01
Pick an agent below
Choose the AI tool you already use. MCP clients get a ready-made config block; the ChatGPT page uses REST API Actions instead.
- 02
Drop one MCP config block
Paste the snippet into your MCP client's config, or run its add command. No key is needed to start: the agent connects your workspace through a browser approval.
- 03
Your agent works the inbox
The agent can use only the tools allowed by your plan, API-key scopes, connected channels, and rate limits. Write actions remain unavailable to read-only keys.
What your agent can do
- List and read conversations and contacts
- Send messages and WhatsApp templates (paid plans)
- Create keyword automations and reply to comments
- Validate and submit WhatsApp template drafts
- Dry-run and trigger journeys
- Explain a delivery error code in plain English
Plans and access
The server exposes 60 tools, 11 prompts, and two resources. Free workspaces get read-only access. Creator does not include MCP. The MCP plans (MCP Starter, MCP Growth and MCP Pro) are built for bringing your own agent and model: they include the MCP tools but no InstantReply-hosted AI replies. Starter, Growth, Pro, and the three Developer plans include the full tool set, limited by key scopes and rate limits. WhatsApp automation needs Growth or Pro, or the 7-day Pro trial. See the plan table.

MCP server questions
What is the InstantReply MCP server?
It is an MCP server that lets an AI client read your InstantReply inbox and, on paid plans, act on it. It exposes 60 tools and 11 prompts covering conversations, contacts, channels, comments, WhatsApp templates, journeys, analytics, and approvals.
Do I need an API key?
No. Add the server to your client with no key, ask the agent to connect InstantReply, and approve the short code in your browser. The key is then saved on your machine. You can also paste a key from the dashboard.
Which plans include MCP?
Free workspaces get read-only tools. Creator does not include MCP. The MCP plans (MCP Starter, MCP Growth and MCP Pro) are built for bringing your own agent and model: they include the MCP tools but no InstantReply-hosted AI replies. Starter, Growth, Pro, and the Developer plans include the full tool set. WhatsApp automation needs Growth or Pro, or the 7-day Pro trial.
Does ChatGPT use the same server?
ChatGPT can use the remote connector at api.instantreply.co/mcp, or a Custom GPT with REST Actions. The other clients run the server locally with npx or connect to the remote URL.

Don't see your tool?
Any MCP-compatible client works.
The server speaks plain MCP over stdio, and the same tools are available over the remote endpoint. If your tool can run an npx command or add a remote MCP URL, it can use InstantReply.
