MCP (Model Context Protocol) Integration

ChatPRD works inside the AI tools you already use. In ChatGPT, Cursor and Grok Bot, install the ChatPRD app or plugin. In Claude Code, Codex, Claude, Claude Cowork and any other tool that supports remote MCP, connect ChatPRD's hosted MCP server. Either way you sign in with your ChatPRD account, and there's nothing to install locally and no API key to copy.

Overview

• Server URL: https://app.chatprd.ai/mcp. You'll also find it in ChatPRD under Settings > Integrations > MCP.
• Sign-in: OAuth. The first time your tool connects, it opens a ChatPRD sign-in in your browser.
• Plans: public templates work for anyone, without signing in. Everything else needs a Pro, Team or Enterprise plan (trials included).

Set up your tool

ChatGPT

1. Open ChatPRD in the ChatGPT apps directory.
2. Click to add the app, and sign in to ChatPRD when asked.
3. In any chat, pick ChatPRD from the composer to use it.

Cursor

1. Open ChatPRD in the Cursor Marketplace and install it, or type /add-plugin chatprd in Cursor's agent chat.
2. Sign in to ChatPRD the first time Cursor connects.

The plugin sets up the MCP server for you and adds skills for working from your specs: write-prd (write a PRD from your codebase), implement-from-prd (plan an implementation from a PRD), check-prd-alignment (check your branch against the PRD) and update-prd (update the PRD to match what you built).

Grok Bot

1. In Grok Bot, open Connect Apps and search for ChatPRD.
2. Install the ChatPRD plugin and sign in to ChatPRD when asked.
3. Type @ in a task to attach ChatPRD.

Claude Code

Run this in your terminal:

claude mcp add --transport http chatprd https://app.chatprd.ai/mcp

Then start Claude Code, run /mcp, select chatprd, and sign in to ChatPRD in your browser.

Codex

Run these in your terminal. The login command opens your browser to sign in to ChatPRD.

codex mcp add chatprd --url https://app.chatprd.ai/mcp
codex mcp login chatprd

The server is saved to ~/.codex/config.toml and works in the Codex CLI and the IDE extension.

Claude and Claude Cowork

Claude on the web, Claude Desktop and Claude Cowork share the same connectors, so you only add ChatPRD once.

1. In Claude, open Customize > Connectors.
2. Click + Add > Add custom connector, name it ChatPRD, and paste https://app.chatprd.ai/mcp.
3. Click Connect and sign in to ChatPRD.

On Claude Team and Enterprise plans, an owner adds the connector under Organization settings > Connectors first.

VS Code

Add this to .vscode/mcp.json in your workspace, or run MCP: Open User Configuration to add it for every workspace:

{ "servers": { "ChatPRD": { "type": "http", "url": "https://app.chatprd.ai/mcp" } } }

Start the server from the file, and sign in to ChatPRD when VS Code asks.

Any other MCP client

ChatPRD works with any tool that supports remote MCP servers over HTTP with OAuth. Add a remote server with the URL https://app.chatprd.ai/mcp, and sign in to ChatPRD when prompted. For example, in Grok on the web, go to grok.com/connectors, click New Connector > Custom, and paste the URL.

Available MCP tools

Public templates (no sign-in needed)

• list_public_templates: browse ChatPRD's public templates, such as the PRD, AI development brief, user testing plan and launch checklist.
• get_public_template: get a template's full structure.

Your documents

• list_documents, get_document, search_documents: find and read your documents.
• create_document, update_document: write documents with the content you provide.
• list_templates: list your templates.
• list_projects, list_project_documents: browse projects and their documents.
• list_chats, search_chats: find your ChatPRD chats.
• list_user_organizations, list_organization_documents: browse your team's documents.
• get_user_profile: read your profile.

AI document generation

• ai_create_document: ask ChatPRD's AI to write a new document.
• ai_edit_document: make targeted edits to a document.
• ai_rewrite_document: rewrite a document.
• get_document_generation: check on a generation that's still running.

The AI tools wait up to about 50 seconds for the document. If it isn't finished, they return a generation ID that your tool checks with get_document_generation. Each generation runs in a ChatPRD chat you can continue in the app. See AI document generation.

Meta Muse

Meta's Muse agent connects through the ChatPRD API instead of MCP.

1. In ChatPRD, go to Settings > Integrations > Meta Muse.
2. Create an API key (it's named "Meta Muse" by default). Copy it right away; it won't be shown again.
3. Point Muse at ChatPRD: store the key in Muse as the credential CHATPRD_API_KEY, and give Muse the setup prompt shown on the page.

See Meta Muse setup and API keys.

Troubleshooting

Your tool can't connect

• Check that the server URL is exactly https://app.chatprd.ai/mcp.
• Make sure your tool supports remote MCP servers over HTTP. Older setups that run the server locally through npx mcp-remote aren't needed anymore.
• Restart your tool after changing its configuration.

"Sign in to ChatPRD to use this tool"

• Every tool except the public template tools needs you to sign in. Reconnect ChatPRD in your tool and finish the browser sign-in.

"This ChatPRD tool is included with Pro, Team, and Enterprise plans"

• Account tools need a Pro, Team or Enterprise plan, or a trial. Check your plan in Settings > Billing.

ChatPRD's MCP server is hosted, with sign-in handled by our auth provider, Clerk. If you have trouble connecting a tool, see Clerk's MCP documentation.

Security

• MCP connections use HTTPS.
• You sign in with your ChatPRD account; no credentials are stored in your tool's configuration.
• All data follows ChatPRD's standard security practices. See Security and Privacy.
