MCP

Endpoint:

https://api.hookmyapp.com/mcp

Authentication

Choose the auth option your MCP client supports:

Sign in from your MCP client: add the server by URL and sign in when prompted (for example /mcp in Claude Code). No API key needed.
HookMyApp CLI (Claude Code): hookmyapp login configures the MCP server automatically, with no extra setup.
API key: create an API key in HookMyApp and pass it as a header.

Accepted API key headers:

Authorization: Bearer hmok_...

X-API-Key: hmok_...

Use Authorization: Bearer for bearer-token clients. Use X-API-Key when your MCP client lets you configure custom headers.

Connect

claude mcp add --transport http hookmyapp https://api.hookmyapp.com/mcp

Run /mcp, pick hookmyapp, and approve the sign-in in your browser.

HookMyApp CLI (Claude Code)

If you use the HookMyApp CLI, MCP is already configured. hookmyapp login sets it up. To repair or re-run it:

hookmyapp mcp install --agent claude
hookmyapp doctor

MCP tools load when a session starts, so restart Claude Code after installing. Until then, every operation works through the hookmyapp CLI.

API key

Set your HookMyApp API key:

export HOOKMYAPP_API_KEY="hmok_..."

codex mcp add hookmyapp --url https://api.hookmyapp.com/mcp --bearer-token-env-var HOOKMYAPP_API_KEY

claude mcp add --transport http hookmyapp https://api.hookmyapp.com/mcp \
  --header "Authorization: Bearer $HOOKMYAPP_API_KEY"

{
  "mcpServers": {
    "hookmyapp": {
      "url": "https://api.hookmyapp.com/mcp",
      "headers": {
        "Authorization": "Bearer ${env:HOOKMYAPP_API_KEY}"
      }
    }
  }
}

Use X-API-Key instead

Codex CLI has no --header flag, so X-API-Key goes in ~/.codex/config.toml. For Cursor and Claude Code, swap the header.

[mcp_servers.hookmyapp]
url = "https://api.hookmyapp.com/mcp"
env_http_headers = { "X-API-Key" = "HOOKMYAPP_API_KEY" }

claude mcp add --transport http hookmyapp https://api.hookmyapp.com/mcp \
  --header "X-API-Key: $HOOKMYAPP_API_KEY"

{
  "mcpServers": {
    "hookmyapp": {
      "url": "https://api.hookmyapp.com/mcp",
      "headers": {
        "X-API-Key": "${env:HOOKMYAPP_API_KEY}"
      }
    }
  }
}

Examples

Ask your agent to check setup:

Use HookMyApp MCP to check my organization status and tell me the next action.

Ask your agent to inspect channels:

Use HookMyApp MCP to list my workspaces, then list the WhatsApp channels in the active workspace.

Ask your agent to send a message:

Use HookMyApp MCP to send "Hello from HookMyApp" from channel ch_xxxxxxxx.

Project MCP vs docs MCP

Server	Endpoint	Use it for
Project MCP	`https://api.hookmyapp.com/mcp`	Operating HookMyApp with the CLI-configured credential or an API key
Docs MCP	Not published yet	Documentation lookup only

Use the CLI when your agent has terminal access. Use MCP when your agent supports MCP and should operate HookMyApp directly.
