Easyhook MCP Server

Use Easyhook from Codex, Claude, and other Model Context Protocol clients. The server fixes one Easyhook sender and only permits reading from or writing to contacts explicitly listed at startup.

Security model

• EASYHOOK_API_KEY is read from the MCP process environment and is never accepted as a tool argument.
• EASYHOOK_FROM fixes the sender for every operation.
• EASYHOOK_ALLOWED_TO is a required comma-separated allowlist. Every send and message read is checked locally.
• There is no unrestricted HTTP tool and no tenant administration tool.
• Keep the API key outside prompts, repositories, and workflow inputs.

Install in Codex

codex mcp add easyhook \
  --env EASYHOOK_API_KEY=eh_live_xxx \
  --env EASYHOOK_FROM=5218661479075 \
  --env EASYHOOK_ALLOWED_TO=5215660069997,528442461514 \
  -- npx -y easyhook-mcp-server

Equivalent ~/.codex/config.toml:

[mcp_servers.easyhook]
command = "npx"
args = ["-y", "easyhook-mcp-server"]

[mcp_servers.easyhook.env]
EASYHOOK_API_KEY = "eh_live_xxx"
EASYHOOK_FROM = "5218661479075"
EASYHOOK_ALLOWED_TO = "5215660069997,528442461514"

Restart the MCP client after changing configuration.

Optional configuration

Variable	Required	Description
EASYHOOK_API_KEY	Yes	Easyhook organization API key.
EASYHOOK_FROM	Yes	Fixed Easyhook WhatsApp sender. Formatted numbers are normalized to digits.
EASYHOOK_ALLOWED_TO	Yes	Comma-separated readable and writable contact phone allowlist.
EASYHOOK_BASE_URL	No	API origin. Defaults to https://api.easyhook.dev.

Tools

Tool	Purpose
send_text	Send standard, scheduled, or humanized text.
send_media	Send media by reusable name, Meta id, or public URL.
send_template	Send an approved WhatsApp template.
send_flow	Send a published WhatsApp Flow.
send_consent_flow	Send the default opt-in or opt-out Flow.
list_templates	List templates for the configured sender's WABA.
list_media	List reusable media for the configured sender's WABA.
list_flows	List Flows for the configured sender's WABA.
list_conversations	List recent conversations, filtered to allowlisted contacts.
get_recent_messages	Read inbound and outbound messages with one allowlisted contact.

Conversation tools always use EASYHOOK_FROM. get_recent_messages rejects contacts outside EASYHOOK_ALLOWED_TO; list_conversations removes non-allowlisted contacts before returning data to the MCP client.

Easyhook service-window, consent, wallet, template, and Meta policy checks still apply.
