This server offers a convenient integration for wacrm users with AI assistants, but attention to permissions and risk control is needed.

Why each score
Reliability 3/20
A well-formed manifest is provided and describes a plausible stdio npm server, but no server source, tests, or CI workflow for the MCP server was supplied. There is no verifiable evidence that the init and tool-list handshake succeeds, or that declared tools match real behavior. The score is downgraded for missing executable evidence and committed tests; the static calibration cap is 12, and the evidence is well below that.
Security and permissions 10/20
No red-line issues were found. The API key is marked as secret, writes are disabled unless WACRM_ENABLE_WRITES=true, and broadcasts additionally require WACRM_ENABLE_BROADCASTS, which is a good least-privilege default. Deductions: there is no source to verify that tools actually enforce API key scopes, no confirmation flow for write/broadcast operations is documented, and there is no data-flow disclosure for external WhatsApp calls. This fits the 10-point band where main risks are visible but permissions/confirmation/scoping are incomplete.
Maintenance 8/20
The repository is not archived, has an MIT license, and the package version is 0.1.1. No release history, commit cadence, dependency-update evidence, or security-response channel was supplied; stars are treated as discovery signals only and add no points. The score is deducted for missing governance and versioning evidence.
Documentation 8/20
The README gives a product overview and points to docs/mcp.md and public API docs, and the manifest explains the environment variables. However, no MCP-specific documentation was supplied: no tool parameter reference, no scopes/limits, no cost guidance, and no troubleshooting section. The score is deducted for missing tool-level and troubleshooting documentation.
Setup experience 7/20
The npm identifier, stdio transport, and required environment variables are clearly declared, which gives a plausible setup path. But no MCP client configuration examples for Claude/Cursor, no prerequisites list, and no installation verification were included. The setup is plausible but unverified; the static calibration cap is 15, and missing execution evidence lowers the score to 7.

Fit and risk

What it can accessUses the networkChanges third-party account data

Best for

  • Teams or individuals using wacrm who want to increase CRM productivity via AI assistants
  • Developers who need self-hosting with full control over data and configuration

Not for

  • Users not using wacrm or WhatsApp Business API
  • Those requiring an official, upstream-maintained MCP server (this is community-maintained)

Required permissions

  • Requires an API key from the wacrm instance; scopes define allowed actions
  • Read-only by default; enabling WACRM_ENABLE_WRITES allows contact create/update and message sending
  • Enabling WACRM_ENABLE_BROADCASTS allows mass broadcasts

Risks and side effects

  • API key leakage could lead to unauthorized access or actions
  • With writes/broadcasts enabled, AI might execute unintended operations
  • Misconfiguration of the self-hosted instance may cause connection failures

Setup

Before you start

Runtime：Node.js

WACRM_BASE_URL required Base URL of your self-hosted wacrm instance, e.g. https://crm.example.com.
WACRM_API_KEY requiredsecret API key generated in the CRM under Settings → API keys; its scopes decide what is allowed.
Other optional settings (2)
WACRM_ENABLE_WRITES optional Set to true to expose contact create/update and message sending; read-only when unset.
WACRM_ENABLE_BROADCASTS optional Set to true to expose the mass-broadcast tool; requires WACRM_ENABLE_WRITES.

Install the wacrm-mcp npm package and configure environment variables: WACRM_BASE_URL (base URL of your wacrm instance), WACRM_API_KEY (API key from Settings), WACRM_ENABLE_WRITES (set to true to enable writes), WACRM_ENABLE_BROADCASTS (set to true to enable broadcasts, requires writes).

Check that it works

Confirm wacrm tools appear in your MCP client's tool list, then ask a read-only question such as listing contacts — returning real data from your wacrm instance proves the connection works.

Troubleshooting

  1. Check that WACRM_BASE_URL is reachable from the MCP client
  2. Verify the API key is valid and has required scopes
  3. Ensure environment variables are set correctly, especially WACRM_ENABLE_WRITES when enabling writes

Things to try

Once connected, you can ask your AI assistant things like:

  • List all contacts in my wacrm CRM
  • Show the most recent open conversations and who they are assigned to
  • Tag the customer John as vip
  • Send a WhatsApp reply to the customer's latest message

Use cases

View contacts, conversations, and pipeline data from AI assistants
AI-drafted replies (with writes enabled)
Run no-code automations or broadcasts (with appropriate permissions)

Supported clients

Claude Desktop
Cursor

Overview

This MCP server allows AI assistants like Claude and Cursor to interact with a self-hosted wacrm instance, a CRM template for WhatsApp providing shared inbox, contacts, sales pipelines, broadcasts, and no-code automations. It is read-only by default, with optional write and broadcast features.
