What the code does

We read the source, 17 h ago · rules 995398eba69f

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Builds a database query by concatenation ee/messaging/activities/record-activity-query.ts:274, content/blog-posts/en/excel-crm-template.mdx:72

      SELECT 1 FROM "CrmRecord" record WHERE record."companyId" = ${companyId} AND record."typeId" = historical."typeId" AND record.id = historical.id AND record."deletedAt" IS NULL

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.

Customermates — questions

Answers built from our own checks of this server.

Why is there no tool list for Customermates?

The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 98.9% of checks in the last 24 hours got a reply.

Is Customermates working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 92 checks got a reply (98.9%), average response time 256 ms. The bar chart above shows every period we have measured.

How do I connect Customermates?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.

How do you sign in to Customermates?

No API key is involved. Customermates answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.

How fast is Customermates?

It answers our handshake in 256 ms on average, which is faster than 53% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Customermates open source?

The code is open source: it is published under the AGPL-3.0 licence, written in TypeScript and 219 stars on GitHub. The licence covers the code in the repository, not the hosted service at customermates.com, which runs on its operator's own terms.
