@m00nsolutions/mcp-server

Agentic test management over MCP. This server lets an AI assistant do the work rather than read about it: author test cases, plan and populate manual test executions, link automation back to the cases it covers, cut releases and read project health in M00N Report, an AI-native test management platform.

Which Install Do I Need?

	This npm package (stdio)	Hosted remote connector
How it runs	`npx @m00nsolutions/mcp-server` as a local process	No local process; the client talks to the API over HTTP
Auth	An MCP key in `M00N_API_KEY`	OAuth 2.1 with PKCE, browser consent screen
Clients	Any MCP client: Claude Code, Claude Desktop, Cursor, and others	claude.ai and claude.com only

If you are not connecting from claude.ai or claude.com, use this package with an MCP key. That is the rest of this README. For the connector, see the connector guide.

Requirements

Node 20 or newer, and any MCP-capable client.

Installation

No install step. The client launches it with npx, as configured below.

To pin a version in a shared or CI environment, append one to the package name in args, like ["-y", "@m00nsolutions/mcp-server@<version>"]. npm view @m00nsolutions/mcp-server versions lists what is published. A placeholder rather than a number on purpose: a concrete example here goes stale on the next release, and a stale one recommends pinning to a version that no longer has the current fixes.

Quick Start

1. Get an MCP key

In M00N Report, open Settings -> MCP Keys and create a key. It starts with m00n_mcp_ followed by 48 hex characters. This is not the credential the test reporters use; theirs starts with m00n_ and is refused here.

An MCP key carries exactly the permissions of the account it belongs to, never more, and can be scoped down further. Scoping removes tools from the list the client sees, so a shorter tool list than you expected is a scoping decision, not a fault.

The key goes in your own MCP client config on your machine. Do not put it in a workspace file that lives in a repository.

2. Connect your client

Claude Code, one line:

Terminal

claude mcp add m00n --env M00N_API_URL=https://m00nreport.com --env M00N_API_KEY=m00n_mcp_... -- npx -y @m00nsolutions/mcp-server

Every other client takes the same JSON block:

config.json

{
  "mcpServers": {
    "m00n": {
      "command": "npx",
      "args": ["-y", "@m00nsolutions/mcp-server"],
      "env": {
        "M00N_API_URL": "https://m00nreport.com",
        "M00N_API_KEY": "m00n_mcp_your_key_here"
      }
    }
  }
}

Where that block goes:

Client	Config file
Cursor	`~/.cursor/mcp.json`
Claude Desktop, macOS	`~/Library/Application Support/Claude/claude_desktop_config.json`
Claude Desktop, Windows	`%APPDATA%\Claude\claude_desktop_config.json`

For a self-hosted instance, point M00N_API_URL at your own root origin, with no /api suffix. A trailing slash is stripped for you.

3. Confirm the connection

Restart the client, then ask it:

List my M00N Report projects

A list of your projects means the server is connected and the key is valid. An error, or the assistant saying it has no such tool, means it is not; see Troubleshooting.

Tools

Eight areas. The full list with arguments is at /documentation/mcp/tools, kept beside the code. The server fetches its own list from your instance at startup, so what your client sees is what your instance supported when the client connected.

Area	What it covers
Projects and analytics	Projects, launch trends and statistics, per-test history, search across automated tests
Test cases	Create, read, update, move, delete, bulk edit, and link an automated test to the case it covers
Folders and suites	The folder and suite hierarchy, plus per-folder statistics
Test collections	Reusable named case sets that drop into any execution
Manual executions	Build an execution from suites, collections or individual cases, then record per-case results
Releases	Create and manage releases, and attach or detach the launches that belong to them
Health and coverage	A composite health check, coverage gaps in both directions, case suggestions, feature scan, report export
External links	Attach and remove Jira or Linear tickets on a case

An execution is a manual test run: assignees, environment, dates, and per-step results captured against a snapshot of each case at the moment it was added.

How many tools your key can see comes from your instance:

Terminal

curl -s -H "X-MCP-Key: $M00N_API_KEY" "$M00N_API_URL/api/mcp/tools" | jq .count

A scoped key sees fewer. No number is quoted here on purpose: the surface changes with the release, and a figure in a README is the one place nobody remembers to update.

Prompts

Guided multi-step workflows the client can offer by name. Each takes a single optional project argument, a name or a UUID; omit it and the server picks the project when only one is in scope.

Prompt	What it does
`analyze_flaky_tests`	Find tests that pass and fail without a code change, and rank them
`debug_test_failure`	Work a single failure back to a cause from its history and traces
`release_readiness`	Judge whether a release is safe to ship
`generate_test_cases`	Draft manual cases for an area that has none
`weekly_health_report`	Summarise the week across projects
`investigate_regression`	Find what changed between a passing and a failing run
`run_manual_execution`	Take a manual test cycle from assembly to per-case results

Resources

Read-only views the client can pull without calling a tool: all projects, project health summary, flaky tests report, currently failing tests, folder structure, launch report, test case content, release summary.

Configuration

Env var	Required	Default	Description
`M00N_API_URL`	to connect		Your M00N Report URL. Root origin, no `/api` suffix. A trailing slash is stripped for you.
`M00N_API_KEY`	to connect		An MCP key (`m00n_mcp_...`). Anything without that prefix is refused before the first request.
`M00N_DEBUG`	no	`false`	Adds per-request detail to stderr, including each tool call's arguments. Startup steps and errors are logged either way.
`M00N_TIMEOUT_MS`	no	`30000`	Request timeout, a bare number of milliseconds. `60s`, `1e4`, `30,000` and `1.5` are rejected with a warning on stderr and the default is used instead.
`M00N_INSECURE_SSL`	no	`false`	Accept a self-signed certificate. Self-hosted instances only.

The two booleans are on for true, 1 or yes, in any case. Every other value, false and 0 included, leaves them off.

Set both of the first two or neither. Setting one is treated as a mistake and refused, because a half-configured server that starts anyway is harder to diagnose than one that does not.

The base URL is M00N_API_URL here; the test reporters call the same URL M00N_SERVER_URL. All six packages read M00N_API_KEY, but theirs is a project API key rather than an MCP key, so one exported shell variable cannot serve both.

Running Without a Key

Started with neither M00N_API_URL nor M00N_API_KEY, the server runs in preview mode: it lists its tools, prompts and resources from a bundled snapshot and refuses every call with a message saying what to set. Nothing is sent anywhere, because there is nowhere to send it.

That is what lets an inspector, a client or a directory show the tool surface before anyone has signed up. It is a description of the server, never a working one, so the listings come from the snapshot rather than from your instance: a scoped key normally sees fewer tools than the snapshot shows.

Maintainers refresh the snapshot with npm run snapshot:refresh against an unscoped key.

Self-Hosted

Point M00N_API_URL at your own instance and issue the MCP key from that instance. Everything else is identical, which matters when the reason you self-host is that test data cannot leave your network.

With a self-signed certificate, add "M00N_INSECURE_SSL": "true" to the same env block. Full notes: /documentation/mcp/self-hosted.

What Gets Sent

To M00N_API_URL over HTTPS: the tool calls your assistant makes and their arguments. The server is a proxy to your own instance and stores nothing itself.

Every tool call is written to an MCP audit log with a UI in the app, and per-key rate limiting caps a runaway agent. The key is never written to that log, nor to stderr. Under M00N_DEBUG the arguments of every tool call are printed to stderr, so treat that output as you would the data itself.

Troubleshooting

Symptom	Cause
The client shows no M00N Report tools	The config was not reloaded. Restart the client fully, not just the conversation.
Tools are listed but every call answers `running unconfigured`	Neither `M00N_API_URL` nor `M00N_API_KEY` reached the process, so it started in preview mode. Check the `env` block actually applies to this server.
`M00N_API_KEY should start with "m00n_mcp_"`	That is a project API key, the kind the test reporters use. MCP keys are separate: Settings -> MCP Keys.
`Authentication failed: Invalid or expired MCP key`	The key is wrong, revoked, or from another instance. Or `M00N_API_URL` carries an `/api` suffix, which makes every request 401 however good the key is. Check the URL first, then issue a new key.
`WARNING: M00N_API_URL is http://...`	Not an error, and the server keeps running. It means the key is sent unencrypted on every request. Use `https` unless the instance is on a trusted private network. Loopback addresses do not warn.
`... redirected to ...`	The URL answers with a redirect, and redirects are not followed because the MCP key would travel to wherever they point. Set `M00N_API_URL` to the address that answers directly, usually the `https://` form.
`Cannot connect to M00N Report API at ...`	Nothing is listening at that URL. The instance is down, or the port is closed to you.
`Cannot resolve M00N Report API host`	The hostname does not resolve. A typo, or a private name reached from outside its network.
`Request to M00N Report API timed out`	Raise `M00N_TIMEOUT_MS`, or check the network path.
`SSL certificate error connecting to ...`	A self-signed certificate on a self-hosted instance. Set `M00N_INSECURE_SSL` to `true`.
`Not found during ...`	The rest of the line is the server's own answer and usually names the fix, such as which projects do exist. Read it before changing a setting.
`Rate limit exceeded. Retry after Ns.`	1000 tool calls per minute per key, on a sliding window. The message carries the wait. An agent working a task rarely comes close; hitting this usually means a loop.
Fewer tools than expected	The key is permission-scoped, or the instance is older than the package. The tool list comes from your instance.

The server logs to stderr with or without M00N_DEBUG, and most clients surface it in their MCP panel. Set M00N_DEBUG to true to add each request and its arguments.

Known Limitations

The tool list is read once, at startup. Re-scope a key or upgrade the instance and the client keeps the old list until you restart the client.
GET /api/health must be reachable when configured. It is checked before anything else and a failure stops the server, so a proxy forwarding only /api/mcp/* shows no tools at all even though every tool would work.
A key scoped to zero tools does not start. The server exits rather than connecting with an empty list. This is the configured path; with no credentials at all it starts in preview mode instead.
Prompts and resources are optional. If their listings fail, the server still starts, with the reason on stderr, and the client sees none of them for the whole session.
Redirects are refused, not followed. The key rides in a custom header, and redirect followers strip only the auth headers they recognise, so following one would hand the key to whatever host answered next. A redirect is reported with the address it pointed at.
stdio only. For an HTTP transport, use the hosted connector.
