_{▶ Watch the 30-second demo - demo data is simulated; every command shown exists in the real CLI.}

Every Sherweb Partner API capability, plus a local SQLite store, offline analytics, and margin/drift/orphan joins no other Sherweb tool has. Works with the AI you already use - ChatGPT (desktop app), Claude Desktop, Codex, Claude Code, Claude Cowork, and GitHub Copilot - plus Gemini CLI. Free, open source, runs on your laptop. Built for MSP owners. No code required.

Works with your agent

Security note (until this connector is reprinted). Do not run HTTP mode (--transport http), not even on localhost. This build has no password, listens on every network interface, and predates the browser-rebinding guard, so a web page you open can reach it. The MCP tools can also make changes with your credentials. Use the default stdio transport. If you set up a tunnel for a remote agent, shut it down. A fix is on the way.

The six agents MSP owners actually use (self-serve, works today):

The ChatGPT desktop app runs sherweb-mcp locally and shares MCP configuration with Codex (OpenAI). ChatGPT on the web needs a remote (HTTP) server, and this connector's HTTP mode is paused until it is reprinted (see the security note in mcp-install.md), so msp-skills does not support it yet. If your team works there, a hosted gateway is the better pick; check that your AI app is on the gateway's setup list.

Also for the Microsoft and Google stacks

Big install base, but an honest heads-up: Gemini CLI runs the local binary you just installed, while Microsoft 365 Copilot and the Gemini app need a remote server, which msp-skills does not support yet.

Skill-native agents (also covered): Hermes and OpenClaw read this skill's SKILL.md directly and speak MCP - see their install sections below. Also works with Cursor, Windsurf, Cline, Continue.dev, and Zed via MCP. Full per-tool wire-up: docs/which-agent.md.

Run more than one agent? Install across all 51+ supported agents in one command: npx skills add Servosity/msp-skills@latest (requires Node.js, then run the per-skill installer for the CLI/MCP binaries). See docs/which-agent.md.

Install in 60 seconds

Fastest for Claude Desktop - one-click .mcpb

Claude Desktop bundle: the .mcpb launches on macOS (Intel and Apple Silicon), Windows x64 and Linux x64. Every tool shells out to the companion sherweb-cli. Releases cut from 2026-09-18 on ship that CLI inside the bundle; older bundles contain only the MCP server, so if yours lacks the companion, run the Path A or Path B installer below first (or set SHERWEB_CLI_PATH to an existing binary). Details: #331.

Download Sherweb MCP (.mcpb) - then open Claude Desktop > Settings > Extensions and select the file. One click, no JSON, no shell. (Browse every Sherweb release on the releases page.)

Prefer the Claude Code plugin? Add the marketplace once, then install - works immediately, no directory listing required:

/plugin marketplace add Servosity/msp-skills/plugin install sherweb@msp-skills

Path A - paste one prompt into your AI agent (recommended)

Copy this into Claude Code, Codex CLI, or Claude Cowork:

Install the Sherweb Skill and MCP server from Servosity/msp-skills in this agent workspace. If this workspace uses a POSIX shell (macOS, Linux, WSL, or Bash), run bash <(curl -fsSL https://raw.githubusercontent.com/Servosity/msp-skills/main/skills/sherweb/install.sh). If it uses Windows PowerShell, run iwr -useb https://raw.githubusercontent.com/Servosity/msp-skills/main/skills/sherweb/install.ps1 | iex. Then authenticate per the README and run sherweb-cli --help to explore.

The same prompt works in any agent that can run shell.

Path B - run the installer yourself

Windows (PowerShell):

iwr -useb https://raw.githubusercontent.com/Servosity/msp-skills/main/skills/sherweb/install.ps1 | iex

macOS / Linux:

bash <(curl -fsSL https://raw.githubusercontent.com/Servosity/msp-skills/main/skills/sherweb/install.sh)

The installer drops both sherweb-cli (the CLI) and sherweb-mcp (the MCP server) into your user bin path. Claude Code, Codex, and Cowork discover the Skill via SKILL.md in this directory.

Verify:

sherweb-cli --version

Upgrade to the latest version

The installer always fetches the current release - re-run it to upgrade:

macOS / Linux:

bash <(curl -fsSL https://raw.githubusercontent.com/Servosity/msp-skills/main/skills/sherweb/install.sh)

Windows (PowerShell):

iwr -useb https://raw.githubusercontent.com/Servosity/msp-skills/main/skills/sherweb/install.ps1 | iex

Claude Desktop .mcpb users: download the latest .mcpb (top of this section) and re-select it in Settings > Extensions. Claude Code plugin users: /plugin update sherweb@msp-skills.

Add to Claude Desktop, the ChatGPT desktop app, GitHub Copilot, Gemini CLI, or another MCP client

After the installer runs, see mcp-install.md and docs/which-agent.md for the per-agent wire-up - one section per agent, including the GitHub Copilot servers key and the ChatGPT desktop app. Claude Desktop's Settings > Extensions panel is the simplest path; the MCP config block (for users who prefer editing JSON) is documented in mcp-install.md.

Install for Hermes

From the Hermes CLI:

hermes skills install servosity/msp-skills/skills/sherweb --force

Inside a Hermes chat session:

/skills install servosity/msp-skills/skills/sherweb --force

Hermes speaks MCP natively, so it can also use the sherweb-mcp server directly - same install path, same env vars.

Install for OpenClaw

Tell your OpenClaw agent (copy this):

Install the sherweb skill from https://github.com/servosity/msp-skills/tree/main/skills/sherweb. The skill defines how its required CLI (sherweb-cli) can be installed via the openclaw: frontmatter block.

OpenClaw isn't generally available yet; the frontmatter wiring is pre-shipped and will activate the moment OpenClaw launches.

Authenticate

Set the credentials the CLI needs (from your Sherweb portal):

SHERWEB_CLIENT_ID=<value> SHERWEB_CLIENT_SECRET=<value> SHERWEB_OAUTH_SCOPE=<value> SHERWEB_SUBSCRIPTION_KEY=<value> sherweb-cli doctor

doctor confirms the credentials work before you run anything that touches data. It exits 0 even when the credential is rejected, so scripts should add --fail-on error.

What makes this different

Most Sherweb integrations and MCP servers proxy each question into a live API call. That's fine for one record. It dies at scale, when you're asking "what's my net margin across all 80 customers this month" and the answer means stitching the Distributor billing endpoints to per-customer receivable charges, subscriptions, and usage one client at a time.

This skill syncs Sherweb into a local SQLite mirror with full-text search. Aggregate questions become one local SQL join: instant, offline, and the AI sees the answer, not the raw data. Compound commands like margin, orphans, and usage-leak join across payable charges, receivable charges, subscriptions, and metered usage - work a stateless API wrapper can't do.

The pain this closes

The Sherweb Partner API splits billing across two surfaces: the Distributor API returns the payable charges (what you owe Sherweb) and the Service Provider API returns the receivable charges and subscriptions (what you bill clients). No portal screen joins them, so net margin per customer gets rebuilt by hand in a spreadsheet every close. The recurring r/msp version is "license sprawl" - a client downsizes, the subscription stays active on the Sherweb side, and you keep paying for seats you never bill back. This skill closes that gap from your synced mirror:

• sherweb-cli margin - net margin per customer (receivable minus payable), worst-margin-first.
• sherweb-cli orphans - active subscriptions with zero receivable charges: seats you pay for but never bill.
• sherweb-cli usage-leak - metered usage with no matching receivable charge: consumption you absorb.
• sherweb-cli right-size - subscriptions where paid seats differ from metered seats used.
• sherweb-cli margin-trend --last 6 - each customer's margin across recent closes, steepest-decline-first.

See pain-point.md for the longer narrative.

Frequently asked questions

Does this work with ChatGPT?

Yes, in the ChatGPT desktop app. It runs MCP servers locally (STDIO), the way sherweb-mcp runs, and shares MCP configuration with Codex (OpenAI): add sherweb-mcp under Settings > MCP servers as a STDIO server, or add it once to Codex's ~/.codex/config.toml. ChatGPT on the web is not supported by msp-skills yet: it needs a remote (HTTP) server, and this connector's HTTP mode is paused until it is reprinted; the security note in mcp-install.md explains why. If your team works there, a hosted gateway is the better pick; check that your AI app is on the gateway's setup list.

Does this work with Codex, Cursor, Windsurf, Cline, Copilot, or Gemini?

Yes - all of them speak MCP. Cross-tool install commands are in the matrix above and the deep-dive in docs/which-agent.md.

Do I need to know how to code?

No. The recommended install is to paste one sentence into Claude Code or Codex - your agent reads SKILL.md and does the install. The fallback is a one-line installer per OS (bash or PowerShell). Neither path requires writing code. You'll enter your Sherweb credentials once.

Is my Sherweb data safe?

Your data stays on your machine. The CLI and MCP server are local binaries. The SQLite mirror sits in a directory under your user account. The AI agent only sees what the CLI returns - typically a query result, not raw bulk data. Credentials are read from your environment or your agent's config; never bundled into this repo or transmitted anywhere by MSP Skills.

Do I need to be a Sherweb partner, and what credentials does it use?

Yes - it talks to the Sherweb Partner API with your own partner credentials, using composed authentication. You need an OAuth2 client-credentials Client ID and Secret (with a scope) for the bearer token, plus an APIM gateway subscription key that rides on every call. Create the OAuth2 application and copy the subscription key from cumulus.sherweb.com under Security > APIs, then set SHERWEB_CLIENT_ID, SHERWEB_CLIENT_SECRET, SHERWEB_OAUTH_SCOPE, and SHERWEB_SUBSCRIPTION_KEY. The credential's own permissions are the real boundary - scope it to what you want the AI to reach.

Will this hit my Sherweb API rate limits?

After deep-sync, the analytics commands (margin, margin-trend, orphans, usage-leak, right-size, drift, sub-changes, fleet-subs, amend-preview) run against your local SQLite mirror with zero API calls. Live calls respect a --rate-limit throttle, and sync is resumable and incremental - it only fetches what changed since the last checkpoint.

Does this replace the Sherweb portal?

No. Provisioning, ordering, and subscription management stay in the portal. This skill answers the cross-entity margin and billing questions the portal cannot compose in one place - net margin, orphaned subscriptions, usage leakage, seat right-sizing - from your terminal or agent.

What does it cost?

Free. Apache-2.0 licensed. You pay only for whichever AI agent you use (Claude, ChatGPT, Codex, etc.), and that's billed by your AI provider, not by us.

Safety model

The strongest control is the scope you grant the Sherweb credentials - the CLI can only do what the credentials are permitted to do. Full details, including how to lock it down, are in governance.md.

Status

Beta. Validated against the Sherweb API surface and being validated with MSPs running it live against their own production tenant in our weekly Build Sessions. RSVP at compoundingteams.com/build-sessions.

Standards. Conforms to the open Agent Skills spec (Anthropic, Dec 2025; 40+ agents). MCP-compatible - works with any MCP-capable agent including Hermes. OpenClaw-ready (frontmatter pre-wired, awaiting OpenClaw launch).
