SpendSignoff is now an official Claude Code plugin
Starting today, SpendSignoff appears in the Claude Code plugin registry. You can install it with a single command instead of editing JSON config. The underlying MCP server, the safety scopes, and the approval gate are identical — the change is discovery and installation, not the product.
What "official plugin" means in practice
Anthropic's plugin registry is a curated list of MCP servers that Claude Code can install and configure automatically. Being listed means SpendSignoff passed Anthropic's review of the OAuth implementation, tool schema declarations, and safety scope documentation.
The practical difference for users: instead of opening ~/.claude/settings.json and typing the endpoint URL manually, you run one command:
Install via Claude Code
/install spendsignoffManual config still works
settings.json method, nothing breaks. The plugin install is an alternative path, not a replacement.What did not change
- Safety contract unchanged — the model holds
mcp.readandmcp.draftonly.mcp.approvedoes not exist and was never issued. - Approval gate unchanged — every proposed change still requires a two-step human confirm in the dashboard before it touches an account.
- Pricing unchanged — the free tier and paid tiers are the same. The plugin listing does not add a fee.
- Token vault unchanged — OAuth tokens are KMS-encrypted at rest; Claude Code never receives raw credentials.
Why this matters for adoption
The number one friction point in early SpendSignoff signups was the manual JSON config step. Most people setting up a new MCP server for the first time had never touched settings.json, and a typo meant a silent failure with no clear error message.
The plugin registry removes that step entirely. You get a working connection in thirty seconds instead of five minutes, with no config file to debug.
What comes next
The Claude Code plugin listing is V1 of the distribution work. We are in review for the ChatGPT plugin store as well. LinkedIn and TikTok ad platform support are on the near-term roadmap, and both will appear in the SpendSignoff plugin automatically once they ship — no reinstall required.
FAQ
- Do I need to reinstall SpendSignoff to get the plugin version?
- No. If you already use SpendSignoff via manual config, your setup continues to work. The plugin is a convenience path for new installs.
- Did Anthropic review the safety model as part of the listing process?
- Yes. The review covered the OAuth implementation, the scope declarations (
mcp.readandmcp.draftonly, nomcp.approve), and the tool schema definitions. The listing requires that safety documentation to be accurate and verifiable.
