MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
作者提供的说明(英文原文)
Hosted MCP server for Anvil — fill & generate PDFs and run Etch e-signature packets for AI agents.
这三项永远不会合并成一个分数:意见、测量和人气是不同的东西。
我们还没有为它写通俗的介绍。下面是我们从注册中心读取到的事实。
选择你使用的 AI 应用,然后复制设置。

你用的是哪个应用?
在上方选择你的应用。我们会记住它,下次按钮会显示“安装到 …”。
适用于网页版、桌面版和手机版 Claude:
https://anvil.usefulapi.io/mcp在终端中运行这条命令
claude mcp add --transport http anvil https://anvil.usefulapi.io/mcp粘贴到项目中的 .cursor/mcp.json,或 ~/.cursor/mcp.json
{
"mcpServers": {
"anvil": {
"url": "https://anvil.usefulapi.io/mcp"
}
}
}浏览器会先询问是否打开应用,然后应用会显示设置并请你确认。密钥的值会留空,由你自己填写。
粘贴到项目中的 .vscode/mcp.json

工具名称和描述与服务器在 2026年11月6日 报告的完全一致。这些内容由作者撰写,不是我们写的;我们以纯文本形式显示。
anvil_current_userGet the authenticated Anvil user (from the API key) and the organizations they belong to (eid, name, slug). Good first call to discover org slugs/eids for other tools. GraphQL query: currentUser.
anvil_get_organizationFetch an Anvil organization and its PDF templates (casts) and workflows (welds). Provide either its slug or its eid (at least one is required). GraphQL query: organization.
anvil_get_castFetch a cast — an Anvil PDF template — by its eid: title, version number, and whether it is a template. Use the returned eid as the cast_eid for anvil_fill_pdf. GraphQL query: cast.
anvil_get_etch_packetFetch an Etch e-signature packet by eid: its status, details URL, document group, and every signer (eid, aliasId, name, email, status, routing order). Use this to check signature progress. GraphQL query: etchPacket.
anvil_get_weldFetch a weld — an Anvil workflow — by eid, including its forges (the individual form steps: eid, name, slug). GraphQL query: weld.
anvil_get_weld_dataFetch a weldData record — a single submission to a weld (workflow) — by eid: completion state, test flag, and creation time. GraphQL query: weldData.
anvil_fill_pdfFill an Anvil PDF template (cast) with data and return the finished PDF as base64. REST: POST /fill/{castEid}.pdf. Returns { filename, byteLength, pdfBase64 }. The `data` object's keys are the template's field aliases.
anvil_generate_pdfGenerate a brand-new PDF from HTML or Markdown and return it as base64. REST: POST /generate-pdf. For type=html, pass data = { html, css? }. For type=markdown, pass data = [ { label, content }, ... ]. Returns { filename, byteLength, pdfBase64 }.
anvil_create_etch_packetCreate an Etch e-signature packet (documents + signers). GraphQL mutation: createEtchPacket. IMPORTANT: isDraft defaults to true (a safe draft that sends nothing). Setting isDraft=false with real signers SENDS signature-request emails to those signers. Use isTest=true while devel
anvil_generate_etch_sign_urlGenerate a one-time embedded signing URL for a specific signer in an Etch packet (for iframe/redirect signing flows). GraphQL mutation: generateEtchSignURL. Returns { url }.

与注册中心里这个分类中所有活跃的服务器比较。只有当发布者拥有该仓库时,星标数才计入。
它在 3 项适用的基础检查中通过了 3 项。我们没有阅读代码。在添加密钥或令牌之前,请先看看这个服务器要求哪些权限,并使用只具备所需权限的密钥。
注册中心没有列出必需的密钥,不过有些服务器会在首次使用时要求你登录。
它在作者的云端运行。通过互联网连接,无需安装,但你发送的内容会经过作者的服务器。
GitHub 仓库最后更新于–,最新版本(1.35.3)于昨天进入注册中心。
支持 MCP 的应用,例如 Claude Desktop、Claude Code、Cursor 和 VS Code。它通过 URL 连接,所以接受远程 MCP 服务器的应用也可以使用,例如开启开发者模式的 ChatGPT。

Fill and generate PDFs and run Etch e-signature packets from Claude, Cursor, or any MCP client. Hosted, no local install — connect with your Anvil API key.
Live endpoint: https://anvil.usefulapi.io/mcp · Homepage: https://usefulapi.io/anvil
https://anvil.usefulapi.io/mcp.claude mcp add --transport http anvil https://anvil.usefulapi.io/mcp, then run /mcp to log in.{
"mcpServers": { "anvil": { "url": "https://anvil.usefulapi.io/mcp" } } }
Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Anvil credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/anvil/
On first connect you'll paste your Anvil API key. It's validated, stored per-user, and scoped to you.

| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Pro | $9/mo or $90/yr (2 months free) | Unlimited* |
\*Pro has a fair use limit of 10,000 tool calls a month on this server. For more, write to support@usefulapi.io.
Pro covers this server only. Subscribe with anvil_upgrade (it returns a Stripe Checkout link). Cancel any time with anvil_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running anvil_upgrade before then undoes the cancel.
