A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.
- Delete the imperative ("run this", "execute the following") from inside the fence.
- If you must show setup, label the block

Why this exists
Airtable's public Web API has never exposed some of the most common tasks builders actually need: creating a formula field, tweaking a view's filter set, installing an extension, or validating a formula before it breaks production. The official Airtable MCP server is a thin wrapper over that same REST API, so it inherits every one of those gaps.
`airtable-user-mcp` is an add-on to the official Airtable MCP, not a replacement. It uses Airtable's own internal API (the one the web UI uses) to cover exactly the surface area the REST API can't reach. Register both servers in your AI client and your assistant gets the full Airtable automation experience — records over HTTP via the official MCP, plus schema, formulas, views, and extensions via this one.

What airtable-user-mcp adds on top of the official Airtable MCP
This is a coverage map, not a "pick one" decision — the two servers are complementary and designed to run side-by-side.

Use both MCPs together
npx -y airtable-user-mcp login # one-time browser login
claude mcp add airtable --scope user -- npx -y airtable-user-mcp # Claude Codeairtable-user-mcp is additive. Register the official Airtable MCP following Airtable's setup guide, then add this one alongside it in the same mcpServers block:
{
"mcpServers": {
"airtable-user-mcp": {
"command": "npx",
"args": ["-y", "airtable-user-mcp"]
}
}
}Your MCP client will expose every tool from both servers. The two entries are independent — rename the keys (airtable, airtable-official, airtable-user-mcp, etc.) however makes sense for your workflow.

Features
MCP Server (72 Tools + manage_tools)
Manage Airtable bases with capabilities not available through the official REST API:
| Category | Tools | Highlights |
|---|---|---|
| Schema Read | 11 | Full schema inspection — bases, tables, fields, views, sidebar sections, record templates; download all formula fields to local files |
| Record Read | 1 | query_records — up to 1 000 records/call with resolved field values; search param works on lookup/rollup fields (REST API filterByFormula doesn't) |
| Record Write | 4 | create_records / update_records / duplicate_records / upload_attachment (the only way to write multipleAttachments cells by URL) |
| Record Destructive | 1 | delete_records — batch-delete records from a table |
| Table Management | 3 | create / rename / delete tables |
| Field Management | 9 | Create formula / rollup / lookup / count fields, validate formulas, update descriptions, delete single or bulk |
| View Configuration | 20 | Filters, sorts, grouping, columns, freezing, row height, covers, color rules, calendar dates, create / duplicate / rename / delete |
| Sidebar Sections | 4 | Create, rename, move-into-section, delete (auto-promotes contained views to ungrouped) |
| Record Templates | 8 | Create / rename / describe / set cells / set columns / duplicate / apply / delete saved row scaffolds |
| Form Metadata | 2 | Description, redirect URL, attribution, copy-to-respondent, branding (legacy form views) |
| Extension Management | 7 | Create, install, enable/disable, rename, duplicate, remove extensions |
| Tool Management | 1 | List profiles, switch profile, toggle tools/categories (meta-tool, always enabled — not part of any profile) |
| Base Sync | 1 | sync_base — copy a base's schema, views, and records to another base. mode=plan/diff/status are read-only; mode=apply mutates the destination and, with policy=mirror plus the confirmation flags, can delete tables, fields, views, sections and records; mode=reconcile updates local mapping state. Drift-guarded and resumable via journal. |
| Daemon Control | 1 | manage_daemon — action=status is read-only self-diagnosis: daemon liveness, transport, uptime, tunnel URL, and the live session state (dead session, last breaker trip with Airtable's own response body, browser busy queue) that tells "daemon gone" from "session dead" from "browser busy". Also start / restart / stop / tunnel_enable / tunnel_disable / token_rotate. full profile only. |
See the full tool reference in packages/mcp-server/README.md.
#### One shared daemon
The extension starts the shared MCP daemon whenever a tool call needs one, so every VS Code window uses one Airtable browser session instead of one per window — that duplication is what produced most "session dead" errors. A daemon you stop from the dashboard stays stopped, and if it cannot start, the extension falls back to a per-window server so your tools keep working.
Because a daemon is usually running, other MCP clients on the same machine (Claude Desktop, Cursor, Cline, Amp) attach to it and therefore run under its auth mode and HTTP client rather than their own — deliberately, since two browsers on one Airtable profile crash. Each such client prints one stderr line saying so. See Sharing one daemon across clients.
LSP Server
`airtable-user-lsp` is a standalone language server for Airtable formula, script, and automation files — works in any LSP-capable editor, not just VS Code.
# stdio mode — works standalone, no daemon needed
npx airtable-user-lsp --stdioFeatures: diagnostics, completions, hover documentation, and signature help for .formula, .ats, and .ata files.
When the daemon is running, it auto-spawns airtable-user-lsp --tcp so multiple editors share one language server instance. The TCP port is written to ~/.airtable-user-mcp/daemon.lock as port_lsp.
See packages/lsp-server/README.md for per-editor configuration (Neovim, Zed, OpenCode, Helix).
Supported IDEs
The extension auto-configures MCP for all major AI-enabled editors:

Requirements
- VS Code ^1.100.0 (or any fork exposing the
McpServerDefinitionProviderAPI) - Node.js — bundled via the VS Code runtime; no separate install needed
- Google Chrome (or Edge / Chromium) — the Airtable login flow uses Patchright in headless mode. Falls back to
msedgeon Windows andchromiumon Linux. The extension shows an actionable warning if no supported browser is detected.
Development
This is a pnpm monorepo.
| Package | Description |
|---|---|
packages/extension | VS Code extension host (TypeScript + tsup) |
packages/webview | React dashboard webview (Vite + Tailwind v4) |
packages/shared | Shared types and message protocol |
packages/mcp-server | airtable-user-mcp — ESM Node MCP server |
packages/lsp-server | airtable-user-lsp — LSP server for formula / script / automation files |
scripts/ | Build tooling (esbuild bundler, dep vendoring) |
pnpm install # install all packages
pnpm build # build shared → webview → mcp bundle → extension
pnpm package # build + create airtable-formula-X.Y.Z.vsix
pnpm test # run all unit tests
pnpm dev # start webview dev server (browser preview)How the MCP server is bundled: scripts/bundle-mcp.mjs esbuilds packages/mcp-server/src/ into packages/extension/dist/mcp/. Then scripts/prepare-package-deps.mjs vendors patchright, patchright-core, otpauth, impit and @ngrok/ngrok into dist/node_modules/ before vsce package runs, so an installed extension needs no npm install at runtime.
Platform-specific VSIXes. impit (the Chrome-TLS HTTP client) and @ngrok/ngrok (the ngrok tunnel provider) keep their compiled native binary in separate per-platform npm packages, and only the one matching the build machine is ever installed. A single VSIX therefore cannot carry working native binaries for every platform. Instead we publish one VSIX per platform, each vendoring only its own binaries — VS Code and Open VSX hand each user the build matching their machine. Supported targets:
| Target | impit | @ngrok/ngrok |
|---|---|---|
win32-x64 | impit-win32-x64-msvc | @ngrok/ngrok-win32-x64-msvc |
win32-arm64 | impit-win32-arm64-msvc | @ngrok/ngrok-win32-arm64-msvc |
darwin-x64 | impit-darwin-x64 | @ngrok/ngrok-darwin-x64 |
darwin-arm64 | impit-darwin-arm64 | @ngrok/ngrok-darwin-arm64 |
linux-x64 | impit-linux-x64-gnu | @ngrok/ngrok-linux-x64-gnu |
linux-arm64 | impit-linux-arm64-gnu | @ngrok/ngrok-linux-arm64-gnu |
alpine-x64 | impit-linux-x64-musl | @ngrok/ngrok-linux-x64-musl |
alpine-arm64 | impit-linux-arm64-musl | @ngrok/ngrok-linux-arm64-musl |
linux-armhf (32-bit ARM) is not published: impit ships no arm-gnueabihf build, so an armhf VSIX would advertise airtableFormula.mcp.httpClient: "impit" and then fail with "Cannot find native binding". No untargeted fallback is published either, for the same reason.
The matrix is defined once in scripts/vsix-targets.mjs; versions and tarball hashes are pinned to pnpm-lock.yaml. scripts/package-targets.mjs builds every target and scripts/assert-vsix-binaries.mjs verifies each artifact contains exactly its own platform's .node files and no other's — byte-for-byte, against the SHA-256 digests in scripts/native-binary-digests.json, which are recorded from tarballs verified against pnpm-lock.yaml's integrity hashes. Filenames, package.json os/cpu, and a magic number are all labels an artifact carries about itself and cannot distinguish an x64 binary from an ARM64 one, or a glibc build from a musl one; an exact digest can.
Together these are eight target artifact packaging/assertion smokes — eight .vsix files built and their contents verified on one machine. They are not runtime smokes of eight native bindings: any single host can only load the binding compiled for itself, so only the host target's binding receives a genuine runtime load. Verifying the other seven by exact content is the strongest claim a single-host build can make about them.
The standalone npm package airtable-user-mcp is unaffected and stays universal — npm resolves the right optional dependency on your own machine at install time.
