## Summary
`spec/mcp-server.json` (and the `McpServer` types generated from it for
both SDKs) has been frozen since the MCP beta landed. It is produced by
`mcp-gateway`'s `type-gen` from that repo's `docker-catalog.yaml`; this
refreshes it against a fresh snapshot of Docker's MCP catalog: **222 →
265 servers**.
Regenerated with the existing pipeline only — `packages/js-sdk: pnpm
generate:mcp` (`json2ts`) and `packages/python-sdk: make generate-mcp`
(`datamodel-codegen`). No hand edits.
- **49 new servers**: `n8n`, `neo4j`, `okta`, `temporal`, `proxmox`,
`testkube`, `thingsboard`, `zen`, `zscaler`, `googleFlights`,
`nextDevtools`, `victoriametrics`/`victorialogs`/`victoriatraces`, and
the AWS Labs family (`awslabsCloudwatch`, `awslabsDynamodb`,
`awslabsIam`, `awsPricing`, `amazonNeptune`, ...).
- **6 servers removed** — the catalog no longer ships them: `postgres`,
`root`, `tembo`, `flexprice`, `triplewhale`, `cdataConnectcloud`.
Passing them to `Sandbox.create` no longer type-checks, and since
`McpServerName = keyof McpServer`, `Template().addMcpServer('postgres')`
stops compiling too.
- **4 servers changed their options**: `awsDiagram` and `context7` now
require one (`outputDir`, `apiKey`), so `awsDiagram: {}` / `context7:
{}` no longer type-check; `onlyofficeDocspace` is down to `baseUrl` +
`docspaceApiKey`; `neo4jCypher` renamed keys.
- **71 entries differ in metadata**, but 61 of those are title-only and
10 description-only. Titles feed the generated TS interface names
(`AirtableMCPServer` → `Airtable`), which only matters to a caller who
imported those interface names directly — `mcp.d.ts` types are not
re-exported from the SDK root, only `McpServer` is.
The config is still forwarded to the gateway as written, so a dropped
server can be kept by casting past the type — whether it starts is up to
the gateway.
```ts
import { Sandbox } from 'e2b'
const sandbox = await Sandbox.create({
mcp: { n8n: { apiKey: process.env.N8N_API_KEY!, apiUrl: 'https://n8n.example.com/api/v1' } },
})
```
The catalog snapshot this was generated from:
https://github.com/e2b-dev/mcp-gateway/pull/3. The `mcp-gateway`
template has to be rebuilt from that snapshot for the new servers to
actually start in a sandbox, so that PR should land (and the template be
rebuilt) before or with this one.
### Known upstream defects, deliberately not hand-patched
Both come from `type-gen`'s naming rules and belong in
`e2b-dev/mcp-gateway`, since editing generated output here is undone by
the next regeneration:
- `vectraAiRux` lists `VECTRABASEURL` as required, but no such property
exists — the catalog maps it from `vectra_url` via the entry's `env`
block, and `type-gen` emits the env-var name verbatim. `type-gen` should
resolve `required` names through `env` and hard-fail on one that matches
no property.
- `VECTRACLIENTID` keeps its env-var spelling because `type-gen` strips
underscores without re-casing.

This adds (experimantal) support to add arbitrary MCP server from
Github.
```python
sbx = await AsyncSandbox.beta_create(timeout=600, mcp={
"github/modelcontextprotocol/servers": {
"install_cmd": "npm install",
"run_cmd": "sudo npx -y @modelcontextprotocol/server-filesystem /root",
},
})
```
or in TS with better typing:
```typescript
const sandbox = await Sandbox.betaCreate({
mcp: {
duckduckgo: {},
'github/modelcontextprotocol/servers': {
installCmd: 'npm install',
runCmd: `sudo npx -y @modelcontextprotocol/server-filesystem /root`,
},
},
timeoutMs: 600_000,
});
```
<!-- CURSOR_SUMMARY -->
---
> [!NOTE]
> Adds beta support to launch custom MCP servers (including
GitHub-defined ones) and updates MCP schemas/types; also switches
default MCP template to `mcp-gateway`.
>
> - **SDK (JS & Python)**:
> - Add beta support for `mcp` config, including dynamic GitHub-based
servers with custom `runCmd/installCmd/envs` and automatic `mcp-gateway`
startup with token.
> - Send `UNSET`/omit when `mcp` not provided to avoid API noise.
> - Change default MCP template from `mcp-gateway-v0-2` to
`mcp-gateway`.
> - **Types/Schema**:
> - Extend `McpServer` typings (JS `mcp.d.ts`, Python type hints) to
include many servers and descriptive metadata.
> - Introduce GitHub MCP types (TS `GitHubMcpServer`, Python
`GitHubMcpServerConfig`) and export in SDK surfaces.
> - Regenerate and enrich `spec/mcp-server.json` with
titles/descriptions and new server entries.

<!-- CURSOR_SUMMARY -->
> [!NOTE]
> Adds beta MCP support to JS/Python SDKs with template auto-selection,
config POST, MCP URL helpers, and codegen for MCP types/schemas.
>
> - **SDKs (Beta MCP support)**:
> - **JS SDK**:
> - Add `McpServer` types and export; extend `Sandbox.betaCreate` with
`mcp` option that auto-selects `mcp-gateway-v0`, configures MCP via POST
`/config` on port `50005` with retries, and expose `betaGetMcpUrl()`.
> - Add `wait(ms)` util; generate MCP types from `spec/mcp-server.json`;
new `generate:mcp` script and dev dep `json-schema-to-typescript`.
> - **Python SDK**:
> - Generate and export `McpServer` (TypedDict); extend sync/async
`beta_create` with `mcp` option, auto-select default MCP template, POST
MCP config with retries, and add `beta_get_mcp_url()`; define `mcp_port`
and `default_mcp_template`.
> - Makefile: add `generate-mcp` target; include
`datamodel-code-generator` in tooling; update lockfile/pyproject deps.
> - **Tooling**:
> - Add `spec/mcp-server.json` schema; update codegen Dockerfile to
install `datamodel-code-generator`.
