}Transloadit MCP Server (Streamable HTTP + stdio), built on top of @transloadit/node.
The hosted server lives at:
Add it to your MCP client by URL. The client discovers API2 as the OAuth authorization server, opens a browser consent page in the Transloadit Console, and keeps a short-lived token plus refresh token for you. No API keys leave your Workspace.
The hosted endpoint asks you to sign in before any tool runs, Robot docs and linting included, because MCP clients only start OAuth when the endpoint challenges them. Robot docs and linting ask for no scopes. To use them without an account, run the server yourself (see Self-hosted).
For non-interactive runs (for example claude -p), explicitly allow MCP tools:
Settings → Connectors → Add custom connector → enter https://api2.transloadit.com/mcp. Claude
registers itself with API2 and opens the consent page.
Settings → Apps & Connectors → Advanced → Developer mode → Create, then enter the URL above with
authentication set to OAuth. Files you attach in the chat are handed to
transloadit_create_assembly as attachments; results render in the Assembly result widget.
The plugin manifest for the ChatGPT and Codex catalog (plugin.json, mcp.json and the
.codex-plugin/plugin.json fallback) lives in this package directory. It points at the hosted
server and at the Agent Skills catalog at https://transloadit.com/.well-known/skills/index.json
instead of bundling skill files.
Codex opens the consent page right away. To sign in again later, run
codex mcp login transloadit.
Or in ~/.codex/config.toml:
~/.cursor/mcp.json:
Where no browser is available, mint a bearer token from an Auth Key and pass it as
Authorization: Bearer <token>:
Generate this token in a trusted environment (backend, CI, or local shell), then hand it to the agent runtime. You can mint it via:
npx -y @transloadit/node auth token --aud mcpPOST https://api2.transloadit.com/token (HTTP Basic Auth with key/secret)Transloadit with authKey + authSecret, then call
client.mintBearerToken({ aud: 'mcp' })Interactive CLI sessions can also run npx -y @transloadit/node auth login (device flow) and reuse
the stored credentials.
Bearer tokens satisfy signature auth on API2 requests; signature checks apply to key/secret requests.
Run the server where your agent runs, set TRANSLOADIT_KEY and TRANSLOADIT_SECRET, and the server
handles API auth automatically.
Auth Keys sign with one HMAC algorithm. Keys created in the Console with "Allow signing Smart CDN
URLs" (the default) require sha256, so add TRANSLOADIT_SIGNATURE_ALGORITHM=sha256, as the
Console's snippet for the key shows. Other keys use the default sha384. A mismatch fails with
mcp_invalid_signature, and its hint names the algorithm the key requires.
When binding HTTP mode to non-localhost hosts, TRANSLOADIT_MCP_TOKEN (or the hosted-mode
TRANSLOADIT_MCP_RESOURCE_METADATA_URL) is required.
For HTTP mode via Docker, override the stdio entrypoint, expose the port, and set a transport
token, which binding to 0.0.0.0 requires:
TRANSLOADIT_MCP_TOKEN explainedTRANSLOADIT_MCP_TOKEN is a self-hosted MCP transport token. It protects your own HTTP MCP endpoint
(npx -y @transloadit/mcp-server http), not API2.
Authorization: Bearer <TRANSLOADIT_MCP_TOKEN>./token.https://api2.transloadit.com/mcp.Generate one, then start HTTP mode:
Most self-hosted users add the server to their MCP client and let the client start it via stdio.

Every tool carries title, readOnlyHint, destructiveHint, idempotentHint and
openWorldHint annotations. transloadit_create_assembly is the only destructive one: export
Robots such as /s3/store can overwrite files at their destination, so hosts should confirm it.
transloadit_lint_assembly_instructions validates complete, merged instructions locally. It does
not fetch the Template named by template_id: resolve the Template and merge any Assembly or
replay overrides before linting. For example, an OCR Step that inherits ocr_provider must
include that provider in the instructions passed to this tool.
securitySchemes depend on how the server runs: hosted (TRANSLOADIT_MCP_RESOURCE_METADATA_URL)
declares oauth2 with the scopes above for every tool; a server holding TRANSLOADIT_KEY and
TRANSLOADIT_SECRET declares noauth everywhere; otherwise the account tools declare oauth2 and
the others noauth. TRANSLOADIT_MCP_TOKEN and TRANSLOADIT_MCP_RESOURCE_METADATA_URL cannot be
combined.
Authenticated tools/list is the reference for outcome shortcuts, descriptions and field schemas.
The synced alphalib Builtin manifest supplies
reviewed version pins and temporary field exclusions. The MCP adapter derives tool names and
titles from those IDs and consumes the catalog schema through @transloadit/zod/v4/builtinTemplates.
An alphalib sync carries approved additions, renames, removals and gate changes without another
MCP registry.
Each shortcut’s description starts with the tool-ready summary API2 authors beside the Builtin
definition: the credential’s catalog summary once read, and otherwise the synced
mcpBuiltinTemplateSummaries, which the server card and pre-catalog tools/list use. The long
catalog description is not tool text. Standalone draft-07 fields_schema and content.fields
defaults come from API2’s Template catalog. Defaults merge before validation, preserving JSON types; conservative schema
annotations leave runtime cross-field validation authoritative. A null or absent contract makes
that shortcut unavailable. Generic tools keep their existing behavior.
The manifest’s temporary legacy VP8 webm gate remains until
api2#9960 is deployed and verified.
Social captions are deferred. Transcription language hints do not translate speech.
Catalog reads have a three-second overall deadline without retries. During an authenticated
catalog outage the reviewed names remain discoverable with permissive fields; each call still
fetches and validates the current contract. Malformed or default-sensitive composed schemas also
use permissive discovery, followed by full validation after merging defaults at execution.
Supply fields and the same files/attachments/upload/wait options as transloadit_create_assembly.
For a sandbox file, set expected_uploads, run the returned upload command, then call
transloadit_wait_for_assembly. The SDK already includes the
document extraction registry fix.
transloadit_list_templates supports:
include_builtin: all, latest, exclusively-all, exclusively-latestinclude_content: include parsed steps in each template itemBuiltin items also carry fields_schema unchanged, including conservative-fidelity metadata
and null for older Builtins without a declared schema. Workspace Templates omit that property.
transloadit_get_profile returns { id, name?, nickname? } for the Workspace behind the current
credentials, derived from the Workspace's own Assemblies or Templates.
transloadit_create_assembly and transloadit_wait_for_assembly link the MCP Apps resource
ui://transloadit/assembly-result (_meta.ui.resourceUri, also _meta["openai/outputTemplate"]).
Hosts that support MCP Apps render each Step's results with image, video and audio previews,
download links, an "Open in Console" link and a "Save as Template" shortcut. It speaks the MCP Apps
2026-01-26 protocol (ui/initialize with appInfo) and also reads ChatGPT's window.openai.
Its CSP allows https://*.transloadit.com, https://*.transloadit.net and https://*.r2.dev
(result buckets); override the list with TRANSLOADIT_MCP_RESULT_DOMAINS or resultDomains.
ChatGPT asks for the exact hosts a widget uses, so a deployment that knows its result buckets
should list them as origins instead of wildcards. ChatGPT also needs redirect_domains to open
links from the widget: the server sends the result origins plus the Console origin there. ChatGPT
serves the widget from the origin in _meta["openai/widgetDomain"]
(TRANSLOADIT_MCP_WIDGET_DOMAIN). ui.domain stays unset, because Claude derives that value from
the server URL and rejects any other.
Hosts that attach chat files (ChatGPT) pass them under attachments instead, as declared by
_meta["openai/fileParams"]:
Each attachment becomes a URL input (attachment_1, attachment_2, …) and follows the URL rules
below.
If the file exists only locally or in your sandbox, call transloadit_create_assembly with
expected_uploads and run the returned upload_instructions; this needs outbound HTTPS from the
sandbox to Transloadit (Claude.ai: Settings → code execution network access must allow it). Hosts
such as Claude.ai do not hand chat attachments to connector tools, and base64 in tool arguments is
impractical for anything but tiny files, so the agent uploads the file itself:
transloadit_create_assembly with your instructions and expected_uploads: 1 (one per
file, at most 100 per call). The call returns right away, even with wait_for_completion: true,
because the Assembly now waits for those uploads.upload_instructions entry has the tus endpoint, the tus metadata (assembly_url,
fieldname) and a ready-to-run curl command. Set FILE to the file's path and run it in a
bash shell; it prints 201 once the file is uploaded (tus creation-with-upload, one request).transloadit_wait_for_assembly with the Assembly URL.Calling transloadit_create_assembly with assembly_url and expected_uploads (all uploads the
Assembly expects, as at creation) hands out upload_instructions for the uploads an existing
Assembly still waits for.
The commands contain no credentials: the Assembly URL is the only capability, and it lets the holder add files to that one Assembly while it waits for uploads.
These limits apply to inline JSON/base64 payloads. For larger files, use a public URL or upload from
your own machine with npx -y @transloadit/node upload.
maxBase64Bytes: 512,000 decoded bytesSet maxRequestBodyBytes (handler option or JSON config key) to change the body limit; larger
requests get HTTP 413 and are not buffered. Express apps that install their own body parser set
its limit there.
URL inputs that the server downloads (for templates that expect uploads) are capped at 1 GiB in
total per call and 10 minutes per download, redirects included; set maxUrlDownloadBytes and
urlDownloadTimeoutMs to change that. On the hosted
endpoint the caller's token is checked with API2 before anything is downloaded. Downloads count
toward the wait budget below: when they do not finish in time, no Assembly is created and the call
returns mcp_preparation_timeout, so a retry is safe. The download is stopped about a second
later and its file removed.
MCP hosts abandon tool calls that run too long (ChatGPT after about a minute) and may retry them,
which would create a second Assembly. transloadit_create_assembly, the Builtin shortcuts and
transloadit_wait_for_assembly therefore wait at most 45 seconds, even with a larger
wait_timeout_ms/timeout_ms. When that budget is spent, the call returns the Assembly with its
current status (a last status read or a slow creation request may take up to 5 seconds more, so
keep the budget that far below the host's limit), running: true and an mcp_assembly_still_running notice; uploads and processing
continue, and transloadit_wait_for_assembly or transloadit_get_assembly_status follow it. Set
maxWaitMs (option or JSON config key) or TRANSLOADIT_MCP_MAX_WAIT_MS to change the budget.
For URL inputs, behavior depends on the template/instructions:
/http/import Step exists, MCP sets/overrides that Step's url.:original or /upload/handle), MCP downloads then uploads via
tus. These downloads require public HTTP(S) URLs; private-network targets are rejected, including
redirects to private addresses.allow_steps_override=false and only /http/import would work, URL inputs are rejected.The Builtin shortcuts for caption-video, convert-to-pdf, encode-video, extract-text,
prepare-image, remove-background, transcribe and video-covers send URLs to API2 as
input_url next to template_id when every file
and attachment of the call is a URL (up to 10, one for caption-video). Transloadit then fetches
the files itself, so the Assembly exists at once and nothing is downloaded by the MCP server or held
up by a large file. API2 names the files after their URLs (or redirects and Content-Disposition),
so inputs given a file name, such as host attachments, keep the download path above, as do calls
that mix URLs with base64 files or sandbox uploads, calls with upload_behavior: 'none', and URLs
that API2 would refuse (whitespace, |, ${…}, over 4096 characters). If API2 refuses
input_url for the request, its error is returned like any other. The eligible Builtins are listed
in the alphalib Builtin manifest.
kind: 'path' must switch to base64, a public URL,
or a local CLI upload. This also applies to stdio and self-hosted servers.url inputs, small base64 payloads, or upload locally with
npx -y @transloadit/node upload.expected_uploads to keep an Assembly open for out-of-band tus uploads.If assembly_url is provided, MCP resumes uploads using Assembly status (tus_uploads +
uploads). This requires stable field names and file metadata (filename + size).
Resubmit the same base64 or public URL input to resume an upload. URL inputs are downloaded and
uploaded even when the original instructions are omitted; resumption does not modify the existing
Assembly's Steps. The file's contents, field name, and filename must remain unchanged.
This resumes tus uploads; URL imports performed by /http/import do not need to be resubmitted.
Assembly IDs must contain 32 hexadecimal characters. Assembly URLs must refer to a Transloadit host
or the explicitly configured API origin, without credentials, query parameters, or fragments.
MCP extracts the ID and resolves the Assembly through its configured API endpoint; it never fetches
the caller-supplied Assembly URL directly. MCP does not follow API response redirects, including an
Assembly's redirect_url. A custom endpoint can use a local origin for development,
but this does not enable private-network URL file downloads.

Lint Assembly Instructions
Lint complete, merged Assembly Instructions without creating an Assembly. Resolve template_id and merge any Template or replay overrides before calling; this tool does not fetch Templates. Returns structured issues.
strictinstructions必填return_fixedCreate or resume an Assembly
Create an Assembly from instructions (Steps or a template_id), or resume one by assembly_url, optionally uploading files and waiting for completion. Files attached in the chat arrive under attachments; public URLs and small base64 payloads go under files. If a file exists only locally or in your sandbox, set expected_uploads and run each returned upload_instructions curl command there (it needs outbound HTTPS to Transloadit). Waiting stops after a server budget (45 seconds by default). Returns the Assembly with its result files; running: true means it is still processing, and next_steps say how to follow it instead of creating it again.

Transcribe the speech in videos and burn plain captions into each original video. Returns the captioned video and its SRT captions. Fields set the caption font_size (default 16), position, font_color and border_color. The automatic provider detects the spoken language; target_language (such as french) hints it, and source_language (default en-US) sets it for provider aws or gcp. Captions are never translated. Pass the Builtin’s parameters under fields. Provide inputs as attachments (files shared in the chat), files (public URLs or small base64 payloads) or expected_uploads (files that exist only locally or in a sandbox; the result returns an upload_instructions curl command per file).

Capture a public HTTP(S) webpage (url) or an uploaded HTML file as a PNG, JPEG or PDF. Returns one image or PDF per captured page. Defaults to a full-page PNG 1024 pixels wide; set fullpage to false for a fixed width × height viewport, and use delay or wait_until for late-loading pages. A url takes precedence over uploaded HTML. No custom headers, credentials or browser actions are sent. Pass the Builtin’s parameters under fields. Provide inputs as attachments (files shared in the chat), files (public URLs or small base64 payloads) or expected_uploads (files that exist only locally or in a sandbox; the result returns an upload_instructions curl command per file).

Extract text from images, PDFs and Office documents as plain text (default) or JSON. Returns one text result per input by default. Images use OCR; documents try embedded text before OCR, and Office files are converted to PDF first. Fields set text_method, the OCR provider (AWS or GCP), page_range, password and text_granularity, where page returns one result per page; those last three need native extraction. Unsupported formats are skipped. Pass the Builtin’s parameters under fields.
