Built-in tools
Understand the CoreSpeed-hosted capability rollout and use tools/list as the callable source of truth.
Built-in tools run on CoreSpeed-managed infrastructure and require no
third-party OAuth account. They share the same /mcp seam as connectors, so
identity, organization holds, API-key caps, activity recording, and capability
visibility still apply.
The authenticated engine inventory is not complete: GET /engines does not
exist yet. This page therefore does not publish a static engine catalog.
Use MCP tools/list; if a tool is absent there, it is not callable by the
current user and organization.
Available contract
Durable memory, Media and Social media research (TikHub) are the built-ins
callable today. Discover their live names and schemas in tools/list; do not
derive them from the retired public /catalog.
Eight durable-memory operations, free per call and still protected by the organization boundary.
Generate image, video, or audio and understand supplied media through one capability. Billable calls are metered; generated outputs use signed artifact URLs.
Public TikTok, Douyin, Xiaohongshu, Instagram, YouTube, X and Reddit data through one tikhub__ namespace on CoreSpeed's own TikHub account. Billed per successful request; failures never charge.
The exact built-in names and schemas visible to the authenticated caller.
V0 rollout
Media generation and understanding ship together. Web remains in validation
until its tools are returned from tools/list.
| Capability | Intended surface | Current public status |
|---|---|---|
| Media | media__list_models, media__generate, media__create_upload, media__understand; signed artifact outputs | Available |
| Social media research | tikhub__* — 38 read tools: search, profiles, posts/videos, comments, trends and YouTube captions across TikTok, Douyin, Xiaohongshu, Instagram, YouTube, X and Reddit | Available |
| Web | web__search for ranked source material and web__scrape for one URL to clean Markdown | Validation / hidden |
Media calls force safety controls and cap cost-driving parameters on the server. Web search will return source material rather than a second synthesized answer, and v0 scraping will be single-page only—no crawl queue.
Social media research needs no TikHub account: the platform holds the key,
every tool is read-only public data, and each successful request bills a flat
credit rate per endpoint class (Instagram and YouTube captions bill a higher
premium rate; the captions result poll is free). Tool inputs are typed per
platform — the exact parameters are in tools/list.
The former experimental image-gen__* tools are no longer callable. Use
media__generate for image generation.
Authenticated tools/list remains the authority for whether any tool is
callable by a particular user and organization.
