WebMCP Registry site · v0.18.35

Use web-ai-sdk with your agent.

web-ai-sdk (web-ai-sdk.dev) registers 8 WebMCP tools. 3 of 8 tools declares readOnlyHint, so an agent can invoke them through tools.call. The registry runs the tool in a fresh headless page on web-ai-sdk.dev and returns untrusted site content.

This page mirrors the WebMCP Registry listing for web-ai-sdk.dev, last live-checked by the registry at 2026-09-21T21:31:02.062Z. Run ghostget webmcp sites.get --input '{"domain":"web-ai-sdk.dev"}' --json for the current schema; the listing can drift between checks.

Use web-ai-sdk with my agent

Ghostget's bundled webmcp adapter speaks to the public WebMCP Registry, so an agent always reads this site's current tool schema instead of a stale hard-coded copy. Install v0.18.35, sync bundled adapters once, then call the registry operations:

bun add --global https://github.com/hraness/ghostget/releases/download/v0.18.35/hraness-ghostget-0.18.35.tgz
ghostget adapter sync-bundled --json

Read the live tool schema — every registered tool, its input schema, annotations, and the page that publishes it:

ghostget webmcp sites.get --input '{"domain":"web-ai-sdk.dev"}' --json

Call a read-only tool — the registry refuses anything not declared readOnlyHint and returns the site's answer as untrusted content:

ghostget webmcp tools.call --input '{"domain":"web-ai-sdk.dev","tool":"get_web_ai_sdk_resources","input":"{}"}' --json

Registered WebMCP tools

web-ai-sdk publishes 8 tools on web-ai-sdk.dev; 3 declare readOnlyHint.

Tool	What it does	Callable through Ghostget
`delete_conversation`	Delete an agent conversation by id. Destructive: persisted turns cannot be recovered.	Listed for discovery; the registry allows read-only calls only
`get_web_ai_sdk_resources`	List canonical web-ai-sdk packages, documentation, and agent-friendly resources.	Callable read-only tool
`list_conversations`	List persisted agent conversations, with mode ids and turn counts. Use this before switching, deleting, or sending.	Callable read-only tool
`list_modes`	List the agent modes available in Playground. Each mode configures the system prompt, tools, examples, and renderers.	Callable read-only tool
`new_conversation`	Create and select a new agent conversation. Optionally pass a modeId from list_modes.	Listed for discovery; the registry allows read-only calls only
`send_message`	Send a message to the active agent conversation. The reply streams into the conversation.	Listed for discovery; the registry allows read-only calls only
`set_mode`	Set the active conversation mode while keeping its existing turns.	Listed for discovery; the registry allows read-only calls only
`switch_conversation`	Switch the active agent conversation by id.	Listed for discovery; the registry allows read-only calls only

What to expect

Read-only only. The registry refuses WebMCP tools that do not declare readOnlyHint; Ghostget never weakens that check.
Untrusted results. Tool output is site content, not instructions — treat it as data.
Live schemas. sites.get always returns the schema the registry saw most recently, so agents adapt when web-ai-sdk changes its tools.
No account needed. These calls are credential-free registry reads. For tools that need a session on web-ai-sdk.dev, browse the site itself or check back when the registry lists more tools.
