WebMCP: Agent Tools on AI Spectrum

This site exposes browser-side tools via the WebMCP API (navigator.modelContext) for agents running in a real browser context (e.g. Playwright, Comet, Atlas). Agents that can only fetch HTML without executing JS can read the static manifest instead.

Available tools

searchBlog

Full-text search over AI Spectrum posts and pages.

Param	Type	Description
query	string	Keyword(s) to search across post titles, descriptions, and body text

compareModels

Compare two AI models by their HLE (Humanity's Last Exam) and GPQA Diamond benchmark scores.

Param	Type	Description
model1	string	Name of the first model, e.g. 'Claude Opus 5'
model2	string	Name of the second model, e.g. 'GPT-5.4'

getModelInfo

Get a single AI model's HLE and GPQA Diamond benchmark scores.

Param	Type	Description
model	string	Name of the model, e.g. 'Claude Opus 5'

All three tools are read-only (readOnlyHint: true) and require no authentication.

Calling the tools from a browser-executing agent

const tools = await navigator.modelContext.listTools();
const result = await navigator.modelContext.executeTool("searchBlog", { query: "WebMCP" });

Static manifest for non-JS agents

If your agent only fetches HTML, read the schemas directly instead of executing JS:

• /webmcp-manifest.json
• /.well-known/webmcp.json (same content, conventional path)
• Inline JSON-LD (#webmcp-manifest) embedded on every page
• /llms.txt for a plain-text summary
