Anthropic Claude Messages API MCP server — chat, vision, web search, extended thinking
Claude MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. Anthropic Claude Messages API MCP server — chat, vision, web search, extended thinking.
An MCP (Model Context Protocol) server for the Anthropic Claude Messages API. Built in Rust, it exposes chat, vision, live web search, and model listing as MCP tools — so any MCP client (Claude Desktop, Claude Code, etc.) can consult Claude as a tool.
Once Claude is connected, these are the calls the assistant has available:
chat — Send a message to Claude. Supports multi-turn history, a system prompt, model selection, and extended thinking via thinking_budgetchat_with_vision — Analyse an image given an image URL and a text promptchat_with_search — Chat with live web search — Claude searches server-side and answers with cited sourceslist_models — List available Claude models and their IDs (cached for 5 minutes)Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.
Plenty of search and retrieval servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Claude's toolset — chat, chat_with_vision, chat_with_search and 1 more — is a fair guide to whether it matches your workflow. It is maintained by codeChap; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
| Tool | What it does |
|---|---|
| chat | Send a message to Claude. Supports multi-turn history, a system prompt, model selection, and **extended thinking** via thinking_budget. |
| chat_with_vision | Analyse an image given an image URL and a text prompt. |
| chat_with_search | Chat with live **web search** — Claude searches server-side and answers with cited sources. |
| list_models | List available Claude models and their IDs (cached for 5 minutes). |
The simplest web tool that matters — fetch any URL and get model-ready markdown back.
Industrial-strength web extraction — render, scrape, crawl and search entire sites into clean markdown.
Puppeteer-powered browser control that drives pages from the accessibility tree instead of pixels.
Search built for AI, not humans — semantic web search that returns model-ready content, plus code context.
Answers, not links — delegate questions to Perplexity's search-grounded models and get cited responses back.
Put 6,000+ pre-built scrapers at your assistant's fingertips through one MCP endpoint.
