# Exa MCP MCP Server

> **Exa MCP MCP Server** is a hosted, multitenant Model Context Protocol (MCP) server run by **MewCP** (https://mewcp.com), giving AI agents managed access to Exa MCP.
>
> MewCP takes care of all MCP infrastructure for you — credential storage, OAuth flows,
> token refresh, and production-grade auto-scaling — so your AI agents can connect to
> third-party services and run freely without you managing any MCP server yourself.

## About

Exa is a neural search engine built for finding information by meaning rather than just matching keywords. Search the web for relevant articles, research papers, company information, code, and news; extract clean content from webpages; find similar links; and retrieve structured results with source metadata for research and AI applications.

## Details

- Server ID: `exa-mcp`
- Version: 3.5.0
- Tools: 3
- Authentication: OAuth, managed by MewCP
- Transport: http

## Access

The gateway URL below serves your **entire MewCP toolset**, not this server on its
own. Pasting a config snippet is not enough — Exa MCP has to be in the toolset
first. In order:

1. Add Exa MCP to your toolset at https://mewcp.com/mcp/exa-mcp
2. Connect your Exa MCP account (OAuth); MewCP stores the credential and attaches it to each call
3. Add the gateway URL to your client (see Connect below). It signs in with OAuth
   the first time it connects, so there is no key to copy.

Once connected, an agent does **not** see this server's tools as top-level tools.
It sees four meta-tools and reaches everything through them:

- `search(query)` — find tools by keyword across the toolset
- `get_schema(tools)` — full description and arguments for the tools you picked
- `list_accounts(provider)` — only when one app has several connected accounts
- `call_tool(server_maskedId, tool_name, args)` — execute

So the list below is what `search` can return for this server, not a set of
callable tool names on their own.

## Tools (3)

Descriptions are truncated to 160 characters; call `get_schema`
for the full text and the argument schema. Where a tool is annotated, its type
is shown — treat `destructive` as irreversible.

- `web_search_exa` _(read)_ — Search the web for any topic and get clean, ready-to-use content. Best for: Finding current information, news, facts, people, companies, or answering questions…
- `web_fetch_exa` _(read)_ — Read a webpage's full content as clean markdown. Use after web_search_exa when highlights are insufficient or to read any URL. Best for: Extracting full…
- `agent_run` _(read)_ — Start or resume an Exa Agent run for multi-step research, list-building, or enrichment. Use it instead of running many searches yourself when a task needs…

## Connect

- URL: https://gateway.mewcp.com/personal/mcp
- Transport: Streamable HTTP (remote). Nothing to install.
- Sign-in: OAuth. On first connect the client opens a browser window to sign in
  to MewCP and approve access. No API key.
- Headless clients (SDKs, servers without a browser) send an API key instead:
  `Authorization: Bearer <API_KEY>`, key from https://mewcp.com/dashboard/api-keys
