Summary
This connects Claude to Exa's neural search engine, which uses semantic understanding rather than keyword matching to find web content. The source doesn't list specific tools, but Exa typically offers search and content retrieval operations that let you ask natural language queries and get back relevant pages with full text. You'd use this when you need Claude to find recent information or domain-specific content that goes beyond its training data. It's part of the Pipeworx gateway ecosystem, so you can either connect to this single integration or access it through their unified gateway alongside 700+ other data sources. Authentication and API key details aren't provided in the documentation.

Exa MCP — neural/semantic web search + content retrieval (exa.ai)
Part of Pipeworx — an MCP gateway connecting AI agents to 1476+ live data sources.
Tools
| Tool | Description |
|---|---|
search | Neural/semantic web search — find pages by meaning, not just keywords. Returns title, URL, published date, author, and relevance score. Optionally retrieve clean page text inline. Example: search({ query: "startups building AI agents for customer support", num_results: 10, type: "neural" }) |
get_contents | Retrieve clean, parsed page contents (text) for one or more Exa result IDs or URLs. Use after search to read the full content of pages. Example: get_contents({ ids: ["https://example.com/article"] }) |
find_similar | Find pages similar to a given URL using neural/semantic matching. Returns title, URL, relevance score, and published date. Example: find_similar({ url: "https://example.com/great-article", num_results: 10 }) |
Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"exa": {
"url": "https://gateway.pipeworx.io/exa/mcp"
}
}
}
What this endpoint actually serves
tools/list at https://gateway.pipeworx.io/exa/mcp returns the tools in the table
above plus the shared Pipeworx meta-tools — ask_pipeworx,
discover_tools, search_within, remember/recall and the rest of the
gateway-wide set. So the tool count you see is larger than this table: a
single-pack endpoint currently lists roughly 30 shared tools alongside the
pack's own. The connection's initialize response states its exact scope, and
is the authoritative answer for a given day.
This is deliberate, not multiplexing by accident. The meta-tools are what let a
scoped connection answer a question this pack does not cover — via
ask_pipeworx, which routes across the whole catalog — without you adding a
second MCP server. There is currently no way to mount a pack endpoint without
them; if the extra schemas cost you more context than the routing is worth,
connect to the full gateway once rather than to several pack endpoints.
Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Both URLs reach the same gateway and the same 1476+ data sources. The
only difference is which pack's tools are listed directly; ask_pipeworx
reaches all of them from either one.
Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:
ask_pipeworx({ question: "your question about Exa data" })
The gateway picks the right tool and fills the arguments automatically.

Our exa key is reserved for paid accounts, so an anonymous call to POST https://gateway.pipeworx.io/v1/tools/exa_search needs your own key passed as _apiKey alongside the arguments. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/exa_search. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.
