web_search_exa
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 about any topic. Returns: Clean text content from top search results. Query tips: describe the ideal page, not keywords. "blog post comparing React and Vue performance" not "React vs Vue". Use category:people
query string · required
Natural language search query. Should be a semantically rich description of the ideal page, not just keywords. Optionally include category:<type> (company, people) to focus results — e.g. 'category:pe
numResults number
Number of search results to return (default: 10).
A call is made on an account: it counts against an allowance and the publisher sees it, which is why this one asks who you are first.

What it does
Neural web search built for agents. Built from exa-mcp-server and run on mcprush hosting: there is no endpoint to keep alive and nothing to deploy yourself. The image is pinned, so what answers today is what answered yesterday.
Quickstart
# 1 — buy it first ($29 a month): mcprush.com/checkout?server=exa-search-hosted-mcp
# a key alone is not enough: the gateway refuses every call until it is bought
# 2 — sign in with a key of the account that bought it: npx mcprush@latest login
# the key is at mcprush.com/dashboard#access
# 3 — install
npx mcprush@latest add mcpdevpro/exa-search-hosted-mcp
# 4 — ask your agent for something these tools do
# web_search_exa, web_fetch_exa
Windows PowerShell says 'running scripts is disabled on this system'? Run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned once, or type npx.cmd instead of npx (codex.cmd, gemini.cmd, grok.cmd likewise). PowerShell 7 needs neither.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine — this server runs on infrastructure we host behind our gateway, and what you install is the connection to it.
Claude Codedeclared by this listing
Claude Code has its own MCP command, and the key rides on it as a header — the gateway refuses a call that carries none. Claude Code reads MCPRUSH_KEY each time it connects, so the key stays out of its config: export your key from Access in your shell profile (macOS, Linux), or run setx MCPRUSH_KEY <your key> and open a new terminal (Windows). Or let npx mcprush@latest add mcpdevpro/exa-search-hosted-mcp write the entry with the key for you; --scope user makes it available in every project. The first connection after a quiet spell starts the server, which takes up to a minute: if your client says it failed to connect, reconnect after that (/mcp in Claude Code).
Buy it first — $29 a month. A key alone is not enough: until this account has bought it, the gateway refuses every call. Subscribe, then use a key of the account that bought it.
claude mcp add --transport http --scope user exa-search-hosted-mcp https://mcprush.com/gw/exa-search-hosted-mcp/mcp --header 'Authorization: Bearer ${MCPRUSH_KEY}'Reconnect, or start a new session, and the tools appear in the model’s tool list.
This is a paid listing: the gateway answers only a key of an account whose subscription to it is active — how the login works. Until then add writes nothing: signed out, it names the price and the checkout link; signed in, it prints the checkout link, or why the subscription is held (ended, paused, an unpaid invoice) and the link that lifts it. The gateway refuses every call the same way, and most clients only show the server as failed.
What it asks of you
It reaches a system of yours, so it needs your own credential rather than the publisher’s: EXA_API_KEY — Your Exa API key, from dashboard.exa.ai/api-keys.. You set it after installing; the value is sealed here and handed to the server when it starts.
What it writes
One config entry pointing at the gateway. The server itself runs on infrastructure we host, so nothing from this listing executes on your machine.

| numResults | number | no | Number of search results to return (default: 10). |
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 content from known URLs. Batch multiple URLs in one call. Returns: Clean text content and metadata from the page(s).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| urls | array | yes | URLs to read. Batch multiple URLs in one call. |
| maxCharacters | number | no | Maximum characters to extract per page (default: 3000) |
Starter
$29 / month
- 50,000 calls a month, included
- 120 calls a minute at peak
- Every tool the listing has
- Cancel any time — the unused days are credited
- Runs behind the gateway, so cancelling stops it
What counts against the 50,000 calls a month on Starter
| Tool | Unit | Calls used | Out of the monthly allowance |
|---|---|---|---|
| web_search_exa | call | 1 | 0.0020% |
| web_fetch_exa | call | 1 | 0.0020% |
Failed calls, timeouts and anything the gateway rejects never count. When the allowance runs out the gateway returns an error naming the plan limit — nothing is billed beyond the subscription, ever.

ATrust score 100 / 100
Scanned: 3.4.2 · 14 Oct 2026
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.

Implementation sourceread
Package metadataread
Live transportnot available
No tools were enumerated, so prompt-injection, capability and toxic-flow analysis had no tool surface to inspect. To grade a package’s real runtime tools, scan the running server: --command "npx -y <package>".
Capability — what it could do if the model were manipulated
Tags derived from each tool’s schema and the implementation, not from what the tool calls itself. minimal is the level these add up to.
| Tool | Capability tags | Why the tag was assigned |
|---|---|---|
| No per-tool rows for this release — see the note below. | ||
No tool surface was enumerated, so there is nothing to attribute a capability to.
Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.

This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
Release history
The gateway serves every install the publisher’s current release, so a release cannot be pinned or rolled back to here yet. The history below is for reading; the current release on file is 0.1.0.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish Exa Search can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
