Overview

AI-generated overview

A remote, pay-per-call web search gateway that gives an assistant plain or AI-summarized search results, paid in USDC via x402 or bypassed with a Forge key.

What you can do
Run web searches and get structured results with title, URL and snippet for each hit, with an optional result limit per query. Request an enriched search that returns the same results plus a Claude-generated, source-cited summary. Discover the available tools without authenticating, then pay per call or authenticate with a Forge key to skip payment.
When to use it
Useful when an assistant needs live web search results or a quick sourced summary and you would rather pay per query than manage a search API subscription. A reasonable fit for agents that already handle x402 payments or hold a Forge key.
Requirements
A remote streamable HTTP endpoint; nothing to install locally. No account or API key is needed to list tools. Paid calls require an x402 v2 payment in USDC on Solana mainnet; alternatively supply an fnet_ Forge key as the api_key argument or an Authorization Bearer header. Network access to the endpoint is required.
Before you install
Each search costs money: $0.005 per basic query and $0.02 per enriched query, settled in USDC on Solana mainnet, so automated loops can spend funds. A Forge key is a credential and should be kept out of logs and shared transcripts. Queries are sent to a third-party service that forwards them to SearXNG and DuckDuckGo and, for enriched searches, to Claude.

Installation

In SourceWeft

  1. Open Foundrynet Search in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.FoundryNet%2Ffoundrynet-search/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Add this to your client's mcpServers config.

README

FoundryNet Search

x402-gated web search gateway for AI agents. Structured results, or an AI-summarized sourced answer. No API keys, no accounts.

Part of the FoundryNet Data Network. Pay-per-call in USDC (x402) or bypass with an fnet_ Forge key. Also exposed as an MCP server for Smithery/Glama/Claude.

Tools / Endpoints

Tool / RoutePriceDescription
search — POST /v1/search$0.005{query, max_results?} → [{title, url, snippet}]
search_enriched — POST /v1/search/enriched$0.02{query} → results + a Claude-generated, source-cited summary

Backends: SearXNG (JSON, if SEARXNG_URL configured) + DuckDuckGo (HTML) — free. Enrichment via Claude.

MCP

Streamable HTTP endpoint: https://foundrynet-search-production.up.railway.app/mcp

claude mcp add --transport http foundrynet-search https://foundrynet-search-production.up.railway.app/mcp

Tools list without auth (discoverable). Pass an fnet_ key as api_key (or Authorization: Bearer) to bypass payment; otherwise the tool returns an x402 payment_required object.

Payment (x402)

Standard x402 v2 on Solana mainnet USDC. Discovery: GET /x402, GET /.well-known/x402, per-route 402 at GET /x402/{route}. Validated on 402 Index.

Volume play — every agent needs web search, and $0.005/query is cheaper than most alternatives.
