Overview

AI-generated overview

A remote execution node giving AI agents paid microservices: web extraction, on-chain risk and price oracles, agent scratchpad locks, RFP auctions, bounty escru

What you can do
Fetch and compress web pages or PDF/DOCX documents into token-efficient Markdown, and trim or repair LLM context and JSON output. Query time, DEX prices, Base gas, and inspect wallet or contract risk and sanctions status. Share state across agents with a scratchpad, distributed locks, rate limiting and idempotency keys. Run a reverse-auction RFP market and task bounty escrows with claims, proofs and payouts. Provision temporary webhook listeners, cron triggers, transaction simulation and random or temporal oracles.
When to use it
Useful when building multi-agent or autonomous workflows that need shared state, coordination primitives, on-chain data, or paid utility calls without running your own infrastructure. Also relevant for agents that must clean up web content, malformed JSON or oversized context before inference.
Requirements
A remote SSE endpoint; no local package. No authentication is declared, but most tools are billed per call in USDC on Base or Solana, so a funded wallet and payment flow are implied. Some tools take EVM wallet addresses as identifiers.
Before you install
Most tools cost USDC per call, and escrow, bounty and RFP tools move or lock funds, with payouts described as irrevocable. Wallet addresses are used as buyer, worker and creator identities. Webhook listeners expose a temporary public callback URL and return a secret key. Fetched URLs and submitted payloads are sent to a third-party service.

Installation

In SourceWeft

  1. Open Project Sairen - Agentic Execution Node in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via SSE. 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/ca.omniapps%2Fsairen/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
