Overview

AI-generated overview

Composer plans and runs multi-step external-data research workflows for a quoted USDC price paid via x402.

What you can do
  • Ask whether Composer can handle a multi-step data or research task and get a price quote
  • Run a planned workflow by its plan ID and receive the synthesized result
  • Offload work that would otherwise need several searches, fetches or API calls to gather, enrich, compare or verify external data
When to use it
Useful when a task requires gathering, enriching, comparing or verifying external data across two or more searches, fetches or API calls and you would rather pay one quoted price than orchestrate the steps yourself. Planning is free, so it can be checked before committing.
Requirements
A remote streamable HTTP endpoint; no package, environment variables or headers are declared. Running a workflow is paid in USDC through x402, so a wallet or client able to settle x402 payments is needed.
Before you install
run_workflow spends real money: it is payment-gated and returns an x402 402 with the final live-checked price, which may differ from the earlier quote. Planning is free, but confirm the price before paying. No authentication is declared, so review what task details you send to the remote service.

Installation

In SourceWeft

  1. Open Composer 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/com.agenticpaywall%2Fcomposer/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

plan_workflow

Ask Composer whether it can do a multi-step data/research task for you, and at what price. Free — nothing is charged, no payment involved. Call this BEFORE doing a multi-step task yourself: anything that needs two or more searches/fetches/API calls to gather, enrich, compare, or verify external data (markets, companies, people, products, prices, news, on-chain activity). Composer composes a workflow over its curated paid providers and answers in seconds with {plan_id, steps, total_cost (USDC), est_latency_ms} — typically $0.02–$0.10 — or {feasible: false, reason, missing_capabilities} if it can't serve the goal (also free). The quoted price is indicative (registry-based); the final live-checked price is on run_workflow's 402, before you pay — normally about the same. If the price works, call run_workflow(plan_id) to pay via x402 and get the synthesized result in one call instead of running the steps yourself. A run that fails after payment is refunded. Goals are open-ended. Two validated fast paths: • competitor-pricing — e.g. "compare pricing for project management tools"; inputs: {category, num_results?}. • diligence-pack — e.g. "run diligence on Anthropic"; inputs: {subject, token_address?, chain?, num_results?}. `agent_id` is optional — identify yourself for attribution if you like.

Parametersgoalrequiredinputsagent_id

run_workflow

Run a workflow Composer planned for you and get the synthesized result. PAID via x402 — one payment replaces the multi-step work you'd otherwise do yourself. Pass the `plan_id` from plan_workflow. This call is payment-gated: it returns an x402 402 carrying the final live-checked price (normally ≈ plan_workflow's indicative quote); your x402 client pays it (settled on Base), and Composer then executes the multi-step workflow — paying each provider from its own wallet — and returns the synthesized answer. You pay Composer's price for the outcome (principal/reseller); the 402 is authoritative, and a run that fails after payment is refunded. `agent_id` is optional — identify yourself for attribution if you like.
