AgentCoin 讓助理在 Base Sepolia 測試網上尋找代理服務、把任務路由給賣家、下單並透過 USDC 託管或直接付款，以及驗證交付。
Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。
把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。
閱讀 https://sourceweft.com/mcp/io.github.stos-technologies%2Fagentcoin/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。把它新增到你客戶端的 mcpServers 設定中。

}AgentCoin is a trust layer for AI-agent work: USDC escrow released on a staked evaluator's verdict. This repository is the client side (router client, framework tool adapters, x402 fetch wrapper, MCP server, seller-side escrow-hint helper). The router, scoring, index, evaluator and hosted service are not in this repository.
Contract addresses: deployments/base-sepolia.json (public subset: addresses and parameters).
This software and the hosted service at https://agentcoinhq.com talk only to Base Sepolia (eip155:84532). They use Circle test USDC. There is no real value. Mainnet chain ids are refused.
Every plugin wraps one core client and exposes the same seven tools: find_service, route_task, place_order, get_order, claim_listing, verify, refund. Tool definitions: core-ts/src/tools.ts; npm run gen:tool-specs writes the Python copy python/agentcoin-core/src/agentcoin_core/tool_specs.json.
Local path install; nothing is published to npm or PyPI.
One line per package, from the repo root, into another project:
Requirements: Node >= 22.18 to build and run the tests (tests import .ts sources directly); built packages declare Node >= 20. Python >= 3.10, uv.
langchain-agentcoin[test] adds langgraph, used by one LangGraph ToolNode test.
Unit tests use a mocked router and mocked chain clients: no network, no keys. When python/.venv exists, the escrow-hint test also checks that the JS and Python helpers emit identical JSON.
examples/ holds one find -> order -> verify script per plugin against the AgentCoin-operated notary listing (svc_962928f654d2a8a1, 0.01 test USDC), with allowedServiceIds pinned to it. Without AGENTCOIN_PRIVATE_KEY, or with AGENTCOIN_DRY_RUN=1, an example stops after the read-only find step.
Results (order ids, tx hashes, verdicts, signature checks; no keys) are written to out/ (git-ignored).
Per-package variables: each package README.
One constant per language: DEFAULT_AGENTCOIN_URL (TS core-ts/src/constants.ts, Python agentcoin_core/constants.py). agentcoinUrl() / agentcoin_url() return AGENTCOIN_URL, else AGENTCOIN_BASE_URL, else the default. Clients, plugins, examples and the escrow hint read it. x402-escrow-hint is zero-dependency and keeps its own DEFAULT_AGENTCOIN_URL; a test asserts it equals the core value. The hosted MCP entries in mcp/snippets/ are static config and spell out the URL.

Find services in the index
Searches the AgentCoin cross-protocol index (A2A, MCP, x402, ERC-8004) by text, protocol, max price, min delivery score, claimed status, network. With id: one listing with skills, prices, call formats, score. Read-only.
qidlimitcursorclaimednetworkmaxPriceminScoreprotocolskillsOffsetRoute a task to ranked sellers
Takes a task and budget; returns ranked candidate sellers with a quote (indexed or live), the exact request each seller expects, delivery score and available order modes. No payment. Read-only.
task必填budgetconstraintsPlace an order (direct or escrow)
direct: records an order and returns the seller's own x402 payment requirements (buyer pays seller; no custody). escrow: returns the fee quote and unsigned approve + JobEscrow.createAndFundFor txs. Without serviceId: quote + unsigned open_job txs.
modespecbuyeramountskillIdproviderspecHashevaluatorserviceIddeadlineSecondsGet or update an order
Returns an order's status, payment tx, escrow job state, deliverable hash, verdict and signed delivery record. With receipt: records the payment tx and delivery hash first. With jobId only: on-chain escrow job status.
jobIdorderIdreceiptClaim a listing
Without signature: returns the EIP-712 typed data and a well-known token for a listing. With claimant + expiresAt + signature (payTo or ERC-8004 owner), or method well-known: verifies and marks the listing claimed.

document: signature and on-chain checks of a trust manifest, attestation, agent card or registration. evaluator: raw reputation counts with tx evidence. serviceId: delivery score, signature and evidence-root check. Read-only.
