概覽

AI 產生的概覽

付費遠端 MCP 伺服器，依現行 API 審查、改寫並診斷 LangChain、LlamaIndex、Ollama 與 XRPL 程式碼，並提供範例與文件檢索。

可以做什麼: 審查並改寫框架程式碼片段，回傳修改片段並標出未處理的危險呼叫點，不執行程式碼
把堆疊追蹤診斷為已棄用 API 並給出修正，查詢某個 API 的套件、匯入與呼叫形式
取得可執行的完整範例檔案、最新語法片段與遷移說明，並對內建框架文件做關鍵字檢索
產生帶型別的 XRPL 交易骨架（從不送出），並列出支援的框架與已知棄用項目
適用情境: 適合在維護或遷移以 LangChain、LlamaIndex、Ollama 或 XRPL 為基礎的程式碼時使用，需要依現行 API 檢查、修補、診斷錯誤或取得可執行的起步範例。框架清單與棄用清單免費，可先試用再決定是否付費。
執行需求: 遠端 Streamable HTTP 端點，未宣告帳號或金鑰。多數工具呼叫按次透過 x402 付費：Base 上 0.001 USDC，或 XRPL 主網 1000 drops XRP / 0.001 RLUSD，需由支援 x402 的用戶端在收到 402 後送出 PAYMENT-SIGNATURE 或 X-PAYMENT 完成結算。文件也提供 npm 本機 stdio 執行方式，本機不收費。

安裝前請注意

正式環境計費已開啟，未付費的工具呼叫會回傳 402，費用按呼叫累積。在 Cursor 中付費需執行代理，以本機 .env 的 EVM_PRIVATE_KEY 簽署 Base USDC，並以 X402_PROXY_MAX_CALLS 限制呼叫次數；該私鑰等同消費錢包，請維持低額度上限。送出的程式碼片段與堆疊追蹤會傳到第三方伺服器。XRPL 工具只產生交易骨架，不會送出或轉移資金。

安裝

在 SourceWeft 中

開啟儀表板中的 Titan Frameworks (LangChain, LlamaIndex, Ollama, XRPL)，將其新增到工作區。
為需要使用其工具的對話啟用該服務。

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。

交給代理程式安裝

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.bebopp187-stack%2Ftitan-frameworks/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。

README

Titan Frameworks

Paid MCP that reviews and rewrites LangChain, LlamaIndex, Ollama, and XRPL code against current APIs — plus runnable examples, import lookup, and tx skeletons that never submit. Live docs are still included.

Live Streamable HTTP: https://titan-frameworks-production.up.railway.app/mcp
Paid with x402: $0.001 USDC on Base or 1000 drops XRP / 0.001 RLUSD on XRPL mainnet.

Agent discovery: llms.txt · Smithery smithery.yaml · MCP Registry server.json

Tools

Tool	Purpose
`review_framework_code`	Lint a snippet for dead APIs before it crashes. Returns hunks, does not execute
`rewrite_framework_code`	Apply conservative catalog rewrites; leftover lists unsafe call sites
`diagnose_framework_error`	Stack-trace → deprecated API → exact fix. Use only when you have an error
`resolve_symbol`	Package, install, import, and call shape for one API name
`fetch_working_example`	Complete runnable file for a goal (agent, rag, payment, …)
`fetch_latest_syntax`	Working snippets and migration notes for one topic. Use when writing a fragment
`search_ai_framework_docs`	Keyword search over local Markdown. Use for concepts/symbols; not stack traces
`draft_xrpl_intent_tx`	Typed XRPL tx skeleton. Never submits or moves funds
`list_supported_frameworks`	Enumerate framework ids, aliases, and catalog topics (free `tools/call`)
`list_known_deprecations`	Full deprecation catalog for one framework or all four

Prompts: migrate_framework_code, diagnose_stack_trace, start_from_example.

Pick one: source about to run → review_framework_code; need a patched file → rewrite_framework_code; stack trace → diagnose_framework_error; know the symbol → resolve_symbol; need a full file → fetch_working_example; topic fragment → fetch_latest_syntax; concept → search_ai_framework_docs; XRPL tx → draft_xrpl_intent_tx; which frameworks → list_supported_frameworks; all deprecations → list_known_deprecations.

json

{  "mcpServers": {    "titan-frameworks": {      "url": "https://titan-frameworks-production.up.railway.app/mcp"    }  }}

{  "mcpServers": {    "titan-frameworks": {      "url": "https://titan-frameworks-production.up.railway.app/mcp"    }  }}

x402-capable clients send PAYMENT-SIGNATURE / X-PAYMENT after a 402. Local stdio (titan-frameworks / npm run dev) does not charge.

To pay production from Cursor, enable titan-frameworks-paid in MCP settings (runs scripts/cursor-x402-proxy.ts, signs Base USDC from EVM_PRIVATE_KEY in .env, cap X402_PROXY_MAX_CALLS default 25). Check the proxy with npx tsx scripts/cursor-x402-proxy.ts --check.

HTTP endpoints

Path	Notes
`GET /health`	liveness + index stats
`GET /llms.txt`	agent discovery
`GET /tools`	tool list + live pricing
`GET /.well-known/x402`	x402scan resource index
`GET /.well-known/x402.json`	full payment requirements + bazaar metadata
`GET /.well-known/mcp/server-card.json`	Smithery static card
`ALL /mcp`	Streamable HTTP MCP. Handshake/`tools/list`/`list_supported_frameworks` free; other `tools/call` paid

Run locally (stdio)

Project config is in .cursor/mcp.json. Seed docs ship in src/data/seed-fallback.json.

Production re-indexes automatically when the live index is older than 24 hours. /admin can still trigger a crawl immediately.

HTTP mode (Vercel / Railway)

Railway uses railway.toml (npm run start). Vercel rewrites to api/index.ts.

x402 micropayments

Production billing is on. Unpaid tools/call on POST https://titan-frameworks-production.up.railway.app/mcp returns 402, except list_supported_frameworks which is free. initialize, ping, and tools/list are free so directories can health-check the connector.

A raw wallet transfer is not an x402 proof. Clients retry /mcp with PAYMENT-SIGNATURE / X-PAYMENT. Local stdio (npm run dev) does not charge.

To reproduce the gate locally: X402_ENABLED=true (mock) plus X402_USDC_LIVE=true / X402_XRPL_LIVE=true for live verify/settle.

Password-gated admin

Production dashboard: https://titan-frameworks-production.up.railway.app/admin

It is not a public stats page. Login is a password checked against ADMIN_SECRET_KEY. Unauthenticated /api/admin/* calls return 401. The old public /admin/api/stats route is gone (404).
