安全提示

MCP 服务会接收对话中的工具调用请求，并可能执行外部操作。启用前请先了解该服务能做什么，并只授予它所需的权限。

注册中心已验证此条目所属的 GitHub 账号 bebopp187-stack。这并不表明该账号就是产品方。

SourceWeft 的检查只涵盖条目是否完整、端点是否响应；不审查服务器的代码，也不审查其工具的行为。

概览

AI 生成的概览

付费远程 MCP 服务器，按当前 API 审查、重写并诊断 LangChain、LlamaIndex、Ollama 与 XRPL 代码，并提供示例与文档检索。

可以做什么: 审查并重写框架代码片段，返回修改片段并标出未处理的危险调用点，不执行代码
把堆栈跟踪诊断为已弃用 API 并给出修复，查询某个 API 的包、导入与调用形式
获取可运行的完整示例文件、最新语法片段与迁移说明，并对内置框架文档做关键词检索
生成带类型的 XRPL 交易骨架（从不提交），并列出支持的框架与已知弃用项
适用场景: 适合在维护或迁移基于 LangChain、LlamaIndex、Ollama 或 XRPL 的代码时使用，需要按当前 API 检查、打补丁、诊断报错或拿到可运行的起步示例。框架列表与弃用清单免费，可先试用再决定是否付费。
运行要求: 远程 Streamable HTTP 端点，未声明账号或密钥。多数工具调用按次通过 x402 付费：Base 上 0.001 USDC，或 XRPL 主网 1000 drops XRP / 0.001 RLUSD，需由支持 x402 的客户端在收到 402 后发送 PAYMENT-SIGNATURE 或 X-PAYMENT 完成结算。文档也提供 npm 本地 stdio 运行方式，本地不收费。

安装前请注意

生产环境计费已开启，未付费的工具调用会返回 402，费用按调用累积。在 Cursor 中付费需运行代理，用本地 .env 中的 EVM_PRIVATE_KEY 签署 Base USDC，并以 X402_PROXY_MAX_CALLS 限制调用次数；该私钥等同消费钱包，请保持低额度上限。提交的代码片段与堆栈跟踪会发送到第三方服务器。XRPL 工具只生成交易骨架，不会提交或转移资金。

安装

在 SourceWeft 中

打开控制台中的 Titan Frameworks (LangChain, LlamaIndex, Ollama, XRPL)，将其添加到工作区。
为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。远程服务在工作区中配置后即可从网页运行时运行。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/io.github.bebopp187-stack%2Ftitan-frameworks/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。

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).
