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.

| 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.
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.
| 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 |
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.
Railway uses railway.toml (npm run start). Vercel rewrites to api/index.ts.
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.
| Rail | Price | Network | Facilitator |
|---|---|---|---|
| USDC | $0.001 | Base (eip155:8453) | PayAI |
| XRP | 1000 drops (0.001 XRP) | XRPL mainnet (xrpl:0) | T54 |
| RLUSD | 0.001 | XRPL mainnet (xrpl:0) | T54 |
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.

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).
