Titan Frameworks (LangChain, LlamaIndex, Ollama, XRPL)

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.

Connect a client

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)

cd titan-frameworks
npm install
npm run dev

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

npm run index-docs

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

HTTP mode (Vercel / Railway)

npm run dev:http
# POST http://127.0.0.1:3333/mcp

npm run build
npm start

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.

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.

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).
