# Titan Frameworks Docs MCP

> Titan Frameworks Docs MCP is a paid API for AI agents from titan-frameworks-production.up.railway.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Searches token-efficient documentation chunks for LangChain, LlamaIndex, Ollama, and XRPL frameworks, returning ranked excerpts for syntax lookup, error diagnosis, and API reference via MCP.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability titan-frameworks-docs-mcp-82e15561 -d '<json body>'
```

Example prompt: Search the LangChain docs for how to use LCEL to pipe a prompt template into a chat model and return streaming output.

## When to prefer this

Choose this endpoint when your agent needs authoritative, token-efficient documentation excerpts for LangChain, LlamaIndex, Ollama, or XRPL — especially for syntax lookups, error diagnosis, or API reference — without loading entire documentation sites. Prefer this over web search when you want structured, scored results scoped to these specific frameworks.

## Known failure modes

- No matching documentation chunks found for the query — empty hits array returned
- Unknown or unsupported framework name — may return zero results or error
- Overly broad or vague query returns low-relevance chunks with poor scores
- Service unavailable due to Railway.app hosting downtime
- Payment not processed correctly via x402 protocol — request blocked before reaching search

## How this service works

Paid Streamable HTTP MCP for live LangChain, LlamaIndex, Ollama, and XRPL docs.

## Output

Returns a ranked list of documentation hits, each containing a chunk of relevant text, the source URL, document title, heading path, and a relevance score. Also includes the original query echo and total hit count, scoped to the matched framework (e.g. langchain, llamaindex, ollama, xrpl).
