# quant-research > An MCP server for crypto strategy backtesting whose defining property is that > the SERVER owns the statistical state. The trial count N, dataset splits, > strategy hashes and the cost model live in an append-only ledger, so a caller > cannot understate N to make a result look significant. 39 tools over > streamable HTTP at https://quant-mcp.avasis.ai/mcp. Authentication is a bearer token. An unauthenticated /mcp call returns 401. Every page below is also available as raw Markdown at the .md URL shown. ## Integration - [Agent integration prompt](https://quant.avasis.ai/agents/prompt.txt): A system prompt that maps an AI agent to this server and to these docs. Paste into a system prompt, AGENTS.md, CLAUDE.md or .cursorrules. - [Everything, one file](https://quant.avasis.ai/llms-full.txt): Every page below concatenated. - [Server card](https://quant.avasis.ai/.well-known/mcp/server-card.json): Machine-readable server descriptor with the live tool list. ## Start - [Overview](https://quant.avasis.ai/docs/index.md): A crypto research server that keeps its own trial count, so the statistics it reports cannot be quietly understated. - [Quickstart](https://quant.avasis.ai/docs/quickstart.md): Connect a client, authenticate, and take one idea through the full gauntlet. - [Authentication](https://quant.avasis.ai/docs/authentication.md): Bearer tokens, per-tenant isolation enforced in the database, and what the server does not do. ## Concepts - [The trial ledger](https://quant.avasis.ai/docs/concepts/ledger.md): What counts as a trial, why the count only rises, and why you cannot supply it yourself. - [Splits and the holdout](https://quant.avasis.ai/docs/concepts/splits.md): Immutable ranges, a frozen gap policy, and one evaluation per strategy for the lifetime of that strategy. - [Costs](https://quant.avasis.ai/docs/concepts/costs.md): Fees read the non-promotional tier, and cost is checked before anything else because most ideas die here. - [Effective breadth](https://quant.avasis.ai/docs/concepts/breadth.md): Twenty-two correlated assets are not twenty-two independent tests. M_eff measures how many you actually have. ## Guides - [A worked session](https://quant.avasis.ai/docs/workflow.md): One idea taken from cost check to holdout, including the part where it fails. ## Reference - [Statistics reference](https://quant.avasis.ai/docs/statistics.md): What each test measures, what it does not, and how to read a result that says no. - [Tool reference](https://quant.avasis.ai/docs/tools.md): All 39 tools with parameter schemas. - [Limits and plans](https://quant.avasis.ai/docs/limits.md): Quotas, what happens at the edge of one, and the error shape every failure uses. - [Changelog](https://quant.avasis.ai/docs/changelog.md): What changed, why, and which of it was a correction to something previously wrong.
