Honest A-F grades for trading strategies, backtested on real out-of-sample data. No hype.

ai.tessen/grader (MCP Server)

The ai.tessen/grader MCP server provides Honest A-F grades for trading strategies. It evaluates strategies that have been backtested on real out-of-sample data, focusing on producing letter-grade assessments without promotional framing. The server is identified by the slug ai-tessen-grader.

🛠️ Key Features

Generates A-F grades for trading strategies
Uses backtested results based on real out-of-sample data
Designed to avoid “hype” in grading descriptions

🚀 Use Cases

Grade trading strategies after out-of-sample backtesting
Compare strategies using a consistent letter-grade scale

⚡ Developer Benefits

Integrates an automated grading workflow into MCP-based tooling
Standardizes evaluation outputs as A-F assessments

⚠️ Limitations

Only described as grading based on real out-of-sample data; other evaluation dimensions are not specified

Captured live from the server via tools/list.

get_agentspec_reference

The exact AgentSpec JSON schema + indicator list + grade-report shape. Read this BEFORE constructing a spec for grade_strategy. Free, no key needed.

Parameters

No parameters.

Raw schema

{
  "type": "object",
  "properties": {},
  "additionalProperties": false
}

grade_strategy

Backtest + grade an AgentSpec on 6 years of real data: 60/40 chronological train/OOS split, fees modeled, five hard gates (positive OOS expectancy, clears cost hurdle, robust across assets, survivable drawdown, not overfit). Returns the full grade report and a permanent public verify URL. Requires an API key (free at tessen.ai/studio/keys). Call get_agentspec_reference first for the schema.

Parameters1

agentSpec

object

required

AgentSpec per get_agentspec_reference

Raw schema

{
  "type": "object",
  "properties": {
    "agentSpec": {
      "type": "object",
      "description": "AgentSpec per get_agentspec_reference"
    }
  },
  "required": [
    "agentSpec"
  ]
}

grade_trade_record

Grade the caller's OWN trade history (>=30 trades) instead of a backtest — chronologically 60/40 split, same gates. Marked 'Checked' not 'Verified' since the data is self-supplied. Requires an API key.

risk_per_trade_pct	number	optional
