Overview

AI-generated overview

Clear Tape is a remote MCP server that gives an assistant free trading calculators, preset trading-system rules, a bilingual glossary and lesson search.

What you can do
Calculate position size, risk/reward, expectancy, ATR stops, drawdown recovery, Kelly risk, trading costs and losing-streak odds from the inputs you supply, each result with units and formula and linked to the matching calculator page. List Clear Tape's eleven preset trading systems or fetch one system's written entry, stop, exit, target and parameters. Look up trading terms in a bilingual English and Simplified Chinese glossary, tolerating misspellings and pinyin. Search Clear Tape's free Learn articles, Academy lessons, strategy pages and calculators by keyword in English or Chinese.
When to use it
Useful when planning or reviewing a trade and you want consistent position sizing, risk/reward or expectancy arithmetic, a written system's rules, or a quick definition or lesson reference. It is a calculation and education aid, not a source of live prices.
Requirements
A remote MCP endpoint over streamable HTTP; no packages, environment variables or headers are declared. No authentication is declared. Network access to the Clear Tape endpoint is needed.
Before you install
The server explicitly provides no market data, so prices, ranges and win rates must come from you and results are only as good as those inputs. Outputs are educational calculations, not investment advice. No credentials are requested, but confirm the endpoint's authentication and data handling before relying on it.

Installation

In SourceWeft

  1. Open Clear Tape in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/ai.cleartape%2Fclear-tape/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
