VerifiedSTDIODesktop only

Overview

TradeCanvas's local MCP server; no sign-in required; STDIO.

No AI overview yet: these facts come from the registry entry and the server itself.

Installation

In SourceWeft

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

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

@tradecanvas/mcp

An MCP server for TradeCanvas, so a coding agent looks names up instead of guessing them. It answers from a catalog generated from the library's own code: the same version, the same names.

bash
claude mcp add tradecanvas -- npx -y @tradecanvas/mcp

On Windows outside WSL, npx starts through cmd:

bash
claude mcp add tradecanvas -- cmd /c npx -y @tradecanvas/mcp

In Git Bash, which runs the ! commands of Claude Code on Windows, write cmd //c npx -y @tradecanvas/mcp: Git Bash turns /c into a path.

Cursor, Claude Desktop and most other clients take the same command in their MCP settings (on Windows, "command": "cmd", "args": ["/c", "npx", "-y", "@tradecanvas/mcp"]):

json
{  "mcpServers": {    "tradecanvas": { "command": "npx", "args": ["-y", "@tradecanvas/mcp"] }  }}

Codex adds it with codex mcp add tradecanvas -- npx -y @tradecanvas/mcp, or reads it from ~/.codex/config.toml, where the key is mcp_servers:

toml
[mcp_servers.tradecanvas]command = "npx"args = ["-y", "@tradecanvas/mcp"]

Tools

All of them read only; none touches the network or your files.

ToolWhat it answers
list_indicatorsThe built-in indicators: id, name, and whether it draws over the price or in a pane. Search by words.
get_indicatorOne indicator in full: default params, inputs, the keys of its lines (RSI's is value, not rsi), levels, and code that adds it and reads it.
list_drawing_toolsThe drawing tools: the type that addDrawing and setDrawingTool take, the points each needs, its options.
list_optionsThe options of ChartWidget, Chart or ChartWidgetGrid: name, TypeScript type, doc, allowed values.
list_widget_featuresThe names ChartWidget's features switch takes.
list_style_keysThe chart's style keys and the value each takes, for overrides and applyOverrides.
validate_optionsChecks an options object before it is used: unknown names with the one likely meant, values outside the allowed ones, numbers given as strings, intervals, feature switches, style overrides, languages, and nested options.

A check, for instance:

json
{ "target": "ChartWidget", "options": { "timeFrame": "5m", "chartType": "line", "locale": "ja" } }
text
- timeFrame: Unknown option 'timeFrame' for ChartWidget. Did you mean 'timeframe'?- chartType: Unknown option 'chartType' for ChartWidget. It is a Chart option: on ChartWidget it goes in `chartOptions`.Note: 日本語 ('ja') is not built into the widget: call registerWidgetLocales() from '@tradecanvas/chart/widget/locales' before creating it.

Also

  • The agent skill teaches the API itself, with worked examples: /plugin marketplace add bonguynvan/tradecanvas in Claude Code, or npx skills add bonguynvan/tradecanvas.
  • llms.txt and llms-full.txt hold the docs in one file.

Node 20.19 or later. MIT.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
