Overview

AI-generated overview

A hosted, read-only MCP server that lets an assistant query Cedar ARMS railroad data for carriers the signed-in user is authorized to access.

What you can do
List the carriers the signed-in user can access and pass a carrier code to catalog tools. Inspect read-only railcar inventory, equipment history, work orders, bookings, customers, charges, invoices, quotes, and note metadata. Results are paginated and capped at 50 records per call, with sensitive fields minimized before return. No records can be created, updated, moved, or deleted through the connector.
When to use it
Useful when you work with Cedar ARMS and want an AI assistant to look up railcar inventory, equipment history, work orders, bookings, or billing records without leaving the editor. It is read-only, so changes still belong in the ARMS UI.
Requirements
A remote endpoint at mcp.arms.cedarai.com over streamable HTTP. OAuth 2.0 sign-in against Cedar Accounts is required; there is no API key. The signed-in user needs existing ARMS permissions for the carriers they query.
Before you install
Connecting does not grant access to additional carriers or records; each request uses the signed-in user's existing ARMS permissions. Tool results, including some customer and invoice fields, are returned to the assistant, so review the MCP privacy addendum and data handling documentation before connecting. The connector is read-only and cannot modify ARMS records.

Installation

In SourceWeft

  1. Open CedarAI Data Depot in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. 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/io.github.cedarai%2Fcedar-mcp/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

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

cedar-mcp

Cursor plugin for CedarAI Data Depot. The plugin identifier is cedar-mcp.

It connects Cursor to Cedar ARMS through Cedar's remote Model Context Protocol server.

After Cedar login, you can list the carriers you can access and inspect read-only railcar inventory, equipment history, work orders, bookings, customers, charges, invoices, quotes, and note metadata. This connector cannot create, update, move, or delete ARMS records. Mutations belong in the ARMS UI.

Install

  1. Open Cursor Settings → Plugins (or the Cursor Marketplace).
  2. Search for cedar-mcp or CedarAI Data Depot.
  3. Click Install, then complete Cedar sign-in (OAuth).

You can also add the MCP URL by hand under Cursor Settings → MCP:

https://mcp.arms.cedarai.com/mcp

GitHub Copilot / VS Code

After this server is published to the official MCP Registry, search @mcp cedar in the VS Code Extensions view, or add it by hand in .vscode/mcp.json:

json
{  "servers": {    "cedar-mcp": {      "type": "http",      "url": "https://mcp.arms.cedarai.com/mcp"    }  }}

Then use Auth on the server and complete Cedar sign-in. Registry name: io.github.cedarai/cedar-mcp.

MCP

json
{  "mcpServers": {    "cedar-mcp": {      "type": "http",      "url": "https://mcp.arms.cedarai.com/mcp"    }  }}

Auth is OAuth 2.0 against Cedar Accounts. Cursor prompts for Cedar sign-in when the plugin connects. There is no API key.

Pass a railroad road mark as carrier_code (for example TRLD) on catalog tools. Call list_accessible_carriers first if you are not sure which carriers you can access.

Data handling

Each MCP request uses the signed-in user's existing ARMS permissions. Installing this plugin does not grant access to additional carriers or records.

Tool results are returned to Cursor so it can answer the user's request. Cedar minimizes sensitive fields before returning high-volume and free-text results, including street addresses, postal codes, email addresses, telephone numbers, note body text and attachments, invoice audit comments and documents, and selected tender and charge fields. Inventory responses are paginated and capped at 50 records per call.

Review the MCP privacy addendum and MCP data handling documentation before connecting.

Docs

The MCP server is hosted by Cedar. This repository is only the Cursor plugin wrapper (same pattern as Cursor's Google Drive plugin).

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
