ramp-mcp: A Ramp MCP server

Overview

A Model Context Protocol server for retrieving and analyzing data or running tasks for Ramp using Developer API. In order to get around token and input size limitations, this server implements a simple ETL pipeline + ephemeral sqlite database in memory for analysis by an LLM. All requests are made to demo by default, but can be changed by setting RAMP_ENV=prd. Large datasets may not be processable due to API and/or your MCP client limitations.

Tools

Database tools

Tools that can be used to setup, process, query, and delete an ephemeral database in memory.

process_data
execute_query
clear_table

Fetch tools

Tools that can be used to fetch data directly

get_ramp_categories
get_currencies

Load tools

Loads data to server which the client can fetch. Based on the tools you wish to use, ensure to enable those scopes on your Ramp client and include the scopes when starting the server as a CLI argument.

Tool	Scope
load_transactions	transactions:read
load_reimbursements	reimbursements:read
load_bills	bills:read
load_locations	locations:read
load_departments	departments:read
load_bank_accounts	bank_accounts:read
load_vendors	vendors:read
load_vendor_bank_accounts	vendors:read
load_entities	entities:read
load_spend_limits	limits:read
load_spend_programs	spend_programs:read
load_users	users:read

For large datasets, it is recommended to explicitly prompt Claude not to use REPL and to keep responses concise to avoid timeout or excessive token usage.

Setup

Ramp Setup

Create a new client from the Ramp developer page (Profile on top right > Developer > Create app)
Grant the scopes you wish (based on tools) to the client and enable client credentials (Click on App > Grant Types / Scopes)
Include the client ID and secret in the config file as well as the scopes you wish to use

Local Setup

Clone this Github repo via git clone git@github.com:ramp/ramp-mcp.git or equivalent
Install uv

Usage

Run the MCP server from your CLI with:

RAMP_CLIENT_ID=... RAMP_CLIENT_SECRET=... RAMP_ENV=<demo|prd> uv run ramp-mcp -s <COMMA-SEPARATED-SCOPES>

Configuration

        "--directory",
        "/<ABSOLUTE-PATH-TO>/ramp-mcp", // make sure to update this path
        "run",
        "ramp-mcp",
        "-s",
        "transactions:read,reimbursements:read"
      ],
      "env": {
        "RAMP_CLIENT_ID": "<CLIENT_ID>",
        "RAMP_CLIENT_SECRET": "<CLIENT_SECRET>",
