What is the Abacus MCP Server?
The Abacus MCP Server is a Model Context Protocol connector that exposes your Abacus expenses, expense reports, and approvals to AI agents — so a model like Claude or ChatGPT can read and act on them safely, instead of you copying data across by hand.
Abacus does its job well — but everything around it is still manual: entering expenses, chasing approvals, checking policy, and closing out the month. The Model Context Protocol (MCP) is an open standard that lets an AI agent call an app's actions directly. Flozic's Abacus MCP Server wires those expense actions into any MCP-compatible agent.
On Flozic, the Abacus MCP Server gives you:
- Abacus over OAuth — read and write expenses, expense reports, and approvals through approved endpoints, no raw keys to manage
- MCP tools for any agent — Claude, ChatGPT, and Cursor call the same Abacus tools to submit, categorize, route, and summarize
- AI reasoning inside the flow — the agent decides which Abacus action to take, then chains it across 1,000+ other apps, no code
Connect Abacus to your AI agent in 3 steps
No custom API code, no developer. Authorize Abacus, enable the MCP server, and point your agent at Flozic — live in under 15 minutes.

Turn on the Abacus MCP Server in Flozic. It exposes expense, report, and approval tools over the Model Context Protocol, ready for any agent.
Point your agent & run
Connect Claude, ChatGPT, or Cursor to the Flozic MCP endpoint. Your agent can now act in Abacus in real time, with every action logged and replayable.
What AI agents can do with Abacus via MCP
The Abacus MCP Server exposes expenses, expense reports, and approvals as tools. An agent reads context, reasons, and acts — covering submission, categorization, approval routing, and spend summaries end to end.
Submit & categorize
Ask the agent to submit a receipt, categorize an expense, or search past expenses in Abacus — it pulls the record and acts through the MCP tools.
agent: read new receipt
→ categorize expense in abacus
→ leave ready to submit
Route & manage approvals
The agent can route, approve, or flag expense reports and catch anything that breaks policy in Abacus — with the right approver and threshold.
agent: check expense report
→ route to approver in abacus
→ flag policy issue
Reason, then route
The agent decides which Abacus action to take, then chains the result across 1,000+ apps — alert Slack, log a CRM record, or update a sheet.
new expense → agent review
→ classify + decide
→ alert Slack

Design Abacus agent flows on a visual canvas
Put a Abacus trigger on the left, an AI agent step in the middle, and your destination apps on the right. Watch real-time test runs show exactly what the agent did.
A canvas built for agents, not just rows
An MCP-driven workflow is more than "copy a record." Flozic treats the expense or report as the trigger: Abacus fires it, an AI agent reasons over it, and the right apps act — with logic branches on any field.
- Abacus expense, report, and approval tools over MCP
- AI agent reads context and decides the action (Claude, ChatGPT, Gemini)
- Map any Abacus field into the workflow and any result back
- Branch on any field, value, or status
- Real-time test runs with per-step latency

A team gave their AI agent Abacus and stopped drowning in expense reports
How a team automated Abacus end to end
Every expense report used to be handled by hand — entered, checked against policy, routed for approval, and logged into the books. They connected the Abacus MCP Server: an AI agent now categorizes each expense, flags policy issues, routes the report to the right approver, and posts a summary to Slack. The manual work is gone and the team got hours back every week.
Enterprise-grade security by default
Scoped OAuth, SOC 2 Type II audited, GDPR + CCPA compliant, ISO 27001 aligned. Abacus connects over scoped access, your data is never used to train any LLM, and every agent action is logged.

Written by founders who ship AI agents & MCP integrations in production
"An app like Abacus is only as good as what your AI agent can do with it. We built the Flozic MCP servers so a team can hand Claude or ChatGPT the tools to run their expense reports and approvals — safely, and in an afternoon instead of a quarter."
Abhinav founded Appy Pie LLP in 2016 after a Computer Science degree from the University of Westminster. Over the last decade his teams have shipped no-code platforms used by 10M+ users — and today lead Flozic's AI workflow platform. He has worked with operations, marketing, and sales teams to ship Abacus MCP integrations across the stack.
