MCP plugin + REST API for financial modeling

Give your Claude a new superpower.

Build a full financial model without leaving Claude. The Layerz MCP plugin lets your agent spin up a structured model from a prompt, read values mid-conversation, edit formulas and scenarios, and export a clean .xlsx — your prompts, your tokens, your data.

The wall you keep hitting

Claude is powerful. The layer underneath isn’t.

You use Claude. You build financial analyses in chat. The next session, you start over.

You paste numbers, re-explain assumptions, rebuild context. Google Sheets can hold data. Airtable can organize records. PowerQuery can transform tables. None of them give your agent a structure it can navigate — typed variables, formula logic, timelines.

Layerz stores the structure, not just the numbers.

What the plugin gives your agent

Four primitives, no glue code.

  • Read model structureVariable names, types, formulas, dependencies — exposed natively to your agent.

  • Query computed valuesRevenue, EBITDA, cash flow, any output at any period — already computed by the engine.

  • Update assumptionsChange a growth rate or headcount line, and every dependent output recomputes automatically.

  • Export ExcelTrigger a clean .xlsx from your agent session. Your colleagues open a standard file.

Your agent navigates the model. You review the outputs. The structure persists across sessions.

What you can build

The shape of a Layerz workflow.

Auto-populated templates

A budget or deal model your Claude agent fills from a prompt — structured outputs, not a raw table. Change one assumption, all outputs update. Queryable via API.

Live dashboards

A Claude artifact, a Google Data Studio report, or an Excel file that pulls live values from your Layerz model — revenue, EBITDA, unit economics, scenario outputs. No manual refresh.

Persistent small models

Unit economics, capacity planning, sensitivity analysis. Define the structure once, iterate across Claude sessions without losing prior states or re-explaining the logic.

Multi-scenario outputs

Run base / upside / downside across a shared model structure. Export any scenario to clean .xlsx — your colleagues get a standard file, they never see the backend.

How it fits your stack

Built for financial logic, not generic data.

Layerz combines the dynamic calculations of a spreadsheet with the structure of a data model — built specifically for financial logic your agent can navigate without explanation.

How to connect

One command. Your agent connects to your model.

1

Add the Layerz MCP server

Add to your Claude configuration (Desktop, Code, or any MCP-compatible client).

2

Authenticate

Sign in with OAuth — no API key copy-paste, no manual token rotation.

3

Your agent calls Layerz tools directly

layerz_read, layerz_patch, layerz_get_model, layerz_build_from_blueprint, and more — invoked in conversation.

claude mcp add -t http layerz https://app.layerz.cc/mcp

Run it, then `claude /mcp` to authenticate via OAuth.

MCP clients

Works with any MCP-compatible agent.

BYOA — Bring your own agent

Your prompts. Your tokens. Your data.

Layerz does not capture your Claude session. Connect your own Claude Max subscription or API key. Your prompts, your data, your environment.

Layerz is the structured backend, not the middleware.

Supported: Claude (MCP), any MCP-compatible agent, Claude Code, OpenAI Codex.

20+ finance professionals are using Layerz to build what their colleagues can’t explain — dashboards that update live, models their agents navigate without re-explanation, analyses that run in minutes instead of days. They’re not waiting for their company to approve a tool.
