Barzel FinOps Atlas: Free AI Agent and Composio Cost Calculator MCP

Barzel FinOps Atlas is a free AI-agent cost calculator and governed finance-control MCP server for AI platform teams, engineering FinOps, CFOs, controllers, auditors, risk analysts, and compliance leaders.

Start with the free calculator to estimate Composio and tool-call cost, compare actual versus projected AI-agent spend, calculate cost per agent/workflow/customer/successful outcome, enforce budgets, compare providers, detect anomalies, and download a savings report. Atlas also assesses month-end close, traces financial evidence, detects payment risks, forecasts cash, orchestrates workflows, and prepares SOX, SOC 2, internal audit, and external audit evidence.

What a marketplace subscription includes: access to the labeled synthetic sandbox and the MCP control-plane surface for evaluation, agent integration testing, workflow design, and implementation planning. It does not include live customer-system connections or production financial processing. Production deployments require a separate written implementation agreement and customer-authorized data plane.

Activation and credentials: sandbox subscriptions activate automatically after checkout. The server uses MCPize per_user credentials, so a production customer can provide a customer-scoped access token without sharing one finance credential across all buyers. The credential is optional in sandbox and mandatory for live customer-data requests.

Free AI Agent Cost Calculator

calculate_agent_costs is one consolidated tool rather than a bulky collection of cost endpoints. Use it for:

• Composio, MCP, API, trigger, and generic tool-call cost estimates
• model input/output tokens, reasoning tokens, cache reads/writes, sandboxes, storage, network egress, and human approvals
• actual versus projected agent cost
• cost by tenant, customer, user, team, agent, workflow, MCP server, tool, model, provider, and business outcome
• true cost per resolved ticket, completed reconciliation, qualified lead, approved invoice, or successful workflow
• failed-attempt and retry cost
• daily, monthly, workflow, action, and dimension-level budget alerts and hard spend limits
• Barzel Vault allow, warn, approval, and block decisions before governed spend
• provider routing by price, quality, latency, risk, and success rate
• agent loops, retry storms, runaway reasoning, duplicate workflows, and context growth
• semantic-cache candidates and savings
• forecasts, anomalies, pricing-change impact, and cost-per-outcome deterioration
• Composio, Barzel-based, and self-hosted vendor scenarios using caller-supplied rates
• vendor invoice reconciliation and audit evidence
• downloadable Markdown savings report and CSV allocation report

Atlas labels fallback rates as illustrative. Supply a dated price book, quote, contract, invoice, or recorded actual cost before making purchasing or budgeting decisions.

Cost-Risk-Outcome Graph

Atlas connects spending -> action -> policy -> risk -> result -> business value. This makes cost explainable in operational and financial terms instead of stopping at a token or usage dashboard.

What Barzel FinOps Atlas Does

Atlas connects financial transactions, invoices, purchase orders, payments, journal entries, contracts, approvals, reconciliations, policies, and controls through a financial evidence graph.

That evidence graph helps finance teams answer:

• Are we ready to close the month, quarter, or year?
• Which blockers are most likely to delay the financial close?
• Why should an auditor trust this invoice, payment, journal entry, or balance?
• Which transactions are missing approvals, reconciliations, or control support?
• Are there possible duplicate payments, split invoices, or approval bypasses?
• Which vendors, customers, accounts, or controls create the highest risk?
• What evidence is missing for a SOX, SOC 2, internal audit, or external audit request?
• Why is cash below forecast, and what should the CFO do next?
• Which finance workflows are blocked, overdue, or waiting for approval?

Month-End Close Readiness

Atlas acts as an AI month-end close assistant. It can score close readiness, identify close blockers, analyze unreconciled items, find missing journal support, create close checklists, summarize owner actions, and estimate completion risk.

Use it for month-end close, quarter-end close, year-end close, bank reconciliation review, journal support review, close status reporting, and controller action queues.

Audit Evidence and Audit Defense

Atlas traces financial evidence from source event to document, approval, reconciliation, control, and audit framework. It can verify evidence chains, detect missing support, map evidence to controls, assemble audit packet sections, draft auditor responses, and disclose gaps honestly.

Supported audit and compliance workflows include:

• SOX financial controls
• SOC 2 finance-related controls
• ISO 27001 evidence involving financial systems
• internal audit
• external audit
• PBC request preparation
• local tax compliance support
• board and audit committee review
• vendor due diligence

Duplicate Payments and Accounts Payable Controls

Atlas helps accounts payable and finance controls teams investigate duplicate-payment signals, split invoices, approval bypasses, vendor integrity concerns, unusual payment timing, and missing purchase-order or approval evidence.

It can combine amount, vendor, invoice reference, timing, approval, evidence confidence, tax exposure, and anomaly signals into a structured transaction-risk assessment.

Accounts Receivable and Revenue Risk

Atlas supports AR leakage analysis, overdue receivables, collection risk, unusual discounts, credit memo concerns, revenue recognition evidence, and customer-level cash exposure.

It can connect customer contracts, invoices, revenue events, approvals, reconciliations, controls, and cash receipts into an evidence-backed lineage.

Cash Forecasting and Cash Variance

Atlas forecasts short-term cash position using receivables, payables, payroll, tax, expected inflows, expected outflows, payment timing, and collection timing.

It can explain why cash differs from forecast, budget, plan, or the prior period and identify near-term liquidity pressure for CFO and treasury discussions.

Finance Workflow Automation

Atlas creates and monitors governed workflows for:

• invoice-to-pay
• order-to-cash
• financial close
• audit request defense
• vendor onboarding
• bank reconciliation
• revenue recognition
• tax preparation
• expense reimbursement
• payroll review
• procurement approval

Workflow outputs include state, owner, SLA, blockers, evidence requirements, pending approvals, exceptions, and recommended next actions.

CFO, Controller, Board, and Audit Committee Reporting

Atlas turns evidence-backed findings into CFO summaries, controller memos, close status updates, board finance packs, cash-risk summaries, variance explanations, audit committee reports, and compliance narratives.

Every high-stakes workflow is designed to preserve evidence citations, gap disclosure, finance-owner review, and approval requirements.

Why Barzel FinOps Atlas Is Different

Barzel FinOps Atlas is not a stock-price, crypto-price, trading, or generic market-data MCP server. It focuses on internal finance operations, financial controls, close readiness, evidence lineage, risk analytics, and audit defense.

It is also more than a single-system accounting connector. Atlas is designed to reason across accounting, ERP, banking, payment, CRM, document, tax, and workflow systems while preserving transaction-to-control lineage.

Cloud billing tools explain infrastructure charges by account, service, resource, or tag. Atlas complements them by attributing model, MCP, tool, orchestration, infrastructure, and human-review spend to the agent action and successful business outcome, including failed attempts and retries. It then connects that cost to governing policy, risk, result, business value, vendor invoice, and evidence.

The product's dual-graph model is intentionally specific: the Cost-Risk-Outcome Graph answers whether an agent action was economical and policy-compliant, while the financial evidence graph answers whether the resulting finance decision is supportable in close, control testing, and audit defense.

The server intentionally remains one governed product. Its discovery layer routes requests across a compressed surface of 30 tools, 21 resources, and 16 prompts. The whole agent-cost control plane is one tool, preserving context without splitting Atlas into multiple servers.

Supported Finance Systems

Atlas is designed for implementation around QuickBooks, Xero, NetSuite, Sage, SAP, Oracle, Stripe, Salesforce, HubSpot, Google Drive, SharePoint, Microsoft 365, and customer-specific accounting, ERP, banking, CRM, storage, tax, and workflow systems.

A listed system is integration-compatible positioning, not a claim that a live connector is enabled in the public sandbox.

Customer-Safe Operation

The public MCPize deployment is a synthetic sandbox. Finance records and scores are visibly labeled and are never represented as customer facts.

Production mode is fail-closed. It requires authenticated tenant identity, recognized finance roles, tenant allowlisting, approval gates, and a customer-authorized finance data plane. It never silently falls back to sample data.

Marketplace usage plans cover the public sandbox. Customer-specific production implementation, connectors, data processing, support commitments, and service levels are separately scoped.

Examples and Agent Discovery

Every tool, resource, and prompt includes a concrete request and expected output. MCPize exposes the public hosted manifest at /.well-known/mcp/barzel-finops-atlas-mcp.json. Subscribed/API-authenticated agents and direct-hosted deployments can inspect the complete runtime-derived catalog at /catalog.json, compact examples at /examples.json, concise product context at /llms.txt, and full capability context at /llms-full.txt.

Start with list_capabilities when exploring the product or search_capabilities for intent-based routing. Example questions include:

• Assess month-end close readiness and rank the blockers most likely to delay completion.
• Trace an invoice through purchase order, approval, payment, bank evidence, and control checks.
• Find possible duplicate payments, split invoices, and approval bypasses.
• Assemble a SOX evidence packet and disclose missing support.
• Explain cash variance and identify near-term liquidity risk.
• Prepare an evidence-backed board finance summary.
• Calculate true Composio and AI-agent cost, including failures and retries, then download a savings report.
• Check whether the next agent action should be allowed, warned, approved, or blocked by budget policy.
• Compare provider routes and reserve premium models for high-risk work.

Five-Minute Getting Started

1. Call search_capabilities with the buyer's finance or Agent FinOps question. It returns matching tools with permissions, credentials, errors, and examples.
2. Call calculate_agent_costs for the free Composio and tool-call estimate, including failures, retries, cost per outcome, budget impact, and provider savings.
3. Call trace_financial_evidence to inspect transaction-to-document, approval, payment, reconciliation, and control lineage.
4. Call assess_close_readiness or audit_defense_action for an evidence-backed close or audit workflow.
5. Keep the marketplace sandbox labeled and synthetic. Connect live finance data only through the separately authorized production data plane and per-user customer token.

Reliability and Health

The deployment exposes public /health for process liveness and app-level /ready for dependency readiness. Production fails closed until authentication, tenant policy, customer data plane, and audit sink checks all pass. Health aliases and automated live validation support common hosting and monitoring systems in direct-hosted deployments, while MCPize protects subscribed runtime routes through its gateway.

Frequently Asked Questions

Is it one MCP server?

Yes. Atlas deliberately preserves agent-cost and finance context in one server while compressing the public surface to 31 high-signal tools, 21 resources, and 16 prompts.

Is the agent cost calculator free?

Yes. The Free Sandbox plan includes calculator calls using caller-supplied usage and rates. Production telemetry connections, durable ledgers, Vault enforcement, and customer data processing require a separately configured deployment.

Does the calculator include failed attempts and retries?

Yes. They remain in the cost numerator, so cost per successful outcome reflects the true cost of producing the result.

Does checkout grant access to live customer finance data?

No. Checkout automatically activates only the labeled synthetic sandbox. Live data requires customer authorization, a separate production implementation, and a per-user customer access token.

Are credentials shared across customers?

No. MCPize is configured in per_user mode. Production data-plane credentials are customer scoped and are not embedded in source code, tool arguments, outputs, or audit events.

How does Atlas differ from finance market-data MCP servers?

Atlas focuses on internal finance operations, evidence lineage, controls, close readiness, risk analytics, governed workflows, and audit defense rather than market prices or trading.
