Talk to your XP Investimentos portfolio through Claude — 100% local, read-only, zero scraping.

What is this?

portfolio-mcp is a Model Context Protocol server that exposes your XP Investimentos portfolio to Claude Desktop (or any MCP-compatible client). You feed it the official PDF/CSV exports XP already gives you — the server parses them, normalizes everything into a local SQLite database, and answers questions through MCP tools.

• 🔒 Local-first — data lives in ~/.xp-mcp/data.db. Core tools make zero outbound HTTP calls; advisor tools (v0.4+) are opt-in.
• 📵 No credentials, no scraping — you control what goes in (PDF/CSV exports).
• 👁 Read-only by design — no tool can place orders or modify anything at XP.
• 🧱 Stdio transport — Claude spawns the process; nothing listens on a port.

Built for personal use, but the architecture works for any custodian that lets you export reports (Rico, NuInvest, Inter, Avenue, ...). PRs welcome.

---

Why does this exist?

Custodian apps are great at "show me what I have" but terrible at:

• "Compare my current allocation against my target portfolio."
• "Which of my CDBs mature in the next 12 months?"
• "What's my real yield-to-maturity weighted by position size?"
• "How concentrated am I in a single issuer's FGC limit?"

MCP lets you bolt that intelligence onto Claude without giving the LLM provider your credentials, sending your positions to a third-party SaaS, or trusting browser-scraping that breaks every quarter.

Quick Start

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "portfolio": {
      "command": "npx",
      "args": ["-y", "portfolio-mcp"]
    }
  }
}

Config file location:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

Restart Claude Desktop. Done.

See Development below for clone + build instructions if you want to hack on the server.

How to export from XP

XP has no single "export everything" button. Try in this order:

1. XPerformance PDF (recommended) — Investimentos → XPerformance → ⬇ PDF. The richest single-file snapshot.
2. Portal XP web — Investimentos → Posição Consolidada → Exportar CSV
3. Hub XP / Assessor Digital — Meus Investimentos → Posição → Exportar
4. Notas de corretagem (PDF) — Conta → Documentos → Notas de Corretagem (phase 2)
5. Extrato de movimentação — Conta → Extrato → filtrar período → Exportar

The CSV parser auto-detects ;, ,, \t, | delimiters and fuzzy-matches common XP column names (Quantidade, Qtd, Preço médio, Valor aplicado, ...). If a column is missed, extend HEADER_ALIASES in src/parsers/csv-extract.ts.

Configuring your target allocation

calculate_allocation_drift reads ~/.xp-mcp/allocation.json. A starter file is included at examples/allocation.example.json. Copy it once and edit the percentages:

mkdir -p ~/.xp-mcp
cp examples/allocation.example.json ~/.xp-mcp/allocation.json

The seven valid keys are TESOURO, RENDA_FIXA_PRIVADA, FII, ETF, ACAO, FUNDO, CRIPTO. Values must sum to 1.00 (±0.001). tolerance_pp is optional — when set, drifts within the band are reported as "ok" with no action.

---

Try it without Claude

The server speaks JSON-RPC 2.0 over stdio. Smoke test from any terminal:

node dist/index.js <<'EOF'
{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"smoke","version":"0.0.0"}}}
{"jsonrpc":"2.0","method":"notifications/initialized"}
{"jsonrpc":"2.0","id":2,"method":"tools/list"}
EOF

You should see the server announce itself and list the registered tools.

---

Advisor (opt-in)

v0.4 adds four MCP tools that turn portfolio-mcp into an investment-analysis advisor. These tools are opt-in: they only make outbound HTTP calls when the user has set outbound_enabled: true in their profile and accepted the disclaimer.

Configure your profile

The profile lives at ~/.xp-mcp/advisor-profile.json. Create or update it with set_advisor_profile:

{
  "risk_tolerance": 6,
  "horizon_years": 15,
  "objective": "balanced",
  "monthly_income_target_brl": 3000,
  "excluded_classes": ["FUNDO"],
  "excluded_tickers": ["XYZW3"],
  "notes": "evitar tabaco, prefiro logística e shoppings",
  "outbound_enabled": true,
  "brapi_token": "..."
}

When you flip outbound_enabled to true, the tool requires accept_disclaimer: true in the same call and stamps accepted_disclaimer_at on the saved profile.

Disclaimer

Análise educacional baseada em dados públicos. Não constitui recomendação de investimento. Decisões financeiras são de sua responsabilidade.

The disclaimer is also returned in warnings[0] of every advisor tool that ranks or suggests assets.

Source: brapi.dev

v0.4 uses brapi.dev as the sole market-data source. Anonymous calls work for personal use; if you hit rate limits, set brapi_token in the profile. Quotes are cached for 60 minutes, fundamentals for 24 hours, universe lists for 7 days. Override per call via cache_ttl_minutes.

Example flow

1. set_advisor_profile — saves the profile, enables outbound
2. get_market_data { tickers: ["BBAS3","MXRF11"] } — quotes
3. screen_assets { asset_class: "FII", criteria: { sort_by: "dividend_yield", order: "desc", filters: { min_dividend_yield_pct: 8 }, limit: 10 } }

Data model

imports        every parse attempt with row counts, timestamps, source path
positions      one row per (asset_class, external_id); upserted on re-import
transactions   buys/sells from broker notes (phase 2)
dividends      income / proventos (phase 2)

All monetary values are stored as INTEGER cents. Float math + currency is a well-known source of off-by-a-cent bugs; integers make every aggregation exact.

The UNIQUE (asset_class, external_id) constraint + ON CONFLICT DO UPDATE makes re-importing the same file idempotent — no duplicates, no manual deduping.

---

Design decisions worth calling out

• Wide positions table with nullable per-class columns. A table-per-asset-class would be cleaner in theory but adds JOINs for every read, and the column set is small. The wide table fits the access pattern (Claude almost always wants "all positions, maybe filtered by class").
• Stdio over HTTP. Claude Desktop spawns the process directly. Zero ports listening, no auth surface, no CORS to misconfigure. Trade-off: no remote clients without a wrapper.
• stderr-only logging. stdout is the JSON-RPC wire. One stray console.log silently corrupts every response. All logs go to stderr, where Claude Desktop captures them into ~/Library/Logs/Claude/mcp-server-xp.log.
• No price fetching in MVP. Adding it means a network dependency and a rate-limit problem. When it lands (phase 2), it'll be behind an opt-in env var with a clearly-documented data source.

---

Privacy

• The SQLite file (~/.xp-mcp/data.db) is the only place your position data lives. .gitignore blocks *.db, *.sqlite, and data/ from ever being committed.
• The server makes no outbound HTTP calls for the core import/inspection tools (import_xperformance_pdf, import_extract_csv, get_positions, calculate_allocation_drift). No telemetry. No analytics.
• The v0.4 advisor tools (get_market_data, screen_assets) call brapi.dev only when outbound_enabled: true in ~/.xp-mcp/advisor-profile.json and the user has accepted the disclaimer. Disabled by default.

---

Roadmap

• [x] CSV parser for Posição Consolidada / Extrato
• [x] get_positions with class filter, P&L when invested-value is known
• [ ] import_nota_corretagem (broker-note PDF → transactions)
• [ ] CSV parser for proventos export
• [x] calculate_allocation_drift against ~/.xp-mcp/allocation.json
• [x] v0.3 — npm publish + Smithery + awesome-mcp PR
• [x] v0.4 — Investment advisor foundations: set_advisor_profile, get_advisor_profile, get_market_data, screen_assets (brapi.dev, SQLite cache)
• [x] v0.5 — Portfolio summary + reconciliation gap: get_portfolio_summary (aggregate stats, declared-vs-computed gap)
• [x] v0.6 — Bank extract import + cash flows: import_bank_extract_pdf (XP Conta Digital Extrato → cash_flows table, schema v3), get_cash_flows (filterable query with aggregate totals)
• [x] v0.7 — Suggest Buys: suggest_buys (composes profile + drift + screening into deterministic BUY suggestions per underweight class; non-screenable classes surface in skipped_classes)
• [x] v0.8 — cash_flow_summary in get_portfolio_summary: YTD + rolling 12m aporte/resgate aggregates in the panorama output (no new tool, additive field).
• [x] v0.9 — calculate_twr + calculate_mwr: time-weighted and money-weighted returns over XPerformance imports + cash_flows (Modified Dietz chained + bisection IRR; no schema change; tools MCP 12 → 14).
• [x] v0.10 — get_crypto_quote: spot crypto quotes in BRL via Mercado Bitcoin (CryptoQuoteSource interface + MercadoBitcoinSource impl; per-ticker partial failure; 15-min cache; outbound-gated; quote-only; tools MCP 14 → 15).
• [x] v0.11 — multi-source crypto: get_crypto_quote now falls back across Mercado Bitcoin → Foxbit → Binance (MultiSourceCryptoQuoteSource chain), with Binance USDT quotes converted to BRL via the MB USDT/BRL rate; widens altcoin coverage (internal only — still 15 tools).
• [x] v0.12 — crypto as a tracked asset_class: set_crypto_position (manual entry, CRIPTO added to ASSET_CLASSES, snapshot valuation via the v0.11 multi-source chain, no cost basis; flows into summary/drift/suggest_buys with no service change; tools MCP 15 → 16).
• [ ] Adapters for other Brazilian brokers (Rico, NuInvest, Inter, Avenue)
• [ ] Open Finance Brasil investment module when the standard matures

Changelog

v0.12.0 — crypto as a tracked asset_class (2026-05-25)

• New tool set_crypto_position: manual entry that makes crypto a first-class tracked asset_class (CRIPTO). Fetches a live quote via the v0.11 multi-source chain (Mercado Bitcoin → Foxbit → Binance) and upserts a positions row with a snapshot market value (quantity × current price). Outbound-gated.
• quantity: 0 removes the holding (idempotent single tool). Re-running the tool refreshes the snapshot in place.
• Snapshot valuation, no cost basis / P&L: manual entry records quantity + current market value only (avg_price_cents/ invested_cents stay null), so crypto shows market value but no profit/loss — mirroring how XP positions are snapshots from the last import.
• Crypto flows into get_portfolio_summary and calculate_allocation_drift automatically — both already aggregate by asset_class, so no service change was needed. A crypto holding with no target key shows as over-target vs 0% in drift; in suggest_buys it lands in skipped_classes (CRIPTO is non-screenable).
• Additive: "CRIPTO" added to ASSET_CLASSES, no DDL change, no SCHEMA_VERSION bump, no new dependency. Tools MCP: 15 → 16.

v0.11.0 — multi-source crypto (2026-05-25)

• get_crypto_quote now defaults to a multi-source fallback chain (MultiSourceCryptoQuoteSource): Mercado Bitcoin → Foxbit → Binance. Tries each in order, falling through on TickerNotFoundError or a recoverable error, returning the first successful quote.
• New FoxbitSource (BRL-native) widens Brazilian coverage; new BinanceSource (USDT-native) covers the altcoin long tail, converting every monetary field to BRL via a USDT/BRL rate from the already-integrated Mercado Bitcoin /USDT/ticker/ endpoint (MbUsdBrlRate) — no new external FX dependency.
• CryptoQuote gains additive optional fields price_usd and fx_rate_brl_per_usd for conversion transparency (BRL-native sources leave them undefined).
• The cache row records the source that actually answered (e.g. binance), not the strategy name multi; top-level result source is "multi" while each quote.source keeps the real origin.
• Internal only — get_crypto_quote is still one tool. Tools MCP: 15.

v0.10.0 — get_crypto_quote (2026-05-24)

• New tool get_crypto_quote: spot crypto quotes in BRL via Mercado Bitcoin's public ticker API. 1-20 symbols per call, per-ticker partial failure, 15-minute cache, outbound-gated.
• New CryptoQuoteSource interface + MercadoBitcoinSource impl — slim interface (no equity fundamentals/universe), leaves the door open for Binance/Foxbit later.
• MarketDataCache.put gains an optional source param (default brapi.dev — no behaviour change).
• Crypto is NOT yet a tracked asset_class — quote-only foundation. Scope B (positions, schema migration, summary/drift integration) deferred to a future TODO.
• Tools MCP: 14 → 15.

v0.9.0 — calculate_twr + calculate_mwr (2026-05-24)

• New tool calculate_twr: time-weighted return (Modified Dietz between consecutive XPerformance snapshots, geometric chain across sub-periods). GIPS-compliant for portfolios without daily NAV.
• New tool calculate_mwr: money-weighted return (IRR via bisection on signed cash flows + synthetic initial/terminal NAV). Reports converged: false cleanly when no sign change in [-99%, 1000%].
• New repo function listValuationSnapshots reads XPerformance imports as the NAV history — no schema change.
• New pure service services/returns.ts with hand-computable test references (CFA Modified Dietz example + 1Y 10% MWR case).
• Quality warnings: sparse history, large cash flows, tiny period, MWR non-convergence, stale tail.
• Tools MCP: 12 → 14.

v0.8.0 — cash_flow_summary in get_portfolio_summary (2026-05-24)

• Additive field on get_portfolio_summary: cash_flow_summary block with YTD + rolling 12-month aporte/resgate aggregates.
• New repo function listCashFlowsSince (unbounded date-bounded query) in src/storage/cash-flows-repo.ts.
• New pure service computeCashFlowSummary in src/services/cash-flow-summary.ts — YTD + rolling 12m aggregates over CashFlowRow[], no DB access. Averages divide by months_with_data (not 12) so short histories are not penalised.
• get_portfolio_summary warns when no cash flows have been imported yet (cash_flow_summary: null).
• 12 tools total (unchanged). No schema migration. No new MCP tool — additive field on existing tool.

v0.7.0 — Suggest Buys (2026-05-23)

• New tool: suggest_buys — composes advisor profile + allocation drift + asset screening into a deterministic list of BUY suggestions per underweight asset class.
• Encodes a fixed objective × asset_class screening matrix (income/growth/balanced × FII/ACAO/ETF).
• Non-screenable underweight classes (TESOURO, RENDA_FIXA_PRIVADA, FUNDO) surface in a dedicated skipped_classes field rather than being silently dropped.
• Each suggestion includes amount_brl (= class gap / actual_returned), score, rationale, and already_owned.
• 12 tools total (was 11). No schema migration.

Development

For contributors or anyone who wants to run a local checkout instead of the published npm package:

git clone https://github.com/Satsuj1n/portfolio-mcp
cd portfolio-mcp
npm install
npm run build
npm run test

Then point claude_desktop_config.json at the local build:

{
  "mcpServers": {
    "portfolio": {
      "command": "node",
      "args": ["/absolute/path/to/portfolio-mcp/dist/index.js"]
    }
  }
}

Run the type checker with npm run typecheck. Smoke-test the MCP server end-to-end with:

node dist/index.js <<'EOF'
{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"local","version":"0.0.0"}}}
{"jsonrpc":"2.0","method":"notifications/initialized"}
{"jsonrpc":"2.0","id":2,"method":"tools/list"}
EOF
