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](#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](./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  **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](https://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] PDF parser for XPerformance (XP's official portfolio report)
• [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 f
