Financial Hub Mcp

Financial Hub MCP Server

A TypeScript MCP server for financial data aggregation. Connects any MCP-compatible AI assistant to SEC EDGAR filings, XBRL financial statements, FRED economic indicators, and real-time market data — with built-in XBRL normalization, fact deduplication, computed analytics, stock screening, and rate-limit protection.

Core Concepts

SEC EDGAR

All SEC EDGAR data comes directly from the SEC's free public APIs at data.sec.gov. No API key is required. The server automatically handles:

• XBRL concept resolution — Different companies use different XBRL tags for the same metric. The server normalizes across 20+ financial concepts (e.g., revenue resolves to Revenues, RevenueFromContractWithCustomerExcludingAssessedTax, SalesRevenueNet, and 11 other variants).
• Fact deduplication — Raw XBRL data contains duplicate values from overlapping 10-K/10-Q filings and amendments. The server collapses these to one clean value per fiscal period.
• Rate limiting — SEC enforces 10 requests/second. A token-bucket rate limiter with bounded queuing (max 50 pending, 30s timeout) prevents IP bans.

FRED

FRED (Federal Reserve Economic Data) provides 800,000+ time series from 100+ sources. Requires a free API key from fred.stlouisfed.org. Rate limited to 120 requests/minute (enforced via 2 req/s token bucket). Includes a curated catalog of ~50 essential economic indicators across 9 categories for zero-API-call browsing.

Finnhub Market Data

Real-time stock quotes, company profiles, market news, insider transactions, and financial metrics via the Finnhub API. Free tier provides 30 API calls/second with no credit card required. The server rate-limits to 25 req/s to stay safely under the threshold. Quotes are never cached (stale prices are worse than no cache), while profiles (24h), news (5min), and financial metrics (1h) use appropriate TTLs.

Caching

In-memory LRU cache with TTL expiry reduces redundant API calls:

Eviction is LRU — frequently accessed entries are promoted on read, so the least recently used entry is evicted when capacity is full. Expired entries are proactively swept on every write.

Tool Annotations

All tools set MCP ToolAnnotations for safe agent composition:

Error Handling

All tools return MCP-compliant error envelopes with isError: true on failure:

{  "content": [{ "type": "text", "text": "SEC EDGAR request failed: 404 Not Found" }],  "isError": true}

This allows the LLM to receive semantic error messages, correct parameters, and retry — rather than receiving opaque transport-level JSON-RPC errors that break the agent loop.

Usage with Claude Desktop

Add this to your claude_desktop_config.json:

NPX

Data Pipeline

Raw XBRL data from SEC EDGAR goes through several processing stages:

1. Rate-limited fetch — Token bucket ensures SEC's 10 req/s limit is never exceeded. Queue rejects after 50 pending requests or 30s wait.
2. Caching — Company facts cached for 1 hour, max 15 entries to avoid OOM on large payloads.
3. Concept resolution — Friendly names like revenue are mapped to all known XBRL tag variants across the us-gaap taxonomy.
4. Deduplication — Overlapping 10-K/10-Q/amendment values are collapsed to one per fiscal period. Prefers 10-K over 10-Q, latest filing date over earlier.
5. Analysis — Growth rates, CAGR, financial ratios, and health scores are computed from clean data.
6. Serialization — Minified JSON output to minimize context window usage.
