Finance MCP servers
Two questions decide this: can it place a trade, and what licence does connecting it drag in.
AGPL is common here and is a real blocker if you serve anything over a network.

in awesome-lists), ArjunDivecha/ibkr-mcp-server (archived), rcontesti/IB_MCP (stale 2025-10).
⚠️ BlockRunAI/awesome-finance-mcp (208★) is a vendor-marketing list with no licence, stale 6+
months — do not treat it as a neutral index.
2. 🚨 Licence posture
AGPL-3.0 servers: SEC EDGAR (stefanoamorelli), FRED (stefanoamorelli), OpenBB. AGPL is
network copyleft — if you expose the functionality over a network, §13 obliges you to offer the
complete corresponding source of the combined work. For EDGAR there is a permissive alternative
(cyanheads/secedgar-mcp-server, Apache-2.0); for FRED and OpenBB there is not, so either accept
the terms or call the underlying APIs directly (fredapi is Apache-2.0; FRED's REST API needs only
a free key).
Code licence ≠ data licence. A MIT-licensed Yahoo MCP still delivers Yahoo data under Yahoo's
personal-use terms. See market-data-sourcing §2d.
3. 🚨 Blast radius — servers that can move money
alpacahq/alpaca-mcp-server places real orders. Before connecting any order-capable server:
- Point it at paper credentials and verify the account is paper from a server-returned fact,
not a config flag (
broker-execution-apis §3.1).
- Give it API keys scoped to trade only, never withdraw.
- Assume any instruction reaching the model from a tool result, web page, filing or news item is
untrusted data, not a command — an order-capable MCP turns a prompt-injection into a trade.
- Keep a hard notional/count cap outside the model's reach.
4. Where the gaps are
The ecosystem is thick with redundant API wrappers and thin on everything else. Nothing exists for:
- Ken French / Fama-French factor data — no MCP or skill found. Factor-adjusted alpha is
unbuildable without it, which is precisely why almost no LLM-trading paper reports it.
- Point-in-time / survivorship-free universes — the hardest data problem in the domain; the only
implementations found are hobby repos with 0–1 stars.
- Per-provider machine-readable licence records (
may_cache / may_redistribute / may_derive
/ display_only / rate_limit). Every vendor differs; nobody encodes it.
- MCP wrappers for the big permissive libraries —
FinanceToolkit (5,286★ MIT), edgartools
(2,649★ MIT), defeatbeta-api (744★ Apache-2.0) all lack dedicated servers. Low effort, high leverage.
5. Libraries actually backing these servers
Prefer calling these directly when an MCP adds nothing but a licence problem:
