How to use Finance MCP Directory
Catalog of finance MCP servers (Alpaca, Polygon, Databento, IBKR, Tradier, Tiingo, NautilusTrader) graded on scope, auth, idempotency, transport, and schema discipline so you can pick a server that won't blow up under agent load.
What It Does
Use the calculator with intent
Catalog of finance MCP servers (Alpaca, Polygon, Databento, IBKR, Tradier, Tiingo, NautilusTrader) graded on scope, auth, idempotency, transport, and schema discipline so you can pick a server that won't blow up under agent load.
Engineers wiring an LLM-driven trading agent who need an MCP server with predictable failure modes, not the one with the longest README.
Interpreting Results
Match scope to your agent's task: a server with great market-data but no order management is fine for research, dangerous for execution. Idempotency grade B or worse means duplicate orders during retries.
Input Steps
Field by field
- 1
Filter
Filter by scope (read-only vs. read-write) — read-write servers can place orders and need much more scrutiny.
- 2
Sort
Sort by security grade (A/B/C). Skip C-grade servers for production use.
- 3
Click
Click into a server entry. Verify the listed manifest URL still resolves and the auth method matches your deployment.
- 4
Step 4
Cross-check the security axes: scope clarity, authentication, idempotency, transport, audit logging. All five matter for production.
- 5
Test
Test in paper mode first. Even an A-grade server can have edge-case bugs that surface only at integration time.
Common Scenarios
Use realistic starting points
Research-only agent (no live orders)
Required scope
market-data
Auth tolerance
API-key
Polygon + Databento score high on schema discipline; Alpaca a strong backup with same-vendor broker integration if research becomes execution.
Live-execution agent
Required scope
orders + positions
Idempotency requirement
A
IBKR + Tradier filter on idempotency grade; check rate-limit headroom against agent loop frequency before committing.
