Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@nyx-fund-mcp Calculate fees for a $10M fund with 1.5% management and 20% performance."
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
MCP server for hedge fund operations. Give Claude, Cursor, or any MCP client a fund back office: management/performance fee calculators (with high-water mark), NAV validation, exposure analysis, operating-cost and back-office-savings models, LP report grading, and searchable fund-ops docs — powered by Nyx Fund.
The public server is free and requires no API key or signup.

Tool | What it computes |
| Management + performance fees over a multi-year horizon, with a per-period high-water mark, fee drag, and net-of-fee CAGR |
| Cross-checks a reported NAV against positions and flags the discrepancy |
| Scores fund operational health across fees, ops, and reporting |
| Gross/net/long/short exposure and concentration from a position list |
| Annual fund operating-cost model |
| Back-office cost vs. software-replacement comparison |
| Grades an LP report's completeness against institutional norms |
| Searches the Nyx Fund developer docs and API reference |
All calculator outputs are illustrative computational tools, not accounting, tax, or investment advice.
Nyx Fund customers can point any MCP client at their own fund's live data (positions, NAV history, exposure, risk, capital accounts — read-only, redacted) with a scoped API key:
npx -y nyx-fund-mcp --api-key nyx_sk_...Keys are minted in the Nyx Fund dashboard (Settings → API keys). See the MCP docs.
Is there an API version of these tools? Yes — every calculator is also a REST endpoint (POST https://nyxchain.org/api/v1/calc/<slug>), documented with OpenAPI 3.1 at nyxchain.org/api/v1/openapi.json. Full reference: nyxchain.org/developers · machine-readable: nyxchain.org/llms-full.txt.
How do I calculate hedge fund fees with a high-water mark? Call calc_fee_calculator with AUM, management fee %, performance fee %, and expected gross return — it simulates the fee schedule year by year, banking crystallized performance fees against a per-period high-water mark, and reports total fees, fee drag, and net-of-fee CAGR.
