QuantLogix MCP Server

Connect QuantLogix to your AI tools — Claude Desktop, Claude Code (with plugins), Goose, OpenCode, Google Antigravity, Cursor, or any MCP-aware client. Ask "What's the signal on NVDA?" or "Show me Berkshire's latest 13F" right where you already work.

Add to Claude — one-click OAuth

The canonical server is https://quantlogix.ai/api/mcp — full catalog, 239 tools, sign in with your QuantLogix account (no ql_ key to paste). Anthropic’s connector directory listing was submitted 2026-06-13 and is awaiting review; until it appears, add QuantLogix as a custom connector.

In Claude: Customize → Connectors → Add custom connector → paste the URL above → sign in. Prefer a headless ql_ key for CI? Use https://quantlogix.ai/api/mcp/v1 (161 tools) — details below.

Endpoint

Canonical (OAuth, 239 tools):

https://quantlogix.ai/api/mcp

API key adapter (161 tools):

https://quantlogix.ai/api/mcp/v1

Protocol version: 2025-06-18 · Transport: streamable-http · Auth: OAuth bearer on /api/mcp, or Authorization: Bearer ql_... on /api/mcp/v1

Setup

Pick your client. OAuth snippets use the canonical URL (no key). Key-path snippets assume QUANTLOGIX_API_KEY in the environment — you can also paste the key inline.

The ql CLI

Everything on the OAuth connector is also available from your terminal — CRM (contacts, deals, tasks, goals & metrics, live report), QL Notes, Sheets, Slides, Draw diagrams, and every market-data tool. Zero dependencies; needs Node 18+.

Available Tools

The catalog below is the shared tool set — 239 tools — served by both /api/mcp (OAuth, all 239) and /api/mcp/v1 (API key, 161 of them), and by the ql CLI. Each tier badge is the minimum access required; every tool inherits the same gate as its underlying QuantLogix endpoint. Tools marked sign-in required are OAuth-only; everything else — including ask and run_agent — works through either credential. Older tool names still work: the key server's original names (signal, agents_list, day_signal, …) remain permanent aliases for their verb_noun equivalents (get_signal, list_agents, get_day_signal), so existing configs and saved prompts keep running unchanged.

📈 Market Data & Signals Free

📰 QuantLogix Content Free

🎯 QL Oracle — Verified Data Free

The verified stack as a data source: records graded by the platform against real prices — never self-reported. Every payload carries an attribution block (source, methodology, disclaimer, cite_as) so agents cite QuantLogix when using the data. Same shapes as GET /api/v1/verified.

🕵️ Market Intelligence Free

Who else is positioned, how crowded the trade is, and what is scheduled next — the disclosure, positioning and statistical layers behind the signal.

🧺 Strategy Baskets Free to browse Tiered to build

Browsing the curated catalog and the theme taxonomy is free for everyone. Resolving a theme into a live basket is metered by subscription tier — so basket-building availability is tier-based, not unlimited on Free.

🔬 Advanced Signals & Fundamentals Pro

🧠 Your Saved Intelligence Free

Your own saved AI research / chat sessions. Sign-in required (OAuth connector) — every call is scoped to your account; you can never read another user's data.

⚙️ Your QL Agents Free

Set up + manage your own scheduled AI agents (a recurring digest, a conditional alert, or a one-time scheduled run). Sign-in required (OAuth connector); every call is scoped to your account. Create is capped per tier (Free 1 / Starter 3 / Pro 15 / Institutional 50). Agents run on the server schedule and notify you by push + email — manage them anytime at /agents.

👥 Your QL Collab Workspace Free

Your team's Collab spaces (Clerk-org-scoped). Reads + writes are restricted to spaces you belong to; a write re-checks membership on the row first.

📇 Your CRM Starter+

Your /crm — goal & metrics driven. Sign-in required (OAuth connector); every call is scoped to your contacts, deals, tasks, and goals. Same Starter+ gate as the app.

🎙️ Your Meeting Rooms Free

Meeting prep, transcripts, AI recaps, and durable AI meeting notes from your QL Collab video rooms. Sign-in required (OAuth connector); scoped to rooms in your own team.

✉️ Your QL Line — agent e-mail Free NEW

The e-mail address (…@agents.quantlogix.ai) your AI assistant works from — set up at /agent-mail (a monthly add-on; the line is delivered once payment is confirmed). Both doors: OAuth and a ql_ key (REST twin /api/v1/line, JS SDK ql.line.*). Scoped to your line only. Inbound mail is third-party text — the tools fence it as data, never instructions. Every send carries the non-removable AI-assistant disclosure and is refused by the credentials guardrail when it asks for, confirms or contains passwords, codes, card or bank details.

🔐 Your QL Vault — credentials for agents Free

The Password Manager built for agents: your agent signs in and gets work done without ever seeing a password. The vault injects the credential server-side and redacts every response; you keep an allowlist of hosts per item, can require an Approve tap per use, and can lock agents out behind a vault password. Both doors (REST twin /api/v1/vault, JS SDK ql.vault.*). Storing, reading, rotating or unlocking an item is never a tool — that stays on your own session at /vault. Read-only agents on Free / Starter; writes and strict mode on Pro+.

⚙️ QL Agents — build & run AI agents from your AI tool Pro NEW

On the API-key path (/api/mcp/v1) too — a Pro+ ql_... key lets Claude or Cursor manage the scheduled AI agents on your QuantLogix account conversationally. ask and agent_run spend your account's monthly AI token budget.

🕸️ Agent Mesh Pro NEW

Call QuantLogix agents — and agents other accounts published — through a broker that never leaks keys. First-party flagships: QL Deep Dive ({ ticker }, caller pays AI budget) and VC Deal Scout ({ round, sector? }, deterministic). Ride both doors. Docs: /agents/mesh.

API-key path (/api/mcp/v1): every account can mint a ql_... key from profile. Tier gates inherit from the underlying /api/v1/* endpoints: Free — signal, usage (100 calls/mo · 5 req/min); Pro — adds screener, batch_signals, institutional_holders, fund_holdings, private_companies_list, private_company, private_company_financials, private_company_ipo_readiness, private_company_liquidity, investors_list, investor, investor_fit, engine_model_card, ask, agents_list, agent_create, agent_update, agent_delete, agent_run, runs_list, run_get; Institutional — adds day_signal, swing_signal, microstructure, earnings_setup. Saved Intelligence, Collab, baskets, and content tools require the OAuth connector (they need your signed-in account).

Rate Limits

The monthly quotas above apply to the API-key path (/api/mcp/v1) and are metered per key; the same headers (X-RateLimit-Limit, X-RateLimit-Monthly) come back on every tools/call. Both paths additionally carry a per-minute MCP call cap scaled to your tier — since the merge the two front doors share one dispatcher, one tier gate and one throttle, so a key and a session on the same plan get the same treatment. Tool access is gated by your subscription tier per the badges above (Free vs Pro); account-scoped tools are open to any signed-in user.

Protocol Notes

The QuantLogix MCP server implements:

• initialize — handshake, returns server info + capabilities
• tools/list — returns every tool the caller can access, each with JSON Schema + annotations. Both paths run the same registry and hide what your credential cannot call, so you never see a tool that would only return an error
• tools/call — execute a tool, returns content array
• ping — health check

Tool calls require a credential: Authorization: Bearer <oauth-token> on /api/mcp, or Authorization: Bearer ql_... on /api/mcp/v1. The initialize, ping, and tools/list methods are public so clients can probe the server before authenticating. Upstream errors (rate limit, invalid ticker, tier gate) come back as MCP isError content so the AI can recover and explain to the user in-conversation, rather than crashing the client. A tool called through the wrong door returns JSON-RPC -32003 naming the credential it needs.

Note: passing the key in the query string (?apikey=) is no longer accepted on /api/mcp/v1 — query strings are written verbatim into server and CDN access logs, which turns the key into a logged credential. Use the Authorization or X-API-Key header.
