Local MCP Server - 0xinsider API

@0xinsider/mcp is the official local Model Context Protocol server. It exposes the same intelligence as the REST API — trader grades, whale trades, smart-money flow, positions, insider detection — as MCP tools your agent can call directly. Works with Claude Code, Cursor, Codex, Gemini CLI, and any client that speaks stdio MCP.

Need a hosted HTTP endpoint instead of a local subprocess? See Remote MCP.

Install — one command

npx -y @0xinsider/mcp init

init auto-detects which clients you have installed and writes the right config block in the right place. You will be asked for your API key once. If you prefer to edit configs by hand, the per-client paths and snippets are below.

Other clients

~/.claude/settings.json

{
  "mcpServers": {
    "0xinsider": {
      "command": "npx",
      "args": ["-y", "@0xinsider/mcp"],
      "env": { "OXINSIDER_API_KEY": "oxi_sk_live_..." }
    }
  }
}

~/.cursor/mcp.json (restart Cursor after saving)

{
  "mcpServers": {
    "0xinsider": {
      "command": "npx",
      "args": ["-y", "@0xinsider/mcp"],
      "env": { "OXINSIDER_API_KEY": "oxi_sk_live_..." }
    }
  }
}

~/.codex/config.toml

[mcp_servers."0xinsider"]
command = "npx"
args = ["-y", "@0xinsider/mcp"]

[mcp_servers."0xinsider".env]
OXINSIDER_API_KEY = "oxi_sk_live_..."

~/.gemini/settings.json

{
  "mcpServers": {
    "0xinsider": {
      "command": "npx",
      "args": ["-y", "@0xinsider/mcp"],
      "env": { "OXINSIDER_API_KEY": "oxi_sk_live_..." }
    }
  }
}

Gemini exposes the tools through /mcp.

Any stdio-MCP client works:

OXINSIDER_API_KEY=oxi_sk_live_... npx -y @0xinsider/mcp

See all options:

npx -y @0xinsider/mcp --help

What the server exposes

Tools (read-only)

Tool	What it does
`get_trader`	Wallet profile — grade, P&L, win rate, strategy, category strengths.
`get_whale_trades`	Recent large trades, filterable by size, category, grade.
`get_leaderboard`	Top-ranked traders (S/A/B) with optional category/strategy filter.
`get_positions`	Current positions across traders or markets.
`get_position_timeline`	Per-market trader fills with running amount and average entry price.
`search_markets`	Keyword search across prediction markets.
`explore_markets`	Browse whale-active markets by category, platform, status.
`get_market_intel`	Smart-money breakdown for a single market.
`get_insider_radar`	Suspicious accumulation and timing patterns.

All tools advertise readOnlyHint: true. The server cannot place trades or write data.

Resources (auto-attached context)

URI	What you get
`oxinsider://docs/api`	Full API reference, ready for the model to read.
`oxinsider://docs/agents`	Decision tree for agents — when to use which tool.
`oxinsider://data/leaderboard`	Live top 20 traders.
`oxinsider://data/whale-trades`	Live latest 20 whale trades.

Prompts (one-shot templates)

Prompt	Use when
`analyze_trader`	You want a full breakdown of a specific wallet.
`market_report`	You want smart-money flow on a market topic.
`trading_signals`	You want a scan for high-conviction signals across markets.

Try it

After install, ask your agent things like:

“Who are the top prediction-market traders right now?”
“What are A-grade or better whales buying in crypto markets today?”
“Analyze trader 0x863134d00841b2e200492805a01e1e2f5defaa53 — is their strategy worth following?”
“Are there suspicious accumulation patterns on the Trump election market?”
“Show me the position timeline for that whale on the Ethereum market.”

The agent will pick the right tool and call it for you.

Environment variables

Variable	Required	What it controls
`OXINSIDER_API_KEY`	Yes	Your API key (`oxi_sk_live_...`).
`OXINSIDER_API_URL`	No	Override the base URL (mostly for self-hosted dev).

The MCP server uses your normal API key and shares the 100 req/min rate limit with direct API access. One key, one budget. Get yours at 0xinsider.com/developers.
