Common questions

Is 0xinsider safe?

It passed 2 of 2 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: OXINSIDER_API_KEY

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (3.15.0) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

0xinsider Agent Plugin

The official Agent Plugin for 0xinsider - Polymarket analytics & infrastructure for sports and esports markets.

It bundles the 0xinsider MCP server with five skills that teach an agent how to read large trades, wallet grades, sharp-money flow, and published research without misreporting them.

Install

npx skills add 0xinsider/agent-plugin

Refresh an existing installation with:

npx skills@latest update 0xinsider-api-access polymarket-whale-trades polymarket-wallet-grades polymarket-sharp-money polymarket-market-research

Or install one skill without adding the whole plugin:

npx skills add 0xinsider/agent-plugin --skill polymarket-wallet-grades

Skill	Covers
`0xinsider-api-access`	Credentials, sandbox vs live hosts, MCP transports, rate limits, deprecated paths, typed errors
`polymarket-whale-trades`	Large-trade feed, history replay, counterparties, review score
`polymarket-wallet-grades`	Trader grades, sports and esports P&L, category records, leaderboards, position timelines, exports
`polymarket-sharp-money`	Market flow, graded holders, candles, Max-only Edge Hunter board/full signals/cohort observations, suspicious-trade flags
`polymarket-market-research`	Market search and explore, games, published research, report snapshots, Pick of the Day, coverage

Plugin 1.3.0 re-syncs every skill with the live API and MCP server. Calls use the canonical paths and tools (/large-trades, /suspicious-trades, /market/{condition_id}/flow, /markets/flow/batch, /markets/sharp-money-flows, /coverage); the older names are listed only as deprecated aliases, which stop working on 2027-02-01. A wallet's P&L is pnl.in_scope.realized_pnl, because pnl.realized has not been sent since 2026-10-27. The large-trade score is review_score, {address} accepts usernames, exports start with a POST, rate limits are per plan (100 a minute on Pro, 200 on Max), polymarket.com links carry via=0xinsider then r=0xinsidercom, and mcp.json now validates against the Agent Plugins 1.0.0 MCP schema and points at the canonical endpoint https://api.0xinsider.com/api/v1/mcp.

Plugin 1.2.0 documents configurable selections across every Edge Hunter view: sports/esports, canonical sports, exact leagues, market types, markets, events and series. Board defaults remain compatible; rows add frozen market_context for authoritative selector discovery, and selected responses echo normalized selection. Advanced records retain pagination, evidence and conditional reads. Selections need TypeScript SDK 0.22.0 or later and CLI/MCP runtime 3.2.0 or later. The four legacy URLs/tools remain retired.

AGENTS.md holds the rules for AI coding agents writing integration code against the API. .cursorrules mirrors it.

MCP server

mcp.json points at the remote Streamable HTTP endpoint:

"mcpServers": { "0xinsider": { "type": "streamable-http", "url": "https://api.0xinsider.com/api/v1/mcp" } } }

It carries no credential. Agent Plugins clients do not expand environment variables in headers, so the client signs in on the first tools/call: the 401 names the OAuth 2.1 protected-resource metadata, and the authorization server supports dynamic client registration and PKCE. To use an API key instead, add the server to your client's own MCP configuration. In clients that expand ${VAR} in headers, such as Claude Code's .mcp.json:

"mcpServers": { "0xinsider": { "type": "http", "url": "https://api.0xinsider.com/api/v1/mcp", "headers": { "Authorization": "Bearer ${OXINSIDER_API_KEY}" } } } }

The server exposes tools across traders, markets, games, large trades, positions, flow, research, reports, and webhooks: 55 on 2026-10-28, nine of them deprecated aliases. initialize, ping and tools/list need no credential, so tools/list is always the current catalog; tools/call takes an API key or an OAuth 2.1 token. Its card is at /.well-known/mcp. https://0xinsider.com/mcp answers with the same tools, but OAuth clients should use the endpoint above, which the protected-resource metadata names.

A local stdio path ships in the CLI:

npx -y @0xinsider/mcp@latest init

Try it with no account

Every documented operation answers from the sandbox with no credential:

curl -s https://0xinsider.com/sandbox/api/v1/leaderboard

One POST returns a sandbox key and the steps to live access:

curl -s -X POST https://api.0xinsider.com/api/v1/agents/register \

-H 'Content-Type: application/json' -d '{"name":"my-agent"}'
