VerifiedSSEWeb executableFinanceData & Analytics

Overview

AI-generated overview

Remote MCP endpoint that analyzes Uniswap V3 pool liquidity depth, returning price impact at 1/2/5/10% levels for trade sizing.

What you can do
Analyze Uniswap V3 pool liquidity depth, returning current price, USD liquidity available within 1%, 2%, 5% and 10% price impact, total liquidity, fee tier and token pair symbols for a given pool address and chain (base or ethereum). The same analysis is offered as a GET and a POST variant.
When to use it
Useful before executing large on-chain trades to estimate slippage and choose a trade size, or for agents doing MEV-aware or OTC sizing on Uniswap V3 pools. Not intended for swap quotes, token safety checks or holder analysis.
Requirements
A remote MCP endpoint reached over SSE; no API key or signup. Each call is paid per request in USDC on Base L2 via the x402 protocol, so an x402-aware client and a funded wallet are needed to complete the 402 payment challenge.
Before you install
Every call costs $0.012 in USDC on Base, so an assistant can spend real money; a wallet and payment signing are involved. Pool addresses and chain names are sent to a third-party service. Results are liquidity estimates, not trade advice.

Installation

In SourceWeft

  1. Open Order Book Depth API in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via SSE. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Br0ski777%2Forderbook-depth/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

Order Book Depth API

[MCP Server] [x402] [License: MIT]

Uniswap V3 liquidity depth analysis -- price impact at 1/2/5/10% levels. Slippage estimation pre-trade. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.

Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

json
{  "mcpServers": {    "orderbook-depth": {      "url": "https://orderbook-depth.api.klymax402.com/mcp"    }  }}

Quickstart -- HTTP (x402)

bash
curl "https://orderbook-depth.api.klymax402.com/api/depth?pool=..."# -> 402 Payment Required, with an x402 payment challenge in the response body

Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 daysRequired25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declaredRequired10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
