Undertow MCP | Market liquidity and exit-cost tools

Connect and ask one question

Hosted Streamable HTTP MCP; no local server or API key for public read-only tools. Add the products you need to Claude Code:

claude mcp add --transport http undertow https://api.seiche.info/undertow/mcp

claude mcp add --transport http liquilens https://api.liquilens.in/mcp claude mcp add --transport http seiche https://api.seiche.info/mcp

Try this first: What is the estimated exit cost for a $100,000 BTC sell? Compare available venues, snapshot times and excluded costs.

Try it in your browser · Cursor configuration · Codex commands · Free three-product starter kit and skill

For a connected review, ask for institution evidence → funding context → BTC exit estimates, with each source date, coverage gap and limitation kept separate. Client/model costs and fair-use limits may apply. Research calls do not execute trades.

Endpoint: https://api.seiche.info/undertow/mcp (streamable HTTP, no install)

Undertow is the market-liquidity product of LIQUILENS PRIVATE LIMITED, a registered company in India (CIN U62011RJ2026PTC116792). One company, three connected financial-evidence products: LiquiLens investigates institutions, Seiche explains funding conditions, and Undertow examines market exit evidence. Together they support a review of an exposure from institution to funding to liquidity, with each source date, coverage gap and research limit retained.

Built for people and AI agents working internationally. Access is global; coverage is market-specific. Read the company and investor story or inspect the shared company profile.

Start with a question: Open the crypto workbench. Choose a dollar size and click to read the current published venue estimates, snapshot date and method. No account, key, wallet or client installation is needed for this example. The result is a depth-based estimate, not an executable quote. The same page provides Codex, Claude Code, Cursor and VS Code setup.

Try it live: liquilens-undertow.com/developers · API catalog: api.seiche.info/undertow

Undertow exposes estimated exit cost by position size and venue, the concentration of quoted depth, realized depth-collapse episodes, and liquidity tiers across market segments. This MCP 1.13.0 endpoint exposes 24 read-only tools, split into 16 public and 8 subscriber tools, plus 3 guided prompts. Its capability inventory is pinned to liquilens-undertow commit f103a9929a438f92964e7254edd7553c5a4dfe3a, the hosted implementation at deploy/hetzner/undertow-mcp. The stdio discovery server in undertow_mm/mcp_server.py is a separate discovery surface; it is neither this registry listing nor the public stdio adapter provided here.

The liquidity_tiers result includes public measure counts, replay eligibility and the published reason a score is withheld. A PARTIAL tier can remain even when every measure qualifies. Settlement histories and source receipts are available through the separate source-data MCP.

Add it

Claude Code:

claude mcp add --transport http undertow https://api.seiche.info/undertow/mcp

Claude.ai / ChatGPT / Cursor: add a custom connector or MCP server with the URL above. No key and no wallet for the free surface.

The free agent starter kit connects Undertow exit estimates and venue concentration with Seiche funding context and LiquiLens bank evidence. Follow the Hermes or OpenClaw guide for the shared setup. It uses public tools under fair-use limits; model-provider costs remain separate.

For a recurring research workflow, use the shared infrastructure setup guide and current interface catalog. They distinguish the public research MCPs, the eight-tool Research Desk and optional private runtimes. Private paper assessment is a separate integration; Undertow's public tools do not submit orders. Source observation dates, data rights and eligibility remain explicit even when hosting and backups are healthy.

This repository contains the discovery manifest, documentation and an optional anonymous stdio adapter for the hosted service. The official registry serves io.github.beepboop2025/undertow version 1.13.0.

Local stdio and container installation

The direct hosted URL above remains the simplest connection. For clients that require stdio, clone this repository at a reviewed commit and use Python 3.12+ and uv:

uv sync --locked

uv run --locked undertow-mcp

A Claude Desktop configuration can use uv as its command and ["run", "--directory", "/absolute/path/to/undertow-mcp", "--locked", "undertow-mcp"] as its arguments. The stdio adapter exposes only the 16 anonymous tools and three prompts; subscriber access uses the direct hosted URL instead.

For Docker and Glama's container build:

docker build -t undertow-mcp .

docker run --rm -i undertow-mcp

The root Dockerfile runs as an unprivileged user and starts stdio directly. No API key, bearer token, wallet, port, volume or environment setting is needed. Outbound HTTPS access to the fixed api.seiche.info endpoint is required. Redirects, environment proxies and arbitrary upstream URLs are disabled. Requests are capped at 64 KiB, responses at 2 MiB, and each upstream operation at 10 seconds including queue wait. No automatic retries or response cache can hide outages or spend a quota twice. Upstream version/catalog drift fails closed. Tool results, native isError values and rights refusals are preserved.

A Glama maintainer can configure the root Dockerfile, complete its build test, and publish a Glama release from the listing's admin page. A GitHub commit or release does not create a Glama release. This repository does not claim a grade until Glama has actually rescanned and inspected it. See Glama's release guide.

Hosted protocol compatibility

2026-07-28: stateless requests use server/discover, per-request _meta, MCP-Protocol-Version, and mirrored Mcp-Method / Mcp-Name routing headers.
2025-11-25, 2025-06-18, and 2025-03-26: retained legacy initialization, tools, prompts, notifications, batching, and ping behavior.
Discovery identifies all sixteen public and eight subscriber tools. Anonymous tools/list returns only the public inventory; entitlement is checked fresh on every subscriber request.
resources/list and resources/templates/list return explicit empty catalogs. resources/read returns a not-found error and never invents a resource.

Example

In the snapshot generated at 2026-08-08T15:01:22Z, selling $1,000,000 of BTC at the selected $1,000,000 published size rung cost 2.386 bp on Binance and 13.623 bp on Bitfinex: about $238.60 against $1,362.30. Gemini was the dearest observed venue in that same snapshot at 25.852 bp, or about $2,585.20.

Venue rankings can change during the day, and those differences are not visible in a single consolidated price. Undertow publishes the observation time and venue inputs with the estimate.

Crypto workbench and skills

The browser workbench combines published BTC exit comparisons with funding and portfolio scenarios. The scenario forms run locally in the browser.

The crypto agent kit contains three installable skills, a standard-library Python client, offline scenario calculators and a repeatable brief connecting Undertow, Seiche and optional LiquiLens institution evidence. Exact file digests accompany the download. Nothing runs or installs automatically.
