Undertow market liquidity and exit-cost tools tools (16)

write = sends, deletes, buys or posts
  • agent_access_statusFree

    Identity, current entitlement, daily usage and access instructions; explains missing/refused subscriber tools.

  • crypto_exit_checkFree

    Compare four BTC sell sizes by rung/bracket. Withholds stale/future, uncovered or unconverted venues. Fees excluded; no trade clearance.

  • crypto_funding_costFree

    Caller-input perpetual funding, fees, net carry and linear break-even. Positive funding: longs pay shorts. Constant-rate scenario, not forecast.

  • crypto_portfolio_stressFree

    Caller-input linear shocks for 20 exposures: P&L, equity, asset/venue concentration. Symbols are scenario labels. No liquidation/probability model.

  • depth_episodesFree

    Realized BTC depth-collapse onset, trough, recovery under preregistered rules. Zero is distinct from missing. Subscriber exit_desk_full adds ETH.

  • exit_costFree

    BTC nearest-rung sell estimates, interpolated bid-depth bands; fees excluded, not executable. crypto_exit_check compares sizes/freshness.

  • gold_cash_realisationFree

    Calculate gold sale proceeds and cash gates from caller inputs. Decimal strings: kg, fineness (0,1], USD/troy-oz bid, USD fees, currency/USD FX (USD=1). Use aware ISO clocks. Returns arithmetic and withheld-cash reasons; no fetch, storage, execution or verified balance.

  • latest_articleFree

    Read the latest published editorial: title, full text, URL, clock and quality receipt. No arguments. Missing text or failed receipt returns an error; no generated prose. Use liquidity_tiers for board data.

  • liquidity_tiersFree

    Nine segment tiers, Seiche funding, measure counts and replay/withholding reasons. PARTIAL means missing history or unpassed replay, never calm.

  • market_corpus_contextFree

    Inspect corpus coverage, rights and clocks. Summary takes no pagination; other views return records/total/next_offset. Retrieval age is not observation freshness. Use liquidity_tiers for market readings.

  • research_networkFree

    Find cross-product source metadata, clocks, rights and next steps. Follow next_offset; unavailable flags retrieval, contract or size failure. Use market_corpus_context for local corpus counts. No shared score or authority.

  • sealed_recordFree

    Forward calls sealed/signed before outcomes: hits, misses, decided counts, ledger root. Report hits and misses together.

  • trade_safety_exit_contextFree

    Exact-rung BTC/USD observe/paper context: request hash, PIT source/rights, conversion, bid bands, six venue clocks, startup SHA. No live mode or clearance.

  • unwind_watchFree

    Watched-filer headlines: effective positions, days-to-exit brackets, blind spots. No live execution model. unwind_stress has full scenario grids.

  • venue_concentrationFree

    BTC two-sided depth: HHI, effective/top venue and venue depth. Subscriber exit_desk_full adds ETH and venue failure.

  • venue_price_reconciliationFree

    BTC/ETH consensus: depth/squared-half-spread weights, deepest-venue blindness, concentration, dislocations. Experimental; no execution authority.

Undertow MCP | Market liquidity and exit-cost tools

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

Start with a question: Compare BTC exit estimates in your browser. 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 1.10.0 endpoint exposes 19 read-only tools, split into 11 public and 8 subscriber tools, plus 3 guided prompts. Its capability inventory is pinned to liquilens-undertow commit e472d8862f6317fe5a28ad9a33c093a22d14590a, the hosted implementation at deploy/hetzner/undertow-mcp. The stdio discovery server in undertowmm/mcpserver.py is a separate discovery surface; it is neither this registry listing nor the public stdio adapter provided here.

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.

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 1.10.0.

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 11 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.
