Seiche
Seiche is an open-source money-, foreign-exchange, and capital-market evidence terminal, with its deepest live coverage in US-dollar funding. It joins public and official sources from the Federal Reserve, New York Fed, OFR, US Treasury, CFTC, and other authorities into a source-clocked research surface.
Every output keeps its as-of date, provenance, evidence status, known gaps, and point-in-time eligibility attached. Seiche is a research and evidence tool—not a real-time quote service, execution venue, or investment adviser.

Install and run
Seiche requires Python 3.12 or newer.
python3.12 -m venv .venv
.venv/bin/pip install seiche
.venv/bin/seiche pull
.venv/bin/seiche brief
Start the local REST API and terminal UI with:
.venv/bin/seiche serve
The first pull can be slower while the local cadence-aware cache is populated. Subsequent reads reuse that cache and continue to expose stale or unavailable inputs explicitly instead of silently dropping them.

Seiche is a Model Context Protocol server. Run it locally over stdio:
SEICHE_MCP_PUBLIC=1 .venv/bin/seiche-mcp
Or connect an MCP-capable client directly to the public Streamable HTTP server:
https://api.seiche.info/mcp
The public trade_safety_risk_context tool returns only the last completed
Seiche regime, index, coverage, source-status counts, and conservative clocks.
It is metadata-only derived context, never an executable or real-money-eligible
claim, and does not inspect the attestation ledger. Stream attestations are
verified separately and never confer per-order execution authority.
Fourteen evidence/context tools are anonymous: the current funding-stress read,
cache-only Trade Safety context, historical analogs, public backtest, data
health, crypto record, institutional flows, oil/funding, FX/materials, US money
markets, world markets, connected research (research_network), structured FX and China (market_workbench), and the latest article. Five higher-cost forecast,
replay, positioning, prose, and LLM tools
require an account and are omitted from anonymous tools/list responses.
Authenticated hosted MCP adds five private Agent Room preview tools for
identity-to-key binding, room creation, signed append, verified listing, and
full-chain verification. The same protected operations have REST twins under
/api/agent-room/. They are discussion and evidence primitives only: every
record is non-executable, x402 cannot unlock them, and local stdio has no bearer
principal with which to expose them. See docs/AGENT-ROOM.md.
The canonical registry ownership marker is:
mcp-name: io.github.beepboop2025/seiche
See the MCP integration guide for Claude, Codex, Cursor, VS Code, and raw JSON-RPC examples.
Data and licensing boundary
The source code is licensed under AGPL-3.0-or-later. Upstream data keeps its own terms: Seiche's software license does not grant redistribution rights over data from third parties. Public outputs distinguish redistributable observations, bounded derived context, metadata-only sources, restricted inputs, and declared gaps.
