Catalyst Edge MCP
The Catalyst Edge MCP server provides source-linked market intelligence for AI agents, delivering deterministic catalyst evidence dossiers and immutable source records for public-company tickers (including ETFs like SPY, QQQ).
Tools:
catalyst_edge_score: Returns a compact dossier with a 0-100 score, direction (bullish/bearish/neutral), confidence, and evidence summary (headline, what changed, why it matters, what would invalidate). Evidence is categorized by families (SEC filings, insider trading, GDELT Web NGrams, issuer feeds, Bluesky social attention, options flow, technical analysis) and includes strength, confidence, source quality, and change descriptions. Reports data quality (coverage, missing/stale families, warnings) and suggests next checks. Configurable lookback (1-90 days), risk modes (research,alert_triage,thesis_review), and options to include/exclude sources or raw signals. Handles missing data gracefully (neutral score, not bearish).catalyst_edge_claim_sources: Pages through immutable source records for a grouped claim (identified byclaim_id), returning up to 20 sources per page with cursor-based pagination. Each record includes source ID, name, tier, URL, timestamps, SHA-256 hash, parser version, and policy decision.
Key characteristics: Read-only, deterministic and unbacktested scoring, full source provenance, typed missingness (never treats missing data as bearish), local/offline operation via stdio or HTTP, and explicit disclaimers (no investment advice).

CATALYST/EDGE

Source-linked market intelligence for AI agents.
Catalyst Edge is a local, read-only Model Context Protocol server for public-company research. Ask an agent what changed for a ticker, why it matters, what contradicts it, and which sources support the answer.
It combines direct SEC filings and ownership records with optional, policy-gated sources into a compact evidence dossier. Every result preserves its source links and missing-data warnings.
Local first. Evidence and configuration stay on your machine. Research only. The deterministic scorer is untrained and unbacktested; Catalyst Edge does not provide investment advice, trading signals, or execution.
Install
Catalyst Edge requires Python 3.10+ and uv.
The SEC requires an identifiable User-Agent; use your organization and a monitored
email address.

Use
Ask your agent a focused research question, for example:
What changed for NVDA in the last 14 days? Include sources, missing evidence, and anything that would weaken the conclusion.
The primary tool accepts a ticker, a 1–90 day lookback, source inclusion, and a research context:
{
"ticker": "NVDA",
"lookback_days": 14,
"include_sources": true,
"include_raw_signals": false,
"risk_mode": "research"
}risk_mode also supports alert_triage and thesis_review. Ticker validation runs
before any provider is composed; invalid inputs fail clearly rather than producing a
partial score.
From a terminal
# Run the local stdio MCP server
uvx --from 'catalyst-edge-mcp==0.1.8' catalyst-edge-mcp
# Get a dossier directly
uvx --from 'catalyst-edge-mcp==0.1.8' catalyst-edge-score NVDA --lookback-days 14What it uses
Evidence | Default | Notes |
SEC filings and ownership records | Enabled with | Primary regulatory evidence. |
GDELT Web NGrams discovery | Enabled | Attributed, cache-only discovery metadata; set |
Issuer RSS/Atom feeds | Disabled | Enable explicitly with |
Bluesky public attention | Disabled | Enable explicitly with |
Options, technicals, and sentiment | Disabled | Not composed without an approved, rights-cleared provider. |
The default evidence store is local SQLite at
~/.local/state/catalyst-edge-mcp/evidence.sqlite3. Set
CATALYST_EDGE_EVIDENCE_STORE to choose another local path.

How to read a result
Each dossier includes a deterministic score, direction, confidence, source-linked
evidence, missing or stale families, and next checks. research.disposition tells an
agent whether to review the evidence now, monitor it, or report insufficient evidence;
it prioritizes research only and is not a trade signal. model_status is always
not_trained in this release. A neutral or no-data result is a valid answer: missing
evidence is uncertainty, not bearish evidence.
Evidence is compact by design. Use catalyst_edge_claim_sources with a claim ID to
retrieve its paginated source records, including canonical URLs, timestamps, hashes,
parsers, and policy decisions.

TDQS
Scored across 2 tools
Each tool targets a distinct function: one for generating/assessing research scores on a ticker, the other for retrieving source records for a specific claim ID. No overlap in purpose or inputs.
Both tools share the 'catalyst_edge_' prefix and use snake_case with a clear noun structure. The pattern is consistent and predictable, making it easy to infer each tool's role.
With only two tools, the server has a minimal but plausible scope. While each tool clearly serves a distinct purpose, the very low number makes the set feel thin and raises expectations for more coverage.
The two tools cover a core research workflow (get score, then read claim sources), but the server lacks other potentially useful operations such as listing dossiers or searching claims. Given the apparent narrow domain, the surface is reasonably complete for a read-only assistant, though a bit minimal.
