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.
Catalyst Edge requires Python 3.10+ and uv.
The SEC requires an identifiable User-Agent; use your organization and a monitored
email address.
Start a fresh task and verify that Codex discovers these two tools:
| Tool | Use |
|---|---|
catalyst_edge_score | Return a compact catalyst-evidence dossier for a ticker. |
catalyst_edge_claim_sources | Page through the immutable source records behind a claim. |
Download catalyst-edge-mcp-0.1.8.mcpb,
then choose Settings → Extensions → Advanced settings → Install Extension….
Enter the same SEC identity when prompted. The extension is an unsigned custom bundle;
review the source and published checksum before accepting Claude Desktop's warning.
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:
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.
| Evidence | Default | Notes |
|---|---|---|
| SEC filings and ownership records | Enabled with CATALYST_EDGE_SEC_USER_AGENT | Primary regulatory evidence. |
| GDELT Web NGrams discovery | Enabled | Attributed, cache-only discovery metadata; set CATALYST_EDGE_GDELT=disabled to opt out. |
| Issuer RSS/Atom feeds | Disabled | Enable explicitly with CATALYST_EDGE_ISSUER_FEEDS=enabled. |
| Bluesky public attention | Disabled | Enable explicitly with CATALYST_EDGE_BLUESKY=enabled; it is incomplete, neutral-only context. |
| 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.
The smoke check reports sanitized configuration, provenance, coverage, and readiness status. It never prints credentials or provider payloads.
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.
Results and SQLite evidence remain on your machine. Ticker and issuer queries may be
sent directly to whichever public-source providers you enable. The SEC identity is sent
only to sec.gov as its required request User-Agent.

Default tests are offline and use sanitized fixtures. The release workflow tests Python 3.10 and 3.14, MCP contracts, a clean build, and the packaged artifact.
