Key Glossary

Ten terms that appear everywhere in Synorb. Learn these first.

Term	What it is
Manifest	A content package containing a Signal, Brief, and Record. The unit Synorb delivers to you.
Signal	Structured claims extraction for reasoning systems completing workflows. Included on all plans.
Brief	Structured narrative for reasoning systems delivering information to human operators. Headline, summary, sentiment, significance.
Record	Source content — one article, one podcast episode, one data release. Enterprise plans only.
Claim	An atomic assertion extracted from a record. 15–50 per record. Each has a type, confidence level, and evidence classification.
Stream	A filtered delivery view. Streams organize content by theme — "Federal Reserve Watch", "AI Infrastructure", etc.
Tag	A resolved entity — person, organization, place, or data source. Tags link claims across records.
Topic	A curated thematic category from Synorb’s topic taxonomy, organized by domain. Used to filter streams by subject area.
Digest	A grouping of manifests. Synorb Digests are pre-curated and included on Enterprise plans. User Digests are built by your org (included in plan). Query either type for aggregated content.
Source Channel	A specific content feed within a stream. Each channel has an ID and display name (e.g. "Federal Reserve Bank of St. Louis"). Filter manifests by source_channel_ids.
Domain	One of 12 canonical knowledge domains. Every stream has a home domain and up to three cross-domains.

MCP Servers test live now ↓

Core MCP exposes 3 tools for the normal agent loop. Advanced MCP is a separate configured surface for account, digest, sync ontology, labels, prompt templates, and lower-level content tools. Both use the same Redis-backed cache layer.

$ connect mcp.synorb.com/sse Core loop — synorb-catalog, synorb-details, synorb-manifests mcp.synorb.com/advanced/sse Advanced tools — account, stream aliases, signals, briefs, records, digests, ontology, labels, help 9 prompts — morning-briefing, central-bank-watch, earnings-roundup, podcast-recap, vc-landscape, tech-pulse, research-briefing, competitor-watch, policy-tracker Compact mode: headlines + summaries by default. Set compact=False for full bodies. Auth: ?token=YOUR_TOKEN, Authorization Bearer, or x-access-token.

Setup

Core MCP — Claude Code / Cursor / Windsurf

{ "mcpServers": { "synorb": { "url": "https://mcp.synorb.com/sse?token=YOUR_TOKEN" } } }

Advanced MCP — configured workflows

{ "mcpServers": { "synorb-advanced": { "url": "https://mcp.synorb.com/advanced/sse?token=YOUR_TOKEN" } } }

ChatGPT / Other

Paste the Connector URL from your credentials page into your MCP connector settings.

Perplexity Computer

New Perplexity users can activate Synorb Free with email only. The response returns the Core MCP URL and token immediately, and the same credentials are emailed. Existing Synorb users validate with api-key and secret.

$ curl -X POST https://api.synorb.com/perplexity/free-credentials \ -H "content-type: application/json" \ -d '{"email":"user@company.com"}'

$ curl -X POST https://api.synorb.com/perplexity/auth/validate \ -H "api-key: YOUR_API_KEY" \ -H "secret: YOUR_API_SECRET"

Primary Agent Workflow

synorb-catalog

Find Streams from user intent. Search by topic, company, domain, media type, source domain, or broad exploratory query.

synorb-catalog(query='AI infrastructure earnings', home_domains=['economics-business-work'])

synorb-details

Inspect selected Streams before pulling. Returns source channels, media formats, available filters, volume, and a recommended Manifest call.

synorb-details(stream_ids=[17723038993540102, ...])

synorb-manifests

Pull Manifest triplets across one or more Streams. Supports stream_ids, home_domains, tag_names, tag_ids, media_format, source_channel_ids, significance, dates, compact/full output, and target_count diagnostics.

synorb-manifests(stream_ids=[...], tag_names=['AI infrastructure'], significance='high', target_count=10)

How Agents Should Loop

Start with synorb-catalog, read synorb-details for the best filters, then pull with synorb-manifests. If the result count is low, follow diagnostics.retry_guidance: relax significance, add adjacent Streams, broaden home_domains, or remove narrow tag filters. If the result count is too broad, add tag_names, media_format, source_channel_ids, or a tighter date range.

Key Features

Compact Mode

Manifest tools return headlines + summaries by default. Set compact=False when the agent needs full bodies, key insights, and quotes.

Significance Filter

Use significance='high' for precision. Relax it to medium or remove it when the diagnostics say the result set is thin.

Tag/Topic Filtering

Pass human-readable tag_names directly to Core synorb-manifests. Use Advanced synorb-tags only when you need to inspect exact canonical tags or IDs.

Advanced MCP Discovery Tools

Use the Advanced server when you need direct low-level control. For most work, prefer the Core loop above.

synorb-streams

Advanced catalog alias for explicit stream browsing. Prefer synorb-catalog for agent workflows.

"Find podcast streams" — synorb-streams(media_format='audio')

Advanced MCP Stream Content Tools

Fetch narrow content from a specific Stream. These remain available on the Advanced server for specialized workflows, while Core synorb-manifests is the primary retrieval surface.

synorb-signals

Structured claims — atomic assertions with confidence and evidence tags. Best for data extraction.

synorb-briefs

Editorial narratives with key insights, notable quotes, and actionable takeaways. Best for most LLM tasks.

synorb-multi-stream

Advanced legacy multi-Stream story search. Prefer synorb-manifests for primary Manifest pulls.

synorb-records

Raw source content (full article text, transcripts). Enterprise only.

synorb-manifests

Primary retrieval surface: complete triplets across one or more Streams with diagnostics and retry guidance.

synorb-stream-info

Advanced single-Stream detail alias. Prefer synorb-details when selecting filters across a candidate set.

synorb-account

Plan, quota usage, and available endpoints.

synorb-digests

List your digests — curated bundles of streams with AND/OR filtering.

synorb-digest-manifests

Content from a digest across all its streams. Supports tag_ids filtering.

Sync Ontology Tools

Search entities and topics, manage syncs, create labels.

synorb-tags

Search all 5 tag types: person, organization, place, topic, data. Unified search with fuzzy matching.

synorb-sync

Map a Synorb entity to your internal ID. All delivery payloads include your identifier. This is not a Stream subscription.

synorb-unsync

Remove a sync.

synorb-syncs

List internal-ID mappings with resolved names. This is not Stream inventory or access.

synorb-label

Create a label for organizing syncs (buy-side, portfolio, watchlist).

synorb-labels

List your custom labels.

Help & Workflow Tools

Data Model

Signals

Atomic claims extracted from content. 15-50 per record. Each has a type, confidence level, and evidence classification.

Types: publication announcement disclosure remarks data analysis event

Confidence: stated implied inferred measured

Evidence: direct_quote paraphrase derived observed

Featured claims are linked to brief key points via key_point_index.

Briefs

Structured narratives for reasoning systems delivering information to human operators. Headline, summary, body, sentiment, significance score, and reading time.

Records

Source content with full provenance — source URL, publication date, author, content type, and metadata. Enterprise plans only.

Source Types

Every source is classified as one of three types:

person — an individual (founder, researcher, executive).

organization — a company, publication, government body, or institution.

data — a statistical or data feed (indices, filings, datasets).

Media Formats

Every record carries a media format describing the original medium:

text — articles, blog posts, essays, reports, press releases, white papers.

audio — podcasts, earnings calls, conference talks, radio interviews.

video — YouTube, keynotes, TV interviews, webinars, demos.

social — tweets/X posts, threads, short-form social content.

data — statistical releases, datasets, indices, API data feeds.

Source Channels

Each stream is fed by one or more source channels. A source channel represents a specific content feed — e.g. "OpenAI Blog", "Federal Reserve Bank of St. Louis", "Jim Fan on X".

Every manifest includes source_channel_ids (list) and source_channel_display in the source object. Use source_channel_ids as a query parameter to filter manifests by channel.

Streams

Filtered views over content. Three types:

Discovery — structured summaries from web content (news, blogs, reports).

Narrative — machine-written narratives from numerical and statistical data.

Research — analysis reports written for machine consumption.

Domains

Every stream has one home domain and three cross-domains. 12 canonical domains:

arts-culture-entertainment
economics-business-work
engineering-technology
everyday-life-practical-knowledge
health-medicine
people-biography-history
language-literature
life-environment
physical-sciences-mathematics
places-geography
society-law-government
universe-earth

Synorb Digests Included at no additional charge on Enterprise

Pre-curated intelligence bundles built by Synorb. Each digest groups streams around a theme and is included with Enterprise plans. Different from the Digest Builder, which lets you build your own on Startup | Enterprise plans.

1. Browse the catalog

The public catalog is open — no auth required.

GET /api/digests → { "digests": [ { "name": "Federal Reserve Watch", "slug": "federal-reserve-watch", "stream_count": 12, "manifests_last30d": 72 } ]}

2. Add (Enterprise included)

Enterprise plans can add Synorb Digests directly. No billing, no clones — the canonical digest is shared read-only. Changes flow through automatically.

POST /digests/synorb/{id}/add → { "status": "added", "digest_id": 5 } # Remove DELETE /digests/synorb/{id}/remove → { "status": "removed", "digest_id": 5 } # List added Synorb Digests GET /digests/synorb → { "digests": [{ "digest_type": "synorb", "access_type": "included" }] }

3. Fetch manifests

Once added, pull manifests via REST API or MCP — same signal + brief structure as stream manifests.

# REST API GET /digests/{id}/manifests?published_date_from=2026-03-01&published_date_to=2026-03-09 → Same manifest structure: source + signal + brief (record at Enterprise). # MCP synorb-digests List your added digests synorb-digest-manifests Fetch manifests from a digest
