- [attention](https://docs.opennous.cloud/mcp/tools/attention.md): What needs your attention across the workspace right now — accounts gone quiet, key facts decayed. Each item ships with a suggested action.

- [get_context](https://docs.opennous.cloud/mcp/tools/get-context.md): Engineered context for one task about one entity. The headline call before drafting outreach, prepping a meeting, or making any decision about a person or company.
- [get_gtm_profile](https://docs.opennous.cloud/mcp/tools/get-gtm-profile.md): The user's own GTM profile — ICP, market, product, pricing, competitors, positioning. Workspace-level, NOT per-entity.
- [query](https://docs.opennous.cloud/mcp/tools/query.md): Retrieve and summarise a corpus of activity across many people. The graph retrieves; your agent finds the pattern.
- [record](https://docs.opennous.cloud/mcp/tools/record.md): Record what happened or what you learned. You observe — Nous derives the updated facts. The only write verb.
- [save_note](https://docs.opennous.cloud/mcp/tools/save-note.md): Keep a meeting brief, transcript, prep, or plain note on a contact's record — append-only and dated, so a contact builds a history across meetings.

- [update_gtm_profile](https://docs.opennous.cloud/mcp/tools/update-gtm-profile.md): Write back a lasting change to a section of the user's own GTM context — the section evolves and the prior version is kept as history, never silently contradicted.

- [Get Context](https://docs.opennous.cloud/public-api/context.md): Engineered context for one task about one entity. The ranked, claim-tagged block your agent consumes before acting.
- [Dedup](https://docs.opennous.cloud/public-api/dedup.md): Cross-list cold-outbound dedup. Classify identifiers as net_new / engaged / bounced / unsubscribed BEFORE you spend.

- [REST API](https://docs.opennous.cloud/public-api/introduction.md): The deterministic surface for workflow runtimes. Call it from n8n, Make, Zapier, or any backend. Parameters are known up front; responses are stable rows.
- [Bulk Create Leads](https://docs.opennous.cloud/public-api/leads/bulk.md): Add up to 1000 leads to a list in a single call. Same dedup behaviour as single create.
- [Create Lead](https://docs.opennous.cloud/public-api/leads/create.md): Add a single row to a lead list. Workspace-wide dedup on email and normalised LinkedIn URL is on by default.

- [Update Lead](https://docs.opennous.cloud/public-api/leads/update.md): Patch a lead row mid-workflow. The morning-loop fix — record sent_at the instant you fire the email so the next iteration's filter excludes the row.
- [Save a Note](https://docs.opennous.cloud/public-api/notes.md): Attach a meeting brief, transcript, prep, or plain note to a contact's record. Append-only and dated, so a contact builds a history across meetings.

- [Create Person](https://docs.opennous.cloud/public-api/people/create.md): Create or upsert a person by identifier. Idempotent — if an entity with one of the identifiers already exists, you get it back with any new claim values asserted onto it.
- [List People](https://docs.opennous.cloud/public-api/people/list.md): Filtered, paginated list of people in the workspace. Workflow shape — same projection your agent sees through /v2/accounts/:id.
- [Update Person](https://docs.opennous.cloud/public-api/people/update.md): Assert claim values directly on a person. Asserted claims are sticky — the derivation engine will not overwrite them from later observations.
- [Query](https://docs.opennous.cloud/public-api/query.md): Retrieve + summarise observations across many entities. Three powers — group by entity, subtract a set, roll up by value — answer 'hottest leads', 'no reply in 5d', 'funnel by stage' without new endpoints.
- [Events Reference](https://docs.opennous.cloud/public-api/triggers/events.md): Every event you can subscribe to, with a sample payload.
- [Triggers](https://docs.opennous.cloud/public-api/triggers/introduction.md): Outbound webhooks. Nous POSTs to your URL the moment a tracked interaction happens, so your workflow runs without polling and without a webhook subscription on the upstream tool.
- [Verify](https://docs.opennous.cloud/public-api/verify.md): Re-check one claim against current observations. The calibration check before any high-stakes action.
