The holo platform

Three things. One layer underneath every agent.

Context layer

Connect once. Index everything.

20 connectors, continuous ACL-aware sync. Hybrid retrieval (vector + full-text) over one source of truth every agent reads.

Procedures

Not just search. Callable skills.

Holo learns the procedures your team has proven out and exposes them as MCP-invokable skills. Agents invoke what the company has done before.

Connectors

Holo connects to all your tools.

Plug-and-play, syncs continuously, respects ACLs at ingestion. Every connector is open source and extensible.

See all 20 connectors Build your own

packages/connector-framework

90-line TypeScript interface. Ship a new connector in an afternoon.

BYO

Open source · AGPL-3.0

Self-host. Inspect. Extend.

Deploy holo on your own infrastructure. Read the source. Submit a connector. The community edition ships every primitive — and there is no closed core.

APIs

MCP + REST + OpenAPI.

Same backend, three transports. Every callable tool is reachable from any agent runtime.

Transparent

Benchmarks in the repo.

We publish reproducible numbers, not marketing tiles. Every retrieval call is logged and replayable.

Modular

Connectors are pluggable.

A 90-line interface. 20 connectors today. Ship your own without forking — the kernel stays small.

Self-host guide

Use cases

Start with sales and support.
Extend from there.

Sales enablement

Answer "can our product do this?" in seconds.

AEs and SEs paste the question into Slack or their agent. Holo answers from source code, Linear, prior calls, and the deal record — every answer cited.

Tracesearch → bash cat /github/… → bash cat /pylon/… → draft

Customer support

Drafted replies with the right sources attached.

A new ticket fires a webhook. Holo pulls the customer’s history, matching docs, and prior resolutions — and posts a draft reply for the human to approve.

Tracesearch → bash cat /pylon/… → bash grep -r /notion → draft

Security & compliance

Security questionnaires answered with citations.

Paste the questionnaire into chat. Holo pulls prior answers, architecture docs, and source code as evidence — drafts answers with links to every source.

Tracesearch → bash cat /notion/… → bash cat /github/…/code/… → draft

Everyone else

One search box across every system.

A dashboard search or a Slack /ask hits REST directly. Ranked results across every connector — no agent, no MCP, no LLM in the path.

TracePOST /v1/search → ranked chunks

Observability

See what every agent did.

You handed agents the keys to your CRM and Slack. The dashboard shows what they did with them.

100%

of calls logged & attributable

per agent · per user · per record

Tool traffic

Which procedures get called, by which agent, p50/p95 latency, error rates.

Failed queries

What agents tried to ask but got nothing. Every gap is a candidate for the next procedure.

Audit & replay

Per-call attribution: which agent, which user, which records. Replay any past invocation side-by-side.

Anomaly signals

Spikes, exfiltration shapes, prompt-injection-shaped tool calls — surfaced before they become incidents.

Licensing

The Community Edition is AGPL-3.0 — free to self-host, fork, and modify. Enterprise add-ons (SSO, RBAC, per-call audit log, custom code, whitelabeling) live under ee/ directories and require a paid commercial license for production use. Both editions live in the same repo; the path determines the license.
