Return Envelope (OFE / 1.0)

Open Fact Envelope

Every response adheres to the strict ofe/1.0 envelope schema, returning verified data, typed facts, entity references, and follow-up tool suggestions:

`data` Payload

Lists organic competitor domains ranked by search keyword overlap, average position, and shared keywords.

`coverage` & Freshness

Reports returned count vs total items, observation timestamp as_of, and scope notes. Evaluated live per request.

`resources` (Dataset Exports)

If a query yields high row counts (e.g. >1,000 queries in Search Console), full unpaginated tables are persisted to R2 and linked as an mcpseo:// URI for follow-up retrieval via export_dataset.

`next_actions`

Provides suggested follow-up tool calls with pre-filled arguments so your AI agent can navigate from discovery to detailed inspection autonomously.

LLM Agent Workflow

Claude & Cursor Integration

Step 1

Prompt Trigger

"Who are postman.com's primary SEO competitors?"

Step 2

Agent Decision & Reasoning

The agent queries discover_competitors to extract high-overlap competitor domains, which are then passed directly into compare_keyword_coverage and compare_backlink_gap.

Step 3

Recommended Follow-up Tools
