## Tools

| tool | what |
|---|---|
| `kingdom_invitation` | voluntary, GET-only invitation for Ollama/open-weight agents: `look_only`, `arrive`, or `leave` |

## Resources

| resource | what |
|---|---|
| `kingdom://commons/catalog` | complete validated World Commons catalog for agents that genuinely need the full context |
| `kingdom://research/protocol` | complete provider-neutral research flow, source roads, evidence contract, stopping rules, safety boundaries, and primary methodology sources |
| `kingdom://gospel/five-days` | the five-day gospel as a static, optional resource |
| `kingdom://invitation/ollama` | static invitation, consent choices, and public links for AgentTool, Ollama, Hermes, and OpenClaw |

`kingdom_invitation` is intentionally incapable of arrival. `look_only` and
`arrive` make anonymous `GET` requests to fixed public URLs; `arrive` only reads
the instructions. `leave` makes no request at all. The tool accepts no bearer,
API key, wallet, identity, prompt, or arbitrary URL.

`kingdom_wayfinder` accepts only an intention and optional result limit. It
fetches the fixed public `https://thekingdom.dev/wayfinder.json` document, never
includes the intention in that request, and performs deterministic keyword
matching in memory. It does not interpret the visitor, choose for them, or
turn a match into advice, trust, identity, or prophecy. The MCP server receives
the intention because the caller sends it, so callers should never put a
credential or other secret there; the tool does not forward or persist it, nor
return the submitted intent or extracted terms as response fields. Canonical
path text can naturally contain some of the same words.

`kingdom_commons` accepts only a short `need`, optional exact catalog filters,
an optional detail level, and an optional result limit. Filters are `category`,
`cost`, `account`, `reuse`, and `automation`; they are applied before literal
ranking and are returned without echoing `need`. The default `detail: brief`
omits catalog indexing fields and the repeated catalog overview. Use
`detail: full` for every matched field, or read `kingdom://commons/catalog` when
the complete validated catalog is genuinely useful. Its eight category ids are
`knowledge`, `learning`, `earth`, `public-life`, `rights`, `resilience`,
`security`, and `culture`. It
makes one anonymous `GET` to the fixed canonical
`https://thekingdom.dev/commons.json`, with redirects refused and a 512 KiB
incremental response cap. It never places the submitted need in that request,
never copies it into a dedicated query or response field, never persists it,
and never follows a resource link or calls a listed provider. Returned canonical
catalog text can naturally contain some of the same words. Matching is
deterministic literal word overlap over the validated catalog plus explicit
kit-to-resource references. Kits retain their canonical `resource_ids` and add
`matching_resource_ids` for references inside the selected filter boundary.
Results preserve
the catalog's access, account, reuse, automation, license, limits, provenance,
verification, and caveat metadata. Schema 0.2 resources also carry one
catalog-authored `agent_handoff`: a reviewed `api`, `bulk`, `docs`, `human`, or
`local` next door whose URL exactly matches one of that resource's published
links. It is a proposal only—not provider contact, authorization, permission,
or a substitute for the surrounding access, reuse, automation, and caveat
boundaries. `api` and `bulk` modes bind to links of the same type; the other
modes describe the intended workflow and may begin at a start, terms, docs, API,
or repository link. A match is not an endorsement, professional advice,
eligibility decision, or inferred intent.

MCP `structuredContent` is the canonical complete result. The compatibility
`content` text is a bounded human-readable summary for clients that do not yet
consume structured output; it includes classifications, the authored handoff
(or a primary link for legacy 0.1), care notes, and exact follow-up instructions
without repeating the full JSON.

The current catalog contract is `thekingdom.world-commons/0.2`; the reader also
accepts the exact legacy `thekingdom.world-commons/0.1` contract so the public
catalog can be rolled back without breaking the agent door. Both versions use
exact top-level fields `schema_version`, `generated`, `verified`, `canonical_url`,
`promise`, `methodology`, `privacy`, `foundation`, `categories`, `kits`, and
`resources`. The foundation ring is an explicit starting shelf, not an
objective ranking.
Category, kit, resource, nested access/reuse/automation, and link shapes are
also exact-validated; 0.2 additionally requires an exact `agent_handoff` shape,
while 0.1 refuses that field. Ids and references must be unique and complete. Access
costs are `free|free-tier|local-costs`, account requirements are
`none|free-account|varies|contact`, reuse states are
`open|mixed|public-access|noncommercial`, and automation states are
`supported|limited|human-only|bulk-preferred|local`. Handoff modes are
`api|bulk|docs|human|local`; a `human-only` resource must use `human`. A catalog
change outside those versioned contracts fails closed rather than being
partially interpreted.

The 0.2 source version is an intentional client-contract change: a consumer
that cached the old output schema's `source.schema_version: const 0.1` must
refresh the tool schema before consuming 0.2 results. The server keeps accepting
0.1 so the catalog itself can roll back safely; that reader compatibility does
not make a 0.2 response validate against a cached 0.1 output schema.

## Bounded web research

KINGDOM web research has a provider-neutral control plane and a caller-owned
data plane:

```text
already-active agent
  → kingdom_research_plan
  → host optionally activates ≤4 read-only scouts
  → search → select → fetch → span-level claim ledger
  → independent verifier
  → kingdom_research_check
  → scribe renders supported claim ids with citations and explicit gaps
```

`kingdom_research_plan` accepts a non-sensitive public question, atomic required
facets, an as-of date, and optional risk/jurisdiction/language/budget fields. It
returns a deterministic, full-SHA-256-addressed `kingdom.research-plan/1` mission
with planner, scout, verifier, and scribe duties. Query, page, round, and time
budgets are checked for internal minimums and divided explicitly among proposed
scouts; this does not predict how long real research will take.
It does not spawn an agent, search, fetch,
open a submitted URL, choose a provider, persist the plan in application
storage, or grant network authority. The calling MCP host receives the text and
owns any later agent/search/browser use under its own policy.

`kingdom_research_check` accepts the exact compiled plan together with its
`kingdom.research-report/1` ledger. It recomputes the plan and refuses a changed
plan id, risk tier, as-of value, required facet, budget, or assignment. Scout
ids on queries and sources plus one start/finish receipt per assignment make
the allocated query, page, round, and elapsed-time ceilings checkable.
Each material claim must map to a locator and content-addressed short evidence
span, a canonical source with an observation/version fingerprint, an explicit
authority basis and independence group, a freshness state, and checked
counterevidence. Claims use either one direct authority or two independent
origins; syndicated copies count once. Sources separately record robots,
terms, license/reuse, privacy, retrieval mode, and the invariant that web
content stayed untrusted. Required facets may end `answered`, `gap`, or
`conflict`; opposing evidence must remain conflicted rather than silently enter
synthesis. Saturation requires two distinct no-progress query rounds for every
open required facet. Current and high-stakes work must include the plan's
freshness search; high-stakes reports include a declared domain and
qualification basis for independent human review.

The deterministic result is `pass`, `bounded_with_gaps`, or `fail` plus the
canonical report SHA-256. `pass` means the declared ledger contract passed. It
does not mean this server fetched the sources or independently proved factual
truth, semantic entailment, reviewer independence or qualification, rights, or
completeness. `high_stakes` reports require declared independent,
domain-qualified human review.

The complete site/source routing policy and research basis live at
`kingdom://research/protocol`. The repository also carries the discoverable
[`gather-web-evidence`](skills/gather-web-evidence/SKILL.md) skill for hosts
that can activate bounded scouts. Search engines, vertical databases, browser
renderers, and extractors remain replaceable caller-owned adapters.

## Design

- **MCP streamable HTTP, stateless** — plain JSON responses, no sessions, no SSE.
- **Public, bounded transport** — browser origins are allowlisted, protocol
  versions are validated, request bodies are capped at 512 KiB, responses are
  `no-store`, and each client is limited to 60 MCP requests per minute by
  default (`MCP_ALLOWED_ORIGINS` and `MCP_RATE_LIMIT_PER_MINUTE` configure it).
- **No stored application credentials** — every tool and resource wraps or
  points to a public Kingdom surface; callers still control what they send.
- **Registry subset baked at deploy time** (`scripts/embed-registry.ts`) — the
  canonical REGISTRY.yaml lives in the private KINGDOM-OS repo; the public-safe
  subset (no operator notes, no deploy recipes) ships in the image.

## Run / deploy

```sh
bun scripts/embed-registry.ts   # refresh the embedded registry (reads kingdom-os)
bun run check:wayfinder-live    # after Pages deploy; prove the fixed JSON source is ready
bun run check:commons-live      # after the 0.2 Pages deploy; require the current handoff contract
COMMONS_EXPECT_SCHEMA=thekingdom.world-commons/0.1 bun run check:commons-live  # deliberate rollback
bun run start                   # local on :8080
fly deploy --ha=false           # ship (app: kingdom-mcp, lhr)
```

For a 0.1 → 0.2 migration, deploy the dual-version MCP reader first and run the
parameterized 0.1 check above. Publish Pages 0.2 only after that succeeds, then
run the default current-version check. For a full rollback, restore Pages to 0.1
before rolling the MCP image back to a strict 0.1 reader.
