## MCP tools (30)

### `memory_search_candidates` (~55 tokens)

Return provenance-bound candidates. Fetch original evidence before concluding.

Input parameters:

- `candidate_backend` (string)
- `mode` (string)
- `query` (string, required)
- `status`
- `top_k` (integer)

### `memory_latest` (~28 tokens)

Return latest non-reference records, ordered by recorded event time.

Input parameters:

- `top_k` (integer)

### `memory_fetch_evidence` (~112 tokens)

Fetch an exact event locator; keep display context outside its reference.

Event-less fetches are registered-file diagnostics only and cannot satisfy
evidence eligibility. Changed-source diagnostics retain the registered
reference even when the current file is shorter than that reference.

Input parameters:

- `allow_mismatched_content` (boolean)
- `context_lines` (integer)
- `end_line`
- `event_id`
- `expected_sha256`
- `path` (string, required)
- `start_line` (integer, required)

### `memory_check_evidence_eligibility` (~87 tokens)

Check exact evidence integrity and count, never semantic claim support.

\``claim_type`` is deliberately required: the gate activates from claim
consequence, so a caller must classify the claim instead of inheriting a
silent inactive default.

Input parameters:

- `claim` (string, required)
- `claim_type` (string, required)
- `evidence`
- `materiality` (string)

### `memory_audit_ledger` (~25 tokens)

Return read-only policy and record-integrity findings for canonical JSONL.

### `public_demo_status` (~21 tokens)

Return a path-free publication receipt for the running MCP process.

### `research_prepare_ingest` (~104 tokens)

Validate input and create an immutable pending draft, never a canonical record.

Each new source registration contains only ``path``, ``source_id``, and
\``source_type``. The path must be project-contained and is hash-bound at
preparation and commit. A canonical human approval record must already
exist and cover this record's study and kind.

Input parameters:

- `approval_ref` (string, required)
- `record` (object, required)
- `source_registrations`

### `research_commit_ingest` (~116 tokens)

Append exactly one approved pending draft and refresh derived indexes.

This is a mutating, non-idempotent host-approved tool. It accepts no record
body and no model-supplied approval boolean. It refuses a replay, any change
to the canonical ledger or staged source files, or an invalid human scope
approval. Canonical append success is reported separately from derived-index
refresh status.

Input parameters:

- `approval_receipt_id` (string, required)
- `draft_id` (string, required)
- `draft_sha256` (string, required)

### `research_pending_ingest_status` (~31 tokens)

Return metadata for one pending immutable ingest draft without its content.

Input parameters:

- `draft_id` (string, required)

### `codex_host_agent_status` (~46 tokens)

Report whether protected current-task Codex control is available.

Without a host-authenticated per-call thread binding this returns a
structured unavailable result and discloses no thread metadata.

### `codex_prepare_agent_control` (~70 tokens)

Fail closed unless a protected Codex host broker is available.

The tested Codex 0.147.0 stdio MCP contract has no documented or validated
authoritative caller-task binding and proposal-bound user approval receipt.
No proposal or host state is created.

Input parameters:

- `action` (string, required)

### `governance_get_capabilities` (~23 tokens)

Return the fixed governance roster and non-executing host contract.

### `governance_get_role_manifest` (~29 tokens)

Return one immutable registered role manifest and its canonical hash.

Input parameters:

- `agent_id` (string, required)

### `governance_get_role_prompt_contract` (~31 tokens)

Return the internal versioned prompt contract for one registered role.

Input parameters:

- `agent_id` (string, required)

### `governance_validate_task_packet` (~29 tokens)

Validate a proposed agent task without dispatching or approving it.

Input parameters:

- `packet` (object, required)

### `governance_validate_decision` (~34 tokens)

Validate a returned decision against its exact task packet.

Input parameters:

- `decision` (object, required)
- `packet` (object, required)

### `governance_evaluate_gate` (~36 tokens)

Evaluate deterministic claim gates; this never grants user approval.

Input parameters:

- `claim_type` (string)
- `decisions` (array, required)

### `governance_prepare_codex_dispatch` (~38 tokens)

Prepare, but do not execute, a host-owned agent dispatch.

Input parameters:

- `governor_receipt`
- `packet` (object, required)

### `governance_prepare_scope_governor_receipt` (~51 tokens)

Bind a validated passing scope decision to exact governed task hashes.

Input parameters:

- `governed_packets` (array, required)
- `governor_decision` (object, required)
- `governor_packet` (object, required)

### `governance_prepare_codex_critical_batch` (~37 tokens)

Prepare the isolated fixed four-reviewer critical batch.

Input parameters:

- `governor_receipt`
- `packets` (array, required)

### `governance_capture_codex_decision` (~38 tokens)

Validate a host decision without writing it to the canonical ledger.

Input parameters:

- `decision` (object, required)
- `packet` (object, required)

### `governance_assess_plan` (~32 tokens)

Assess necessity, bounded work, elapsed time, difficulty, and cost evidence.

Input parameters:

- `operation` (object, required)

### `governance_evaluate_operation` (~39 tokens)

Evaluate declarative preflight; never authorize or execute a host tool call.

Input parameters:

- `operation` (object, required)
- `packet` (object, required)

### `governance_resolve_failure_policy` (~33 tokens)

Resolve failure handling without accepting an off/unrecorded mode.

Input parameters:

- `profile`
- `task`

### `governance_prepare_failure_record` (~39 tokens)

Prepare the mandatory minimum tombstone; storage remains host-owned.

Input parameters:

- `failure` (object, required)
- `profile`
- `task`

### `research_index_status` (~19 tokens)

Report derived-index health without modifying canonical research records.

### `research_profile_status` (~19 tokens)

Inspect the declared research profile without executing any route.

### `research_semantic_models` (~21 tokens)

List reviewed local SentenceTransformer models without contacting a registry.

### `research_semantic_setup_plan` (~72 tokens)

Plan without network or execution; revision must be a full immutable commit SHA.

Input parameters:

- `auto_refresh` (boolean)
- `device` (string)
- `environment_manager` (string)
- `model_id` (string, required)
- `reuse_existing` (boolean)
- `revision` (string, required)

### `governance_preflight_parallel_batch` (~60 tokens)

Validate a parallel batch without starting agents, models, or network.

Input parameters:

- `aggregate_cost_ceiling_usd` (number, required)
- `declared_costs_usd`
- `max_workers` (integer, required)
- `packets` (array, required)
