## Quality 73/100 (new)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_activity_log (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_components (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); create_engagement (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 4,519 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 6 of the 7 days needed

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: deps.dev does not know @simonmak-ascent/coso-mcp@0.1.2

- tools: 39, about 4,519 tokens to load them all
- tool set hash: dfbeafe7959f0002fabfe9bc565e4516
- badge: [![protogrid quality](https://protogrid.dev/badge/com.ascent-partners/coso-mcp.svg)](https://protogrid.dev/servers/com.ascent-partners/coso-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (39)

- `add_review_note`: Add a reviewer note to a workpaper.
- `add_scope_item`: Add a significant account/process to the review scope, with its objective category and assertions.
- `aggregate_deficiencies`: Group related deficiencies by control, flag combinations that may aggregate, and report the overall severity.
- `assemble_workpaper`: Assemble a Markdown control-testing workpaper from the control, its risks, population, sample, test results and exceptions.
- `assess_component`: Report coverage indicators for one COSO component, aggregating its principles.
- `assess_principle`: Report data-driven coverage indicators for one COSO principle (controls, risks and deficiencies mapped to it).
- `classify_deficiency`: Classify a control deficiency as deficiency / significant deficiency / material weakness from likelihood × magnitude (escalates for a pervasive control).
- `compute_sample_size`: Recommend a sample size for a control from its frequency, risk and population size, with a documented rationale.
- `create_engagement`: Create a new internal-control review engagement. Returns the engagement id used by all later tools.
- `create_population`: Register the population for a control — either an explicit item list or a declared size. Bounded to 10000 items.
- `framework_integration_check`: Check that all five COSO components have some recorded coverage and that principles are addressed.
- `generate_report`: Generate a Markdown internal-control review report: scope, risks, controls, testing, workpapers, deficiencies and COSO coverage.
- `get_activity_log`: Return the append-only activity log for an engagement, plus a Markdown rendering.
- `get_audit_log`: Return the append-only audit events recorded for an engagement.
- `get_component`: Return a single COSO component by id, with its principles.
- `get_engagement`: Return an engagement by id.
- `get_principle`: Return a single COSO principle by framework number or slug, including its paraphrased points of focus.
- `get_server_info`: Return the server identity, the COSO framework it covers, and the mandatory disclaimer.
- `get_workpaper`: Return a workpaper including its rendered Markdown.
- `list_assertions`: List the assertions used to frame control objectives: completeness, existence/occurrence, accuracy, valuation, obligations/rights, presentation/disclosure.
- `list_components`: List the five components of the COSO Internal Control—Integrated Framework (ICIF-2013).
- `list_controls`: List the controls registered for an engagement.
- `list_deficiencies`: List the deficiencies recorded for an engagement.

- `list_principles`: List the 17 principles of the COSO ICIF-2013, optionally filtered to a single component.
- `list_risks`: List the risks registered for an engagement.
- `list_scope_items`: List the scope items for an engagement.
- `list_test_results`: List the test results recorded for an engagement.
- `list_workpapers`: List the workpapers assembled for an engagement.
- `note_exception`: Record an exception identified during testing, with root cause, impact and any compensating control.

- `register_risk`: Register a risk to objectives, with likelihood, assertions, related COSO principles and a fraud flag.
- `resolve_review_note`: Mark a review note resolved on a workpaper.
- `select_sample`: Select a reproducible sample from a population. Seeded (deterministic) for random/systematic/haphazard; targeted takes explicit references. Records the method, seed and references.
- `sign_off`: Record a preparer or reviewer sign-off. Warns (does not block) if the same person prepared and reviewed.
