MCP Worker Test Specification

MCP Worker Test Specification

Working-tree coverage supplement — 2026-10-19

The preserved catalogue below is complete for its cited revision, not for the current working tree. Static TypeScript AST inspection now finds 131 named declarations (129 previously catalogued). Parameterized declarations count once; these are not runtime test counts. Existing stable IDs, assertion excerpts and immutable source links are retained. Some previously catalogued test bodies also changed; use current source before reproducing a case.

The following additional source declarations were inspected without importing or running tests. Their titles identify test intent; expected behavior must be checked against their assertions and the current Worker handlers.

See the current Worker reference and audit methodology. No earlier clean-tree statement below describes the audit’s current dirty working tree.

A. Metadata

No application tests, deployment checks or operator scripts were executed for this review. Not run describes this review, not historical results. Existing reserved IDs have been populated, not removed. Source links identify the inspected revision. Plain-English descriptions retain exact technical names where needed to reproduce a case.

B. Purpose and scope

MCP tool discovery, OAuth permissions, validated tool inputs/results, safe write recovery and queue acknowledgement. The public MCP endpoint is /mcp; tool errors must not be confused with HTTP status codes.

The original cases are a curated high-value review. The catalogue below accounts for all 129 named declarations across 10 test files at this revision; this is not complete behavioural coverage. Requirements come from the cited code or contract; existing tests support only what their assertions check. Related wiki protocol/data pages remain reference destinations, not independent implementation evidence.

Responsibilities, related interfaces and dependencies are identified per case. Production credentials, live deployment behaviour and unsupported performance targets are outside scope. Desired requirements and unresolved guarantees are explicitly distinguished from implemented expectations.

Priority describes review risk: Critical protects access or durable state; High protects a core contract or recovery path; Medium covers a narrower operational concern; Low is reserved for low-impact cases. Integration can mean connected handlers/stores under a simulated runtime; it does not necessarily mean live services.

C. Test environment and prerequisites

Harness/resource evidence: test bindings, OAuth/RPC fixture, consumer and route checks, larger local multi-Worker verification script, resource access rules, notification lifecycle; deployment connections.

D. Test inventory

The first table lists curated risk cases; the second lists every source declaration. The views overlap and must not be added as distinct runnable tests. Status means implementation status; execution remains Not run.

Complete automated source inventory

Every named source declaration in the test folders is listed below. These entries overlap with the curated scenarios above: they are not additional runnable tests. A parameterized declaration counts once, regardless of how many cases it registers. Conditional tests are included; all execution results remain Not run.

E. Detailed test cases

Cases follow the reusable test-case template. Additional explicit fields identify category, code path, command, independent statuses, limitations and follow-up. Expectations were not observed by running tests in this review.

MCP-001 — Discover the established tool set through an authorised MCP connection

MCP-002 — Enforce read and write permissions independently

MCP-003 — Retry a lost write connection with the same operation reference

MCP-004 — Reject unknown tool arguments before contacting other services

MCP-005 — Report an uncertain write outcome without leaking access details

MCP-006 — Acknowledge queue items only after the event component accepts them

MCP-007 — Characterise a storage failure partway through initial token issuance

Complete automated source catalogue

Every named source declaration at this revision is documented below, including tests already referenced by curated cases. Catalogue entries have fresh stable IDs after the original IDs. Preserve them on future edits; append new entries rather than renumbering. Category and priority are provisional documentation triage labels.

Expected outcomes below come from actual source assertions. Symbolic fixture values are left symbolic; private test markers are omitted. Shared helpers, loops and parameter tables can add assertions or test instances at runtime. Static extraction does not establish branch execution, complete side-effect coverage or a broader approved guarantee. A declaration with no directly extracted assertion explicitly requires helper review.

F. Test categories

This maps selected cases rather than all source assertions. An unselected category is not automatically absent from the Worker or wider suite.

G. Execution instructions

pnpm test checks packaged protocol and queue configuration then runs Vitest. pnpm check:queue-config checks route/local/consumer configuration only. pnpm typecheck and the workflow’s pnpm exec prettier --check . are separate. The inspected deployment workflow does not invoke the application suite or the repository’s larger integration-readiness script.

Run documented commands from /home/johnny/projects/toastmachine-mcp-worker only in the prepared test environment. None was run here. Commands are defined in package.json; release behaviour is declared in the CI/deploy workflow. Each case names its existing assertions or proposed location.

H. Results and evidence

A passing related test does not establish every associated guarantee. Record command, environment, immutable revision, run date and output evidence before changing an execution result. Source inspection is not execution evidence.

Complete automated source catalogue results

These entries correspond to source declarations, not additional or runtime-expanded tests.

I. Coverage gaps and open questions

• MCP-007 proposes a partial failure between access-token and refresh-token KV writes; no matching automated case was located. Required cleanup/compensation is not established.
• Queue acknowledgement tests do not prove delivery to each WebSocket listener or exactly-once notification.
• The initial notification-connection failure is logged without a general retry loop; reconnect and missed-update recovery need dedicated assertions and explicit requirements.
• Read-only permissions do not imply hidden tools: all tools remain discoverable, while invocation permissions are enforced.
• No latency, output-token accuracy, notification catch-up or production availability target was found. Resource-size estimation tests are separate from performance guarantees.

Known flaky tests and historical failure rates: Unknown; execution history was not assessed. No new reproduced application defect is claimed. Follow-up ownership and execution dates remain unassigned. Characterization proposals may expose a requirement decision without establishing a stronger approved guarantee.
