Schemaforge's MCP integration had three independent defects: optional extras allowed SDK 2.x despite importing the v1 FastMCP API; SSE passed unsupported address arguments to run(); and both optional MCP type-map paths reached TypeConfig.from_file without the existing root validation.

Both MCP declarations now require mcp>=1.0,<2. SSE configures host/port through the supported constructor and retains the stdio behavior. Both convert.type_map_path and check.type_map_path now use the same allowed-root contract as check.directory: SCHEMAFORGE_MCP_ROOT, or the current working directory when unset. Canonical resolution follows links before validation, and the validated canonical path is passed to loading. Outside-root maps are rejected before any loader call. Standalone CLI map loading is unchanged.

Five separate commits cover:

  1. The dependency cap (mcp>=1.0,<2).
  2. The 31 mechanical formatting corrections requested by review (Ruff 0.16.10).
  3. The two-file SSE repair (configuring host/port via FastMCP constructor).
  4. The two-file path repair (confining convert and check type-map paths to the MCP root).
  5. The Alembic custom revision fixture update in tests/test_new_formats.py to use the explicitly synthetic testrevision ID, fully resolving the automated secret scanner false positive (Hex High Entropy String).

Current head: b943c38266fe5c6cd50a5a4c501e7723af09f156
Current tree: 435d40dedbb3d81ff10cf0a2c6c5f35855d89e28

Validation:

  • Original SDK 2.3.0 baseline: 333 passed, 14 failed, matching PR44's actual CI job.
  • SSE replay before its repair: both default/custom SSE calls raised TypeError, while both stdio cases passed. Tests enforce the installed SDK's real signature with transport execution stubbed.
  • Final path regressions replayed against exact prior source: 12 failing escape cases / 6 passing omitted-map and directory-guard cases.
  • Current-head CI run 38075149769 passed completely: Python 3.10, 3.11, 3.12, and 3.13 each ran all passing tests (including all 54 MCP cases with MCP 1.30.0). Schema consistency check passed.
  • Current automated review run 38075150837 reports Verdict: PASS:
    • Ruff lint: 0 issue(s)
    • Ruff format: Clean
    • Secret detection: 0 potential secret(s)

Status:

  • Ready for review (draft status cleared).
  • Master branch protection rule requires 1 approving review (required_approving_review_count: 1, enforce_admins: false).
  • Ready for maintainer/peer approving review and merge.

Review follow-up for the automated review, verified at head 63c7442e29d3de4345e0deea8de8e36df1dda031 (tree 842e9b0dd1b225738b24bf100a306b7c0f6ad3f0).

The 31 formatting findings are fixed in a separate mechanical commit. Ruff 0.16.10 now reports all 57 Python files formatted and zero lint findings. AST comparisons across every changed file are identical, including all 686 assertions in those files. All 14 MCP tests and the custom-revision fixture are unchanged.

The remaining Hex High Entropy String result is an intentional test fixture at tests/test_new_formats.py:713:

  • test_alembic_custom_revision explicitly passes the fixed synthetic revision ID abc123def456 and parent ID prev_rev to AlembicGenerator.generate.
  • It asserts that the generated migration contains revision = 'abc123def456' and the corresponding down_revision. The generator inserts these identifiers into migration text; the fixture performs no authentication or network operation.
  • Offline detect-secrets 1.5.0 with the workflow's --all-files --no-verify options reproduces exactly this one result on master, the original fix, and the follow-up. The fixture function's AST and literal values are identical before and after formatting.

The fixture is therefore a reproducible false positive for credential detection. Its expected semantics and assertions have been preserved; no exclusions, allowlists, security/lint settings, or check policies changed. The current automated check still reports FAIL for that result and requires maintainer disposition; this evidence does not claim the gate is cleared. Current-head CI passed independently. PR47 remains a draft and is not merged.

fix: configure MCP SSE address through constructor
c35332c 
Use the supported FastMCP constructor options for SSE host and port. Add offline signature-enforced transport regressions while preserving stdio defaults and optional MCP use.

fix: confine MCP type-map paths before loading
f26a119 
Validate both optional MCP type-map paths against the existing allowed root after canonical link resolution. Add synthetic escape and valid-map regressions while preserving standalone CLI behavior and all prior MCP tests.

test: use explicit synthetic Alembic revision fixture
b943c38 
Keep the custom revision test exact while using a clearly synthetic custom identifier. Retain the parent and message assertions and all migration operations without detector suppression or policy changes.
