+# PRD: FU-P12-T1-1 — Remove or document `MCPInitializeParams` in schemas
+
+**Created:** 2026-02-18
+**Priority:** P3
+**Branch:** `codex/feature/FU-P12-T1-1-remove-or-document-mcpinitializeparams`
+**Status:** PLAN
+
+---
+
+## 1. Problem Statement
+
+`MCPInitializeParams` exists in `src/mcpbridge_wrapper/schemas.py` but has no
+usage in runtime code or tests. This creates unnecessary schema surface and can
+mislead future maintainers into thinking there is a dedicated initialize-params
+model contract in active use.
+
+---
+
+## 2. Scope
+
+### In Scope
+- Remove `MCPInitializeParams` if it is unused and not required for compatibility.
+- Ensure existing request parsing (`MCPParams.clientInfo`) remains unchanged.
+- Run full project quality gates and capture results.
+
+### Out of Scope
+- Any behavior changes to initialize request handling.
+- Broader schema refactors unrelated to this unused model.
+
+---
+
+## 3. Deliverables
+
+1. `src/mcpbridge_wrapper/schemas.py`
+- Remove the unused `MCPInitializeParams` model and related dead comments.
+
+2. Validation evidence
+- Search evidence confirming no remaining references.
+- Full quality gate results in validation report.
+
+3. `SPECS/INPROGRESS/FU-P12-T1-1_Validation_Report.md`
+- Record pass/fail outcomes for required checks.
+
+---
+
+## 4. Acceptance Criteria
+
+- [ ] `MCPInitializeParams` is removed or has a clear, tested usage.
+- [ ] `pytest` passes.
+- [ ] `ruff check src/` passes.
+- [ ] `mypy src/` passes.
+- [ ] `pytest --cov` reports coverage >= 90%.
+
+---
+
+## 5. Dependencies
+
+- P12-T1 ✅
+
+---
+
+## 6. Risks and Mitigations
+
+- **Risk:** Hidden imports of `MCPInitializeParams` outside obvious call sites.
+  - **Mitigation:** Run repository-wide search and full test/type/lint gates.
+
+---
+
+## 7. Validation Plan
+
+1. Remove model definition from `schemas.py`.
+2. Confirm no references remain with `rg "MCPInitializeParams"`.
+3. Run required quality gates and record outcomes.
+
+
+---
+**Archived:** 2026-02-18
+**Verdict:** PASS

+# Validation Report — FU-P12-T1-1
+
+**Task:** FU-P12-T1-1 — Remove or document `MCPInitializeParams` in schemas  
+**Date:** 2026-02-18  
+**Verdict:** PASS
+
+## Scope
+
+- Removed unused `MCPInitializeParams` model from
+  `src/mcpbridge_wrapper/schemas.py`.
+- Verified runtime/test code has no remaining symbol references.
+
+## Evidence
+
+- Reference scan:
+  - `rg -n "MCPInitializeParams" src tests`
+  - Result: no matches.
+
+## Required Quality Gates
+
+- `pytest`
+  - Result: **PASS** (`582 passed, 5 skipped, 2 warnings`)
+- `ruff check src/`
+  - Result: **PASS** (`All checks passed!`)
+- `mypy src/`
+  - Result: **PASS** (`Success: no issues found in 18 source files`)
+- `pytest --cov`
+  - Result: **PASS** (`582 passed, 5 skipped, 2 warnings`; total coverage **92.18%**, threshold 90%)
+
+## Acceptance Criteria Status
+
+- [x] `MCPInitializeParams` is either removed or has a clear, tested usage.
+- [x] `pytest` suite remains green.
+
+## Notes
+
+- Existing third-party deprecation warnings from `websockets`/`uvicorn` were observed during tests and are unrelated to this task.

+## REVIEW REPORT — FU-P12-T1-1 MCPInitializeParams cleanup
+
+**Scope:** origin/main..HEAD
+**Files:** 6
+
+### Summary Verdict
+- [x] Approve
+- [ ] Approve with comments
+- [ ] Request changes
+- [ ] Block
+
+### Critical Issues
+- None.
+
+### Secondary Issues
+- None.
+
+### Architectural Notes
+- Removing unused `MCPInitializeParams` reduces schema surface area without
+  changing initialize-handshake behavior (`MCPParams.clientInfo` remains the
+  active contract).
+- Archive bookkeeping and task-tracking updates are consistent with current
+  FLOW conventions.
+
+### Tests
+- Full quality gates were executed during EXECUTE:
+  - `pytest` (582 passed, 5 skipped)
+  - `ruff check src/` (pass)
+  - `mypy src/` (pass)
+  - `pytest --cov` (92.18%, threshold 90%)
+
+### Next Steps
+- No actionable findings.
+- FOLLOW-UP step is skipped per FLOW rules.

+- **Status:** ✅ Completed (2026-02-18)
 - **Description:** `MCPInitializeParams` was added to `schemas.py` during P12-T1 but is not used anywhere in the codebase — `MCPParams.clientInfo` covers the same purpose. Either remove it to reduce confusion, or add a usage (e.g., a helper or test) that justifies its existence as a public export.

 - **Parallelizable:** yes
 - **Outputs/Artifacts:**
   - Updated `src/mcpbridge_wrapper/schemas.py` — `MCPInitializeParams` removed or documented with usage
 - **Acceptance Criteria:**
-  - [ ] `MCPInitializeParams` is either removed or has a clear, tested usage
-  - [ ] `pytest` suite remains green
