# Phase 33: Fix mcp-tester failure with v1.12.0 - Context

**Gathered:** 2026-03-04
**Status:** Ready for planning

<domain>
## Phase Boundary

Fix mcp-tester 0.2.1 compilation failure against pmcp 1.12.0 caused by `#[non_exhaustive]` struct literals. Bump versions and publish so `cargo install cargo-pmcp` works without `--locked`.

</domain>

<decisions>
## Implementation Decisions

### Code Migration (ALREADY DONE)
- Struct literal sites in `tester.rs` already migrated to `::new()` constructors (commits 97200c1, 5e01f3c)
- No additional code changes needed

### Version Bumps
- mcp-tester: 0.2.1 -> 0.2.2
- cargo-pmcp: bump mcp-tester dependency to 0.2.2
- cargo-pmcp: patch version bump for release

### Publish Order
- Publish mcp-tester 0.2.2 first (cargo-pmcp depends on it)
- Then publish cargo-pmcp patch

### Claude's Discretion
- Exact cargo-pmcp version number (patch bump)
- Whether to include any other pending fixes in the mcp-tester bump

</decisions>

<specifics>
## Specific Ideas

Issue fully specifies the fix: replace struct literals with `::new()` constructors for 5 Result types across 8 construction sites. Code changes already committed.

## Existing Code Insights

### Current State
- `crates/mcp-tester/Cargo.toml`: version = "0.2.1", depends on pmcp 1.12.0
- `cargo-pmcp/Cargo.toml`: depends on mcp-tester 0.2.1
- All struct literal sites in `tester.rs` already use `::new()` constructors

### Integration Points
- mcp-tester is a crates.io dependency of cargo-pmcp
- cargo-pmcp is installed via `cargo install cargo-pmcp`
