# Sprint 137 Plan: Multi-Binary MCP Runtime Selection and Health Checks
|
||
|
|
|
||
|
|
## Context
|
||
|
|
|
||
|
|
Workspaces may expose multiple MCP binaries (stable/dev/custom). Sprint 137 adds
|
||
|
|
deterministic runtime selection and health checks to avoid accidental mismatch.
|
||
|
|

|
## Goals
|
||
|
|
|
||
|
|
1. Model selectable MCP runtime targets with explicit precedence
|
||
|
|
2. Add deterministic runtime health probes and compatibility checks
|
||
|
|
3. Prevent silent fallback to incompatible binaries
|
||
|
|
4. Export runtime selection decisions for automation transparency

## Steps
|
||
|
|
|
||
|
|
### Step 1609: MCP runtime target descriptor schema (10 tests)
|
||
|
|
### Step 1610: Runtime selection policy model (10 tests)
|
||
|
|
### Step 1611: Runtime health probe runner (10 tests)
|
||
|
|
### Step 1612: Runtime compatibility checker model (10 tests)
|
||
|
|
### Step 1613: `whetstone_list_mcp_runtimes` MCP tool (8 tests)
|
||
|
|
### Step 1614: `whetstone_select_mcp_runtime` MCP tool (8 tests)
|
||
|
|
### Step 1615: `whetstone_probe_mcp_runtime_health` MCP tool (8 tests)
|
||
|
|
### Step 1616: Runtime selection decision packet model (8 tests)
|
||
|
|
### Step 1617: Runtime selection report artifact (8 tests)
|
||
|
|
### Step 1618: Sprint 137 integration summary + regression (8 tests)

## Architecture Gate
|
||
|
|
|
||
|
|
- Runtime selection must be deterministic under identical inputs
|
||
|
|
- Health probes must return structured failure classes
|
||
|
|
- Compatibility checks must include explicit version/fingerprint evidence
|
||
|
