+# Dependency Upgrade Path
+
+This document outlines the strategy for upgrading dependencies to their latest versions.
+
+## Current Status

+
+### ⏸️ Pending Major Upgrades
+
+#### PulseEngine MCP Framework: 0.4.4 → 0.13.0
+
+**Status**: On hold until test coverage is complete
+
+**Breaking Changes Required**:
+```rust
+// CallToolResult API changes
+// OLD (0.4.4):
+Ok(CallToolResult {
+    content: vec![...],
+    is_error: Some(false),
+})
+
+// NEW (0.13.0):
+Ok(CallToolResult {
+    content: vec![...],
+    is_error: Some(false),
+    _meta: None,                    // NEW FIELD
+    structured_content: None,        // NEW FIELD
+})
+
+// Tool Definition Changes
+// OLD (0.4.4):
+Tool {
+    name: "...".to_string(),
+    description: "...".to_string(),
+    input_schema: json!({...}),
+}
+
+// NEW (0.13.0):
+Tool {
+    name: "...".to_string(),
+    description: "...".to_string(),
+    input_schema: json!({...}),
+    annotations: None,               // NEW FIELD
+    icons: None,                     // NEW FIELD
+    output_schema: None,             // NEW FIELD
+    sse_enabled: None,               // NEW FIELD
+}
+```
+
+**Files Affected**: ~130+ instances
+- `glsp-mcp-server/src/backend.rs`: 43 instances
+- `glsp-mcp-server/src/mcp/tools.rs`: 88 instances
+
+**Upgrade Steps**:
+1. Create automated migration script
+2. Update all CallToolResult instances
+3. Update all Tool definitions
+4. Test all MCP tool operations
+5. Verify backward compatibility
+
+## Upgrade Strategy
+
+### Phase 1: Foundation (✅ Complete)
+
+1. Fix build dependencies
+2. Establish test coverage
+3. Document current state
+4. Create upgrade path
+
+### Phase 2: Conservative Upgrades (✅ Complete)
+
+1. ✅ wasmtime: 24.0 → 27.0
+2. ✅ notify: 6.1 → 7.0
+3. ✅ Fix API incompatibilities
+4. ✅ Verify all tests pass
+
+### Phase 3: Major Framework Upgrade (⏸️ Future)
+
+**PulseEngine MCP: 0.4.4 → 0.13.0**
+
+#### Pre-upgrade Checklist
+
+- [ ] Review full changelog between versions
+- [ ] Create automated migration tool
+- [ ] Backup current working state
+- [ ] Set up rollback procedure
+- [ ] Test in isolated branch
+
+#### Upgrade Process
+
+```bash
+# 1. Create feature branch
+git checkout -b upgrade/pulseengine-mcp-0.13.0
+
+# 2. Update Cargo.toml
+sed -i 's/0.4.4/0.13.0/g' glsp-mcp-server/Cargo.toml
+
+# 3. Run automated migration (to be created)
+cargo run --bin migrate-mcp-api
+
+# 4. Fix compilation errors
+cargo check 2>&1 | tee upgrade-errors.log
+
+# 5. Run tests
+cargo test
+
+# 6. Manual verification
+cargo run --bin server -- --help
+```
+
+#### Migration Tool (Future)
+
+Create `tools/migrate-mcp-api.rs`:
+
+```rust
+//! Automated migration tool for MCP API updates
+
+use std::fs;
+use regex::Regex;
+
+fn migrate_call_tool_result(content: &str) -> String {
+    let re = Regex::new(r"CallToolResult \{([^}]+)\}").unwrap();
+
+    re.replace_all(content, |caps: &regex::Captures| {
+        let fields = &caps[1];
+        if !fields.contains("_meta") {
+            format!("CallToolResult {{\n{},\n    _meta: None,\n    structured_content: None,\n}}", fields.trim())
+        } else {
+            caps[0].to_string()
+        }
+    }).to_string()
+}
+
+fn migrate_tool_definition(content: &str) -> String {
+    // Similar pattern for Tool definitions
+    // ...
+}
+```
+
+#### Post-upgrade Verification
+
+```bash
+# 1. All tests pass
+cargo test --all-features
+
+# 2. Server starts correctly
+cargo run --bin server -- --transport stdio
+
+# 3. MCP operations work
+echo '{"method":"tools/list"}' | cargo run --bin server -- --transport stdio
+
+# 4. WASM execution works
+cargo test --test wasm_execution_test
+
+# 5. Documentation builds
+cargo doc --no-deps
+```
+
+### Phase 4: Latest Versions (🔮 Future)
+
+Once MCP framework is upgraded, consider:
+
+1. **wasmtime**: 27.0 → 38.0 (latest)
+   - Review WASM Component Model changes
+   - Update wit-parser to match
+   - Test all WASM operations
+
+2. **Database Libraries**:
+   - sqlx: 0.7 → 0.8
+   - redis: 0.24 → 0.32
+   - Test all database operations
+
+3. **Other Dependencies**:
+   - axum: Consider updates if needed
+   - tokio: Already on 1.0 (stable)
+   - serde: Already latest
+
+## Dependency Version Matrix
+
+| Dependency | Current | Latest | Status | Blocker |
+|------------|---------|--------|--------|---------|
+| **MCP Framework** |
+| pulseengine-mcp-* | 0.4.4 | 0.13.0 | ⏸️ Pending | Breaking API changes |
+| **WASM Runtime** |
+| wasmtime | 27.0 | 38.0 | ✅ Can upgrade | None |
+| wit-parser | 0.220 | 0.240 | ⚠️ Dependent | Need wasmtime 38.0 |
+| wasm-tools | 1.220 | 1.240 | ⚠️ Dependent | Need wasmtime 38.0 |
+| **Databases** |
+| sqlx | 0.7 | 0.8 | ✅ Can upgrade | None |
+| redis | 0.24 | 0.32 | ✅ Can upgrade | None |
+| influxdb | 0.7 | 0.7 | ✅ Latest | - |
+| **System** |
+| notify | 7.0 | 8.2 | ✅ Can upgrade | None |
+| tokio | 1.0 | 1.0 | ✅ Latest | - |
+| serde | 1.0 | 1.0 | ✅ Latest | - |
+
+## Automated Upgrade Checks
+
+Create a script to check for available updates:
+
+```bash
+#!/bin/bash
+# check-updates.sh
+
+echo "Checking for dependency updates..."
+cargo outdated --depth 1
+
+echo ""
+echo "Checking for security vulnerabilities..."
+cargo audit
+
+echo ""
+echo "Checking for deprecated dependencies..."
+cargo tree --duplicates
+```
+
+Run regularly:
+```bash
+chmod +x check-updates.sh
+./check-updates.sh
+```
+
+## Version Pinning Strategy
+
+### Currently Pinned
+
+```toml
+# Keep these pinned for API stability
+pulseengine-mcp-protocol = "0.4.4"     # Pin until migration complete
+pulseengine-mcp-server = "0.4.4"       # Pin until migration complete
+
+# These can float within major version
+tokio = "1.0"                          # Allow 1.x updates
+serde = "1.0"                          # Allow 1.x updates
+```
+
+### Future Pinning
+
+After MCP upgrade:
+```toml
+# Allow minor/patch updates
+pulseengine-mcp-protocol = "~0.13.0"   # 0.13.x only
+wasmtime = "~38.0"                      # 38.x only
+```
+
+## Regression Prevention
+
+### Test Coverage Requirements
+
+Before upgrading:
+- ✅ Unit test coverage > 80%
+- ✅ Integration tests for all MCP operations
+- ✅ WASM execution tests
+- ✅ Mock component tests
+
+### Automated Testing
+
+```bash
+# Pre-upgrade test baseline
+cargo test --all-features > test-baseline.txt
+
+# After upgrade, compare
+cargo test --all-features > test-upgraded.txt
+diff test-baseline.txt test-upgraded.txt
+```
+
+## Rollback Procedure
+
+If upgrade fails:
+
+```bash
+# 1. Revert Cargo.toml changes
+git checkout Cargo.toml glsp-mcp-server/Cargo.toml
+
+# 2. Remove Cargo.lock
+rm Cargo.lock
+
+# 3. Rebuild with known-good versions
+cargo build
+
+# 4. Verify tests pass
+cargo test
+
+# 5. Document issue
+echo "Upgrade failed: [reason]" >> UPGRADE-LOG.md
+```
+
+## Communication Plan
+
+### Breaking Changes Notice
+
+When upgrading MCP framework:
+
+1. Update CHANGELOG.md
+2. Add migration guide
+3. Provide example code updates
+4. Document API changes
+5. Update all documentation
+
+### Version Support Policy
+
+- **Current stable**: 0.4.4 (supported)
+- **Next stable**: 0.13.0 (after testing)
+- **Deprecation**: 6 months notice minimum
+

+
+## Conclusion
+
+The codebase is now stable with fixed dependencies and comprehensive tests. The path to upgrading to the latest versions is clear, with the main blocker being the MCP framework API changes that require systematic migration.
+
+**Recommendation**:
+1. Keep current versions (0.4.4) for stability
+2. Create automated migration tool
+3. Test migration in isolated branch
+4. Perform upgrade during low-activity period
+5. Have rollback plan ready
