SynapseCode Architecture

What is SynapseCode?

SynapseCode is an open-source, high-performance AST Code Graph and context optimization engine written in Go. It connects seamlessly to Claude Desktop, Cursor, and AI agents via the Model Context Protocol (MCP) to reduce prompt token consumption by 75% to 95% while eliminating hallucinations.

What's New in v1.2.0

1. Extended Multi-Language & Framework Support (8 Languages)

  • PHP & Laravel: Full support for Eloquent models, controllers, traits, and PHP 8+ attributes (#[Route], #[HttpGet]).
  • Java & Spring Boot: Annotations (@RestController, @Service, @Autowired, @GetMapping), Java records, interfaces, and enums.
  • C# (.NET / ASP.NET Core): Attribute routing, async task methods (Task<T>), records, enums, and interfaces.
  • C & C++: #include resolution, namespaces, classes with multiple inheritance, templates, and structs.
  • Go, TypeScript/JavaScript, Python, and Rust.

2. Okapi BM25 Search Engine & Reciprocal Rank Fusion (RRF)

  • Semantic tokenizer splitting camelCase, PascalCase, snake_case, and acronyms (JSONParser -> ["json", "parser"]).
  • Field-weighted Okapi BM25 lexical scoring with length normalization and suffix stemming.
  • Reciprocal Rank Fusion (RRF) mathematically blending lexical relevance with topological PageRank centrality.

3. Impact Analysis & Blast Radius (get_impact_analysis)

  • Reverse BFS dependency traversal computing direct callers, transitive dependents, affected files, and impacted test suites to verify before refactoring.

4. Persistent Disk Cache & Live File Watcher

  • Sub-20ms incremental startup with SHA-256 integrity cache (.synapse/cache.json).
  • Live event-driven background sync (synapse mcp --watch) using OS kernel hooks (fsnotify).

5. Full Model Context Protocol Implementation

  • 6 Native Tools: get_repo_map, get_context_for_task, get_symbol_callers, get_symbol_definition, get_impact_analysis, get_file_outline.
  • Resources (synapse://graph/...): Virtual file system exploration (summary, languages, symbols, file/{path}, symbol/{name}).
  • Guided Prompts: 1-click contextual workflows (refactor_safe, generate_unit_tests, audit_architecture, explain_symbol).

Quickstart

1. Installation via Go

go install github.com/nosleepman1/SynapseCode/cmd/synapse@latest

2. Claude Desktop Integration (claude_desktop_config.json)

{
  "mcpServers": {
    "synapse-code": {
      "command": "synapse",
      "args": ["mcp", "--path", "/path/to/your/repository", "--watch"]
    }
  }
}

3. CLI Commands

# Search symbols with BM25 + RRF
synapse query "jwt token verification" --path /path/to/repo

# Persist and inspect index
synapse index --path /path/to/repo

# Extract targeted context under token budget
synapse context "fix authentication workflow" --budget 3500
