MCP Bridge by Appfactor features

  • Schema-driven tool generation. Imports OpenAPI, GraphQL, WSDL or .proto schemas and creates fully typed MCP tools automatically.
  • Self-hosted deployment. Runs in a Docker container on any orchestrator (AWS ECS, Azure Container Apps, etc.) with zero SaaS dependencies.
  • Code Mode token optimization. Reduces context window usage by ~98% using three meta-tools instead of hundreds of individual definitions.
  • Enterprise auth & rate limiting. Supports Bearer, Basic, API Key, OAuth2, AWS Cognito SRP and configurable token bucket limits.
  • Observability dashboard. Provides latency, throughput, token usage and error metrics via OpenTelemetry integration.
  • Semantic tool search. Hybrid full-text, fuzzy and optional vector similarity search for quick tool discovery.

Syrin - Static Contract Analysis for MCP Servers features

  • First-class budget enforcement. Set dollar limits per agent; stop, warn or switch models when the budget is exceeded.
  • Budget-aware persistent memory. Four memory types with decay, import-rank and token-cost awareness, persisting across sessions.
  • Isolated sandbox execution. Run LLM-generated Python, Bash or JavaScript in subprocesses with timeouts and no shared state.
  • 72+ lifecycle hooks. Typed events fire on every LLM request, tool call, memory read, sandbox exec, etc., for observability.
  • Built-in guardrails. PII redaction, prompt-injection detection, content filtering, fact verification and output length limits.
  • Multi-agent orchestration. Swarm topologies and recursive sub-agent spawning share budget, memory and observability.
  • Agent identity & signing. Each agent has a cryptographic Ed25519 identity; messages are signed to prevent impersonation.
  • Token-Oriented Object Notation (TOON). Compact schema format reduces token usage on tool calls by ~40%.
