arrca-graph vs mcp-context-forge
arrca-graph: This project provides a live Kubernetes service dependency graph, or service map, built from OpenTelemetry traces and the Kubernetes API. It allows users and LLMs to query service relationships, understand cluster structure, and analyze dependencies for tasks like safe deprecation and blast radius assessment.; mcp-context-forge: ContextForge MCP Gateway is a feature-rich gateway and proxy that unifies diverse AI services including REST, MCP, and Agent-to-Agent (A2A) protocols into a single, clean endpoint. It offers advanced features like federation, virtual servers, robust authentication, rate-limiting, and comprehensive OpenTelemetry observability.

TL;DR
arrca-graphObservability · ★ 13
Safely deprecating services by identifying all callers of specific API versions.
mcp-context-forgeObservability · ★ 4.7k
When to choose:
- You need one gateway in front of MCP servers, A2A agents and REST or gRPC services, with federation and virtual servers.
- You want to wrap REST or gRPC services as MCP tools so MCP clients can use non-MCP backends.
- You need multi-tenancy with RBAC, rate limiting, OpenTelemetry tracing and an admin UI, deployed by PyPI, Docker, Compose or Helm.
When to skip:
- You want a small tool: it is broad infrastructure (gateway, registry, proxy, admin UI, multi-tenancy) that you must deploy, secure and operate.
- You are upgrading from before v0.7.0: the README requires following a migration guide.
- You want to find setup steps quickly: the README is over 160,000 characters.

Features
arrca-graph01Dynamically builds a relationship graph (service map) from Kubernetes API and OpenTelemetry trace spans.
02Functions without requiring service mesh sidecars or direct kernel access.
03Stores a lightweight, distilled relationship graph optimized for querying by scripts and LLMs, unlike raw trace storage.
04Provides query capabilities via REST API and a Multimodal Conversational Platform (MCP) server for LLM interaction.
mcp-context-forge01Unified Endpoint for diverse AI services (MCP, REST, A2A)
02Federation and Virtualization of APIs (REST/gRPC to MCP)
03Comprehensive Admin UI for management and monitoring
04Robust Authentication, Rate-limiting, and Retries
05Advanced OpenTelemetry Observability

Use Cases
arrca-graph↳Safely deprecating services by identifying all callers of specific API versions.
↳Assessing the blast radius of changes by determining upstream dependencies of a deployment.
↳Identifying unused APIs or dead code by finding exposed endpoints with no callers.
↳Understanding data-store reach by pinpointing services that interact with a specific database.
↳Analyzing cross-zone traffic patterns for services.
mcp-context-forge↳Consolidating various AI models and services (REST, MCP, A2A) behind a single API gateway for client access.
↳Integrating legacy REST or gRPC APIs into an MCP-compliant ecosystem without rewriting them.
↳Deploying a scalable and observable AI gateway in multi-cluster environments, with built-in security and traffic management.
