mcp-kit
mcp-kit is a Go-based toolkit that provides an MCP server and MCP client implementation (using github.com/shaharia-lab/goai/mcp), plus an HTTP API server layer that exposes REST endpoints and orchestrates requests between a frontend, the MCP client, and LLM providers. It also includes monitoring/observability via Prometheus/Grafana/Loki/Promtail and provides an OpenAPI schema file (openapi.yaml) for the API server.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
README suggests HTTPS/TLS is expected for deployments but does not explicitly state enforcement. Auth appears to be OAuth/OIDC-style via AUTH_* configuration, but there is no documented scope model/least-privilege and endpoint authorization requirements are not clear. Secrets are provided via environment variables (good practice), but there is no explicit statement about logging/redaction. Dependency hygiene cannot be confirmed from the provided content.
⚡ Reliability
Best When
You want a self-hosted MCP stack in Go with an HTTP gateway and SSE-based event streaming, and you can provide/maintain the configuration and downstream LLM/service credentials.
Avoid When
You need a turnkey managed service with guaranteed uptime/support, or you require explicitly documented rate limits, error-code semantics, or idempotency/retry contracts at the API level.
Use Cases
- • Stand up an MCP server in Go to expose tool/resource capabilities over the Model Context Protocol
- • Build an MCP client that connects applications to an MCP server and streams events (SSE)
- • Create an HTTP-facing gateway that turns frontend requests into MCP client calls and optional LLM responses
- • Rapid prototyping/testing of MCP workflows using the included frontend project
- • Deploy basic observability for the MCP API/servers via Prometheus/Loki
Not For
- • Production deployments requiring well-specified operational guarantees (SLA, explicit retry/idempotency semantics) without additional review
- • Environments that require strict, documented data residency/compliance controls from the toolkit itself
- • Teams needing first-class, strongly documented SDKs beyond the Go ecosystem
Interface
Authentication
README indicates an auth setup via AUTH_* configuration (suggesting OAuth/OIDC-style flow), but does not document scopes/granularity or which endpoints require which auth. Upstream LLM/API keys are provided via environment variables.
Pricing
Self-hosted open-source toolkit (MIT). Costs depend on infrastructure and any external LLM providers configured via environment variables.
Agent Metadata
Known Gotchas
- ⚠ SSE/event-stream handling: agents must be prepared to consume streaming responses from the MCP server via the client/API layer
- ⚠ Auth requirements and endpoint-level permissions are not fully specified in the README; misconfigured AUTH_* variables may lead to opaque failures
- ⚠ Rate limits are not documented in the provided README; agents may need conservative request pacing
- ⚠ No documented idempotency/retry semantics are provided; replays may cause duplicate downstream calls depending on implementation
