Mesh
Mesh is an open-source MCP control plane that routes all MCP traffic through a single governed endpoint, providing RBAC, OAuth 2.1, credential vaulting, OpenTelemetry observability, and multi-tenant workspace isolation for teams managing multiple MCP servers.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Service mesh / multi-agent coordination MCP. Controls agent communication paths. Security critical — mesh intercepts all agent communications. mTLS between services recommended.
⚡ Reliability
Best When
You need enterprise-grade governance over MCP tool access: fine-grained permissions, audit logs, credential vaulting, and observability across multiple teams and servers.
Avoid When
Your needs are simple (one server, one user, no compliance requirements), or you cannot self-host and need a managed SaaS gateway.
Use Cases
- • Enterprise teams consolidating many MCP servers behind a single audited, access-controlled endpoint for AI clients
- • Agencies deploying client projects that each need isolated MCP toolsets with independent credentials and audit logs
- • Organizations requiring full OpenTelemetry tracing and RBAC over AI agent tool access without building a custom gateway
Not For
- • Individual developers needing simple tool access without governance overhead
- • SaaS products built on top of Mesh (requires commercial license under SUL)
- • Teams without Bun or Node.js operational experience for self-hosting
Interface
Authentication
Better Auth framework providing OAuth 2.1 with fine-grained permissions per workspace/project. API key management with RBAC. Credential vault for secure token storage.
Pricing
Sustainable Use License (SUL). Contact contact@decocms.com for commercial licensing.
Agent Metadata
Known Gotchas
- ⚠ SUL licensing means commercial users must obtain a paid license before building revenue-generating products on Mesh
- ⚠ OAuth 2.1 setup complexity may be a barrier for small teams accustomed to simple API key auth
- ⚠ Multi-tenancy workspace configuration requires upfront planning; changing workspace structure post-deployment is non-trivial
- ⚠ Virtual MCP strategies (full-context, smart selection) need tuning per use case to optimize token consumption
