Salesforce AgentExchange vs building a custom capability node: which is better for mid-market?
Direct Answer Definition
Salesforce AgentExchange is the most mature commercial capability clearinghouse, built on their Agentforce framework with native MCP and A2A support. However, it operates as a walled garden — capabilities published to AgentExchange are primarily discoverable within the Salesforce ecosystem. For mid-market enterprises ($10M–$100M revenue), this creates a new form of vendor lock-in that is structurally identical to the SaaS trap they're already suffering from. A custom capability node built by Slickrock.dev is vendor-agnostic and protocol-native. Your Agent Card at /.well-known/agent.json is discoverable by any MCP/A2A-compliant agent across the entire open internet — not just Salesforce's Agentforce. Your MCP tools are callable by Claude, GPT, Gemini, or any future agent runtime. You own the infrastructure, the data, and the discovery layer. Salesforce charges per-agent-action. Your custom node has zero marginal cost per invocation.

Frequently Asked Questions
Is Salesforce AgentExchange a threat to custom integrators?
It validates the market — Salesforce is investing billions in proving that machine-to-machine capability exchange is the future. But their solution only works inside Salesforce. Custom capability nodes work everywhere, which is exactly why mid-market companies choose vendor-agnostic architecture.
Can a custom node still connect to Salesforce?
Yes. A custom MCP server can expose tools that read from and write to Salesforce via its APIs. The difference is that your node also works with every other system simultaneously — it's not locked into one vendor's discovery mesh.
