Rayrun

Rayrun's per-tool-call pricing at USD 0.2 per 1,000 calls means agencies can predict delivery costs only if they model client usage before signing retainers. The Free tier's 50,000 monthly tool calls and 25 source-built services let agencies validate multi-tenant MCP deployments at zero vendor cost, then graduate to Team at $25/month per developer when shared credential vaults and client-specific access roles become necessary.

Rayrun collapses credential exposure to a single hosted endpoint: upstream keys live in its vault, and each client receives only a token. The framework asks one question per engagement: how many environments would hold that secret without Rayrun? A salon with one OpenAPI integration has a blast radius of one, so the $1,800 Starter MCP Deploy at 16 hours is a clean fit. A five-client agency running separate MCP servers across Claude, Cursor, VS Code, and Windsurf has a blast radius of five or more, and the Team plan at $25 monthly, with its shared credential vault and client-specific access roles, pays for itself the first time a client rotates a key. Model the radius before quoting: the wider it is, the more of the retainer Rayrun's per-tool-call pricing at USD 0.2 per 1,000 calls can absorb without eroding delivery margin.

The AI agent itself is a commodity, but the value for agencies lies in the integration layer: connecting a pre-built agent to a client's CRM, calendar, and review cycle. This framework shifts focus from selecting the 'best' agent to mastering the wiring process. For example, an agency using Vendasta's white-label AI receptionist for a local business must configure it to match the client's booking rules and follow-up cadence, turning a generic tool into a tailored service. As agentic AI adoption grows (77% of decision-makers now run agents in production), clients expect this customization. Agencies that treat agents as components and invest in repeatable wiring processes can charge retainers for ongoing optimization, rather than one-off setup fees.

The AI agent market sells finished workers, but the strategic value for agencies lies not in the agent itself, which is increasingly a commodity, but in the wiring that connects it to a specific client's CRM, calendar, and review cycle. This framework, 'Wiring Over Widgets,' argues that agencies that treat agents as components rather than products win. The agent is the widget; the wiring is the integration, customization, and ongoing optimization that turns a generic tool into a tailored solution. For example, a white-label platform like Vendasta provides AI employees, but the agency's role is to configure them for each local business's unique lead flow and follow-up process. This wiring is where retainer pricing originates, as it requires ongoing maintenance and adjustment. Recent research shows that 88% of B2B marketers face foundational gaps, meaning clients need help not just deploying agents, but ensuring their operations can support them. Agencies that master the wiring can charge a premium for the irreducible value they add.

Adopt Rayrun when per-client credential isolation and per-tool access policies are contractually required and projected tool calls fit inside the pooled 100,000-per-developer Team allowance; otherwise stay on the free tier until a paying client justifies the $25 seat.

Treat the AI agent as a commodity component and focus your value on the integration into the client's specific workflows, systems, and review processes.

IF your agency runs MCP servers for two or more clients and needs upstream credentials held centrally with per-client, per-tool allow/ask/block policies, THEN start on the Free tier (USD 0/mo, 25 source-built services, 50,000 tool calls a month) and move to Team at $25/mo per developer once you need the shared credential vault, roles, and 100,000 pooled tool calls per developer. IF client volume stays under roughly 50,000 calls a month and one developer owns delivery, the Free tier covers the work and a paid plan is premature. IF projected usage is unpredictable or clients resist per-call billing, DEFER, because Rayrun charges USD 0.2 per 1,000 calls and margin depends on forecasting client consumption.

Stand up a client's first MCP server behind a Rayrun endpoint so their AI tools reach upstream services through one URL while credentials stay in Rayrun's vault. The sprint ends with per-tool access rules, activity logging, and a handoff the client's team can operate.
