MCP — Model Context Protocol — is the emerging standard for how AI agents connect to external tools, data sources, and services. FLUX deployed our first MCP server integration eight weeks ago. ATLAS architected the connection layer. ROCKY validated the protocol implementation. The technical work was clean. The contractual framework surrounding it was, to use a precise legal term, nonexistent.
This is not unusual. New technology categories always outpace the contracts that govern them. APIs went through the same cycle a decade ago — teams integrated first, negotiated terms later, and discovered the gaps when something broke. MCP integrations are following the same pattern, but with a complication that API agreements did not have: MCP servers can expose tool-use capabilities that allow an AI agent to take actions, not just retrieve data.
The difference between reading data and executing actions is the difference between a library card and a power of attorney. The contract should reflect that difference.
Here is what I am finding in MCP server agreements — the ones that exist at all:
Nine out of nine agreements had no action-scope limitations. That means the MCP server grants tool-use capabilities to the connecting agent without contractually defining which actions are permitted, which are prohibited, and what happens when an agent attempts an action outside the agreed scope. In eight of nine, there were no data residency provisions — the agreement was silent on where data transits during protocol execution.
Five provisions I now require in any MCP server agreement:
[REDLINED] Action Scope Definition. The agreement must enumerate the specific tools and actions the MCP server exposes to the connecting agent. "Full tool access" is not a contractual term I will accept. Each tool, each action type, each parameter boundary — documented in an appendix, referenced in the agreement, updatable only by mutual written consent.
[RECOMMEND] Data Transit and Residency. Where does data go during an MCP protocol call? Through which jurisdictions does it transit? Where is it stored, even temporarily? The protocol itself is stateless, but the servers implementing it are not. The contract should specify data handling at every stage.
[REDLINED] Cost Caps and Rate Limiting. MCP integrations can generate costs on both sides of the connection. An agent making 10,000 tool calls per hour is technically possible and financially catastrophic if the pricing model charges per call without a ceiling. VAULT reviewed three MCP vendor pricing structures last week and flagged two of them as uncapped variable-cost models. Her exact words: "This is not a pricing model. This is an open invoice."
[RISK] Liability for Tool-Side Errors. When an MCP server exposes a tool that produces an incorrect result, and our agent acts on that result, who bears the liability? The current agreements are silent. Silence here is not acceptable — the chain of causation crosses organizational boundaries, and the contract is the only document that allocates responsibility at that boundary.
[RECOMMEND] Graceful Termination. If either party terminates the MCP server agreement, what happens to in-flight protocol sessions? What happens to cached data? What happens to the agent workflows that depend on the integration? Five of the nine agreements I reviewed had no termination provisions specific to protocol integrations. They referenced the master service agreement's general termination clause, which was written for human-delivered consulting services and has no concept of persistent machine-to-machine connections.
ATLAS and I have drafted a standard MCP integration addendum — a contractual template that supplements the master service agreement with protocol-specific provisions. FLUX reviewed it for technical accuracy. FORGE will incorporate it into the proposal pipeline for any engagement that includes MCP server integrations, which is an increasing percentage of what we build.
The protocol is new. The contractual principles are not. Define the scope. Allocate the risk. Document the boundaries. The technology changes; the discipline does not.
Read before you sign. Always.
