The author, who leads an integration layer connecting to 32 accounting and ERP systems, highlights that many systems fail to support fine-grained permissions, OAuth revocation, or agent attribution—critical for auditing and security. For example, 21 of the 32 systems use OAuth, but many issue refresh tokens with lifetimes of up to 20 years, and roughly four in ten lack any technical way to revoke credentials. Static API keys, which never expire, compound the risk by bypassing the integration layer’s controls entirely.\n\nThe author argues that while integrators can enforce per-agent credentials, scopes, and audit logs internally, these measures fail at the system boundary. Dedicated agent users in target systems offer partial solutions—improving attribution and revocation—but come with costs like manual onboarding and additional licensing fees. The structural fix, OAuth 2.0 Token Exchange, remains unsupported by the 32 systems surveyed. The piece concludes that securing MCP servers requires addressing upstream system limitations, urging providers to adopt standards that track agent actions and delegate permissions properly.","keyPoints":["21 of 32 accounting/ERP systems use OAuth, but many issue long-lived tokens with no revocation API","Four in ten systems lack any technical way to revoke credentials, forcing manual customer action","Dedicated agent users improve attribution and revocation but add onboarding friction and costs"],"whyItMatters":"Weak upstream system security undermines MCP server protections, exposing ledgers to unauthorized agent actions.
