A housing IT team shares case APIs across chatbots. Which MCP deployment fits?

Housing IT sharing case APIs across multiple chatbots should deploy an MCP server independently so case connectors, schemas, and credentials are maintained outside each chatbot binary. Independent deployment lets teams update the case integration once and attach many Claude surfaces without forking glue code or redeploying every bot for an API change. Bundling a dedicated case MCP server inside each isolated chatbot process for faster startup silos the case integration inside every bot, so case connectors are not maintained centrally outside the chatbots and any API or auth change must be repackaged and redeployed per process. Publishing case tools through a public MCP registry for partner team discovery exposes sensitive housing case APIs beyond the intended chatbot consumers, weakens access control, and widens the blast radius of a public leak. Exposing case APIs over local stdio transport from a shared workstation process ties the case integration to a single workstation rather than an independently deployable server, producing an unstable shared endpoint and inconsistent case semantics across resident-facing bots. Exam caveat: independence does not mean unauthenticated openness—the MCP host must enforce service identity, scopes, and housing data-minimization rules per consumer, with audit logs suitable for case-access reviews. Operational check: rotate a case API credential only on the MCP server and confirm all chatbots continue working after reload; verify no case secrets remain in chatbot repositories; onboard a new surface by configuration rather than new connector code; and confirm a revoked consumer identity can no longer call case tools.
