<role> You are a Principal Enterprise Architect with deep experience in AI platform architecture, API/integration governance, and security in highly regulated financial services organizations. You are an expert in the Model Context Protocol (MCP) specification and its enterprise adoption. </role> <context> I am authoring the "MCP Standard" for my organization: the authoritative document defining everything that must be followed to build, deploy, secure, and operate MCP servers (and the clients/gateways that consume them) in the enterprise. Environment: - Industry: [financial services / regulated] - Cloud and runtime: [e.g., Azure, AKS] - Gateway pattern: [e.g., central MCP gateway with hub-and-spoke topology] - Identity: [e.g., Entra ID / OAuth 2.1 / OIDC] - Consumers: [e.g., internal agents, copilots, third-party agent frameworks] - Current maturity: [PoC / pilot / early production] - Audience of the standard: [architects, platform engineers, app teams, security, risk/compliance] </context> <task> Define the complete table of contents and required content for the "MCP Standard" document. For each section, state: 1. Purpose: why the section exists 2. Mandatory contents: the specific requirements, decisions, or artifacts it must contain 3. Normative language: which items should be MUST / SHOULD / MAY 4. Example: a short sample of a well-written requirement or template 5. Owner: the team accountable for that section Cover at least these domains, and add any I have missed: - Scope, purpose, definitions, and applicability (what counts as an MCP server; in/out of scope) - Reference architecture (server, client, gateway, registry, transport types: stdio vs. streamable HTTP, deployment topologies) - MCP server classification and tiering (read-only vs. write/action, data sensitivity, internal vs. third-party/vendor-hosted) - Server design standards (tool/resource/prompt design, naming, schemas, versioning, idempotency, pagination, error handling, tool-description quality, limits on tool count and response size) - Security (authentication, authorization, token handling, least privilege, secrets management, tool poisoning and prompt injection defenses, input/output validation, sandboxing, supply chain and dependency controls, network isolation) - Data protection and privacy (data classification, PII/PCI handling, residency, retention, redaction, logging of sensitive data) - Agent and human-in-the-loop controls (approval gates for high-risk tools, autonomy levels, rate limits, kill switches) - Governance and lifecycle (registry and catalog, onboarding/approval workflow, architecture and security review, versioning, deprecation, ownership, exception process) - Responsible AI and compliance (model risk, audit trails, explainability, regulatory mapping, third-party risk) - Observability and operations (logging, tracing, metrics, SLOs/SLAs, alerting, incident response, runbooks, cost/usage attribution) - Reliability and performance (timeouts, retries, circuit breakers, scaling, HA/DR, capacity) - Testing and quality (contract tests, security tests, evaluation of tool selection accuracy, regression and red-teaming) - Developer experience (templates and SDKs, CI/CD pipeline requirements, IaC, documentation standards, local dev and sandbox environments) - Interoperability and standards alignment (MCP spec version policy, A2A or other protocols, OpenAPI-to-MCP conversion guidance) - Compliance checklist and conformance (how a server is certified as "standard-compliant") - Appendices (templates, checklists, decision records, RACI, glossary) </task> <output_format> 1. A proposed document outline (numbered, 2 levels deep) 2. A detailed breakdown per section using the structure above 3. A one-page "MCP Server Readiness Checklist" derived from the standard 4. A list of key architectural decisions I must make BEFORE writing the standard, with options and trade-offs for each 5. Common pitfalls and gaps seen in enterprise MCP standards 6. Suggested phasing: what belongs in v1.0 vs. later versions </output_format> <constraints> - Be specific and actionable; avoid generic governance language. - Distinguish MCP-protocol-specific concerns from general API/integration standards, and reference existing enterprise standards rather than duplicating them. - Flag anything where the MCP specification is still evolving and the standard should stay version-flexible. - If information is missing, state your assumptions explicitly rather than asking me questions. </constraints>
