Reusable agent definitions authored as AGENTS.md (YAML frontmatter + a Markdown body that becomes
the agent's operating guide). Mirrors the skill library, including its review hardening.
- AgentProfile entity (OrgBoard): org-scoped + versioned by (OrganizationId, ProfileKey, Version),
NULLS NOT DISTINCT unique index; Origin Builtin|Authored|Installed; ProfileVisibility +
ProfileStatus with the Public⟹Published invariant enforced in Apply()/SetVisibility(). AGENTS.md
parser (YamlDotNet). AgentProfileWriter is the single upsert path (insert-only mode for install).
- Free builtins: AgentProfileSeeder seeds Aria (PO), Quill (QA), Edison (backend) on startup via a
new IStartupSeeder + SeederRunner (runs after migrations). Idempotent, null-org, visible to all.
- Endpoints (/api/orgboard/agent-profiles): upload, list (resolvable-winner order), get versions,
publish/unpublish, fork, marketplace (per-(key,version) AlreadyInLibrary), install (insert-only →
clean 409, no clobber). ConfigureAgents to author/manage; ViewBoard to browse; audited.
- Persona: Agent gains Persona; ConfigureAgent stores it; AgentRunContext carries it; PromptAssembler
injects it as "# Operating guide" (data, not instructions) so an applied profile shapes the run.
- Client: Agent profiles page (library + marketplace tabs, upload editor, publish/unlist/fork/install),
routed + in the nav.
Verified: ArchitectureTests 8/8, IntegrationTests 55/55 (new AgentProfilesTests: builtins seeded,
upload + validation, publish, cross-org marketplace list→install→private copy, duplicate 409, per-
version flag, Member 403; persona renders as the operating guide), client build green.

Agents can now use Model Context Protocol servers. End to end:
- SharedKernel seam IMcpGateway (ListToolsAsync / CallToolAsync) + McpToolDescriptor / McpToolResult,
so the Assembler discovers and can invoke MCP tools without referencing Integrations' tables.
- Integrations: McpServerConfig (org-scoped, owner-only; auth headers AES-GCM encrypted, never
returned — only their names) + AddMcpServers migration. McpClient: a dependency-free Streamable-HTTP
JSON-RPC 2.0 client (initialize → notifications/initialized → tools/list / tools/call), carrying the
Mcp-Session-Id and parsing both application/json and text/event-stream replies. McpGateway resolves
an org's servers, decrypts headers server-side, and is best-effort: an unreachable server is logged
and skipped, never failing the run. CRUD + connectivity-test endpoints (create/test/delete owner-only
via ManageApiKeys; list via ConfigureAgents to bind).
- OrgBoard: Agent gains McpServerIds (uuid[]; migration backfills existing agents to empty) flowing
through ConfigureAgent + AgentRunContext.
- Assembler: AgentRunExecutor lists the agent's MCP tools (best-effort) and PromptAssembler renders a
"# Tools (MCP)" catalog — labelled as data, never instructions — and records it in the run trace.
- Client: SeatsPage gains an MCP servers card (add/test/delete, encrypted auth header) and a per-agent
MCP server multi-select; api client gains del().
Note: discovery + the governed call gateway are in place now; the autonomous model-driven tool-call
loop (model emits tool_calls → gated execution → feedback) needs a tool-calling model client and is
the next increment — the stub model can't drive it.
Verified: ArchitectureTests 8/8, IntegrationTests 53/53 (McpClientTests: JSON-RPC handshake/session,
json + SSE; McpServerRegistryTests: owner-only, encrypted-header-never-returned, graceful test,
Member 403; PromptAssemblerMcpTests: catalog + trace, omitted when empty), client build green.
