Agent Building

UiPath AgentHub MCP server registration + tool authoring via `uip agenthub mcp` (six server types: uipath / coded / command / remote / platform / swagger) and `uip agenthub mcp-tools` (three tool kinds: is-activity / resource / raw on `uipath`-type servers). For Integration Service activity authoring→load `references/is-activity-workflow.md`. For Python MCP servers / coded-agent integration→uipath-agents. For raw IS CLI→uipath-platform.

UiPath AgentHub MCP Servers

Register AgentHub MCP servers via uip agenthub mcp. Author tools on uipath-type servers via uip agenthub mcp-tools.

mcp here means an AgentHub MCP-server resource, not the MCP wire protocol. Slugs like inbox-mcp / team-helper name AgentHub server registrations, not local repos. uipath-mcp-python (@uipath/mcp) is a separate server-implementation SDK — different task, see uipath-agents.

When to Use This Skill

Create / update / delete / refresh / list / get an AgentHub MCP server (any of: uipath, coded, command, remote, swagger, platform).
Author / list / get / enable / disable / delete tools on a uipath-type server (is-activity, resource, raw).
For is-activity tools (Integration Service connector activities), load references/is-activity-workflow.md end-to-end before authoring. It owns the Pre-flight, cascade, designTimeLookups, ActivityMetadata schema, and connector-specific troubleshooting.
Skip: Python MCP server implementation (FastMCP / @uipath/mcp) → uipath-agents. Raw IS CLI outside MCP tooling → uipath-platform.

Trust the CLI

The CLI is the source of truth for shapes and flags. Use it instead of guessing:

uip agenthub mcp create <type> --print-schema --output json — payload shape for any server type.
uip agenthub mcp template <type> --output json — ready-to-edit --file skeleton.
uip agenthub mcp-tools template <kind> --output json — tool payload skeleton (is-activity / resource / raw).
uip agenthub mcp-tools candidates --category <kind> --output json — discover bindable targets. <kind> ∈ automation | agent | agentic-process | api-workflow | is-activity.
--output-filter <JMESPath> on every command — extract specific fields without walking JSON by hand (e.g. --output-filter "Data.items[].slug" --output plain).
--dry-run on every mutating call — resolve and inspect the body before POST. Note: --dry-run skips some server-side validation, so a clean dry-run is not a guaranteed real POST.

Critical Rules

These are the things the CLI does not advertise in --help.

Slug regex. Backend enforces ^[a-z0-9-]+$, length 3-50. Lowercase, digits, hyphens — no underscores, dots, or uppercase. CLI validates client-side before POST.
Folder context is required on every AgentHub call. Pass --folder-path <name> OR --folder-key <guid>, never both. Exception: mcp list --all-folders spans every folder you can see (mutually exclusive with the folder flags; folders without AgentHub permission are skipped with a Warning line) — use it to locate a server when its folder is unknown, then pass that folder explicitly on every follow-up call (mcp-tools verbs have no --all-folders). --folder-path resolves via Orchestrator SDK. Personal workspace folders (<user>@<tenant>'s workspace) do NOT resolve by name — use --folder-key <guid>. Common names (Shared) can be ambiguous across nested folders; the CLI returns the candidate list with GUIDs — pick one and re-run with --folder-key. Discover GUIDs via uip or folders list --output json. refresh-tools always requires --folder-key specifically (endpoint is /mcp/{folderKey}/{slug}/refresh-tools).
Verify after every mutation. After create / update / delete / refresh-tools, re-list (mcp list, mcp-tools list --mcp <slug>) or mcp get <slug> and confirm the expected state.
refresh-tools behavior depends on server type.
- coded / command — async, returns HTTP 202 + runtime id. Surface the runtime id; never claim refreshed before a follow-up mcp-tools list --mcp <slug> confirms.
- remote / platform / swagger — sync, returns 200 after a synchronous fetch+upsert.
- uipath / selfhosted — rejected locally; tools are manually authored via mcp-tools create-*. CLI emits a NextCommand hint to author instead.
mcp delete looks up by slug, not GUID. Passing a GUID returns 404.
For any is-activity tool, read references/is-activity-workflow.md end-to-end before any CLI call. It owns the cascade-asking gate, the action-triggered platform-IS reads, the ActivityMetadata schema, and the inputSchema / designTimeLookups rules. IS metadata authored from memory passes --dry-run but fails at runtime — do not skip the reference. Reason: IsActivityNotAvailable from ANY is-activity verb → STOP immediately: no further is-activity calls (no create attempt "to confirm" — the error covers every verb), no --force without explicit user approval; the gate follows the payload — an IS-activity payload (type: 1 + processType: Api) via create-raw / create-resource / update --file/--body is gated identically; offer resource / raw instead (genuinely different kinds, not the same payload re-verbed — reference §Availability).

Server Types

uip agenthub mcp create takes six type subcommands. All share --name <display>, --slug <kebab>, --description, --version, --file/--body/--print-schema, --dry-run, --folder-path/--folder-key, --tenant, --login-validity. The differentiating flag picks the integration shape:

Type	Differentiating flag	When to use	Tool surface
`uipath`	(none)	AgentHub-hosted server you'll fill with `mcp-tools create-*`.	Authored via `uip agenthub mcp-tools create-*`. `refresh-tools` rejected.
`coded`	`--process-key <key>` (+ `--folder-key` for the process)	Wrap an existing coded-agent process (published to Orchestrator) as an MCP server.	Discovered via `refresh-tools` (async 202).
`command`	`--command <cmd>` + `--arg <arg>` (repeatable) + `--env <k=v>` (repeatable)	Spawn a local subprocess as an MCP server.	Discovered via `refresh-tools` (async 202).
`remote`	`--uri <url>` + `--header <k=v>` (repeatable) + `--use-relay`	Point at an existing HTTP MCP server. Bearer/header values can be Orchestrator asset references; `AssetReferenceSubstitutor` resolves them at runtime via the caller's token + folder context. Do NOT invent a credential-store syntax.	Discovered via `refresh-tools` (sync 200).
`platform`	`--service <name>` (lowercase service id, e.g. `orchestrator` — the CLI `--help` example's capitalized `Orchestrator` is rejected with HTTP 400) + `--tool <name>` (repeatable; selects exposed platform tools)	Bind to a first-party UiPath service.	Discovered via `refresh-tools` (sync 200).
`swagger`	`--spec-url <url>` (+ `--use-relay`)	Register an OpenAPI/Swagger spec as MCP tools. Same asset substitution as `remote`.	Discovered from the spec via `refresh-tools` (sync 200).

Headers/auth on remote and swagger are payload fields, not scalar flags. Read the shape from --print-schema (or template <type>), submit via --file <payload.json> or --body '<json>'.

mcp update <slug> dispatches by existing server type — flag shape mirrors create <type>. Verify with mcp get <slug> --output json.

mcp template <type> also accepts process-assistant and selfhosted — these have templates but NO create subcommand (backend enum only; skip).

Tool Kinds (`uipath`-type servers only)

uip agenthub mcp-tools create-{is-activity | resource | raw}. Shared flags: --mcp <slug> (parent server), --name, --description, --target-identifier <guid> / --target-name <name> (resolve target via RCS — only for non-activity categories), --folder-key <guid> / --folder-path <name> (MCP server folder context), --target-folder-key <guid> / --target-folder-path <name> (any kind — the target's folder — IS connection / Orchestrator resource / raw payload target — when it differs from the server's; resolves to the tool's targetFolderKey; never both; omit to default to the candidate's folder (--target-name) or the server folder; the explicit flag wins, including over a --file/--body payload field), --category, --input-schema, --output-schema, --metadata, --continue-on-error (default) / --fail-fast, --file/--body, --dry-run. Differ in metadata shape, discovery path, and validation strictness.

Kind	Discovery	Validation	When to use
`is-activity`	`mcp-tools candidates --category is-activity` + `is resources describe`	Connector schema	Wrap an Integration Service connector activity as an MCP tool. Load references/is-activity-workflow.md end-to-end — extra Critical Rules, Pre-flight, `ActivityMetadata` schema, and IS-specific troubleshooting apply. Rolling out: unavailable environments fail with `Reason: IsActivityNotAvailable` — follow the reference's §Availability (stop; offer `resource` / `raw`).
`resource`	`mcp-tools candidates --category <kind>` (kind ∈ `automation` / `agent` / `agentic-process` / `api-workflow`)	Resource schema	Bind an Orchestrator resource. Pass `--target-identifier <resource-id>`. Read metadata shape from `mcp-tools template resource --output json`. `candidates` is tenant-wide — each item carries its `folder {key, name}`; present the folder alongside the name when the user picks. `--target-name` lookup searches the server folder by default; resource in a different folder → pass `--target-folder-path` / `--target-folder-key` (scopes the lookup AND sets the tool's `targetFolderKey`); with `--target-identifier`, pass the same flags when the resource's folder differs from the server's.
`raw`	None	None	Free-form JSON tool — caller owns correctness end-to-end. No discovery, no schema validation, no reference-value labeling. Read the skeleton from `mcp-tools template raw --output json`.

Stringify --metadata / --input-schema / --output-schema as scalars (not --file). Build each JSON in a file and pass it as --metadata "$(jq -c . metadata.json)" (likewise input/output schema) — do not assemble multi-KB JSON inline in the command. Pass --output-schema "{}" when the underlying target has no response fields — empty string is rejected with Unexpected end of JSON input.

Other mcp-tools verbs (list --mcp <slug>, get, enable, disable, delete, update) are self-documenting via --help. Use them for the Critical Rule 3 verify step. update also accepts --target-folder-key / --target-folder-path: retargeting via --target-identifier defaults the tool's targetFolderKey to the server folder — pass the explicit flag when the new target lives elsewhere (wins over the default and over a --file/--body payload field).

Troubleshooting (generic)

HTTP 400 with no detail — re-run with --dry-run to inspect the resolved body. CLI surfaces ASP.NET ProblemDetails as an Errors field listing per-field validation failures.
InvalidFolderKey: "--folder-key requires a GUID; use --folder-path for folder names" — switch to --folder-path <name>.
No folder named '<personal workspace>' was found. Did you mean: Shared? — personal workspaces are unresolvable by name; pass --folder-key <guid> (Critical Rule 2).
ConflictingInput: "Pass either --folder-path or --folder-key, not both." — drop one.
Slug rejected with validation error — backend enforces ^[a-z0-9-]+$, length 3-50 (Critical Rule 1).
mcp delete <guid> returns 404 — mcp delete looks up by slug, not GUID (Critical Rule 5).
refresh-tools returns 202 with a runtime id — coded / command refreshes are async (Critical Rule 4). Surface the runtime id; verify via follow-up mcp-tools list --mcp <slug>.

Tool-kind-specific troubleshooting lives with the workflow that owns it — IS-activity troubleshooting is in references/is-activity-workflow.md.
