At a glance

Adds, removes or updates MCP servers in a holaOS workspace by editing workspace.yaml in the mcp_registry format, with rules for headers, local servers and tool allowlists.

Works in 6 steps: Edit workspace.yaml at the workspace… → Workspace-level MCP lives under… → Tool ids in… → …
Adding a remote HTTP MCP server to a holaOS workspace
SKILL.md covers Core Rules, Remote Server Shape, Local Server Shape and Workspace Tool Catalog Shape, plus 2 more sections
Reaches mcp.context7.com; needs CONTEXT7_API_KEY

What it does

The skill covers MCP access in a holaOS workspace. The agent edits workspace.yaml at the workspace root and puts workspace-level MCP under mcp_registry, rather than creating mcp.json, .cursor/mcp.json, claude_desktop_config.json or another generic config unless you ask for that format. It is guidance only, so the target workspace config is updated and no new files are written under the embedded-skills folder.

The rules cover tool ids in mcp_registry.allowlist.tool_ids, which must use strict server.tool syntax. Omitting the list or leaving it empty keeps every discovered tool from enabled servers, and mixed mode is allowed. Remote HTTP servers take header values that are either a literal secret or an environment-variable reference in the env: form, and a secret wrapped in that syntax is called out as invalid. Local stdio servers need a non-empty list of command tokens.

Workspace-local tools implemented in the repo go under mcp_registry.catalog, where the workspace server must stay local and each allowlisted workspace tool needs a matching catalog entry. For tools from a workspace app's app.runtime.yaml, the skill prefers the app-managed flow, where the runtime reconciles the registry entries. It ends by reopening workspace.yaml to confirm the final shape.

When your agent uses it

Adding a remote HTTP MCP server to a holaOS workspace
Restricting which tools of an MCP server the workspace may use
Registering a local stdio MCP server in workspace.yaml

Example prompts

“Add the Context7 MCP server to this workspace with its API key read from an environment variable.”
“Restrict the docs server to its read tools only in workspace.yaml.”
“Register a local stdio MCP server that runs from ./tools/mcp-notes.”

Requirements

A holaOS workspace with a workspace.yaml

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

Edit workspace.yaml at the workspace root. Do not create mcp.json, .cursor/mcp.json, claude_desktop_config.json, or another generic MCP…
Workspace-level MCP lives under mcp_registry.
Tool ids in mcp_registry.allowlist.tool_ids must use strict server.tool syntax.
Omitting mcp_registry.allowlist.tool_ids or setting it to [] means all discovered tools from enabled configured servers stay available for…
Mixed mode is valid: some servers can be constrained by explicit allowlisted tool ids while other enabled servers stay discover-all.
This embedded skill is guidance only. When the user asks to add MCP to a workspace, update the target workspace config instead of writing…

What it can do on your machine

Read from SKILL.md and the folder at commit 4684714. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are yaml).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- mcp.context7.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- CONTEXT7_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

holaOS MCP Configurator loads about 874 tokens when it runs. Until then it costs about 22 tokens; SKILL.md has 345 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~22
When it runs · the whole SKILL.md, loaded when a task matches: ~874

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 345 words (~874 tokens).
