mcp-dynamic-orchestratorDynamic MCP server discovery and code-mode execution via central registry.
MCP Dynamic Orchestrator is an agent skill from secondsky/claude-skills. Dynamic MCP server discovery and code-mode execution via central registry. Use for multiple MCP integrations, tool discovery, progressive disclosure, or encountering MCP context bloat, changing server sets, large tool sets.
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including scripts and reference files (for example `references/mcp-protocol.md`, `references/registry-schema.md` and `references/security-model.md`).
It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol, Cloudflare and TypeScript. The repository describes itself as: Production-ready skills for Claude Code CLI - Cloudflare, React, Tailwind v4, and AI integrations. The licence is MIT.
3 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 8837836. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
list_mcp_capabilitiesdescribe_mcpexecute_mcp_codeFrom allowed-tools in the SKILL.md frontmatter.
Ships 3 files in scripts/ (TypeScript), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
docs.mcp.cloudflare.comFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
MCP Dynamic Orchestrator loads about 1.5k tokens when it runs, and up to ~21k if it reads all its reference files. Until then it costs about 62 tokens; SKILL.md has 532 words of instructions outside code blocks.
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.
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); the scripts in this folder are not scanned.

.claude/skills/mcp-dynamic-orchestrator/SKILL.md (or your agent's skills folder). This skill also uses 7 other files; get the full folder from GitHub.Use this skill to:
mcp-clients/* modules.If no MCP servers are configured, list_mcp_capabilities will respond with an empty list
and a message pointing to skills/mcp-dynamic-orchestrator/mcp.registry.json so the user
can add MCP entries.
This skill reads from mcp.registry.json, so adding an MCP entry there (for example the
Cloudflare MCP) automatically makes it discoverable without changing tool wiring.
The Cloudflare MCP server can be configured in mcp.registry.json like this:
{
"id": "cloudflare",
"title": "Cloudflare platform MCP",
"summary": "Interact with Cloudflare's MCP endpoint for documentation, examples, and platform operations exposed via the official Cloudflare MCP server.",
"mcp": {
"transport": "stdio",
"command": "npx",
"args": [
"mcp-remote",
"https://docs.mcp.cloudflare.com/sse"
]
},
"domains": ["cloudflare", "workers", "kv", "r2", "queues", "zero_trust", "networking", "security", "observability"],
"tags": ["cloudflare", "platform", "infra", "docs", "workers", "mcp"],
"examples": [
"Fetch Cloudflare Workers documentation for a specific API.",
"Search Cloudflare platform docs for queues or KV usage patterns.",
"Look up configuration guidance for Zero Trust or networking features."
],
"sensitivity": "low",
"visibility": "default",
"priority": 10,
"autoDiscoverTools": true
}With this entry present:
list_mcp_capabilities will return cloudflare when queries mention Cloudflare, Workers, KV, R2, Queues, etc.describe_mcp with id: "cloudflare" will surface concise tool summaries from the Cloudflare MCP server.execute_mcp_code lets the agent write TypeScript such as:import * as cloudflare from "mcp-clients/cloudflare";
async function main() {
const docs = await cloudflare.search_docs({ query: "Workers KV" });
console.log(docs.summary);
}The actual available functions under mcp-clients/cloudflare are generated dynamically
from the MCP tool definitions; the agent should always:
list_mcp_capabilities.describe_mcp to see available operations.execute_mcp_code.list_mcp_capabilities with a natural language query or filters to see which MCPs exist.cloudflare), call describe_mcp to understand its operations.mcp-clients/<id> and calls the exported functions.execute_mcp_code, optionally restricting allowedMcpIds for safety.execute_mcp_code.detail: "schema" in describe_mcp only when exact parameter shapes are required.⚠️ The current sandbox implementation is NOT secure for untrusted code.
⚠️ The
vm-based sandbox is NOT a security boundary. Node'svmmodule can be escaped (see Node docs). This setting reduces accidental damage only. For untrusted MCP entries, run them in a separate process/container with proper OS-level isolation.
vm.createContext() which is NOT a security boundaryMCP_ORCH_ENABLE_SANDBOX=1 environment variablereferences/security-model.md for complete security detailsWhen adding entries to mcp.registry.json, the orchestrator enforces:

Set MCP_ORCH_ALLOW_RAW_COMMANDS=1 to opt out (loud stderr warning; only for fully-trusted registries).PATH, NODE_OPTIONS, LD_PRELOAD, DYLD_INSERT_LIBRARIES, PYTHONPATH, etc. are stripped from mcp.env before spawn (stderr warning per dropped key)..ts format will failmcp-clients/* don't resolve; use $call() APIFor detailed troubleshooting, see references/troubleshooting.md.

Dynamic MCP server discovery and code-mode execution via central registry. MCP Dynamic Orchestrator is an agent skill from secondsky/claude-skills. Dynamic MCP server discovery and code-mode execution via central registry.
MCP Dynamic Orchestrator fits situations like: multiple MCP integrations; progressive disclosure; encountering MCP context bloat; changing server sets.
Run `npx skills add secondsky/claude-skills --skill mcp-dynamic-orchestrator -a claude-code`. Or copy the skill folder (plugins/mcp-dynamic-orchestrator/skills/mcp-dynamic-orchestrator in secondsky/claude-skills) into .claude/skills/mcp-dynamic-orchestrator in your project. Claude Code loads it when a task matches its description.
Run `npx skills add secondsky/claude-skills --skill mcp-dynamic-orchestrator -a codex`. Or copy the skill folder (plugins/mcp-dynamic-orchestrator/skills/mcp-dynamic-orchestrator in secondsky/claude-skills) into .agents/skills/mcp-dynamic-orchestrator in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add secondsky/claude-skills --skill mcp-dynamic-orchestrator -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/mcp-dynamic-orchestrator, .gemini/skills/mcp-dynamic-orchestrator, .github/skills/mcp-dynamic-orchestrator and .opencode/skills/mcp-dynamic-orchestrator in your project.
Going by SKILL.md and its folder, MCP Dynamic Orchestrator needs TypeScript for the scripts in its folder. Our summary lists: Node.js. Its frontmatter pre-approves these tools: list_mcp_capabilities, describe_mcp, execute_mcp_code.
SKILL.md names 1 domain. In commands or code: docs.mcp.cloudflare.com; the agent is likely to contact it when it follows the instructions. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
MCP Dynamic Orchestrator is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.5k tokens (SKILL.md is roughly 5.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 20k tokens, read only when the agent opens those files.
