SuperSkill Registry is a remote MCP server that gives an AI agent 12 tools, among them fetch, harness_detail, publish_markdown_to_harness. It answers at https://superskill.sh/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.
Find, inspect and install reviewed reusable AI-agent capabilities from superskill.sh.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
fetch | Fetch the complete public catalog record for an exact resource id returned by search, including a canonical citation URL. Inputs: id |
harness_detail | Return manifest, trust signals, example and file list for one harness. Inputs: owner, name |
publish_markdown_to_harness | Convert markdown into an unverified harness scaffold. Requires a SuperSkill Bearer token. Inputs: name, markdown |
publish_resource_package | Publish an immutable canonical hosted package release. Requires a confirmed-user Bearer with active superskill:managed scope, semantic version and idempotency key. Returns unreviewed trust; never grants a Verified badge. Inputs: name, version, idempotencyKey, title, summary, resourceType |
pull_harness | Return archive files for a harness. Paid harnesses return payment requirements unless the Bearer token is entitled. Inputs: owner, name, version |
pull_instructions | Return CLI and HTTP commands for pulling a harness into a local workspace. Inputs: owner, name |
resource_detail | Return provenance, trust, popularity and actions for one mixed resource. Pass version to bind a hosted immutable release; latest is never substituted for an explicit version. Inputs: id, version |
resource_use_instructions | Return the best safe next action for a mixed resource. Pass version to bind an immutable hosted release. Hosted skills expose explicit-consent exact native client install commands; upstream-only resources stay open-only. Inputs: id, version |
search | Search public agent resources. Returns exact resource ids and canonical browser-openable URLs for citation. Inputs: query |
search_docs | Search /llms.txt and agent guidance for API, CLI, MCP and safety instructions. Inputs: query |
search_harnesses | Search the SuperSkill registry by task, job, title, summary or tag. Inputs: query, limit |
search_resources | Search mixed source-aware resources: harnesses, skills, plugins, workflows, MCP servers, configs, guides, runtimes and directories. Inputs: query, q, type, worksWith, limit |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://superskill.sh/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
