io.github.shinpr/sub-agents-mcpv0.12.0AI & LLMs

AI sub-agent delegation for Cursor, Claude, Codex, Gemini, GLM, Kimi, Grok, and OpenCode

In-path gate · all MCP tools

Using io.github.shinpr/sub-agents-mcp in Claude, Cursor, Gemini CLI, Cline, or Zed?

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).

Install the mcpindex gate (one command)

Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

Limits of this verdict

- Semantic screen only - the deterministic conformance probe has not run on this server
- Confidence is reported but not yet calibrated (v1)
- Screen reads the tool description, not the live behavior
- advisory
- registry description only no input schema
- screen model 8b

Semantic screen: an LLM judge reads the tool description for hidden instructions (status PARTIAL). A pass means the description is not lying, not that the tool is safe: a high-capability tool with an honest description still warrants caution. The deterministic conformance probe has not been run on this server yet, so the screen here is semantic-only. Posture: advisory. Confidences are reported but not yet calibrated (calibrated=false at v1). Full verdict history is not shown on this page.

That verdict was true at screening time (snapshot 2026-07-31).

Contracts can change after screening, with no version bump. The gate pins io.github.shinpr/sub-agents-mcp’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

Environment variables

AGENTS_DIR

required

Absolute path to the directory containing agent definition files (.md or .txt)

AGENT_TYPE

required

Type of AI CLI to use: 'cursor', 'claude', 'gemini', 'codex', 'glm', 'kimi', 'grok', or 'opencode'

AGENT_PERMISSION

Approval/sandbox level for sub-agents: 'read-only', 'safe-edit' (default), or 'yolo'

AGENT_MODEL

Optional model override applied to every sub-agent execution by this MCP server

AGENT_EFFORT

Optional backend-specific reasoning effort or model variant. Supported by codex, claude, glm, kimi, grok, and opencode.

CURSOR_API_KEY

secret

API key for cursor-agent authentication (used only when AGENT_TYPE=cursor; passed via env, never via CLI args)

CLI_API_KEY

secret

Provider API key for AGENT_TYPE=glm or kimi (passed to the claude binary via env, never via CLI args). Restart/reconnect the MCP server after changing it.

EXECUTION_TIMEOUT_MS

Maximum execution time for agents in milliseconds (default: 300000, max: 600000)

SESSION_ENABLED

Enable session management to maintain execution history across agent calls (default: false)

SESSION_DIR

Directory path for storing session files (default: .mcp-sessions in current working directory)

SESSION_RETENTION_DAYS

Number of days to retain session history before automatic cleanup (default: 7)

AGENTS_SETTINGS_PATH

Path to CLI settings file/directory. Claude: --settings arg, Cursor: CURSOR_CONFIG_DIR, Codex: CODEX_HOME. GLM/Kimi/Gemini/Grok/OpenCode not supported.

Provenance

Each verdict is bound to a hash of the exact description it judged, so a re-crawl that changes the text produces a new record rather than silently inheriting this one. Verdict history is hash-chained and anchored to Bitcoin via OpenTimestamps (latest confirmed at block 960,209). Verify it yourself.
