GLM Subagent MCP

Describes the environment variables required to run the server.

Name	Required	Description	Default
`GLM_CAP`	No	Output-token cap. Off by default = generous (up to 131072 per call). Set on to enforce GLM_MAX_TOKENS. Default: off	off
`GLM_API_KEY`	Yes	Your Z.ai API key with GLM Coding Plan access. Required.
`GLM_BASE_URL`	No	Anthropic-compatible endpoint. Default: https://api.z.ai/api/anthropic	https://api.z.ai/api/anthropic
`GLM_COST_BIAS`	No	How hard to favor GLM (it's ~10x cheaper). Higher = more GLM; 0 = decide on capability only. Default: 1.5	1.5
`GLM_MAX_TOKENS`	No	The hard per-call limit applied only when GLM_CAP=on. Default: 32768	32768
`GLM_PEAK_MODEL`	No	Model used during China peak. Default: glm-5.2	glm-5.2
`GLM_PEAK_END_CN`	No	Peak window end (China hour, UTC+8). Default: 18	18
`GLM_OFFPEAK_MODEL`	No	Model used off-peak. Default: glm-5.2	glm-5.2
`GLM_PEAK_START_CN`	No	Peak window start (China hour, UTC+8). Default: 14	14
`GLM_MAX_CONCURRENT`	No	GLM caps in-flight requests; keep at 1. Default: 1	1
`GLM_AGENT_MAX_ITERS`	No	Max tool-loop turns for glm_agent. Default: 30	30
`GLM_MAX_TOKENS_CEILING`	No	The generous default used when the cap is off. Default: 131072	131072

Functions exposed to the LLM to take actions

Name	Description
glm_delegateA	Text-in/text-out subtask on GLM (~10x cheaper than Opus); returns text only. GLM has no file/tool access -- put everything in task+context. For file edits use glm_agent instead. Not for sensitive, long-debugging, large-refactor, or parallel work.
glm_agentA	Run GLM as a real coding agent with its OWN file tools (read/write/edit/list/bash); it works your repo end-to-end on GLM tokens (~10x cheaper than Opus). Prefer this over doing repo work yourself. Pass task + absolute workdir. Returns a concise summary+stats (use dry_run to preview a diff first). Not for sensitive, huge-context, or heavy dependent-tool-loop work.
glm_recommendA	Free local advisory (no GLM call): given a task profile, returns GLM-vs-Opus, model, confidence, and reasons. Call when unsure which engine to use.
glm_statusA	Free local status: peak window, active model, GLM usage ledger (proof of GLM tokens spent), and config health. No GLM call.
