Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.

This server publishes no instructions, or was last inspected before Glama recorded them.

Features and capabilities supported by this server

Protocol revision2025-11-25

Functions exposed to the LLM to take actions

Name	Description
deepseek_chatA	Chat with DeepSeek V4 models. deepseek-v4-flash (fast, economical) and deepseek-v4-pro (most capable), both 1M context with optional chain-of-thought thinking mode. deepseek-chat and deepseek-reasoner are accepted as backward-compatible aliases (resolve to v4-flash). Features: multi-turn sessions (session_id), function calling (tools parameter), thinking mode, JSON output mode, multimodal input (when enabled), automatic cost tracking, and model fallback with circuit breaker resilience.
deepseek_fimA	Fill-in-the-Middle (FIM) completion with DeepSeek V4. Provide a prompt (prefix) and an optional suffix; the model completes the text in between. Ideal for code completion and content infilling. Runs in non-thinking mode on the Beta endpoint; output is capped at 4K tokens. Aliases deepseek-chat and deepseek-reasoner resolve to deepseek-v4-flash (FIM has no thinking mode). Includes automatic cost tracking and model fallback with circuit breaker resilience.
deepseek_sessionsA	Manage multi-turn conversation sessions. List active sessions, delete a specific session, or clear all sessions. Sessions store conversation history for use with the session_id parameter in deepseek_chat.
