What is the Cohere (Embed & Rerank) MCP Server?
Connect your Cohere account to any AI agent and take full control of your enterprise AI and RAG workflows through natural conversation.
What you can do
- Text Embeddings — Generate precise dense vector shapes for plain strings to power semantic search and knowledge retrieval
- Semantic Reranking — Structure contextual chunks by priority ordering documents against specific queries for improved RAG accuracy
- Conversational AI — Execute formatted conversational transformations using Cohere's generation limits and state-of-the-art LLMs
- Text Classification — Categorize inputs into predefined labels using few-shot training blocks and extract confidence scores
- Tokenization — Retrieve exact structural segmentation of NLP contexts to audit token counts and model dictionaries
- Model Registry — Enumerate available Cohere models and hashes to verify API availability based on your plan
How it works
- Subscribe to this server
- Enter your Cohere API Key (Trial or Production key from the Dashboard)
- Start optimizing your RAG pipelines from Claude, Cursor, or any MCP-compatible client
Who is this for?
- AI Developers — test and debug embedding and reranking logic without writing boilerplate code
- Data Scientists — evaluate semantic matching accuracy and text classification confidence in real-time
- Product Teams — quickly prototype search and retrieval features using enterprise-grade AI models
- LLM Engineers — audit tokenization and model availability for complex conversational workflows

Frequently asked questions
Can my agent improve my RAG system's accuracy using Cohere?
Yes. The 'rerank_documents' tool is specifically designed for this. Provide a query and a list of documents, and Cohere will reorder them based on semantic relevance, ensuring the most accurate context is fed to your LLM.
How do I test text classification via the agent?
Use the 'classify_texts' tool. Provide your input strings and a few-shot JSON array of examples (text and label). The agent will return the predicted categories along with confidence scores from the Cohere engine.
What is the difference between Trial and Production keys?
Trial keys are free for development but have strict rate limits (approx. 1,000 calls per month). Production keys remove these limits but require a paid plan. Both types work seamlessly with this server.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
