MCP Clients

Dense-Mem exposes MCP Streamable HTTP at:

http://127.0.0.1:8080/mcp

Use the hosted demo URL instead when testing the demo:

https://demo-dense-mem.markhuang.ai/mcp

Authentication

Every MCP request uses a Dense-Mem API key:

Authorization: Bearer dm_...

For local setup, create a key with:

bash

docker compose exec server /app/provision-team --name "primary-memory"
export DENSE_MEM_API_KEY="dm_..."

Claude Code

bash

claude mcp add --transport http dense-mem http://127.0.0.1:8080/mcp \
  --header "Authorization: Bearer $DENSE_MEM_API_KEY"

For the hosted demo:

bash

claude mcp add --transport http dense-mem-demo \
  https://demo-dense-mem.markhuang.ai/mcp \
  --header "Authorization: Bearer $DENSE_MEM_API_KEY"

Codex

Add this to ~/.codex/config.toml:

toml

[mcp_servers.dense_mem]
url = "http://127.0.0.1:8080/mcp"
bearer_token_env_var = "DENSE_MEM_API_KEY"
tool_timeout_sec = 60
enabled = true

For the hosted demo:

toml

[mcp_servers.dense_mem_demo]
url = "https://demo-dense-mem.markhuang.ai/mcp"
bearer_token_env_var = "DENSE_MEM_API_KEY"
tool_timeout_sec = 60
enabled = true

Check The Tool List

bash

curl -s "http://127.0.0.1:8080/mcp" \
  -H "Authorization: Bearer $DENSE_MEM_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'

The response should include tools such as:

remember
recall_memory
trace_memory
assemble_context
reflect_memories
confirm_memory

Read-only keys will not see write-scoped tools such as remember or confirm_memory.

Check Bundled Prompts

Dense-Mem also exposes MCP prompts for reusable LLM workflows:

bash

curl -s "http://127.0.0.1:8080/mcp" \
  -H "Authorization: Bearer $DENSE_MEM_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"prompts/list","params":{}}'

The response should include export_memory_as_agent_skill, a prompt that helps an LLM recall Dense-Mem context for a topic and draft a shareable Agent Skill SKILL.md file.

What To Ask

Use normal language:

Remember that I prefer concise explanations with concrete examples.

Then ask:

What do you remember about my explanation preferences?

The assistant should call Dense-Mem to save and recall memory. If it does not, check the client MCP configuration, the API key, and the server logs.
