qmcp-qdrant 0.1.4

Qdrant MCP Server for OpenCode - semantic search for code and documentation

qmcp - QDrant MCP Server for OpenCode

Semantic search server for code and documentation using Qdrant vector database.

Features

• Semantic Search: Find code and documentation using natural language queries
• Multi-language Support: Python, Go, JavaScript, TypeScript, Java, C#, Markdown
• Live Updates: File watcher for automatic reindexing
• Incremental Indexing: Only index changed files
• Cleanup: Remove stale vectors for deleted/changed files
• Diagnostics: Introspection tools to understand what's indexed
• OpenCode Skill: Natural language interface for Qdrant management

Installation

Via PyPI (Recommended)

pip install qmcp-qdrant

Via uv

uv tool install qmcp-qdrant

From Source

git clone https://github.com/BigKAA/qmcp.git
cd qmcp
make install

Quick Start

1. Ensure Qdrant is running

# Use existing Qdrant instance
export QDRANT_URL=http://localhost:6333

For Kubernetes deployment, see Qdrant on Kubernetes.

2. Add MCP Server to OpenCode

opencode mcp add qmcp-qdrant -- qmcp-qdrant

With custom Qdrant URL:

QDRANT_URL=http://192.168.218.190:6333 opencode mcp add qmcp-qdrant -- qmcp-qdrant

3. That's It!

OpenCode will automatically discover and use the semantic search tools.

MCP Tools

Search & Indexing

Tool	Description
qdrant_search	Semantic search in code/docs
qdrant_index_directory	Index a directory
qdrant_reindex	Reindex (full or incremental)

Collection Management

Tool	Description
qdrant_list_collections	List all collections
qdrant_get_collection_info	Get collection info
qdrant_delete_collection	Delete collection

Diagnostics & Introspection (NEW)

Tool	Description
qdrant_diagnose_collection	Full collection diagnostics - vectors, files, types, issues
qdrant_list_indexed_files	Paginated list of indexed files with metadata
qdrant_diff_collection	Compare Qdrant state with filesystem (orphans, missing, modified)

Maintenance

Tool	Description
qdrant_cleanup	Clean stale vectors (dry-run supported)
qdrant_watch_start	Start file watcher
qdrant_watch_stop	Stop file watcher
qdrant_get_status	Server status

Diagnostic Tools Usage Examples

# Diagnose a collection - see what's indexed, file types, issues
qdrant_diagnose_collection(collection="myproject")

# List indexed files with pagination
qdrant_list_indexed_files(collection="myproject", limit=50, offset=0)

# Filter by file type
qdrant_list_indexed_files(collection="myproject", file_type=".py")

# Compare Qdrant state with filesystem
qdrant_diff_collection(collection="myproject", repo_path="/path/to/repo")

OpenCode Skill

The project includes an OpenCode skill for natural language management of Qdrant.

Installation

# Copy skill to OpenCode skills directory
cp -r skills/qmcp-manager ~/.config/opencode/skills/

Usage

Once installed, OpenCode will automatically activate the skill when you ask questions like:

Query	What Happens
what's indexed in my Qdrant?	Diagnoses collection and shows stats
show collection stats	Lists all collections with vector counts
clean up orphans in my index	Finds and previews deletion of orphaned vectors
diagnose my index	Full diagnostics with issues and file list
compare index with /path/to/repo	Shows orphans, missing, and modified files
find missing files	Lists files on disk but not indexed
is my index up to date?	Compares hashes to detect changes

Workflows Provided by Skill

1. Quick Status - Check collection state with qdrant_list_collections
2. Full Diagnostics - Detailed analysis with qdrant_diagnose_collection
3. Diff - Compare Qdrant with filesystem using qdrant_diff_collection
4. Safe Cleanup - Preview with dry-run, then confirm deletion
5. Smart Reindex - Incremental updates based on file hashes
