ContextMCP Dockerized Setup

This repository wraps the upstream dodopayments/context-mcp project and provides two Docker Compose entrypoints:

• docker-compose.local.yml for fully local development with Ollama + Pinecone Local

• docker-compose.cloud.yml for app/reindex flows backed by cloud services

With new changes being made most likely it will be moved to a fork of the upstream project.

Local mode

1. Copy the example environment file:

cp .env.example .env

2. Review config.yaml and replace the placeholder source before indexing.

3. Start Pinecone Local and Ollama:

docker compose -f docker-compose.local.yml up -d pinecone ollama

4. Pull the default embedding model:

docker compose -f docker-compose.local.yml --profile bootstrap run --rm ollama-bootstrap

Alternatively, if Ollama is running directly on the host:

ollama pull nomic-embed-text

5. Run reindex:

docker compose -f docker-compose.local.yml --profile reindex run --rm reindex

6. Start the app:

docker compose -f docker-compose.local.yml up -d app

Local Pinecone backup and restore

Pinecone Local is in-memory and does not provide native backup/restore. This repository adds a repo-owned export/import workflow on top of the local API.

Because the local index is in memory, it is a good idea to create a backup right after a successful indexing run. That way you can restore the same local corpus after a reboot instead of rerunning a long reindex.

Before using the backup/restore scripts on a fresh clone, install the small host-side helper dependency:

npm install

Create a backup:

./scripts/backup-local-index.sh

This writes a new folder under ./backups/, for example:

backups/contextmcp-docs-2026-07-31T12-00-00Z/

Restore from the latest backup:

./scripts/restore-local-index.sh

Restore from a specific backup:

BACKUP_DIR=./backups/contextmcp-docs-2026-07-31T12-00-00Z ./scripts/restore-local-index.sh

Useful knobs:

• BACKUP_ROOT - where backup folders are created

• BACKUP_DIR - explicitly restore from a specific backup folder

• BACKUP_BATCH_SIZE - vectors per exported backup file

• RESTORE_INDEX_NAME - restore into a different local index name

• RESTORE_CLEAR_FIRST=false - keep existing vectors and upsert on top

• RESTORE_UPSERT_BATCH_SIZE - vectors per restore upsert request

Restore behavior notes:

• the restore script will create the target index if it does not exist

• if the target index already exists, restore validates dimension and metric compatibility before clearing anything

Local multi-repo indexing (optional)

Instead of editing config.yaml per repository, you can index an arbitrary list of local repositories by setting two variables in .env:

LOCAL_DOCS_ROOT=/absolute/path/to/your/projects
LOCAL_DOCS_REPOS=repo-one=java,repo-two=typescript:sub/path

• LOCAL_DOCS_ROOT is mounted read-only into the reindex container at /workspace/repos.

• LOCAL_DOCS_REPOS is a comma-separated list of repo=language pairs. Each repo must be a subdirectory name under LOCAL_DOCS_ROOT. language must be one of java, typescript, or javascript. You can optionally append a repo-relative subpath after the language (repo=language:sub/path) when the actual source code lives below the repo root, for example Hybris=java:hybris/bin/custom.

• Each repo is indexed as one mixed source set: the AST-aware parser: code chunker extracts method/function/class chunks from code files and whole-file chunks from text-like config/infra files (for example yaml/yml/json/ properties/xml/toml/conf/cfg/ini, shell scripts, Dockerfiles, and common dot-config files such as .gitignore, .dockerignore, .editorconfig). Common build/tooling directories are still skipped (.git, node_modules, build, .gradle, .idea, etc.).

• When LOCAL_DOCS_REPOS is unset, this feature does nothing and reindex falls back to the source configured in config.yaml, unchanged.

Run it the same way as the standard local flow:

docker compose -f docker-compose.local.yml --profile reindex run --rm reindex
docker compose -f docker-compose.local.yml up -d app

Cloud mode

1. Copy the example environment file:

cp .env.example .env

2. Change .env for cloud usage:

• set PINECONE_MODE=cloud

• set PINECONE_API_KEY to your real key

• clear PINECONE_CONTROLLER_HOST

• set OPENAI_API_KEY, or update config.cloud.yaml to a different embedding provider before setting that provider's key

3. Review config.cloud.yaml and replace the placeholder source before indexing.

4. Run the cloud reindex/app flow:

docker compose -f docker-compose.cloud.yml --profile reindex run --rm reindex
docker compose -f docker-compose.cloud.yml up -d app

Notes

• Pinecone Local is development-only.

• Pinecone Local is in-memory and not production-safe.

• Pinecone Local records do not persist after shutdown.

• The Docker image vendors upstream ContextMCP v0.5.0 and applies a small local-support patch at build time.
