How do I use project management or custom memory types in mcp-memory-service?

Question

I want to store project management artifacts (sprint goals, retrospectives, milestones, stakeholder requirements) in mcp-memory-service (doobidoo/mcp-memory-service), but the memory_type ontology only had software-development types like observation, decision, and pattern. Is there a way to use non-developer memory types or define my own?

Implemented in v10.12.0, released 2026-02-14. The `memory_type` ontology now includes project management and general knowledge work types, so the developer-only limitation described in the issue is gone.

From the maintainer's release notes:

1. Upgrade the package:
   ```bash
   pip install --upgrade mcp-memory-service
   ```

2. v10.12.0 expands the ontology from 29 to 75 total memory types:
   - 12 Agile PM types
   - 12 Traditional PM types
   - 18 Knowledge Work types

3. The existing types were kept unchanged, so the release is fully backward compatible with previously stored memories.

4. For types not covered by the built-in set, custom type extension is supported through the `MCP_CUSTOM_MEMORY_TYPES` environment variable.

General advice: the thread does not include an example value for `MCP_CUSTOM_MEMORY_TYPES`, so check the v10.12.0 CHANGELOG entry to confirm the exact format the variable expects before adding it to your MCP server configuration.
