mcp-eregistrations 1.21.1

MCP servers for eRegistrations platform (BPA + GDB + Keycloak + SmartLink)

MCP eRegistrations

AI-powered administration for eRegistrations platforms.

A monorepo of six MCP servers that let Claude (and any MCP-compatible client) manage service design, runtime data, databases, identity, translations, and logs on eRegistrations deployments through natural language.

You: Scan the Jamaica service abc-123 for config issues
Claude: Found 144 issues — 67 orphaned effects (HIGH), 18 orphaned determinants (HIGH), 33 translation issues...

You: Fix the high-severity ones
Claude: Phase 1: Delete 67 orphaned effects. Phase 2: Delete 18 determinants. Proceed? [waits]

Each write operation is audited with per-instance rollback state.

Packages

Package	Entry point	Scope	Tools
mcp_eregistrations_bpa	mcp-eregistrations-bpa	Service design (read + write)	~176
mcp_eregistrations_gdb	mcp-eregistrations-gdb	Generic DB builder (read + write)	~63
mcp_eregistrations_keycloak	mcp-eregistrations-keycloak	IAM admin (read + write)	~51

Common helpers live in mcp_eregistrations_common/ (instance profiles, shared auth, config resolution).

Installation

Plugin marketplace (recommended)

claude plugins marketplace add unctad-digital-government
claude plugins install bpa-mcp@unctad-digital-government           # Service design
claude plugins install gdb-mcp@unctad-digital-government           # Databases
claude plugins install keycloak-mcp@unctad-digital-government      # IAM
claude plugins install ds-mcp@unctad-digital-government            # Runtime monitoring
claude plugins install translations-mcp@unctad-digital-government  # Translations (authoring + governance)
claude plugins install graylog-mcp@unctad-digital-government       # Logs

Restart Claude Code, then register your instances:

/bpa-mcp:install              # walks you through adding your first profile
/bpa-mcp:login jamaica        # authenticate once, shared across all servers

Update with claude plugins marketplace update unctad-digital-government then reinstall — a marketplace bump alone does not refresh already-installed plugins.

Direct (uvx)

claude mcp add --scope user --transport stdio BPA-jamaica \
  -- uvx --from mcp-eregistrations@latest mcp-eregistrations-bpa

Then register the instance at runtime — environment variables are only used to bootstrap the default instance; all other profiles are stored in ~/.config/mcp-eregistrations-bpa/profiles.json and registered via the instance_add tool.

Other MCP clients

For OpenCode, the config schema and keys differ from Claude Code's. See INSTALL-OPENCODE.md for the opencode.json block, a ready-to-paste install prompt, and the schema differences you need to know.

Multi-instance, shared auth

One server process can target any number of eRegistrations instances. Every tool accepts an optional instance parameter:

You: List services in Nigeria
Claude: [service_list(instance="nigeria")]

You: Same thing in Jamaica
Claude: [service_list(instance="jamaica")]

Profiles hold their own BPA URL, Keycloak (or CAS) settings, token store, audit log, and rollback state. Credentials saved via auth_login are reused silently in future sessions — and shared across the BPA, DS, and GDB servers via the OS keyring.

Auth providers, auto-detected from the profile:

Provider	When
Keycloak	Modern deployments — OIDC + password grant (default)
CAS	Legacy (e.g. Cuba test) — OAuth2 + Basic Auth

Keycloak password grant requires Direct Access Grants enabled on the client. CAS requires a registered OAuth client with redirect URI http://127.0.0.1:8914/callback.

Key features

• Audit trail — every write goes through audit_list / audit_get; state is persisted in SQLite under each profile's data directory.
• Rollback — most write tools produce an audit ID that rollback can reverse.
• Large-response truncation — list tools gate output at ~50 KB and emit navigation hints instead of dumping raw JSON.
• Conventional annotations — every tool is tagged READ, WRITE, or DESTRUCTIVE; clients can enforce approval policies.
• Arazzo workflows (BPA) — higher-level orchestrations loaded from YAML. Available in dev checkout under _bmad-output/arazzo-workflows/; not shipped in the wheel.

Development

git clone https://github.com/UNCTAD-eRegistrations/MCP_eRegistrations.git
cd MCP_eRegistrations
uv sync

uv run pytest                          # ~3600 tests, <2 min
uv run pytest tests/test_ds/ -v        # single package
uv run ruff check . && uv run ruff format .
uv run mypy src/

Running a server locally

uv run mcp-eregistrations-bpa
uv run mcp-eregistrations-keycloak
# etc.

Then point your MCP client at the stdio command. See src/mcp_eregistrations_*/CLAUDE.md for instance configuration specific to each server.

Releasing

./scripts/release.sh patch        # 1.16.8 → 1.16.9
./scripts/release.sh minor --yes  # non-interactive

The script runs ruff, mypy, and pytest before bumping the version, generating the changelog, and creating the GitHub release. See RELEASING.md for the full flow.
