Write An OpenWiki Connector

OpenWiki connectors are built-in TypeScript modules in the OSS repository. Do not create a plugin marketplace, dynamic connector package, or runtime-loaded untrusted connector. Add normal source files and tests.

Prefer Custom MCP For Arbitrary Servers

If the knowledge source already exposes a read-only MCP server (HTTP or stdio), use the built-in custom-mcp connector instead of adding a new ConnectorId:

• Configure ~/.openwiki/connectors/custom-mcp/config.json with enabled, transport, optional allowedTools, and optional readOnlyOperations.
• Put secrets in ~/.openwiki/.env and reference them as ${ENV_NAME} in transport headers/env.
• Agent tools openwiki_list_mcp_tools / openwiki_call_mcp_tool accept custom-mcp.

Add a dedicated built-in connector only when you need provider-specific auth, scoping UI, or deterministic API pulls that MCP cannot express.

Required Shape

• Add the connector to src/connectors/types.ts and src/connectors/registry.ts.
• Implement the connector under src/connectors/sources/<connector>.ts.
• The connector must expose a ConnectorRuntime with id, displayName, description, backend, requiredEnv, supportsAgenticDiscovery, and ingest().
• Ingestion writes raw JSON/manifests under ~/.openwiki/connectors/<id>/raw/<run-id>/.
• State lives in ~/.openwiki/connectors/<id>/state.json.
• Config lives in ~/.openwiki/connectors/<id>/config.json.
• Secrets live in ~/.openwiki/.env and are referenced only by env var name.

Security Rules

• Never read, print, log, return, or hardcode secret values.
• Do not store credentials in connector config, raw files, state, logs, or tests.
• Validate connector IDs and raw file paths so reads and writes stay inside ~/.openwiki/connectors/<id>/.
• Use deterministic ingestion code for credentialed external fetching.
• If wrapping MCP, treat the MCP server as read-only and call only allowlisted read/dump operations from connector config.
• Do not let untrusted connector manifests instantiate arbitrary commands or arbitrary network endpoints without explicit built-in code review.
• For custom-mcp, users configure a reviewed built-in wrapper; still require allowedTools and/or MCP readOnlyHint before agentic tool calls (no mutating-tool heuristics beyond Notion's hosted endpoint).

Ingestion Rules

• Git/local repos should write compact manifests and let the agent inspect the local repo as the source of truth.
• Sources with timestamps should store per-stream cursors.
• Sources with object metadata should store IDs, last edited timestamps, and content hashes.
• Sources with pagination should store enough state to continue without refetching everything.
• Raw dumps should preserve source IDs, timestamps, URLs, authors, and enough provenance for citations.

User-Facing Finish

When done, tell the user:

• which connector files changed,
• which env vars to set in ~/.openwiki/.env,
• what config file to create or edit,
• how to run openwiki personal --update to trigger ingestion,
• which scopes/permissions the source provider requires.
