**Title:** Implement prompt link resolution service
|
||
|
|
|
||
|
|
**Status:** done
|
||
|
|
|

|
|
**Dependencies:** 40 ✓
|
||
|
|
|
||
|
|
**Priority:** medium
|
||
|
|
|
||
|
|
**Description:** Create a service that fetches linked prompt content from source MCP servers using the project's service account, with dead link detection.
|
||
|
|
|
||
|
|
**Details:**
|
||
|
|
|
||
|
|
1. Create `/src/mcplocal/src/services/link-resolver.service.ts`:
|
||
|
|
```typescript
|
||
|
|
export class LinkResolverService {
|
||
|
|
constructor(private mcpdClient: McpdClient) {}
|
||
|
|
|
||
|
|
async resolveLink(linkTarget: string): Promise<{
|
||
|
|
content: string | null;
|
||
|
|
status: 'alive' | 'dead' | 'unknown';
|
||
|
|
error?: string;
|
||
|
|
}> {
|
||
|
|
// Parse linkTarget: project/server:resource-uri
|
||
|
|
const { project, server, uri } = this.parseLink(linkTarget);
|
||
|
|
|
||
|
|
try {
|
||
|
|
// Use service account for source project
|
||
|
|
const content = await this.fetchResource(project, server, uri);
|
||
|
|
return { content, status: 'alive' };
|
||
|
|
} catch (error) {
|
||
|
|
this.logDeadLink(linkTarget, error);
|
||
|
|
return {
|
||
|
|
content: null,
|
||
|
|
status: 'dead',
|
||
|
|
error: error.message
|
||
|
|
};
|
||
|
|
}
|
||
|
|
}
|
||
|
|
|
||
|
|
private parseLink(linkTarget: string): { project: string; server: string; uri: string } {
|
||
|
|
const match = linkTarget.match(/^([^/]+)\/([^:]+):(.+)$/);
|
||
|
|
if (!match) throw new Error('Invalid link format');
|
||
|
|
return { project: match[1], server: match[2], uri: match[3] };
|
||
|
|
}
|
||
|
|
|
||
|
|
private async fetchResource(project: string, server: string, uri: string): Promise<string> {
|
||
|
|
// Call mcpd to fetch resource via service account
|
||
|
|
// mcpd routes to the source project's MCP server
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
2. Log dead links as errors
|
||
|
|
|
||
|
|
3. Cache resolution results
|
||
|
|
|
||
|
|
**Test Strategy:**
|
||
|
|
|
||
|
|
- Unit test: Valid link parsed correctly
|
||
|
|
- Unit test: Invalid link format throws error
|
||
|
|
- Unit test: Successful resolution returns content and status='alive'
|
||
|
|
- Unit test: Failed resolution returns status='dead' with error
|
||
|
|
- Unit test: Dead link logged as error
|
||
|
|
- Unit test: Service account header included in request
|
||
|
|
- Integration test: End-to-end link resolution
|
