### Connect to Server Logic (TypeScript)

Source: https://context7_llms

Implements the logic for connecting to a server by fetching MCP details from the registry and spawning an aggregator using its manifest configuration. It supports dynamic command, arguments, and environment variable setup.

```typescript
async function connectServer(slug: string) {
  const { mcps } = await fetch(`https://onlyonemcp.com/registry?q=${slug}`).then(r => r.json());
  const target = mcps[0];
  
  // Implementation pattern for Stdio bridge
  const config = {
    command: target.manifest.command || 'npx',
    args: target.manifest.args || ['-y', target.slug],
    env: target.manifest.env || {}
  };
  
  return spawnAggregator(config);
}
```

### HTTP Caching Headers Example

Source: https://context7_llms

Specifies HTTP caching headers for client-side caching of registry data. It uses `Cache-Control` with `public`, `max-age`, and `stale-while-revalidate` to optimize data freshness and reduce server load.

```http
Cache-Control: public, max-age=300, stale-while-revalidate=3600
```

### GET /registry - Real-Time Monitoring & Webhooks

Source: https://context7_llms

Monitor the registry for changes using high-performance conditional requests. Clients can leverage the `If-None-Match` header with the `ETag` returned in previous responses to efficiently fetch only updated data.

```APIDOC
## GET /registry - Real-Time Monitoring

### Description
Monitor the registry for changes using high-performance conditional requests. Clients can leverage the `If-None-Match` header with the `ETag` returned in previous responses to efficiently fetch only updated data.

### Method
GET

### Endpoint
`/registry`

### Query Parameters
(See GET /registry - Discover MCP Servers)

### Request Headers
- **If-None-Match** (string) - Optional - The ETag value from a previous response to check for changes.

### Response
#### Success Response (200)
- **ETag** (header) - The current ETag for the registry response.
- **mcps** (array) - An array of MCP server objects (if changes detected).

#### Not Modified Response (304)
- Returned if the registry has not changed since the last request (indicated by `If-None-Match` header matching the current ETag).

#### Response Example (200 OK)
```json
{
  "mcps": [
    // ... updated MCP server data ...
  ]
}
```
```

        ],
        "version": "1.0.0"
      },
      "installCount": 123
    }
  ]
}
```
```

--------------------------------

### Client-Side Filtering Logic (TypeScript)

Source: https://context7_llms

Demonstrates advanced client-side filtering of MCPs based on tool descriptions or category inclusion. This allows clients to efficiently narrow down the list of available MCPs to match specific requirements.

```typescript
const filtered = allMcps.filter(mcp => 
  mcp.manifest.tools.some(t => t.description.includes('analytics')) ||
  mcp.categories.includes('marketing')
);
```

--------------------------------

### Registry API Response Schema (TypeScript)

Source: https://context7_llms

Defines the structure of the response from the OnlyOneMCP registry API, detailing MCP properties like ID, slug, name, description, verification status, manifest, and installation count. This schema is crucial for clients interacting with the registry.

```typescript
interface RegistryResponse {
  mcps: {
    id: string;          // UUID
    slug: string;        // URL-friendly identifier
    name: string;        // Human-readable name
    description: string; // Detailed capability overview
    verifiedStatus: 'official' | 'verified' | 'unverified';
    manifest: {
      tools: Array<{ 
        name: string;
        description: string;
        inputSchema: object; // Zod or JSON Schema
      }>;
      version: string;   // SemVer
    };
    installCount: number; // Current usage metric
  }[];
}
```

--------------------------------

### Synchronize Connections with TypeScript

Source: https://context7_llms

Implements a connection synchronization mechanism using TypeScript. The ConnectionManager class maintains a set of active connection IDs and synchronizes them against a list of expected slugs, identifying connections to be killed and started. This pattern is useful for managing dynamic sets of resources.

```typescript
class ConnectionManager {
  private activeIds = new Set<string>();
  
  async sync(expectedSlugs: string[]) {
    const toKill = [...this.activeIds].filter(id => !expectedSlugs.includes(id));
    const toStart = expectedSlugs.filter(slug => !this.activeIds.has(slug));
    // ... orchestrate kill and start hooks
  }
}
```

--------------------------------

### Federated Discovery Logic (TypeScript)

Source: https://context7_llms

Implements a federated search strategy that prioritizes local discovery sources before delegating requests to the OnlyOneMCP registry for unknown server types. This ensures comprehensive discovery across multiple systems.

```typescript
const DISCOVERY_PRIORITY = ['local', 'onlyonemcp'];

async function federatedSearch(query: string) {
  for (const source of DISCOVERY_PRIORITY) {
    const result = await checkSource(source, query);
    if (result.length > 0) return result;
  }
  return [];
}
```

--------------------------------

### POST /registry/{slug}/connect - One-Click Connection

Source: https://context7_llms

Initiates a one-click connection to an MCP server using its slug. This logic involves fetching the MCP manifest from the registry and establishing a connection, typically via a Stdio bridge.

```APIDOC
## POST /registry/{slug}/connect

### Description
Initiates a one-click connection to an MCP server using its slug. This involves fetching the MCP manifest from the registry and establishing a connection, typically via a Stdio bridge.

### Method
POST

### Endpoint
`/registry/{slug}/connect`

### Parameters
#### Path Parameters
- **slug** (string) - Required - The unique slug of the MCP server to connect to.

### Request Body
(No request body specified, relies on path parameter)

### Response
#### Success Response (200)
- (Details of connection establishment response, e.g., connection status or client object)

#### Response Example
```json
{
  "status": "connected",
  "clientId": "unique-client-id"
}
```
```

--------------------------------

### Connection Validation Function (TypeScript)

Source: https://context7_llms

Provides a function to validate the health and functionality of a connection to an MCP client. It attempts to list tools with a timeout and returns the connection status as 'functional', 'degraded', or 'unreachable'.

```typescript
async function validateConnection(client: McpClient) {
  try {
    const timeout = AbortSignal.timeout(5000);
    const { tools } = await client.listTools({ signal: timeout });
    return tools.length >= 0 ? 'functional' : 'degraded';
  } catch (err) {
    return 'unreachable';
  }
}
```

--------------------------------

### Real-Time Registry Monitoring (TypeScript)

Source: https://context7_llms

Sets up a polling mechanism to monitor the registry for changes using high-performance conditional requests with ETags. It fetches updates at a regular interval and updates a local cache if new data is available.

```typescript
let lastETag = '';
async function pollRegistry() {
  const res = await fetch('/registry', { headers: { 'If-None-Match': lastETag } });
  if (res.status === 200) {
    lastETag = res.headers.get('ETag');
    updateLocalCache(await res.json());
  }
}
setInterval(pollRegistry, 60000); // 1-minute window
```

--------------------------------

### POST /connections/{clientId}/validate - Connection Validation & Health Protocol

Source: https://context7_llms

Validates the health and functionality of a connected client. This endpoint checks if the client can list its tools within a specified timeout, returning its status as 'functional', 'degraded', or 'unreachable'.

```APIDOC
## POST /connections/{clientId}/validate - Connection Validation & Health Protocol

### Description
Validates the health and functionality of a connected client. This endpoint checks if the client can list its tools within a specified timeout, returning its status as 'functional', 'degraded', or 'unreachable'.

### Parameters
#### Path Parameters
- **clientId** (string) - Required - The identifier of the client connection to validate.

#### Response Example
```json
{
  "status": "functional"
}
```
```
