TypeScript MCP Sample Server
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@TypeScript MCP Sample Servergenerate a completion using gpt-4 with the prompt 'Write a function to calculate factorial'"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Sample
This is a Typescript sample for an MCP Server
Here's a tool creation example:
this.mcpServer.tool(
'completion',
{
model: z.string(),
prompt: z.string(),
options: z.object({
temperature: z.number().optional(),
max_tokens: z.number().optional(),
stream: z.boolean().optional()
}).optional()
},
async ({ model, prompt, options }) => {
console.log(`Processing completion request for model: ${model}`);
// Validate model
if (!this.models.includes(model)) {
throw new Error(`Model ${model} not supported`);
}
// Emit event for monitoring/metrics
this.events.emit('request', {
type: 'completion',
model,
timestamp: new Date()
});
// In a real implementation, this would call an AI model
// Here we just echo back parts of the request with a mock response
const response = {
id: `mcp-resp-${Date.now()}`,
model,
text: `This is a response to: ${prompt.substring(0, 30)}...`,
usage: {
promptTokens: prompt.split(' ').length,
completionTokens: 20,
totalTokens: prompt.split(' ').length + 20
}
};
// Simulate network delay
await new Promise(resolve => setTimeout(resolve, 500));
// Emit completion event
this.events.emit('completion', {
model,
timestamp: new Date()
});
return {
content: [
{
type: 'text',
text: JSON.stringify(response)
}
]
};
}
);Install

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Tool has no description.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Tool has no description.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Tool has no description.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Tool has no description.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Tool has no description.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Tool has no description.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Scored across 1 tool
With only one tool, there is no possibility of ambiguity or overlap between tools. The single tool 'completion' stands alone with no other tools to confuse it with.
A single tool inherently has perfect naming consistency, as there are no other tool names to compare it against. The name 'completion' follows a clear, simple pattern with no deviations.
A single tool is too few for a server named 'TypeScript MCP Sample Server', which suggests a broader purpose like code assistance or development tasks. One tool feels thin and insufficient for such a scope, limiting functionality.
The tool set is severely incomplete for the inferred domain of TypeScript development. With only a 'completion' tool and no description, it lacks essential operations like code analysis, refactoring, or error checking, leaving significant gaps in coverage.
