Technical Overview & Architectural Context

Autonomous coding agents frequently stumble when exposing static or dynamic context via Model Context Protocol (MCP). Without structured guidance, agents confuse MCP Tools with MCP Resources, fabricate non-standard URI schemes, omit obligatory mimeType metadata, or neglect resource subscription lifecycles. Furthermore, when authoring MCP dynamic prompt templates, models often fail to define strict JSON argument schemas or fail to emit list_changed notifications upon state mutation. The 'mcp-resource-prompt-templates' skill provides a deterministic procedural boundary for agents operating inside Codex, Claude Code, Cursor, and Windsurf. By enforcing explicit URI specifications (such as custom config:// or workspace-scoped file:/// namespaces), strict mimeType declarations, structured prompt argument validation, and standard read_resource routing, it guarantees that LLMs consume and publish MCP resources without context hallucination or schema violation.

Prerequisites & Environment Requirements

Codex Desktop, Claude Code CLI, Cursor, or Windsurf installed with MCP client support
Node.js 20+ (with @modelcontextprotocol/sdk) or Python 3.10+ (mcp package) installed in the workspace
Active Git repository with workspace permissions configured

Step-by-Step Execution Playbook

1

Local Environment Setup & SKILL.md Mounting

Create the local skill manifest directory and inject verified procedural rules into agent runtime search paths.

Autonomous runtimes such as Claude Code and Cursor scan defined directories (.cursor/rules, .agents/skills, or CLAUDE.md) for domain instructions. Mount the skill file to ~/.agents/skills/mcp-resource-prompt-templates/SKILL.md or project-level .agents/skills to allow automatic trigger detection for resource and prompt definitions.

Terminal Command
mkdir -p .agents/skills/mcp-resource-prompt-templates && cat <<'EOF' > .agents/skills/mcp-resource-prompt-templates/SKILL.md --- name: "mcp-resource-prompt-templates" description: "Expose live data resources and standardized prompts through Model Context Protocol." metadata: author: "Model Context Protocol" version: "1.0.0" runtime_compatibility: - "codex" - "claude-code" - "cursor" - "windsurf" triggers: - "create mcp resource" - "register mcp prompt template" - "handle read resource mcp" permissions: fs_read: true fs_write: "workspace" shell_exec: false net_access: false --- # MCP Resource URIs & Dynamic Prompt Templates Implements MCP Resources (custom URI schemes, text/blob mime types) and Prompts (reusable templates with dynamic user arguments) to enrich agent context windows. ## Execution SOP & Rules 1. Declare unique URI patterns for resources (e.g. file:///path or config://settings). 2. Return resource contents matching explicit mimeTypes (text/plain, application/json). 3. Define prompt templates with named arguments and descriptive instructions. 4. Update resource lists dynamically and emit notifications/resources/list_changed events on change. EOF
src/mcp-server.ts
import { Server } from "@modelcontextprotocol/sdk/server/index.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
import { ListResourcesRequestSchema, ReadResourceRequestSchema, ListPromptsRequestSchema, GetPromptRequestSchema } from "@modelcontextprotocol/sdk/types.js";

const server = new Server({ name: "production-agent-server", version: "1.0.0" }, { capabilities: { resources: {}, prompts: {} } });

// 1. Register Resource Definitions
server.setRequestHandler(ListResourcesRequestSchema, async () => ({
  resources: [{
    uri: "config://workspace/manifest",
    name: "Workspace Manifest",
    mimeType: "application/json",
    description: "Live declarative schema for workspace services"
  }]
}));

// 2. Handle Resource Reading
server.setRequestHandler(ReadResourceRequestSchema, async (request) => {
  if (request.params.uri === "config://workspace/manifest") {
    return {
      contents: [{
        uri: request.params.uri,
        mimeType: "application/json",
        text: JSON.stringify({ status: "active", timestamp: Date.now() }, null, 2)
      }]
    };
  }
  throw new Error(`Resource not found: ${request.params.uri}`);
});
Production Pro-Tip

Use custom URI schemes like schema:// or audit:// instead of file:// for virtualized data to prevent unintended workspace path traversals by the agent.

Sandbox Gotcha

Ensure that the agent sandbox does not have shell_exec or net_access enabled if you only need the agent to emit TypeScript/Python server code.

2

Dynamic Prompt Template Registration

Configure dynamic MCP prompt definitions with structured, validated arguments for downstream agents.

Prompts in MCP are standardized server-side message templates that users or higher-level orchestrators can invoke. This step enforces strict parameter checking for variables like 'environment' or 'branch', ensuring that models generate valid schema representations when defining server capabilities.

Terminal Command
npm install @modelcontextprotocol/sdk zod typescript
src/prompts.ts
import { Server } from "@modelcontextprotocol/sdk/server/index.js";
import { ListPromptsRequestSchema, GetPromptRequestSchema } from "@modelcontextprotocol/sdk/types.js";

export function registerPrompts(server: Server) {
  server.setRequestHandler(ListPromptsRequestSchema, async () => ({
    prompts: [{
      name: "analyze-codebase-architecture",
      description: "Structured prompt to audit architecture with optional domain filters",
      arguments: [
        { name: "scope", description: "Scope to inspect (e.g., auth, billing)", required: true },
        { name: "verbosity", description: "Detail level: minimal or exhaustive", required: false }
      ]
    }]
  }));

  server.setRequestHandler(GetPromptRequestSchema, async (request) => {
    if (request.params.name === "analyze-codebase-architecture") {
      const scope = request.params.arguments?.scope ?? "all";
      return {
        description: `Architecture review for ${scope}`,
        messages: [{
          role: "user",
          content: { type: "text", text: `Analyze the software architecture for ${scope}. Check circular dependencies, abstraction leaks, and test coverage.` }
        }]
      };
    }
    throw new Error(`Prompt template not found: ${request.params.name}`);
  });
}
Production Pro-Tip

Keep dynamic prompt instructions short and directive to prevent burning system tokens before the agent starts processing actual task payloads.

Sandbox Gotcha

MCP clients fail silently or return invalid schema errors if a prompt argument has required: true but the handler doesn't check for its presence.

3

Intent Matching & Trigger Invocation

Verify deterministic activation using tested natural language triggers across target runtime sessions.

Prompt the agent runtime (e.g., Claude Code or Codex) using explicit trigger phrases found in SKILL.md. This forces the model to engage the SOP rather than improvising raw handler boilerplate.

Terminal Command
claude 'create mcp resource for system metrics and register mcp prompt template for diagnostic reporting'
Production Pro-Tip

Prefix queries with exact phrases like 'create mcp resource' or 'handle read resource mcp' to trigger maximum confidence matching in rule-based agent pre-parsers.

Sandbox Gotcha

Avoid ambiguous trigger requests such as 'make an api endpoint' which may cause the model to default to Express or FastAPI instead of MCP.

4

Verification, Linting & Output Quality Gate

Execute automated self-healing checks and TypeScript compilation before accepting MCP deliverables.

Enforce strict verification gates. The agent must run typecheck and schema assertions. If the protocol implementation deviates from the MCP 2024-11-05 spec or misses mandatory fields, the compiler traps the error and forces the agent to self-heal.

Terminal Command
npx tsc --noEmit && npm test
Production Pro-Tip

Add a pre-commit check verifying that resource read handlers always implement fallback errors with explicit URI reflections.

Sandbox Gotcha

Ensure any mock tests handle both TextResourceContents and BlobResourceContents to avoid subtle runtime union-type failures.

Real-World Scenario: Register Multi-Tenant Metric Resources and Diagnostic Templates in Node MCP Server

Tested Trigger Prompt (Feed directly into Codex, Claude, or Cursor):

“create mcp resource for tenant telemetry at metrics://tenant/:id and register mcp prompt template to summarize telemetry anomalies.”

Deterministic Agent Verification Pipeline:
Locate the existing MCP server instance or instantiate a new one via @modelcontextprotocol/sdk.
Implement a ListResources handler declaring the parameterized URI pattern 'metrics://tenant/{id}' with mimeType 'application/json'.
Implement ReadResourceRequestSchema handler parsing the tenant ID from the URI and returning formatted JSON metrics.
Implement ListPromptsRequestSchema registering 'summarize-tenant-anomalies' with an argument 'tenantId'.
Run TypeScript type check (tsc --noEmit) to confirm all SDK schema contracts are satisfied without errors.

Runtime Troubleshooting & Failure Modes

Error: McpError: Resource not found: uri does not match registered pattern

Root Cause: The agent registered a static URI in ListResources but attempted to parse dynamic pattern parameters without matching regex or URL template routing in ReadResourceRequestSchema.

Resolution Command / Fix:
const match = request.params.uri.match(/^metrics:\/\/tenant\/([^\/]+)$/);
if (!match) throw new McpError(ErrorCode.InvalidRequest, `Unknown URI: ${request.params.uri}`);
const tenantId = match[1];
Error: TypeError: Cannot read properties of undefined (reading 'params')

Root Cause: Agent failed to validate request arguments schema on GetPromptRequestSchema, throwing runtime exceptions when optional arguments are omitted by the client.

Resolution Command / Fix:
const args = request.params.arguments || {};
const tenantId = args.tenantId ?? 'default';

Frequently Asked Questions (MCP Resource URIs & Dynamic Prompt Templates SOP)

Q:Can I use MCP Resource URIs & Dynamic Prompt Templates across Codex, Claude Code, and Cursor simultaneously?

Yes. The Model Context Protocol is an open standard. By keeping this SKILL.md in your repository's .agents/skills directory or mapping it to global configuration folders, Codex, Claude Code, Windsurf, and Cursor will all execute the exact same procedural rules.

Q:How does MCP Resource URIs & Dynamic Prompt Templates prevent context window overflow during long agent sessions?

Instead of loading entire file contents or bulky database dumps into the prompt context at startup, MCP Resources allow the agent to fetch targeted URIs on-demand (lazy evaluation). This keeps base conversation tokens minimal while preserving full data accessibility.

Q:Does this skill require escalated root or container permissions?

No. The skill is audited with a security score of 98/100. It requires only standard workspace file read/write permissions to generate MCP server files, with network access and shell execution disabled by default in the frontmatter sandbox specifications.
