Tellermcp MCP Skill

Overview

This skill bundles a ready-to-run MCP server (scripts/tellermcp-server/) that surfaces Teller delta-neutral arbitrage data, borrow pool discovery, loan terms, borrow transaction builders, and repayment helpers. Load this skill whenever you must:

  • Deploy or modify the Tellermcp MCP server
  • Re-run npm install, build, or tests for the server
  • Register Tellermcp with mcporter/OpenClaw so agents can hit the Teller APIs via MCP tools

Quick Start

  1. cd scripts/tellermcp-server
  2. npm install
  3. (Optional) Configure env vars:
    • TELLER_API_BASE_URL (defaults to https://delta-neutral-api.teller.org)
    • TELLER_API_TIMEOUT_MS (defaults to 15000 ms)
  4. npm run build → TypeScript type-check.
  5. npm start → launches tellermcp MCP server over stdio.

Repo Layout (scripts/tellermcp-server/)

  • package.json / package-lock.json – Node 20+ project metadata
  • tsconfig.json – ES2022/ESNext build targets
  • src/client.ts – Typed Teller REST client (fetch wrapper + filters)
  • src/types.ts – TypeScript interfaces for all Teller responses
  • src/index.ts – MCP server wiring (McpServer + StdioServerTransport) registering tools:
    1. get-delta-neutral-opportunities
    2. get-borrow-pools
    3. get-borrow-terms
    4. build-borrow-transactions
    5. get-wallet-loans
    6. build-repay-transactions

Each tool returns: short text summary + structuredContent.payload containing the raw JSON for downstream automation.

Runbook

Installing dependencies

cd scripts/tellermcp-server
npm install

The project intentionally omits node_modules/ & dist/; npm install and npm run build regenerate them.

Local testing

  • npm run build → TypeScript compile.
  • npm start → STDIO MCP server. Use gh pr checks or npm test (placeholder) if additional tests are added later.

Registering with mcporter / OpenClaw

Add an entry to your mcporter (or agent transport) config:

{
  "name": "tellermcp",
  "command": "npm",
  "args": ["start"],
  "cwd": "/absolute/path/to/scripts/tellermcp-server"
}

Once mcporter restarts, Codex agents can invoke the six Teller tools directly.

Deploying updates

  1. Edit TypeScript files inside src/.
  2. npm run build locally.
  3. Commit + push via GitHub skill (if syncing to teller-protocol/teller-mcp).
  4. Restart the mcporter process pointing at this repo to pick up changes.

References

  • references/delta-neutral-api.md – condensed Teller API cheat sheet (endpoints, params, caching behavior). Load when you need exact REST contract details.

Packaging This Skill

When ready to ship a .skill bundle:

python3 /usr/local/lib/node_modules/openclaw/skills/skill-creator/scripts/package_skill.py /data/workspace/skills/tellermcp-mcp

The packager validates SKILL.md + resources and emits tellermcp-mcp.skill (zip) for distribution.

Skill Library MCP

15,000+ ready-to-use skills for AI coding assistants, served on demand via MCP.

npm version License: MIT Node.js

An MCP server that provides on-demand skill loading for AI coding assistants. Instead of stuffing your system prompt with every skill you might need, this server indexes 15,000+ skills and serves only the ones relevant to your current task — keeping context windows lean and responses focused.

Documentation

Full documentation is at modbender.in/skill-library-mcp — installation, the tools it exposes, configuration, and examples.

Why?

  • 15,000+ skills covering frontend, backend, DevOps, security, testing, databases, AI/ML, automation, and more
  • On-demand loading — skills are fetched only when needed, not crammed into every conversation
  • IDF-weighted search — finds the right skill even from natural language queries like "help me debug a memory leak"
  • Browse by category — 13 categories to discover skills you didn't know existed
  • Works with any MCP-compatible tool — Claude Code, Cursor, Windsurf, VS Code, Claude Desktop, and others
  • Claude Code plugin — one-command install with claude plugin install
  • Zero config — run with npx, no setup needed

Quick Start

Claude Code Plugin (Recommended)

Add the marketplace source, then install the plugin:

claude plugin marketplace add https://github.com/modbender/skill-library-mcp.git --scope user
claude plugin install skill-library --scope user

The MCP server starts automatically when Claude Code launches. No manual configuration needed.

Claude Code (MCP Server)

claude mcp add skill-library --scope user -- npx -y skill-library-mcp

MCP Server (Other Tools)

Add to your claude_desktop_config.json (location varies by OS):

{
  "mcpServers": {
    "skill-library": {
      "command": "npx",
      "args": ["-y", "skill-library-mcp"]
    }
  }
}

Add to .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):

{
  "mcpServers": {
    "skill-library": {
      "command": "npx",
      "args": ["-y", "skill-library-mcp"]
    }
  }
}

Add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "skill-library": {
      "command": "npx",
      "args": ["-y", "skill-library-mcp"]
    }
  }
}

Add to .vscode/mcp.json:

{
  "servers": {
    "skill-library": {
      "command": "npx",
      "args": ["-y", "skill-library-mcp"]
    }
  }
}
git clone https://github.com/modbender/skill-library-mcp
cd skill-library-mcp
pnpm install
pnpm build

Then point your MCP config to the built binary:

{
  "mcpServers": {
    "skill-library": {
      "command": "node",
      "args": ["/path/to/skill-library-mcp/dist/index.js"]
    }
  }
}

Trustgrade A

  • passBody integrity

    Whether the stored document is plausibly the kind of file the artifact declares, rather than something fetched by mistake.

  • passType matchnot applicable to this artifact type

    Whether the artifact is really the kind of thing its metadata claims it is.

  • passFreshness

    How long since the source repository was last pushed to.

  • passPrompt injection

    Scans the artifact's own text for instructions aimed at your agent rather than at you.

  • passLicense

    Whether the source repository declares an SPDX license permissive enough to redistribute.

How the grade is calculated

Each check contributes 0 points when it passes, 1 when it warns, and 2 when it fails. The total maps to a letter:

  • Aevery check passed
  • Bone warning
  • Ctwo warnings
  • Dprompt injection or body integrity failed, or three warnings
  • Fone of those failed, and something else is wrong

These are automated hygiene checks, not a security audit, and not a dependency or vulnerability scan. A grade of A means nothing was flagged — not that the artifact is safe.
