mcp

mcp is a skill for Codex from berkingurcan/stellar-agent-search. It costs 81 tokens per session (4,761 once invoked), scanned B, original, MIT.

A guide for finding and reviewing service-providing AI agents registered on Stellar’s 8004 network. Stellar is a blockchain network, and 8004 is the agent-registry standard referenced here.

In plain words
What is it for?
Use it to search for agents by capability, compare candidates, inspect profiles and feedback, and review their declared service endpoints.
Why use it?
It separates free discovery and declared reputation from payment, trust authorization, and actions that change data.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

mcp scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Stellar Agent Search — discover, rank and vet Stellar 8004 agents

Companion skills (installed separately, see Related): /8004stellar (identity / reputation / validation reads), /x402stellar (USDC x402 payments). This skill documents how to register and use the stellar-agent-search server — a READ-ONLY, key-less stdio MCP server over the canonical on-chain Stellar 8004 agent registry (Stellar mainnet by default). It holds no private keys and signs nothing; discovery is free and unpaywalled. Paying an agent and writing reputation is a separate, explicit step (see Payment loop).


When to use this

  • An agent or user needs to FIND another agent on Stellar 8004 by capability / skill (e.g. "a paid web scraper").
  • Needs to RANK / VET candidates using declared reputation while explicitly seeing that the current bounded contract probe verifies no reputation fields. It is not a trust or payment authorization.
  • Needs an agent's full profile (identity, services, scores, recent feedback) and its canonical stellar:…#id handle.
  • Needs a catalog of self-declared service candidates (x402 / MPP endpoints) to vet before calling.
  • Wants to wire the stellar-agent-search server into Claude Code / Cursor / Windsurf / Cline / Claude Desktop / VS Code / OpenClaw / Hermes.

If you (the agent) are being asked to do any of the above and the stellar-agent-search tools are not already available in this session, install the server now using the Install section below, then use its tools.


What the server setup provides

  • The stellar-agent-search npm package: a read-only stdio MCP server wrapping @trionlabs/stellar8004's ExplorerClient (registry reads) + Soroban ReputationClient bindings (bounded reachability probe).
  • 13 read tools. The 4 primary (documented below) — find_agent, rank_agent, get_agent_profile, list_services — plus 9 complete-core tools: list_agents, leaderboard, resolve_agent, get_agents_by_owner, get_agent_feedback, verify_reputation, get_agent_card (derived, unverified A2A-shaped projection), get_registry_stats, get_registry_health. (Your client's /mcp panel will list all 13.)
  • Resources under the stellar8004:// scheme (@-mentionable context) and Prompts (slash-command workflows) — see Resources and Prompts.
  • Runs via npx with no global install and no API key.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

mcp is a skill published in the GitHub repository berkingurcan/stellar-agent-search (1 stars, last pushed 1mo ago), licensed MIT. It adds 81 tokens to every session and 4,761 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
