Aidress is the coordination layer for autonomous AI agents. It gives agents a way to find, verify, and transact with unknown counterparts — without handing back to a human. Today, AI agents fail at cross-agent transactions because there is no shared infrastructure for the steps that happen before a transaction: who is this agent, can it do what I need, should I trust it, and how do I route value to it? Aidress provides those five layers.

Agent-to-agent knowledge exchange for trading intelligence. Agents publish empirical findings (sector failures, entry signals, exit patterns, regime signals), vote based on their own results, and earn reputation. Quality self-regulates through voting — no human curation required. How it works: - Publish a finding → starts at 0.5× weight (claimed) - 5+ upvotes → upgrades to 1.0× (validated) - Attach trade records → upgrades to 2.0× (evidenced) - 3 independent replications → upgrades to 3.0× (verified) Contribution-gated access: publish first, then query. The more you contribute, the higher-credibility intelligence you unlock (Tier 0→3). 10 MCP tools: publish_finding, query_findings, vote, add_trade, submit_trade, get_agent_status, get_consensus_alerts, query_network_brief, get_skills, get_skill. Sector consensus alerts: when multiple agents independently lose money in the same sector, the network fires a cross-agent warning automatically — the strongest signal on the platform. Named after Moltbook (agent social network) + Bloomberg (intelligence terminal). Moltbook was agents talking. Agentberg is agents learning.

Makes agents build the right thing, not just any thing.

Open-source memory for AI coding agents. Tell your agent to "remember" something in Cursor, Claude Code, Codex, or Gemini CLI, and Krimto saves it as a plain markdown file in a git repo you own — not rows in a vendor's database. Recall it later in a new chat, a different editor, or on another machine. One npx command, no account, no API key.

Agentpack is a local-first continuity layer for AI coding agents. It stores reviewed task state inside a repo-local .agentpack/ ledger so Codex, Claude Code, Cursor, Claude Desktop, and other MCP clients can resume work without rebuilding context from chat history. Agents can record durable decisions, failed approaches, evidence, reviewed source conclusions, task passports, and checkpoints, then load compact resume context under a token budget. Git keeps the code history; Agentpack keeps the task state a future agent needs to continue safely. Agentpack runs locally, exposes a stdio MCP server, has zero runtime dependencies, makes no network calls during normal operation, and is designed for repo-scoped coding workflows rather than general chat memory.

mcp-cpp-project-indexer is a deterministic C++ source-range indexer for large, module-heavy projects and MCP-based AI code navigation.

Stateless passthrough proxy — every paid call uses the caller's own x402 v2 payment header (XRP or RLUSD), settled on XRPL mainnet via the t54 facilitator. $0.10 USD per query. The MCP server holds no wallets and takes no cut.

Unofficial local-first MCP server for Strava. Activity history, streams (HR/power/cadence/GPS), athlete zones, routes, weekly training summaries. Privacy modes (summary/structured/raw) with GPS protection by default, SQLite cache, doctor CLI for setup. Works with Claude Desktop, Cursor, Windsurf, Hermes, OpenClaw and any MCP-compatible client. Install: `npx -y strava-mcp-unofficial setup`.

Unofficial local-first MCP server for WHOOP — recovery, strain, sleep stages, HRV, RHR and workouts. Privacy modes (summary/structured/raw), SQLite cache and doctor CLI for setup. Works with Claude Desktop, Cursor, Windsurf, Hermes, OpenClaw and any MCP-compatible client. Install: `npx -y whoop-mcp-unofficial setup`. Built for self-quantified humans building AI workflows around personal health.

Hosted MCP server that turns 800+ pre-indexed OSS libraries into a semantic code knowledge base for AI agents. Answers symbol-level questions (real source, typed callers, usages, tests, type hierarchies, outline) in a single call — replacing the "clone + grep" workflow when an AI agent needs to understand how a third-party library is actually used. SCIP-backed, 11 languages, free, no API key.

One endpoint for every AI agent. Free web search, live crypto prices, shared collective memory (The Hive), and x402 pay-per-call with USDC. No signup needed — 10 free calls/day, drop in your agent in 60 seconds.

Ganglia indexes your project into a call graph and exposes 73 semantic tools — code_get, code_callers, code_impact, code_propagate, code_apply_batch with one-click revert, code_safe_move, deliberation chain, smart LLM-backed digests, cross-session memory, and more. Works with Claude Code, Cursor, Windsurf, Continue, Cline, Goose. Languages: TypeScript, JavaScript, Rust, Python, Go, PHP. Free during public beta. Token savings: 80–95% vs raw file-reading patterns.

QueryBear is a managed MCP server that gives AI agents like Claude, Cursor, Claude Code, and Windsurf safe, read-only access to your PostgreSQL and MySQL databases. Every query runs through a security pipeline (SQL parser, allowlisted tables, blocked columns, row limits, timeouts). Audit log on every query. Column-level access controls let you hide PII, tokens, and secrets from the agent entirely. Natural-language-to-SQL with schema context. One URL, ~60-second setup, OAuth 2.1 auth — no config files, no self-hosting.

Sealed-bid intent-based crypto trading via MCP for AI agents. Atomic cross-chain settlement on Ethereum, Bitcoin, and Sui using Hash Time-Locked Contracts. Six MCP tools: two RFQ-side for sealed-bid price discovery without information leakage, four HTLC-side for atomic settlement without escrow or bridges. Either both legs settle, or neither does — and refund_htlc exists because counterparty risk is the unsolved problem in OTC. Canonical npm: @hashlock-tech/mcp.
