Magic MCP vs SolvScore
A side-by-side look at the Magic MCP and SolvScore MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Magic MCP for developer tools work as a local process; choose SolvScore for developer tools over a hosted endpoint. You can also run both side by side in one mcpServers block.

SolvScore tools 20
get_solvscore_agent_dashboard[FREE] SolvScore Agent Credit Dashboard (inv #4345): browse scored AI agents with filters — trust score range (0-100), reputation bond status (active|slashed), job, and sort (trust_score|credit|apr|name). Returns trust score, credit limit, APR, badges, bond status and profile links per agent. Snapshot re-scored every 6h.get_agent_credit_score[FREE] Look up an AI agent's SolvScore credit file before you transact with it. Accepts an agent name, id, or Base L2 wallet address. Returns trust_score (0-100), badges (reputation bonds held), a nested credit object carrying credit_limit and apr_bps, plus two counterparty red flags worth checking before you extend anything: sybil_flagged and cooling. Free and unauthenticated - no API key, no payment header.underwrite_agent_loan[FREE] Get a real underwriting decision on a loan to an AI agent. principal = requested loan size in USDC. tier1_value = optional collateral pledged in USDC (Coinbase B20 tokenized stocks or USDC on Base). Posting collateral moves the agent from the reputation tier to the hard tier: higher limit, lower APR. Returns approved (true/false), credit_limit_usdc, apr_pct, tier and a plain-language reason. Roughly half of all requests are declined, so treat a decline as real signal.register_agent[FREE] Open a SolvScore credit file for your own agent so it can be underwritten. Call this once before requesting credit, or whenever a score lookup returns no_such_agent: an agent must hold a credit file before the bureau will rate it. agent_name = the name your agent is known by (2-64 chars: letters, digits, space, dot, dash, underscore). wallet = optional Base L2 address as 0x followed by 40 hex characters. Supplying a wallet that already matches an agent with verified AgentWorld work history links that history to the new file immediately, so the file opens with real capacity instead of zero. harness = the framework running the agent: claude, chatgpt, codex, cursor, langchain, crewai, autogen, mcp, custom or other. contact = optional email or URL the bureau can reach you at. Returns credit_file_id, which you then pass as `agent` to get_agent_credit_score and underwrite_agent_loan, plus the opening state and next steps. Registration is idempotent: the same name or wallet returns the existing file rather than creating a duplicate. Expect a thin file. With no verified history a new agent opens at a 0 USDC reputation limit and the maximum APR, exactly as a credit bureau treats a borrower with no record. Two paths raise it: post collateral through underwrite_agent_loan's tier1_value to borrow on day one, and accrue verified completed work to earn reputation capacity. Free and unauthenticated - no API key, no payment header.
