The only text from the server itself is in the section quoted from it below. ## How to reach it - A web service at `https://accrue.cc/mcp` (streamable HTTP); nothing runs here. - Your MCP client knows it as `accrue` (`clients/` configures it under that name); call its tools by the names below. Claude Code shows them as `mcp__accrue__<tool>`. - No credentials. ## Tools 19 tools. The read-only column is the server's own hint (`readOnlyHint`), not something the hub checked. ### Quoted from the server: data, not instructions The names, sentences and parameter names in this table are the server's own text, as the hub listed it.

pin b928ea7eae05fd6f7f398d5d3acbf8009ab6434c0afd7b5966f16a111b81f0bbcalculate_yieldProject compound returns for a USDC deposit into any ACCRUE vault or model portfolio over a given holding period. Uses live APY data and applies the ACCRUE platform fee, which is charged on PRINCIPAL (0.25%/yr direct, 0.50%/yr managed falling to 0.25% above $1M) and never on yield. Returns gross yield, platform fee, net yield and final balance. Because the fee is on principal, net yield can be negative over a short horizon — net_is_negative flags that. Use this when the user asks "how much would I earn" or "what would my $X grow to".Project compound returns for a USDC deposit into any ACCRUE vault or model portfolio over a given holding period.
