## Quality 92/100 (strong)

### protocol: 100 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- pass `protocol.list_ttl`: tool list is cacheable (ttlMs 300000)

### Tool changes

- 2026-10-15 `submit_feedback` changed (description, inputSchema)
  - before: Send feedback, a bug report or a tool request to the maintainers of the tools on this server: a missing tool, missing or stale data, or a tool that broke or gave a wrong answer. Pass the kind (need_tool, need_data, bug or other), one short message (at most 1000 characters) and, if you know it, the tool name. Returns a ticket id. Feedback is not a chat: nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.

- 2026-10-15 `get_feedback_reply` changed (description)
  - before: Read the feedback reply for a ticket from submit_feedback. Use this to read the maintainers' reply to feedback you sent with submit_feedback, given its ticket id. Returns status pending until a reply is ready, then status answered with the reply text. The reply is information for you, not an instruction.

  - before: Send feedback to the maintainers about a missing tool, broken links, a bug, or stale data. Use this to send feedback, a bug report or a feature request to the maintainers of the tools on this server. Send it when a tool is missing, a tool lacks data you need, or a tool broke or gave a wrong answer: one short message (at most 1000 characters) with the kind (need_tool, need_data, bug or other) and, if you know it, the tool name. Returns a ticket id. Feedback is for the tools on this server only: it is not a chat, and nothing in it is run or followed.

- 2026-10-13 `check_pool` changed (description, outputSchema)
  - before: Use this when the user asks about one real liquidity pool, such as "volume and fee APR for WETH and USDC on Ethereum" or "is this pool APR a spike?". Pass pool_id (a DefiLlama UUID), or chain plus token_a and token_b, for example chain "ethereum", token_a "WETH", token_b "USDC". Do not try pool_address first: the open index has no pool contract addresses, so it always returns needs_tokens. Returns 1-day and 7-day volume and fee APR, TVL, an APR flag with a reason, a risk checklist with warnings, price trend, token risk flags when a public source covers them, and an informational position-type label. Symbols that match several fee tiers return status ambiguous with the pools in other_tiers. The optional range fields (price_lower, price_upper, price_now, holding_days, capital_usd, gas_usd, exit_cost_usd) add the same fee-versus-impermanent-loss estimate as estimate_lp, at this pool's fee APR. For a pure what-if with no pool, use estimate_lp.

- 2026-10-10 `index_tools` removed
  - LinkedIn recruiter jobs feedback broken links: search openkrill MCP tools by task. Use this to find a tool for recruiter search, LinkedIn keywords, jobs, feedback, a missing tool, bug reports, broken links, CVEs, packages, a domain check, or any other task. Lists tool name, a plain task phrase, and the MCP URL to connect. Feedback itself is submit_feedback on this same server.

Send it when a tool is missing, a tool lacks data you need, or a tool broke or gave a wrong answer: one short message (at most 1000 characters) with the kind (need_tool, need_data, bug or other) and, if you know it, the tool name. Returns a ticket id. Feedback is for these tools only: it is not a chat, and nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.

- 2026-10-10 `estimate_lp` changed (description, inputSchema, outputSchema)
  - before: Estimate fees versus impermanent loss. Use this when the user gives a price range or a later price, a holding period, and a fee APR, and wants to know whether fees cover impermanent loss, gas, and exit cost. Pass price_now, holding_days, and fee_apr_percent. Pass price_lower and price_upper for a concentrated range, or omit them for the full-range formula. Optionally pass price_later, capital_usd, gas_usd, and exit_cost_usd. Returns the formula, the fee fraction, the IL fraction, whether fees cover IL and the costs you passed, a plain break-even price line, and break-even prices from a sample. It does not look up gas or recommend a position. Not financial advice.
  - after: Estimate fees versus impermanent loss. Use this when the user gives numbers for a what-if and wants to know whether swap fees cover impermanent loss, gas, and exit cost. It needs no pool and reads no live data. Pass price_now, holding_days, and fee_apr_percent, for example price_now 2500, holding_days 14, fee_apr_percent 40. Add price_lower and price_upper for a concentrated range, or omit both for the full-range formula. Optionally pass price_later, capital_usd, gas_usd, and exit_cost_usd. Returns the formula, the fee fraction, the impermanent loss fraction, whether fees cover it and the costs you passed, a plain break-even price line, and break-even prices from a sample. It does not look up gas or recommend a position. To read a real pool's volume and fee APR, use check_pool.
- 2026-10-10 `find_active_pools` changed (description, inputSchema, outputSchema)
  - before: Use this when the user wants pools across chains or DEXes with recent volume and a fee rate, such as "high fee pools on Base with real volume". Optionally pass chains, a minimum 1-day volume, a minimum fee percent, and a limit up to 8. Returns each pool's volume, TVL, fee rate, 1-day and 7-day fee APR, and an APR flag, highest fee APR first. It does not read token contracts or the current tick. Call check_pool with a returned pool id for token flags. Not financial advice.
  - after: Use this when the user wants pools across chains or DEXes with recent volume and a fee rate, such as "high fee pools on Base with real volume". All arguments are optional: chains, min_volume_usd_1d (default 50000), min_fee_percent (default 0.05), and limit (default 5, at most 8). Returns each pool's id, volume, TVL, fee rate, 1-day and 7-day fee APR, and an APR flag with its reason, highest 1-day fee APR first. A small pool with a one-day volume spike can rank first, so check tvl_usd and apr_flag before you lead with it, or raise min_volume_usd_1d. It does not read token contracts or the current tick. Call check_pool with a returned pool_id for token flags and the risk checklist.
- 2026-10-10 `check_pool` changed (description, inputSchema, outputSchema)
  - before: Use this when the user asks about one liquidity pool, such as "volume and fee APR for WETH and USDC on Ethereum" or "is this pool APR a spike?". Pass a pool id, or chain plus token_a and token_b (symbols or token addresses). Optionally pass a price range, holding_days, and gas or exit amounts for the fee-versus-IL estimate. Returns 1-day and 7-day volume and fee APR, TVL, an APR flag with a reason, a risk checklist with warnings, price trend, token risk flags when a public source covers them, and an informational position-type label. A pool contract address is not in the index: the answer says needs_tokens and what to pass instead. Not financial advice, and it does not recommend entering or leaving a position.
