• get_protocol_tvlA

  TeardropA

  Get Total Value Locked for one or many DeFi protocols from DeFiLlama: current USD TVL, 7/30-day change, fees and revenue when reported, per-chain breakdown, and optional daily historical series. Batch multiple protocols via protocols=[...] — batch responses return one compact economic summary per protocol; single-protocol calls add chain and historical detail. Supports 3,000+ protocols; use DeFiLlama slugs ('aave-v3', 'uniswap-v3'); common aliases are auto-corrected. Use when: Use for protocol-level economic questions — size, growth, fees, or revenue of a specific protocol. For 2+ protocols always batch in one call rather than calling per-protocol. Pass include_historical=true with days when a trend is needed; without it the response is a current TVL scalar. For ecosystem-level chain comparisons use get_chain_metrics instead. Limitations: Third-party DeFiLlama analytics, not on-chain truth. Upstream revenue failures surface as revenue_error_type and null economic fields are data gaps — never fabricate values for them. Alternatives: get_chain_metrics, get_yield_rates, get_dex_volume

• validate_pythonA

  Python Code ValidatorA

  Check Python source without running it: parse, lint (ruff), type-check (mypy), AST security policy, credential scan. Safe on code you do not trust. Use it on every Python file you generated or edited, before writing it to disk. Alternatives: repair_python to get the corrected source instead of the diagnosis; execute_python to prove the code runs. Auth: a key is required. A free key covers this call, 25 per day, then HTTP 429; get one with POST /v1/keys. Credits are bought without an account, 1 per call: GET /v1/pricing says where to send the xDAI. Or pay for this one call with no key at all: call it without one and the result carries x402 payment requirements ($0.01 in USD Coin on eip155:8453); sign them and repeat the call with the payment in _meta['x402/payment']. Arguments: code: the whole file, 1..200000 bytes of UTF-8 measured after encoding (empty is refused with 400, larger with 413); a fragment is fine, but line and column numbers in the answer count from 1 in what you sent. language: must be 'python'; anything else is 400, and the field may be omitted. Of options only transpile_to (e.g. 'javascript', which returns a translated copy in transpiled) acts here; timeout_s, max_iterations, optimize, examples and expected_output need a pass that rewrites or runs the code, so send code alone. Ignored options are not refused, so a call that sets them looks like it worked; and code that does not parse is answered rather than refused: valid=false with the syntax error located, which is the point. Returns valid, score 0..1, diagnostics (rule, message, line, column), security findings, fixes, fixed_code and runtime; see outputSchema. The code and its verdict are retained to improve the service.

• defi_protocolsA

  MCPFax Macro & Market IntelligenceA

  Rank DeFi protocols by total value locked from DefiLlama, filtered by chain, category or name substring, with each protocol's slug, category, chain list, TVL in USD, 1d/7d TVL change and market cap. Use it to size a protocol, find the biggest venues on a chain, or resolve the slug the protocol-detail tool needs. A protocol DefiLlama publishes no TVL for keeps a null figure, never a zero. Read live at request time and held for 5 minutes. Costs $0.008 USDC per call via x402 on Base; an unpaid call returns the payment challenge instead of data, and a call that returns no data is never settled so it costs nothing. Equivalent HTTP route: GET /defi/protocols.

• get_wallet_positionsA

  TeardropA

  Get a wallet's DeFi positions across all DeBank-supported chains and protocols. Returns protocol-level positions, asset/debt/net USD values, optional token lists, aggregate exposure, and optional all-chain net worth. Set include_token_balances=true to also return DeBank's complete cross-chain wallet token list. Set include_token_lists=false for a compact balance and debt summary without nested position tokens. This covers substantially more protocols and chains than the block-accurate get_defi_positions tool. Use raw-RPC tools for liquidation, swap quotes, or other transaction-critical questions. Use when: Use for broad wallet discovery, portfolio allocation, protocol exposure, or cross-chain position questions. Set include_token_balances=true when complete wallet token discovery is required; otherwise the response only includes tokens attached to protocol positions. Set include_token_lists=false when only protocol balances, debt, or aggregate exposure are needed. Use get_defi_positions when the user needs a block-accurate Aave, Compound, Uniswap, or Lido snapshot. Limitations: DeBank portfolio data is third-party analytics and may be stale, including occasional long refresh delays. It is read-only, EVM wallet oriented, and does not prove current liquidation or execution state. include_token_balances adds a separate billable DeBank request; include_token_lists only changes response detail. Alternatives: get_defi_positions, get_wallet_portfolio, get_token_approvals

• search_problemsA

  Said It HereA

  Search SaidItHere for real-world software dilemmas, framework gotchas, tool fatigue, and battle-tested community consensus workarounds from Reddit, Hacker News, GitHub, and Stack Overflow. Usage Guidelines: - Primary discovery tool: use FIRST when investigating bugs, library gotchas, unexpected price hikes, or developer complaints by keywords. - Sibling routing: follow up with 'get_problem(slug)' using the discovered dilemma slug to inspect full evidence quotes, sources, and step-by-step workarounds. - Sibling routing: if 0 matching dilemmas are returned, use 'suggest_dilemma' to queue the topic for crawler consensus synthesis. - Do NOT use for generic language syntax lookups or textbook documentation queries. Behavior & Side Effects: - Pure read-only, safe, and idempotent query without side effects. Does not modify user, session, or database state.

• get_wallet_approvalsA

  TeardropA

  Inspect a wallet's current ERC-20 token authorization exposure on one DeBank-supported chain. Returns discovered spenders, USD exposure, protocol attribution, and hacked or abandoned protocol flags. This is broader than the curated block-accurate get_token_approvals tool. Use when: Use when broad spender discovery or cross-chain security screening is needed. Call once per chain because DeBank requires a chain_id. Use get_token_approvals for a free, block-accurate Ethereum or Base scan of curated tokens and spenders. Limitations: The result is third-party analytics and may be stale. It covers token approvals only, not NFT approvals or off-chain Permit2 sub-permits; each chain consumes a separate billable provider call. Alternatives: get_token_approvals

• get_wallet_historyA

  TeardropA

  Get one page of decoded transaction history for an EVM wallet across DeBank-supported chains. Returns send, receive, and approval categories with protocol, token, exchange, gas, and USD metadata. Use the returned next_cursor as start_time to page backward. Use when: Use for wallet activity discovery, protocol interaction history, exchange exposure, and gas analysis. Page backward with next_cursor for older activity. Use get_transaction or decode_transaction when one known transaction needs block-level details. Limitations: DeBank returns at most 20 entries per call and the data may be stale. This tool is not a complete ledger, PnL engine, or cost-basis calculator because historical execution prices and all transfer semantics are not guaranteed. Alternatives: get_transaction, decode_transaction

• check_tlsa_daneA

  IntoDNS.ai DNS & Email Security ScannerA

  Read-only TLSA/DANE DNS record check. With no port, resolves MX hosts and validates their `_25._tcp` TLSA tuple syntax; with an explicit port, queries `_<port>._<protocol>.<domain>`. Returns parsed usage, selector, matching type, certificate data, syntax errors, and best-practice advisories. It does not fetch or cryptographically match the live service certificate, so pair it with check_smtp_tls for SMTP certificate evidence. Use before publishing DANE records or troubleshooting DANE handover. No auth or destructive actions.

• explain_solutionA

  Moltline OptimizeA

  Plain-language summary of a solution from this server and the constraints that bind. FREE. Typical input {"solution": <result of route_plan_fleet>} returns {"summary": "2 vehicles serve 14 stops over 96.4 km; 1 stop unserved", "binding_constraints": ["van2 is at 100% of capacity", "stop C arrives at the end of its window"], "status": "FEASIBLE"}. It recognises results from route_plan, route_plan_fleet, pack_bins, cutting_stock_1d, cutting_stock_2d, roster_shifts and knapsack_select by their fields. Use to turn solver output into a message for a dispatcher or a shop floor. Not a re-solve. Errors: on invalid, missing, or malformed input this tool never raises a protocol error; it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "solution must be the result object returned by a solve tool on this server"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

• validate_pythonA

  CodeCraftA

  Validates a Python automation script that runs OUTSIDE the game, on three axes: Python syntax (using the real interpreter), Minecraft commands embedded in the script (against the official command index), and the shape of the /connect WebSocket message envelope. For behavior pack scripts use validate_script instead — Python does not run inside a pack. The embedded command check is the most valuable one: a command written from memory can look syntactically fine and still do nothing in the game. Only strings starting with / are treated as commands. If syntax could not be checked, syntaxChecked is false in the result; ok:true alone does not mean the syntax is valid.

• annotate_paperA

  Scholar FeedA

  Record YOUR verdict on a paper — why it matters for your work, when to use it, or why you ruled it out. One note per paper, upserted (writing again replaces it), so it is safe to call repeatedly. Requires SF_API_KEY. WHY IT MATTERS: this note is the only thing that survives between sessions. list_library returns note_text on every saved paper, so a verdict written now is what a future session reads INSTEAD of re-reading the paper and re-deriving the same conclusion. WRITE A JUDGMENT, NOT A SUMMARY — the paper already carries llm_summary and an abstract, so restating what the paper says adds nothing. Write what those cannot: how it bears on YOUR problem. Prefer a claim someone could later prove wrong ("needs a labeled trace log we don't have", "our baseline — beat this on the 7B setting") over an unfalsifiable verdict ("interesting", "not very relevant"), because a mechanism can be re-checked when circumstances change and a sentiment cannot. State the basis when it is thin: a verdict formed from the abstract alone deserves "(abstract only)", since fetch_fulltext defaults to ~800 characters of the results section rather than the whole paper. Pass action='get' to read the existing note before overwriting it — worth doing when a prior session may already have judged this paper. To correct a note, just write the corrected text (it replaces).

• knowledge_searchA

  AeviaA

  Search 130,000+ peer-reviewed sustainability papers and the account's uploads. Articles from Sustainability, the Journal of Cleaner Production, the International Journal of Life Cycle Assessment and the Journal of Industrial Ecology, 1993 to the present — LCA, material flows, energy, food and agriculture, materials, waste, buildings and policy. English-language; most entries are abstract and metadata only. Returns ref-numbered metadata only (title, authors, year, journal, DOI) — no abstract, no excerpts. Refs (e.g. `k1`, `k7`) persist for this session and are accepted by `knowledge_get_excerpts` (passages) and `knowledge_get_full_document` (the full paper). `limit` defaults to 12; a larger limit suits broad literature surveys. Optional filters: `journal` (its full name) and `year_from` / `year_to`.

• lookup_rfcA

  Dev Facts CheckA

  Use this when the user asks about an RFC, such as "which RFC obsoletes RFC 2616?" or "find the RFC about WebSocket". Pass either the RFC number, or words from its title (not both). A number returns the title, status, publication date, authors, abstract, and the RFCs it obsoletes, is obsoleted by, updates and is updated by. Title words return up to five matching RFCs with their numbers: call again with a number for the details.

• meetings_summarizeA

  Agentic EndpointsA

  Ask a plain-language question and get a written answer grounded in the user's own meeting transcripts, with the meeting id cited after each claim. Prefer this over meetings_search when the user wants an ANSWER ('what did we decide about pricing?', 'who owned the migration?') rather than a list of excerpts to read themselves. Pass the question as the user asked it -- this is NOT FTS5 syntax, and the terms actually searched come back as `terms` so you can check the retrieval. IMPORTANT: a 'no_matches' status means no answer was generated, and 'searched_meetings': 0 means every meeting is private and NOTHING was read -- neither is evidence the topic was never discussed, and you must not report it as such. Meetings imported as private are encrypted and can never contribute to an answer; `private_meetings_skipped` says how many were left out. A 'truncated' meeting in `consulted` had only part of its transcript read, so its silence on a point is not evidence either. Costs $0.050 in USDC on Base, paid via the x402 protocol, or from a credit token — call credits_trial for free credit if you have neither.
