10 tools

• review_framework_code

  Scan source against known dead APIs (LLMChain, initialize_agent, ServiceContext, ripple-lib, …) and return each hit with replacement plus a unified-diff hunk. Use before running agent-written code; diagnose_framework_error is for after a stack trace. Does not execute or submit…

• rewrite_framework_code

  Apply conservative catalog rewrites (imports/identifiers) to a snippet and return the patched file plus a full unified diff. Use when review_framework_code found hits and you want an applyable file. Leftover lists unsafe call-site transforms (e.g. LLMChain(...)) that stay for a…

• diagnose_framework_error

  Match a stack trace or exception against known deprecated APIs for langchain, llamaindex, ollama, or xrpl and return the replacement plus a fix. Use only when you have an error_log; matched=false means no catalog hit — then search_ai_framework_docs with the failing symbol. Lint…

• resolve_symbol

  Map an API name to the current package, install line, import, and call shape (ChatOpenAI, create_agent, VectorStoreIndex, xrpToDrops, …). Use when you know the symbol but not where it lives. Prefer search_ai_framework_docs for concepts and fetch_latest_syntax for topic snippets…

• fetch_working_example

  Fetch one complete runnable file (filename, install/run, source) for a goal such as agent, rag, chat, payment, or rlusd. Use when fetch_latest_syntax snippets are too small to execute. matched=false means no catalog example — then fetch_latest_syntax. Paid tools/call: $0.001…

• fetch_latest_syntax

  Curated working imports, snippets, and migration notes for one topic (agents, rag, wallet, payment, trustlines, …). Use when writing or migrating a fragment; unknown topics fall back to related doc chunks instead of failing. Prefer fetch_working_example for a complete runnable…

• search_ai_framework_docs

  Keyword search over a local Markdown index for langchain, llamaindex, ollama, or xrpl; returns compact chunks and never live-crawls. Use for concepts, symbols, or questions; hitCount 0 means no match — shorten the query. Do not use for stack traces (diagnose_framework_error)…

• draft_xrpl_intent_tx

  Draft a typed xrpl.js / xrpl-py skeleton for payment, trustline, rlusd, or channel, plus required fields and common tec/tem failure codes. Use when building an XRPL tx; never submits, signs, or moves funds. Prefer fetch_working_example for a full script and review_framework_code…

• list_supported_frameworks

  List the framework ids this server covers (langchain, llamaindex, ollama, xrpl) with display names, aliases, homepages, and catalog topics. Use when you do not know which framework string to pass. Free tools/call (no x402). Not a docs search (search_ai_framework_docs) and not a…

• list_known_deprecations

  Return the known-deprecated API catalog (id, old API, replacement, fix) for one framework or all four at once. Use when you want the full deprecation list without a stack trace or source snippet. Prefer diagnose_framework_error when you have an error_log and…
