Velora MCP server tools

The Velora MCP server exposes 9 tools and 5 read-only resources. Tool and parameter names below are verbatim from the server’s public contract; the contract is stable, so agents can hardcode against it.

Response envelope

Every tool returns the same envelope:

{
  "result": {},
  "agentHints": [],
  "docs": [{ "title": "...", "url": "https://velora.xyz/docs/...", "uri": "velora://docs/..." }],
  "warnings": []
}

result — the tool-specific payload. Raw API responses appear unmodified under result.raw.
agentHints — the next safe step, as plain strings. Follow them.
docs — links into this documentation relevant to the result.
warnings — user-facing caveats (for example, the sign-externally reminder on every built transaction).

Errors use the same envelope with isError: true and result.error.{type, message}. Validation failures and documented upstream errors surface their errorType and details; unexpected failures stay generic.

Quoting and building

velora_get_quote

Get a Velora quote. Delta, Market, or both modes via the unified quote endpoint.

Parameter	Type	Required	Notes
`chainId`	number	Yes	Always `chainId`, never `network`.
`destChainId`	number	No	Set for Crosschain quotes. Crosschain is Delta-only; `mode=MARKET` with a different `destChainId` is rejected before any API call.
`srcToken`	string	Yes	Token address. Native token placeholder: `0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE`.
`destToken`	string	Yes	Token address, same format.
`amount`	string	Yes	Raw units (wei-style), digits only.
`srcDecimals`	number	Yes	Source token decimals.
`destDecimals`	number	Yes	Destination token decimals.
`side`	`"SELL"` \| `"BUY"`	Yes
`userAddress`	string	No	The wallet that will execute.
`mode`	`"DELTA"` \| `"MARKET"` \| `"ALL"`	No	Default `ALL`. Use `DELTA` for MEV protection, Limit Orders, TWAP, and Crosschain.
`partner`	string	No	Your partner key; `my-app-name` is the placeholder to replace.

Returns { modeRequested, responseType, raw } where responseType is "delta", "market", or "unknown" and raw is the upstream payload, preserved unchanged. Agent rules:

Branch on responseType, never on what you requested. mode=ALL returns either a Delta or a Market response, never both.
A Delta quote is completed through the Delta path (POST /v2/delta/orders/build, sign externally, POST /v2/delta/orders) — not through velora_build_transaction. The quote’s agentHints repeat these steps.
Preserve the delta payload and its hmac exactly. Never normalize, reconstruct, or mutate it.
Under mode=ALL, a Delta pricing failure falls back to Market and surfaces a structured fallbackReason in warnings.

velora_build_transaction

Build an unsigned Market swap transaction from a quote’s priceRoute. Market only.

Parameter	Type	Required	Notes
`chainId`	number	Yes
`srcToken`	string	Yes	Token address.
`destToken`	string	Yes	Token address.
`srcAmount`	string	Yes	Raw units.
`destAmount`	string	Yes	Raw units.
`userAddress`	string	Yes	The wallet that will sign and send.
`priceRoute`	object	Yes	Copied verbatim from the Market quote’s `priceRoute`.
`partner`	string	No	Your partner key.

Returns result.raw with the unsigned transaction fields: from, to (the Augustus v6.2 router), value, data, gas pricing, and chainId. Agent rules:

The transaction is never signed here. Every response carries the warning “Review and sign externally with the user’s wallet.”
Delta-shaped input (anything containing delta, orderType, or alternatives keys) is rejected with an error pointing to the Delta build → sign → submit path.

Agent guidance

These three tools are deterministic, rule-based logic. They make no network calls and involve no model, so the same input always produces the same answer.

velora_decide_execution_route

Decide whether a trading intent should use Delta, Market, ALL, or none of the quote modes. Call it before velora_get_quote when the mode is unclear.

Parameter	Type	Required	Notes
`userIntent`	string	Yes	The user’s request, free-form.
`chainId`	number	No
`destChainId`	number	No	A different `destChainId` forces the Crosschain (Delta) rule.
`srcToken`	string	No
`destToken`	string	No
`amount`	string	No
`side`	`"SELL"` \| `"BUY"`	No

Returns { recommendedMode, reasoning } where recommendedMode is "DELTA", "MARKET", "ALL", or "NONE". Rule precedence (first match wins): OTC intent → NONE (it’s the AugustusRFQ maker/taker flow, not a quote mode) · MEV protection → DELTA · Crosschain → DELTA · Limit Orders → DELTA · TWAP or DCA → DELTA · explicit Market → MARKET · explicit Delta → DELTA · best-execution language → ALL · default → ALL.

velora_explain_quote

Classify a raw quote response and return the safe completion path. Never mutates the payload.

Parameter	Type	Required	Notes
`raw`	object	Yes	The `result.raw` from `velora_get_quote`.
`modeRequested`	string	Yes	The mode you passed to the quote call.

Returns { responseType, summary, fallbackReason }. A top-level delta key classifies as "delta", a top-level market key as "market", anything else as "unknown". fallbackReason ({ errorType, details }) appears when Delta pricing was skipped under mode=ALL.

velora_validate_agent_plan

Check a free-form plan against the mistakes agents actually make with Velora, before any of them execute.

Parameter	Type	Required	Notes
`plan`	object	Yes	Your plan as a free-form JSON object.

Returns { issues }, each issue carrying severity ("info", "warning", or "critical"), message, and fix. Checks include: a network key anywhere in the plan (must be chainId), MEV intent with a non-Delta mode, Crosschain with mode=MARKET, Limit Orders or TWAP treated as RFQ, and any signing, private-key, or Delta-payload-mutation step (critical — the server never signs).

Market data

velora_get_supported_chains

List the EVM chains Velora supports. No parameters. Returns result.raw.chains as { chainId, name } pairs with source: "server-known": Ethereum (1), Optimism (10), BNB Chain (56), Gnosis (100), Unichain (130), Polygon (137), Sonic (146), Base (8453), Arbitrum (42161), Avalanche (43114). This is a server-known list, not a live API response, and may lag actual support. Confirm a specific chain with velora_get_tokens; do not assume every EVM chain is supported.

velora_get_tokens

List the tokens Velora can route on a chain. Use it to resolve token addresses and decimals before quoting instead of inventing them.

Parameter	Type	Required	Notes
`chainId`	number	Yes	Always `chainId`, never `network`.

Returns result.raw.tokens as { symbol, address, decimals, img, network } entries.

Documentation

velora_search_docs

Search Velora’s canonical documentation. Use it before guessing Velora behavior.

Parameter	Type	Required	Notes
`query`	string	Yes
`limit`	number	No	1–20, default 5.

Returns search results as { title, url, resourceUri, snippet }.

velora_get_docs_page

Fetch a single docs page as markdown by its slug.

Parameter	Type	Required	Notes
`slug`	string	Yes	A docs slug such as `integrate/trading-modes`. Absolute URLs and path traversal are rejected.

Returns { slug, content }.

Resources

Five read-only documents an MCP client can pull straight into context:

Resource URI	What it is	When to read it
`velora://docs/llms`	The docs index (`llms.txt`), a compact map of the documentation.	First. Orient before fetching pages.
`velora://docs/llms-full`	The full documentation concatenated.	When you need authoritative detail and have the context budget.
`velora://docs/openapi/delta-v2`	OpenAPI spec for the Delta v2 intent API.	Generating or checking Delta integration code.
`velora://docs/openapi/market`	OpenAPI spec for the Market aggregator API.	Generating or checking Market integration code.
`velora://docs/openapi/rfq`	OpenAPI spec for AugustusRFQ (OTC maker/taker).	OTC flows. RFQ is not a quote mode.
