Model Context Protocol (MCP) server for freee API integration
EchoLedger is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.
What it does
Live LP analytics — Uniswap V2/V3, Balancer, Curve stableswap: PnL, health, slippage, depeg risk.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http echoledger-mcp https://mcp.echoledger.ai/mcp
# 2 — ask your agent for something these tools do
# AnalyzePosition, AnalyzeBalancerLP, AnalyzeStableswapLP and 8 more
EchoLedger costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.

One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
11 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

| block_number | integer | no | Optional block number to pin the read to a historical block. Omit to read the latest block. |
Analyze a 2-asset Balancer weighted-pool LP position's PnL. Decomposes impermanent loss using the weighted-pool formula where the base token's weight affects IL magnitude. Values are denominated in opp-token units per BalancerImpLoss's convention; fee income is not attributed in v1 because Balancer pools only expose vault-level fees with no per-LP attribution.

| block_number | integer | no | Optional block number to pin the read to a historical block. Omit to read the latest block. |
Analyze a 2-asset Curve-style Stableswap LP position's PnL using the amplified-invariant IL formula where small depegs can produce surprisingly large IL at high A. Values are in peg-numeraire (tokens valued 1:1); fee income is not attributed in v1 (pool-global only); positions whose implied alpha is in the unreachable regime return None on il_percentage, net_pnl, and real_apr.

Project a Uniswap V2 or V3 LP position's value at a hypothetical price change from the CURRENT pool state (not from entry). A price_change_pct of -0.30 asks 'what if price drops 30% from here'. Returns new value, IL at the simulated price, and percentage change in position value. Fee projection is not modeled (always null).
| Parameter | Type | Required | Notes |

Project a 2-asset Balancer weighted-pool LP position's value at a hypothetical price change from the CURRENT pool state. The shock is applied to the base-token price in opp units; IL depends on both the shock magnitude and the pool's weights. Returns new value in opp-numeraire, IL at the simulated price, and percentage change.
| Parameter | Type | Required | Notes |
|---|---|---|---|

Project a 2-asset Curve-style Stableswap LP position's value at a hypothetical depeg from the CURRENT pool state. The shock multiplies the pool's current alpha by (1 + price_change_pct); at high A, large shocks may be physically unreachable and in that case new_value, il_at_new_price, and value_change_pct are returned as null. Values are in peg-numeraire.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| price_change_pct | number | no | Fractional shock applied to current alpha. Must be > -1.0. Simulated alpha = current_alpha * (1 + price_change_pct). |

Snapshot pool-level health metrics for a Uniswap V2 or V3 pool: TVL in token0 numeraire, reserves, accumulated fees, LP concentration, and swap activity. Answers 'is this a pool I would deposit into?' at the pool level (not position level). num_swaps and fee_accrual_rate_recent are V2-only; V3 returns null for these because V3 has no per-swap history array. A single-block live snapshot also return

Detect rug-pull signals on a Uniswap V2 or V3 pool via three threshold checks: suspiciously low TVL, top-LP concentration above a limit, and inactive-pool-with-liquidity. Composes over CheckPoolHealth and returns per-signal booleans plus a count-based risk level (low/medium/high/critical). The inactive-with-liquidity signal is V2-only; V3 pools report False for it with a note in details.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| lp_concentration_threshold | number/null | no | Top-LP share (strict-greater-than) that triggers the concentration signal. In (0, 1]; default 0.90; pass 1.0 to disable. |
| tvl_floor | number/null | no | Minimum acceptable TVL in token0 numeraire. Values at or below fire the tvl_suspiciously_low signal. Default 10.0 is nominal; override for your pair. |

Calculate slippage and price-impact decomposition for a proposed swap on a Uniswap V2 or V3 pool. Returns spot vs execution price, slippage percentage, slippage cost in output-token units, and price impact. Also returns the maximum trade size that stays within 1% slippage for V2 pools; V3 returns null for that field because tick-crossing math has not yet been inverted.
| Parameter | Type | Required | Notes |

Quantify a 2-asset Curve-style Stableswap LP position's exposure to a stablecoin depeg. Computes IL at multiple depeg levels (default 2%, 5%, 10%, 20%, 50%) via the closed-form stableswap-invariant expansion, with an optional V2 constant-product benchmark at each level. Some depeg levels are physically unreachable at high A — unreachable scenarios return null on il_pct, lp_value_at_depeg, and hold

| depeg_token_name | string | no | Optional. Symbol of the asset assumed to depeg (e.g. 'USDC', 'DAI'). Must be one of the two tokens in the pool. If omitted, the pool's first token is used. |
Read a pool's on-chain state once and return it as a serialized State Twin (JSON): the protocol-specific snapshot plus a content_hash, in the wire form a client rehydrates locally. Use this to pull a single managed-RPC twin, then run any number of counterfactuals (price moves, IL, slippage) client-side, off this server.

Nothing here is billable: mcprush charges nothing to install EchoLedger or to call it, at any volume.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither: the repository linked on this page is where this record was collected from, not a copy of what the address serves, so it is not graded in its place. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 0.2.3.
No release note was published with this version.
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Any signed-in account that does not publish EchoLedger can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
